Front 26

what artery ascends in the neck bilaterally through the transverse foramina?

Back 26

vertebral arteries

Front 27

the triangular area between the occipital bone and the posterior aspects of C1 and C2

- lies deep to the trapezuis and semispinalis capitis muscles

Back 27

suboccipital region

Front 28

this nerve is superficial to the suboccipital region but deep to the semispinalis capitis muscle
- provides sensation to the back of the head

Back 28

greater occipital nerve C2

Front 29

articulations between the lateral masses of C1 and the occipital condyles that permit flexion and extension
- synovial joints of the condyloid type and have thin, loose, articular capsules

atlantooccipital joints

Front 30

what connects the skull and C1 anteriorly and posteriorly?

they extend from the anterior and posterior arches of C1 to the anterior and posterior margins of the foramen magnum.

- prevent excessive movement of these joints
