Triangles Questions with Complete Solutions
The ansa cervicalis travels with the ______________ nerve for a short distance while it's behind
the tongue hypoglossal
What forms the loop which makes the ansa cervicalis its superior and inferior roots
The loop of the ansa cervicalis lies (deep/superficial) to the internal jugular vein
superficial
The ansa cervicalis is what *type* of innervation to the infrahyoid muscles? (minus the
thyrohyoid which is innervated by the hypoglossal n.) motor
This is a *posterior* cervical triangle structure formed by anterior primary rami of C1-C4
has 2 divisions cervical plexus
What are the two divisions of the cervical plexus cutaneous and muscular
,The cutaneous division of the cervical plexus is responsible for innervating skin of the _______
and ________, it may have visible branches emerging underneath the posterior border of the
sternocleidomastoid m head, neck
both divisions of the cervical plexus form withing the _________ of the posterior triangle
floor
What nerves are part of the cutaneous branches of the cervical plexus lesser occipital n
great auricular n
transverse cervical n
supraclavicular n
The lesser occipital n, great auricular n, transverse cervical n, and supraclavicular n make up
what branch of what plexus? How far down do they innervate on the body? cutaneous
branch of cervical plexus, shoulder
What nerve is part of the muscular branch of the cervical plexus phrenic n
, This nerve of the cervical plexus comes from spinal segment C3-C5, it is *critical for breathing*
because it is the *sole motor* innervation to the diaphragm
also provides sensory to diaphragm, as well as innervation to the pericardial and mediastinal
structures phrenic n
what nerve provides sensory innervation and is the sole motor innervation to the diaphragm
phrenic n
ganglion = bulge containing nerve cell bodies
the ________ cervical ganglion occur at the level of C1-C2, *sends branches to the pharyngeal
region and heart* superior
branches sent from the superior cervical ganglion to the heart are called what; what about from
middle cervical ganglion? inferior cervical ganglion? superior cardiac n, middle cardiac n,
inferior cardiac n
The _______ cervical ganglion occur at the level of C6; branches go to the heart middle
