Question 1

peripheral

Answer 1

plexus: cervical, brachial, lumar, sacral. batch of nerves, ganglia: structure containing a number of nerve cell bodies, typically linked by synapses, and often forming a swelling on a nerve fiber
root: part of nerve intially leaving cns
Myelin is a lipid-rich (fatty) substance formed in the peripheral nervous system (PNS) by Schwann cells.
Myelin: insulating layer allowing for effiency.

Question 2

central NS component

Answer 2

tracts which are part of spine
afferent/acending is towards cns, efferent/descend is away
DCML also ascending
anterolaterla spinothalamic asending and pain, temp
brain and spinal chord
Myelin is a lipid-rich (fatty) substance formed in the central nervous system (CNS) by glial cells called oligodendrocytes,
nuceli: ganglia for CNS

taste, hearing, sight, smell (olfactory)

taste: bumps called papillae, facial and glossal nerves-medulla oblongta-thalmus-cortex gustaroy and parietal lobe
olfactory: sustenacular cells oxidzie hdrophobic odors, inter connections made with amygdyla, hippocamups and limpid sysstem thru pirifom cortex
hearing: balance is inner ear know utricle and saccule, modifiied epithelial cells sterocilia, and kinocilium (true cilium), tympanic membrane, cochlea, sensory hair cells on basilar membrane, vestibular choclear nerve,
vision: aqueus humor fills anteror adn posterior chambers, cones, pupillary reflex from gangin cells,

at rest is -70 high K inside adn NA outside. is polarized cuz inside is more negative.
