How many bones are in the axial skeleton?
80
1 of 82
What does the axial skeleton consist of?
The Skull, the thoracic cage, the vertebral column.
2 of 82
The axial skeleton provides a surface area for the attachment of muscles. What does these muscles do? (3 things)
1. Adjust the position of the head. 2. Perform respiratory movements. 3. Stabilize or position the appendicular skeleton.
3 of 82
What do the bones of the skull do?
Protect the brain and guard the entrances to the digestive and respiratory systems.
4 of 82
What are the 8 cranial bones?
The Occipital bone, the frontal bone, the sphenoid, the ethmoid, the parietal and the temporal bone.
5 of 82
What are the two major functions of the sinuses?
1. They make bone lighter. 2. They have a mucous membrane that moistens and clears the air adjacent to the sinus.
6 of 82
What is a suture?
Connections between the bones in the skull that are immovable joints.
7 of 82
What is the function of the occipital bone?
Forms much of the posterior and inferior surface of the cranium.
8 of 82
What is the function of the parietal bones?
To form the superior and lateral surface of the cranium.
9 of 82
What is the function of the frontal bone?
To form the anterior part of the cranium and the roof of the eye sockets.
10 of 82
What are the functions of the temporal bones?
To form part of both lateral walls of the cranium and they are attachment sites for muscles that close the jaw and move the head.
11 of 82
What is the function of the sphenoid bone?
Forms part of the floor of the cranium and unites the cranial and facial bones. Mucous secretions of the sphenoidal sinuses keep the nasal cavity clean.
12 of 82
What is the function of the ethmoid bone?
Forms another part of cranial wall, the roof of the nasal cavity and part of the nasal septum.

The vertebral column forms a canal through which the spinal cord runs.
