List and define ten medical terms pertaining to the skeletal system

Thorax

the bones of the thorax (ribs, sternum and thoracic vertebrae) form a cage which protects many of the body's vital organs.

The Axial skeleton

This is the main body including the pelvis, thorax, and skull (excluding the arms and legs).

The Proximal skeleton

The femur and humerus (ie the bones proximal to the Axial skeleton)

The Distal skeleton

The lower legs (tibia, fibula, and feet bones) and lower arm (radius, ulna, and bones of the hand). The Proximal and Distal skeleton are sometimes collectively referred to as bones of the extremities.

The spine

The spine is divided into 5 main areas and each bone (verebrae) has a letter and number:

Cervical vetebrae C1 - C7

the neck region. C1 is the upper most vertebrae.

Thoracic vertabrae T1 - T12

vertebrae of the upper body (thorax)

Lumbar vertebrae L1 - L5

vertebrae of the lower back

Bones of the sacrum S1 - S5

vertebra within the pelvic girdle. These bones fuse together between ages 16 and 18.

The coccyx Co1 - Co4

The lower tip of the spine. These bones fuse together between ages 20 to 30.
