Lesion of the visual pathway
Give this one a try later!
- causes blindness
Cauda Equina: horse tail
Give this one a try later!
- spinal cord ends at about L2, so spinal nerves from lower levels of cord
extend downward through vertebral canal a ways before exiting through
vertebral foramina
,Sensory receptor for myotatic reflex
Give this one a try later!
- muscle spindle apparatus
- contains stretch-sensitive neuron terminals wrapped around intramural
muscle fibers
- activated when muscle spindle is lengthened
- provides CNS with moment-to-moment feedback regarding changes in
muscle length
The shortcut of fluid movement
Give this one a try later!
- scala vestibuli fluid movement against vestibular membrane displaces
fluid inside scala media
- causes displacement of the basilar membrane
M1, M3, or M5
Give this one a try later!
- M3 found on autonomic target tissues
- ACh
- muscarine
- Gq protein
,Visceral afferent neurons (VAN)
Give this one a try later!
- innervate the internal organs
Tonotopy
Give this one a try later!
pitch/frequency 'map' on a structure
Convergence
Give this one a try later!
- many descending axons make synaptic contact on each motor neuron
(directly and through interneurons)
Nociceptor AP firing
Give this one a try later!
- stimulus energy causes cation channels in bare nerve ending to open
- entry of Na+ depolarizes nerve ending
- if strong enough, V-gated Na+ channels are depolarized to threshold to
trigger an AP
, - as long as depolarization of nerve ending persists AP will continue to be
formed
Photopigments
Give this one a try later!
- two components:
1) opsin
2) retinal
Upward basilar membrane movement causes
Give this one a try later!
1) stereocilia bend toward tallest, opens m-gated K+ channels
2) endolymph K+ moves into hair cells
3) K+ influx = depolarization
4) opens voltage-gated Ca++ channels to increase release of vesicles with
NT
- can promote AP in postsynaptic neuron
Disc membranes
Give this one a try later!
- contain most proteins needed for phototransduction
- light absorbing photopigments that act like a GPCR
