Which bones are a part of the axial skeleton?
Which bones are a part of the axial skeleton?
Tap to reveal answer
The skeletal system is divided into the axial skeleton and the appendicular skeleton. The axial skeleton consists of bones of the head, ribs, vertebral column, and sternum. In contrast, the appendicular skeleton consists of bones of the extremities, including the fingers, arms, and legs.

Tap to reveal answer
The bone that forms the shin is the tibia. This is palpable along the anterior surface of the lower limb. The fibula is also located in the lower leg, but is not part of the prominent ridge felt on the front of the leg, as it is deep. The femur is the bone found in the thigh. The mandible is the jaw bone.

The shaft of a long bone (such as the femur) is called the .
Tap to reveal answer
Long bones have a body that is longer than it is wide (such as the femur, humerus, and phalanges). It consist of a tubular shaft (diaphysis) with growth plates (epiphyses) at either end. The shaft is composed of a hard outer surface of compact bone with a spongy interior (cancellous bone) that contains bone marrow.
