Cranial nerve V/Trigeminal nerve |
Class: motor Function: chewing Location: masseter, temporalis |
|
|
Cranial nerve VIII/ vestibulocochlear |
Class: sensory Function: hearing, equilibrium |
|
|
Cranial nerve X/vagus nerve |
Class: mixed Function: taste, monitors blood pressure, measures carbon dioxide and oxygen in blood, somatic senses such as touch, taste, & temp. Sensations from visceral organs in abdomen |
|
|
Cranial nerve XI/ accessory nerve Originates from both brain stem and spinal chord (the only cranial nerve that does this) |
Class: from cranial, Motor From spinal chord, mixed mainly motor Function movement of head and shoulders, swallowing |
|
|
Plexus Plexus |
Network of axons Made up of ventral or anterior rami NOT dorsal |
|
|
Cervical plexus Phrenic nerve |
Found deep w/in nneck Innervates diaphram, stimulates breathing Made up of ventral rami of cervicalnerves of c-1 through |
|
|
Lumbar plexus |
●Formed by lumbar spinal nerves L-1 through L-4 ●Network located psoas major ●splits into 2 main nerves that innervate lower limbs |
|
|
Femoral nerve (largest nerve) |
●Off of L-3 & L-4 ●responsible all the way to toe ●mixed skin-sensory Muscle is motor ● innervates skin & muscle of anterior thigh |
|
|
Obturator nerve |
●Class- mixed *skin is sensory *muscle is motor ●function- innervates skin and muscle of medial thigh
|
|
|
Erector spinae Named for Location Function |
Function and location Medial to lateral- S, L, I ●spinalis- close to the spine ●longisimus- on both sides of Spine (longest of the 3 ●iliocastalis- connects to ilium. and ribs (costal) Function- keep spine erect |
|
|
Erector spinalis- divided and named by row of vertebrae |
●inferior - lumborium ● middle - thoracic ● superior - cervicus (neck) Capitas (skull) |
|
|
Spinalis thoracis |
●Origin/inferior- spinous process of the upper lumbar and lower thoracic vertebrae ●insertion/superior - spinous process of upper thoracic vertebrae |
|
|
Spinalis cervicus*when present |
●inferior origin -Nuchal ligament, spinous process of c-7 ●superior insertion - spinous process of of cervical vertebrae except c-1 |
|
|
Longisimus thoracis |
●inferior origin - transverse process of lumbar vertebrae via the common tendon ●superior insertion - transverse process of of thoracic vertebrae |
|
|
Longisimus cervicus |
● inferior origin - transverse process of thoracic vertebrae ● superior insertion - cervical vertebrae, mastoid process of temporal bone |
|
|
Action of all erector spinae |
Bilateral - extension of spine Unilateral - lateral flexion of spine (side bending) |
