Block 1 Lecture 2 Flashcards
muscle between SP
interspinalis
unilateral action of intertransversarius muscle
lateral flexion
action of interspinalis muscle
back extension
suboccipital triangle bilateral action
extend head
muscle sensing force and limb position
proprioception
shortest transversospinal muscle
rotatores
transversospinal that runs 3-5 segments TP to SP
multifidus
transversospinal that is the longest and usually in the neck or head area going from TP to SP
semispinalis muscle
erector spinae muscles from lateral to medial
iliocostalis, longissimus, spinalis
unilateral action of transversospinal
rotate back
unilateral action of erector spinae
lateral flexion
splenius goes from blank to blank
SP to TP
splenius bilateral action is blank but unilateral action is blank
extend neck/head, rotate neck/head
muscles that move vertebral column
intrinsic back muscles
muscles that move upper limbs or ribs
extrinsic back muscles
thoracolumbar fascia is different from the blank
lumbar aponeurosis
intrinsic muscles of back innervation
dorsal rami of spinal nerves
besides innervating intrinsic back muscles, posterior primary rami innervate
cutaneous sensory of back
anterior primary ramus innervates
anterior/lateral cutaneous
cervical spinal nerves are blank to its corresponding vertebra
superior
thoracic and lumbar spinal nerves are blank to corresponding vertebrae
inferior
root for sensory
dorsal
root for motor
ventral
outer layer of spinal cord
dura mater
mater right on inner surface of dura mater
arachnoid mater
mater right up against spinal cord and brain
pia mater
a spinal tap takes fluid from between these maters at this level
arachnoid, pia, L3/L4
epidural is given outside this mater
dura
muscles between TP
intertransversarius muscles
