Anatomy H/w Project Steve Brown Session 8

For this week's assignment we were tasked with learning about the human skeleton and learning the names of the major bones and joints in the human body, such as the Thorax - which is the rib cage/chest. I will be typing the names of the bones and what they are for those who may be unable to read my handwriting.

With this sketch of the skull I tried to create in a unique way. The skull is essentially made into 3 parts, the dome of the skull (containing the Frontal Bone and Parietal Bone), the Maxilla (containing the eyes sockets, Nasal Bone and top row of teeth) and finally the Mandible (essentially the jaw). So with this in mind I drew the skull in it's 3 separate parts.

This sketch encompasses the spine, shoulder blades and pelvis. the 5 vertebrae above the pelvis are mown as the Lumbar, and the rest of the vertebrae above are known as the Thoracic. The reason the spine is curved and segmented into vertebrae is for 2 reasons. 1st Is to help support body weight which is mainly supported by the legs and spine and 2nd is for shock absorption, the curvature causes energy from a shock to dissipate over a longer period rather than be concentrated into a singular column.

The shoulder blades are categorised and known in medicine as the Scapula.

Whilst sketching the ribs I decided to fill in the empty space between each rib, not only can this be seen as a representation of the skin on the back but also the contrast between the white ribs and black empty space emphasises the shape of each rib. 

The rib cage/chest as a whole is known collectively as the Thorax. The collar bones are known individually as a Clavicle. The ribs are all connected together at the front by a tough, flat bone known as the Sternum.

The bone in the upper part of your arm where the bicep is located is called the Humerus, which connects to the elbow joint, which again in itself connects to 2 more bones in the forearm. They are known as the Radius and Ulna, and like the spine they are designed this way to be a form of shock absorption, spreading the kinetic energy of an impact (regardless of what it is) between these 2 points.

This sketch is for all intents and purposes the same as the sketch I made for the arm. Where the thigh would be or comparatively where the bicep/Humerus would be on the arm is a singular solid bone called the Femur. The Femur is connected to the Tibia and Fibula through tendons, ligaments and the Knee cap. 

The Tibia and Fibula are to the lower leg what the Radius and Ulna are to the forearm, they all serve similar purposes (to absorb shock) and are located in the same position on their respective limbs.
