During a musculoskeletal examination, the clinician instructs the patient to look over one shoulder, and then the other shoulder. This action assesses the movement of which muscle(s)? a. Scalenes
b. Sternocleidomastoid (SCM) c. Splenius capitis
d. Prevertebral muscles
e. Splenius cervicis Correct Answer and Rationale- b. Sternocleidomastoid (SCM)
Rationale: The action is rotation of the neck. The muscles responsible for rotation of the neck are the SCM and the small intrinsic neck muscles. Scalenes is incorrect; the action of the scalene muscle is to flex the neck. The scalenes also laterally bend the neck. Splenius capitis is incorrect; the action of the splenius capitis muscle is to extend the neck. Prevertebral muscles is incorrect; the action of the prevertebral muscles is to flex the neck. Splenius cervicis is incorrect; the action of the splenius cervicis muscle is to extend the neck.
During a musculoskeletal examination of the spine, what is the action(s) of the erector spinae muscle group?
a. Rotation of the spine b. Extension of the spine c. Flexion of the spine
d. Lateral bending of the spine
e. Rotation and lateral bending of the spine Correct Answer and Rationale- b. Extension of the spine
Rationale: The erector spinae muscle group is one of the deep intrinsic muscle groups of the back that extend the spine. Rotation of the spine is incorrect; the muscles that rotate the spine are the abdominal muscles and the intrinsic muscles of the back. Flexion of the spine is incorrect; the muscles that flex the spine are the psoas major and minor, quadratus lumborum, and the abdominal muscles. Lateral bending of the spine is incorrect; the muscles that laterally bend the spine are the abdominal muscles and the intrinsic muscles of the back.
