1

This is the base of a skull. Identify the external occipital protuberance, mastoid process, superior and inferior nuchal lines.

*

2

Identify the vertebral foramen, body, spinous process, transverse process, pedicles, laminae, articular facets and processes, and vertebral arch.

*

3

What is labeled IV in this picture?

Intervertebral foramen

4

How do cervical, thoracic and lumbar vertebrae differ?

Cervical have transverse foramina, thoracic look like elephants and lumbar are large.

5

Identify the spine, acromion, superior angle, inferior angle, medial border, supraspinous fossa and infraspinous fossa.

This has everything but the superior and inferior angles which are logically the points on the top and bottom of the scapula.

6

Identify the iliac crest and posterior iliac spine.

*

7

Identify the trapezius, latissimus dorsi, rhomboid major, rhomboid minor, levitator scapulae, serratus posterior superior, serratus posterior inferior, splenius and erector spinae.

*

8

Where is the spinal accessory nerve located? What does it run with?

Deep in the trapezius. Transverse cervical artery.

9

Find the thoracodorsal nerve and artery.

*

10

How long before the transverse cervical artery joins the spinal accessory nerve?

It originates in the thyrocervical arterial trunk (5). It branches from this trunk as the transverse cervical artery (4) and branches down to join the spinal accessory nerve in the trapezius muscle.
