Cervical Plexus Flashcards
The cervical plexus is made up of which nerve roots
C1-C4
the cervical plexus originates from the
Ventral (anterior) rami of C1-C4
The cervical plexus is found deep to which muscle
Sternocleidomastoid
The cervical plexus forms an anastomosis with (3)
CN XI, CN XII, and sympathetic trun k
Cranial nerve XII is also called
Hypoglossal nerve
What does the cervical plexus innervate
Posterior head and some neck muscles
the sympathetic trunk is part of which nervous system
Autonomic nervous System (Fight or flight
What are the cutaneous branches of the cervical plexus
Lesser occipital, Greater auricular, transverse cervical, and Supra Clavicular
The lesser occipital nerve is made up of which nerve segments
C2
The greater auricular nerve is made of which nerve segments
C2,C3
The transverse cervical Nerve is made of which nerve segment
C2,C3
The Supra Clavicular nerve is made of which nerve segments
C3, C4
Where is the cutaneous distribution of lesser occipital nerve
Skin of posteiror pinnacle of ear
Where is the cutaneous distribution of greater auricular nerve
Most of the skin over ear, parotid gland, mastoid process
Where is the transverse cervical nerve cutaneous distribution
Anterior neck
Supraclavicular nerve cutaneous distribution is found where
Skins of shoulder and upper pectoral
The vagus nerve is made of up of which segments and joins the
C1,C2 nerves and joins at inferior ganglion of vagus
Hypoglossal nerve is made up which nerve segments and leads to
C1,C2 and leads to the Ana’s cervical is
Ansa Cericalis is a
Loop of nerves that innervate a majority of the neck muscles
Sympathetic trunk receives
All gray rami communications from the superior cervical ganglion
what is the largest branch of T1 region nerves
T1, part of the brachial plexus.
Smallest is first intercostal nerve
T2 nerves are made up of
Intercostaobrachial nerve and second intercostal nerve
T3-T11 nerves make up
3rd-11th intercostal nerves
T12 subcostal nerve is found
Below the rib and inner sets intercostal muscles
Intercostal nerves 2-5 innervate
Serratus posterior superior (ribs 2-5)
Intercostal nerves 9-12 innervate
Serratus posterior inferior (ribs 9-12)
