Foot structure diagram diagram base website structure diagram

It may surprise you to know that the foot is one of the most complicated structures of the body. It contains a lot of moving parts - 26 bones, 33 joints and over ligaments. Such complexity is necessary because the foot is required to do many different activities such as walking, running and climbing.

Between them, the two feet need to balance the weight of the body, redistributing it in response to position changes. This is, if you'll pardon the pun, no mean feat. This consists of five long metatarsal bones and five shorter bones that form the toes phalanges. This is approximately pyramid-shaped and is comprised of three cuneiform bones, the navicular bone and the cuboid bone.

These form the arches of the feet. They are actually quite a miracle of engineering, forming a structure which is both flexible and sturdy.

This is comprised of the talus bone and the calcaneum. The talus connects with the tibia and fibula to form the ankle joint, and the calcaneum is the bone that forms the heel. The calcaneum is the largest bone in the foot. The muscles are located mainly in the sole of the foot and divided into a central medial group and a group on either side lateral. The muscles at the top of the foot fan out to supply the individual toes.

The tendons are thick bands that connect muscles to bones. When the muscles tighten contract they pull on the tendons, which in turn move the bones. Arguably, the most important tendon is the Achilles tendon, which allows the calf muscles to move the ankle joint.

The ligaments are fibrous bands - imagine very strong rubber bands - which bind the bones together to give shape, flexibility and strength to the foot. There are many ligaments in the foot.

Some run together to form complex webs around areas which need extra support, such as the sole of the foot, the top of the foot and the ankle joint.

We probably spend more time maintaining our cars than we do our feet. It's amazing how little care we give them, considering what complex machines they are and what we expect them to do.

However, when things do go wrong they soon start complaining! Foot pain should never be ignored, particularly if it occurs daily and becomes persistent. Simple hygiene measures will help reduce the risk of infection. However, don't soak them for hours as this affects the natural oils produced by the skin.

No quick wipe with a little towel. Really get between those toes and give them a good dry. Damp body surfaces are ideal breeding grounds for fungal infections such as athlete's foot. Use a moisturising cream regularly if you have dry skin but don't put it between your toes, as this area is best kept dry. Remove hard skin and callus with a pumice stone or foot file but be gentle.

Vigorous rubbing will only make the skin grow back harder and there is a danger of skin damage, which can make the area prone to infection. Cut your toenails with care, straight across and never down at the edges.

Cutting the nails at the corners can lead to accidental trauma to the skin and also increase the risk of ingrowing toenails. This might seem odd but as the day goes on, your feet get slightly larger. If you buy shoes in the morning, their is a risk they will be too tight, so it's best to shop in the afternoon.The skeletal structure of the foot is similar to that of the hand but, because the foot bears more weight, it is stronger but less movable.

The foot begins at the lower end of the tibia and fibula, the two bones of the lower leg. At the base of those, a grouping of bones form the tarsals, which make up the ankle and upper portion of the foot. There are five metatarsal bones in each foot. Similar to the bones of the hand, these nearly parallel bones create the body of the foot. Numbered one through five, the bone that sits behind the big toe is number one, and the one behind the little toe is number five.

The phalanges create the toes. Each toe consists of three separate bones and two joints, except for the big toe, which has only two bones — distal and proximal phalanges — and one joint, like the thumb in the hand. The phalanges are made up of the distal phalanges at the tip, middle phalanges, and proximal phalanges, closest to the metatarsals.

Bones are connected via fibrous ligaments. A web of ligaments surrounds the ankle and other parts of the foot, and the metatarsal bones are strung together by ligaments to keep them from stretching too far apart.

Each individual toe joint is wrapped in ligaments. Because of its number of bones, the foot also contains numerous pieces of cartilagea connective tissue that pads bones and joints. This cartilage can be damaged with excessive use or injury. Cartilage damage can cause joint pain. The corpus spongiosum is yet another part of the male anatomy that facilitates sexual reproduction.

The Holistics Blog. Share this.Structure lets you work with both structure the whole code-base as it is and architecture the subset of the structure that you really care about, and how it should be. It lets you define the architecture in the context of the physical structure and diseminate this to the team. Architecture diagrams are what makes this possible. Structure architecture diagrams use a concise visual notation for representing architectural layering and composition.

Here is an example of one of the architecture diagrams that we use for the structure code-base. Sometimes a top-down dependency structure is too simple to capture the intent of an architecture. For example we may decide to allow a specific dependency from a cell to a higher-level cell.

A more common example is where we wish to enforce a more strict layering. For example we may want one layer to only use the next layer down, but not layers below that. It is not necessary to include all aspects of an architecture on a single structure architecture diagram. For example, this diagram shows part of the structure architecture. It is correct, but incomplete. Classes in assemblies. X should never depend on classes in lang.

We could express this by adding several overrides, but it is much cleaner to use a separate diagram for this aspect of the architecture. The combination of the 2 diagrams defines the intended architecture. In order to understand how a physical code-base conforms to an intended architecture, we need to map the architectural components cells to physical code. Another flexibility is that a physical entity maps to the component with the most specific pattern. For example if I include 2 components, one with com.

