What vertebral landmark protects the spinal cord?
This muscle divides the anterior and lateral cervical muscle groups and is innervated by the spinal accessory nerve (CN XI)
Sternocleidomastoid (SCM)
The diaphragm inserts into this structure, which it draws downward and forward during inspiration.
The central tendon
What movement occurs in the sagittal plane?
(Bonus 50 points (each): What movement occurs in the transverse and frontal planes?)
Sagittal plane: flexion and extension
Transverse plane: twisting, rotation
Frontal plane: Abduction and adduction, elevation and depression
The diaphragm is innervated by this nerve
The phrenic nerve
(C3, C4, C5 keep the diaphragm alive)

1. Cervical
2. Thoracic
3. Lumbar
1. Transverse foramen (except C1 and C2)
2. Costal Facets
3. Mammillary process
This ligament limits hyperextension and is relatively thick but narrow in the thoracic region.
The body of the sternum lies at the level of these thoracic vertebrae
T5–T9
What is the difference between a tendon and a ligament?
A tendon connects muscle to bone
A ligament connects bone to bone
The costovertebral and costotransverse joints are classified as this type of joint.
plane synovial joints
A continuation of the supraspinous ligament, running from the external occipital protuberance and foramen magnum to the cervical spinous processes.
The nuchal ligament

4. Obliquus capitis inferior
1. This "handle" movement, from the ribs moving upward and forward, increases the anteroposterior diameter of the thorax.
2. This "handle" movement, from the ribs moving upward and laterally, increases the transverse diameter of the thorax
1. The pump handle movement
2. The bucket handle movement
