1
New cards

three major regions

Skull, Vertebral column, Thoracic cage

2
New cards

three functions of the axial skeleton

Form longitudinal axis of body, Support head, neck, and trunk, and Protect brain, spinal cord, and thoracic organs

3
New cards

The skull is formed by two sets of bones

carnium and facial bones

4
New cards

Cranial bones (cranium)

The skull encloses the brain and provides muscle attachment sites.

5
New cards

Facial bones

The skull forms the face, houses sense organs, anchors facial muscles, provide openings for air and food passage, and secure teeth

6
New cards

sutures

joints

7
New cards

Cranial vault (calvaria)

forms superior, lateral, and posterior portion of skull, as well as forehead

8
New cards

Cranial base

forms inferior aspect of skull

9
New cards

The internal cranial base (cranial cavity) is divided into three “steps,” or fossae

anterior, middle, posterior fossae

10
New cards

Other cavities found in the cranium

Middle and internal ear cavities, Nasal cavity, Orbits that house eyeballs

11
New cards

eight cranial bones

Frontal bone, Parietal bones (two—left and right), Occipital bone, Temporal bones (two—left and right), Sphenoid bone and Ethmoid bone

12
New cards

Coronal suture

between parietal bones and frontal bone

13
New cards

Sagittal suture

between right and left parietal bones

14
New cards

Lambdoid suture

between parietal bones and occipital bone

15
New cards

Squamous (squamosal) sutures

between parietal and temporal bones on each side of skull

16
New cards

Foramen magnum

“large hole” through which brain connects with spinal cord

17
New cards

Facial skeleton is made up of 14 bones

Mandible, two maxillary bones, two Zygomatic bones, two Nasal bones, two Lacrimal bones, two Palatine bones, Vomer and two Inferior nasal conchae
