What are the components of the axial skeleton?
The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton.
What does the axial skeleton do?
The axial skeleton consists of the braincase (cranium) and the backbone and ribs, and it serves primarily to protect the central nervous system. The limbs and their girdles constitute the appendicular skeleton.
Which of the following is a function of the axial skeleton quizlet?
The axial skeleton supports the head, neck, back, and chest of the body and allows for movements of these body regions. It also gives bony protections for the brain, spinal cord, heart, and lungs; stores fat and minerals; and houses the blood-cell producing tissue.
What protects the spinal cord of the human body?
vertebraeA protective layer of bone called the vertebral column covers and protects your spinal cord. The bones in the vertebral column are called vertebrae (plural of one spine bone, a vertebra).

What is the axial skeleton?
The axial skeleton supports the head, neck, back, and chest and thus forms the vertical axis of the body. It consists of the skull, vertebral column (including the sacrum and coccyx), and the thoracic cage, formed by the ribs and sternum. The appendicular skeleton is made up of all bones of the upper and lower limbs.

It is present on the dorsal side of the thorax region and forms the dorsal part of the thoracic cage. Lumbar: Lumbar vertebrae are 5 in number. They form the dorsal part of the abdomen, i.e. lower back.
Which skeleton is responsible for the central axis of the body?
The axial skeleton constructs the central axis of the body, while the appendicular skeleton comprises the limbs and girdles.
How many bones are there in the skull?
The two parts of the skull are the cranium and facial bones. The skull of humans is said to be dicondylic. The skull consists of 29 bones, i.e. 8 in the cranium, 14 in the face, 6 ear ossicles and 1 hyoid bone.
What is the human skeletal system?
