25
What is the carotid triangle?
subdivision of the anterior triangle borders: SCM, posterior belly of digastric, omohyoid common carotid bifurcates within triangle
26
What are the borders of the posterior triangle of the neck?
trapezius, clavicle, SCM
27
Attachments of SCM muscle?
origin: manubrium (sternal head), clavicle (clavicular head) insertion: mastoid process
28
Action of SCM muscle?
unilateral: ipsilateral flexion of neck, contralateral rotation of head bilateral: flex neck
29
What innervates SCM?
accessory n. (CN XI)
30
What are the muscles within the posterior triangle of the neck?
inferior belly of omohyoid, scalenes (anterior, middle, posterior), levator scapulae, and splenius capitis
31
Action rule of the scalenes? Innervation?
laterally flex neck or elevate ribs cervical plexus
32
Spinal levels of cervical plexus?
ventral rami C1-C4
33
Cutaneous branches (sensory) of cervical plexus
emerge from posterior edge of SCM "nerve point of the neck"
34
Why is the nerve point of the neck clinically relevant?
point for injection of anesthetic when performing neck procedures
35
Ansa cervicalis
loop formed by C1-C3, motor branch located SF to carotid sheath
36
What does ansa cervicalis innervate?
most infrahyoid muscles some fibers "hitchhike" with hypoglossal n. (CN XII) making it look like they are branches of CN XII, they are NOt
37
Spinal levels of phrenic nerve?
C3-C5
38
Where does the phrenic nerve travel?
SF to anterior scalene to targets in thorax
39
What are the nerves in the SF neck?
cervical plexus (ansa cervicalis, phrenic nerves) glossopharyngeal (CN IX) accessory n. (CN XI) brachial plexus (roots btwn anterior and middle scalene muscles and trunks located in posterior triangle
40
What is the right common carotid a. a branch off of? left common carotid a.?
brachiocephalic trunk arch of aorta courses superiorly within the carotid sheath
41
What do the common carotid aa. give off?
internal carotid a. and external carotid a.
42
What is the carotid body?
located at the bifurcation of the common carotid, chemoreceptors that monitor blood gas levels
43
What is the carotid sinus?
enlargement of internal carotid artery near its point of bifurcation, contains baroreceptors that monitor BP
44
What innervates the carotid body and sinus?
glossopharyngeal n. (CN IX)
45
What can occur with carotid sinus massage?
activates glossopharyngeal n. endings slow heart rate via vagus nerve- should nerve be performed bilaterally
46
Internal carotid aa.
course superiorly within carotid sheath no branches in neck, supplies intracranial structures
47
external carotid a.
supplies neck, scalp, face and part of orbit many branches in neck
48
What are the major branches of the external carotid aa.
occipital a. facial a. lingual a. ascending pharyngeal a. superior thyroid a.
49
What are the branches of the subclavian arteries in the neck?
internal thoracic artery vertebral artery thyrocervical trunk
50
Where do the vertebral arteries travel?
through the transverse foramina of the upper 6 cervical vertebrae
51
What are the branches of the thyrocervical trunk in the neck?
transverse cervical suprascapular
52
What are the veins in the neck?
external jugular veins internal jugular veins subclavian veins
53
Where are the external jugular veins located? Where do they receive blood from?
SF to SCM scalp, face, neck and shoulder drain into subclavian veins
54
Where are the internal jugular veins located?
course inferiorly within the carotid sheath
55
What do the internal jugular veins drain? What do they empty into?
structures within the cranial cavity join subclavian veins at venous angle
56
Where are the subclavian veins located?
course btwn clavicle and 1st rib, anterior to anterior scalene muscle
57
What do the subclavian veins drain?
blood from UE, head and neck
58
Where is a central line placed?
subclavian vein catheter can readily be introduced into the subclavian vein as it courses just inferior to the clavicle for administration of meds/fluids
59
Where does lymph from SF tissues of the neck drain into?
SF cervical lymph nodes along the external jugular vein > deep cervical nodes (along internal jugular v.) > right lymphatic duct or thoracic duct
60
Where does lymph from face/scalp drain into?
SF ring nodes >deep cervical nodes (along internal jugular v.) > right lymphatic duct or thoracic duct