The effects of this can be at the same time subtle and powerful.The foot is the lowermost point of the human leg. The structure of the foot is similar to that of the hand, but because the foot bears more weight, it is stronger and less mobile. The largest bone of the foot, the calcaneusforms what is commonly referred to as the heel. It slopes upward to meet the tarsal bones, which point downward along with the remaining bones of the feet. Below the juncture of these bones are the arches of the footwhich are three curves at the bottom of the foot that makes walking easier and less taxing for the body.

These arches — the medial arch, lateral arch, and fundamental longitudinal arch — are created by the angles of the bones and strengthened by the tendons that connect the muscles and the ligaments that connect the bones.

The bones of the foot are organized into rows named tarsal bones, metatarsal bones, and phalanges. These make up the toes and broad section of the feet. The other bones of the foot that create the ankle and connecting bones include:. Many of the muscles that affect larger foot movements are located in the lower leg. However, the foot itself is a web of muscles that can perform specific articulations that help maintain balance and flex as a person walks.

By following the principles on this page, you can design a database that performs well and adapts to future needs.

Want to make a database diagram of your own? Try Lucidchart. It's quick, easy, and completely free. Designing an efficient, useful database is a matter of following the proper process, including these phases:.

To learn more about database models, read our guide here. Understanding the purpose of your database will inform your choices throughout the design process. Make sure you consider the database from every perspective. Then list the types of data you want to store and the entities, or people, things, locations, and events, that those data describe, like this:.

This information will later become part of the data dictionary, which outlines the tables and fields within the database. Be sure to break down the information into the smallest useful pieces. For instance, consider separating the street address from the country so that you can later filter individuals by their country of residence.

Also, avoid placing the same data point in more than one table, which adds unnecessary complexity. The next step is to lay out a visual representation of your database.

To do that, you need to understand exactly how relational databases are structured. Within a database, related data are grouped into tables, each of which consists of rows also called tuples and columns, like a spreadsheet. To convert your lists of data into tables, start by creating a table for each type of entity, such as products, sales, customers, and orders.

Each row of a table is called a record. Records include data about something or someone, such as a particular customer. By contrast, columns also known as fields or attributes contain a single type of information that appears in each record, such as the addresses of all the customers listed in the table.

To keep the data consistent from one record to the next, assign the appropriate data type to each column. Common data types include:.

Some database management systems also offer the Autonumber data type, which automatically generates a unique number in each row. Instead, each table becomes a box in the diagram. The title of each box should indicate what the data in that table describes, while attributes are listed below, like this:. Finally, you should decide which attribute or attributes will serve as the primary key for each table, if any. A primary key PK is a unique identifier for a given entity, meaning that you could pick out an exact customer even if you only knew that value.

Attributes chosen as primary keys should be unique, unchanging, and always present never NULL or empty. For this reason, order numbers and usernames make good primary keys, while telephone numbers or street addresses do not.

You can also use multiple fields in conjunction as the primary key this is known as a composite key. At that point, you should also estimate the size of the database to be sure you can get the performance level and storage space it will require. Cardinality refers to the quantity of elements that interact between two related tables.

Database Structure and Design Tutorial

Each entity can potentially have a relationship with every other one, but those relationships are typically one of three types:. You can indicate this kind of relationship in an ER diagram with a line with a dash on each end:.In the previous chapters, we have discussed about the building blocks and other necessary elements of UML.

Now we need to understand where to use those elements. The elements are like components which can be associated in different ways to make a complete UML picture, which is known as diagram. Thus, it is very important to understand the different diagrams to implement the knowledge in real-life systems. Any complex system is best understood by making some kind of diagrams or pictures.

These diagrams have a better impact on our understanding. If we look around, we will realize that the diagrams are not a new concept but it is used widely in different forms in different industries. We prepare UML diagrams to understand the system in a better and simple way. A single diagram is not enough to cover all the aspects of the system. UML defines various kinds of diagrams to cover most of the aspects of a system. You can also create your own set of diagrams to meet your requirements.

Diagrams are generally made in an incremental and iterative way.

The structural diagrams represent the static aspect of the system. These static aspects represent those parts of a diagram, which forms the main structure and are therefore stable.

These static parts are represented by classes, interfaces, objects, components, and nodes. Class diagrams are the most common diagrams used in UML. Class diagram consists of classes, interfaces, associations, and collaboration.

Class diagrams basically represent the object-oriented view of a system, which is static in nature. Class diagram represents the object orientation of a system.

Hence, it is generally used for development purpose. This is the most widely used diagram at the time of system construction. Object diagrams can be described as an instance of class diagram. Thus, these diagrams are more close to real-life scenarios where we implement a system. Object diagrams are a set of objects and their relationship is just like class diagrams. They also represent the static view of the system. The usage of object diagrams is similar to class diagrams but they are used to build prototype of a system from a practical perspective.

Component diagrams represent a set of components and their relationships. These components consist of classes, interfaces, or collaborations. Component diagrams represent the implementation view of a system. During the design phase, software artifacts classes, interfaces, etc. Now, these groups are known as components. Deployment diagrams are a set of nodes and their relationships. These nodes are physical entities where the components are deployed.
