The accessory nerve origin
upper 5 cervical segments
Where does it pass?
Through investing fascia in roof of posterior triangle
What does it supply?
motor fibres to SCM and trapezius
Sensory fibres derived from
Cervical nerve roots
Recurrent meningeal nerves
ventral rami - cervical and brachial plexuses
dorsal rami - supply structures posterior to transverse processes
Recurrent meingeal nerve
contains sensory and sympathetic fibres
supplies intra canal structures
i-V disc
What may pierce the scalenus medius?
Dorsal scapular nerve
Cervical plexus derived from?
anterior rami of C2-4
Sensory distrubution ?
skin of neck side of head via branchs of occipital C2, great auricular C2, 3, transverse cervical C2,3, supraclavicular C3,4.
Deep branches derived from?
Ventral rami of C1-3
Motor supply to strap muscles?
C1 fibres via the hypoglossal nerve to supply throhyoid
Cervical dorsal posterior rami supply?
capsule of facet joints, deep back muscles (erector spinae) that move the joint and the overlying skin
Posterior ramus C1
motor to intrinsic muscles of the back no sensory fibres
Posterior ramus C2
largest sensory nerve-supplies skin of back of neck as far as motor
Common carotid passes in carotid shealth to level?
Internal carotid
no branches in neck
Subclavin system
supplies upper limbs 1/2 of brain most of spinal cord
Main branch in neck
vertebral passes in triangle between longus colli and scalenus anterior
Vertebral artery
supplies spinal cord + 1/2 brain
1st part
subclavian artery to transverse foramen C6
