Overview: muscles of neck and trunk - Charlotte Flashcards
What does the cervical ventral muscles do?
Chiefly, flexors of the neck.
What does the cervical dorsal muscles do?
Extensor of the neck.
What does the deep juxtavertebral muscles do?
Are involved in Rotation and lateral flexion
The muscles of the poll
Extension and lateral flexion of the head.

Juxtavertebral muscle Of the trunk
Multifidus (transverse spinous)
What are the two major system of the muscles of the neck & trunk?
The deep juxtavertebral muscles, responsible for maintaining control of the intervertebral joints. Highly innervated, propriorception they are the source for postural information. 2) the superficial paravertebral muscles, which are less richly innervated, thus less information for tonus and posture. Major locomotor muscles though.
