Transcript and Presenter's Notes

Title: Identify the muscles of the neck and indicate their major actions and sources of innervation. Indicate the relationship of each of the muscle groups to the layers of deep fascia in the neck.


1
Identify the muscles of the neck and indicate
their major actions and sources of innervation.
Indicate the relationship of each of the muscle
groups to the layers of deep fascia in the neck.
Anterior triangles
Suprahyoidmuscles
Infrrahyoidmuscles
Prevertebral muscles
Scalene muscles

2
Identify the three pharyngeal constrictor muscles
and their anterior attachments to
bony/cartilaginous structures. Identify the three
small longitudinal muscles of the pharynx.
3
Identify the major cartilages of the larynx

and the muscles which bring about their
movement.
Arytenoideus
Cricothyroid
Posterior Crico-arytenoid
Thyro-arytenoid
Lateral Crico-arytenoid
Cricothyroid

5
Identify the role played by each of these muscles
in the control of the control of the size of the
rima glottidis.

6
Follow the course of sensory and motor
innervation of the larynx. Predict the functional
consequences of damage to these nerves.
7
Trace the course of nerves through the neck
noting especially the sensory and motor branches
of the cervical and brachial plexuses, their
course and distribution in the neck and their
relationship to major bony, muscular, or vascular
landmarks in the region.
8
Trace the course of nerves through the neck
noting especially the extension of the upper
part of the sympathetic trunk into the neck
region.
9
Trace the flow of arterial blood from the aorta
through the neck including vessels that pass
through the neck without branching and those that
send branches to viscera and muscles of the neck.
Two main arteries are found in the neck
Subclavian and branches and Carotid
Ext. Carotid
10
Trace the pathways for venous drainage from the
neck into the brachial veins.
