Which is NOT found in the posterior triangle of the neck?
a.
Branches of the cervical plexus
F - found in the posterior triangle
b.
Occipital lymph nodes
T – Old Moore says that cervical and subclavian LN are in this triangle p1004
c.
Accessory nerve
F
d.
Cervical plexus
F – Adam says this is right
e.
Inferior belly of omohyoid
F
f.
Transcervical vessels
F – Blitz says this
g.
Branches of brachial plexus
T
30.
All the following are boundaries of the named triangle EXCEPT
a.
mandible and submental triangle
F - it is formed with anterior belly of digastrics, midline and hyoid bone
(or as per moore; unpaired therefore both anterior bellies of digastrics
with hyoid bone) p1065 NM
b.
mandible and anterior triangle
T - with midline and SCM
c.
mandible and digastric triangle (aka submandibular triangle) T - with ant and post bellies of digastric
d.
sternocleidomastoid and carotid triangle
T - with posterior belly of digastric and superior belly of omohyoid
e.
sternocleidomastoid and anterior triangle
T - with clavicle and Trapezius
31.
All the following are contents of the posterior triangle EXCEPT
a.
accessory nerve
T
b.
cervical plexus
T
c.
inferior belly of omohyoid
T
d.
transverse cervical vessels
T
e.
occipital lymph nodes
F - since they are def posterior the anterior border of trapezius p1058NM
(adam and blitz aren’t sure but they think the cervical plexus because the
actual plexus doesn’t sit in the posterior triangle but its branches do.)
So take your pick!
32.
Which of the following is NOT contained in the carotid triangle
Pg101,1014
a.
superior thyroid vein
F - probably is in the carotid triangle
b.
posterior auricular artery
T - branch of the external carotid A and origin is superior to posterior belly of
digastric m so NOT in the carotid triangle
c.
external laryngeal nerve
F - is in carotid triangle
d.
superior root ansa cervicalis
F - is in carotid triangle
e.
bifurcation common carotid artery
F - is in carotid triangle
Posterior triangle – occipital triangle and supraclavicular triangle
Anterior triangle – submandibular triangle, submental triangle, carotid triangle,
muscular triangle
33.
Question regarding the carotid sheath

c.

T
d.
Contains Internal carotid artery
T
e.
Contains internal jugular vein
T
f.
