1. Definitions:

a. Hemorrhage- Loss of blood from the vessels by flow through ruptured walls; bleeding.

b. Fracture- A break in a bone.

c. Proximal- Toward the attached end of a limb or the origin of a structure.

d. Diaphysis- Elongated shaft of a long bone

2. Bones can be classified by their shape. They're four different shapes that classify bones, which are long bones, short bones, flat bones, and irregular bones. Mrs. Morgan fractured three bones. She fractured her left humerus, occipital bone, and her 3rd lumbar vertebrae. The fractured left humerus is considered to be classified as a long bone. It is considered a long bong because the humerus bone is longer than it is wide The fractured occipital bone is considered to be classified as a flat bone. The occipital bone is considered a flat bone due to it being thin, flat, and slightly curved. Lastly the fractured 3rd lumbar vertebral body is considered to be an irregular bone due to it being a complicated shape (Marieb 2013).

3.The body of Mrs. Morgan's vertebra is fractured. The majority of the vertebral body is made up of spongy bone tissue. The structure of the lumbar vertebrae includes the vertebral body, posterior elements, inter-vertebral disks, and ligaments. The lumbar spine is made up of the five lumbar vertebrae, which is located between the thoracic spine and the sacrum. This area is commonly referred to as the “lower back”. The lumbar vertebrae are the largest of the vertebrae because of their weight-bearing function supporting the torso and head. The lumbar vertebrae also functions in allowing for mobility and flexibility to absorb energy and protect against impact (Schmidler 2014).

4.The diaphysis of Mrs. Morgan's humerus is fractured. Compact bone also known as cortical bone makes up the majority of the diaphysis of long bones such as the humerus. Long bones, such as those of the limbs, wrists, and ankles are...
