Q

The multifidis cervicis participates in what movements?

A

Alters the zigapophyseal capsular ligament in response to load distribution. Determines the cervical spine response to injury as evidenced by neck pain. Is a significant contributor to postural control of the head and neck.

Q

Based on the density of muscle spindles what is the proposed function of the intertransversarii?
