The Axial Skeleton

The skeleton is subdivided into two major divisions—the axial and appendicular. The axial skeleton forms the vertical, central axis of the body and includes all bones of the head, neck, chest, and back (Figure 7.2). It serves to protect the brain, spinal cord, heart, and lungs.

How many bones are in the axial skeleton and the appendicular skeleton?

The axial skeleton forms the vertical axis of the body and includes the bones of the head, neck, back, and chest of the body. It consists of 80 bones that include the skull, vertebral column, and thoracic cage. The appendicular skeleton consists of 126 bones and includes all bones of the upper and lower limbs.

Why is it called the axial skeleton?

These bones are divided into two main parts: Your appendicular skeleton and your axial skeleton. Your axial skeleton is made up of the bones along your vertical axis. Axial comes from the word “axis,” which means line. The bones line up along the central core of your body.

What are the three main parts of the axial skeleton quizlet?

Are hip bones axial or appendicular?

The hip bone, or pelvic bone, is not part of the axial skeleton. It is part of the appendicular skeleton. The axial skeleton is made up of the bones in the skull, the face, vertebral column, and rib cage. All other bones in the body are part of the appendicular skeleton.

Which way is axial?

Axial loads occur parallel to the direction of motion, while radial loads occur perpendicular to the direction of motion.

What are the appendicular skeleton?

The appendicular skeleton is comprised of the upper and lower extremities, which include the shoulder girdle and pelvis. The shoulder girdle and pelvis provide connection points between the appendicular skeleton and the axial skeleton to where mechanical loads transfer.
