Chapter 11 Efferent Division: Autonomic & Somatic Motor Control単語カード | Quizlet

parasympathetic nervous system

rest and digest

status quo

sympathetic nervous system

fight or flight

blood glucose levels

blood flow

both working together to maintain homeostasis

there are things only one can do

sweat glands - sympathetic only

vasoconstriction/vasodialation -sympathetic only

dynamic equilibrium of parasympathetic and sympathetic systems

hypothalamus

osmoreceptors, thermoreceptors, responses to hunger

medulla & phone

heart rate center, breathing center, blood pressure

limbic system & cerebral cortex

behavior responses

(endocrine responses, behavioral responses, some motor responses)

no brain integration. just spinal cord

spinal reflex integration

preganglionic - autonomic ganglion - postganglionic - target

efferent pathway

Vagus Nerve (x)

Which cranial nerve provides 75% of all parasympathetic outflow?

craniosacral

rest and digest

long PREgang & short POSTgang

PREgang: ACh

POSTgang: ACh

Parasympathetic Characteristics

thoracolumbar

fight or flight

short PREgang & long POSTgang

PREgang: ACh

POSTgang: NE and E

Sympathetic Characterists

epinephrine

What NT does the Adrenal Sympathetic Pathyway release?

Pre-post synapse:

nicotinic cholinergic receptors

Neuroeffector junction: muscarinic cholinergic

What is the receptor at the Pre-Post synapse for the parasympathetic/craniosacral divison?

At the neuroeffector junction?

Pre-post synapse:

nicotinic cholinergic receptor

Neuroeffector junction:

alpha or beta adrenergic receptor

What is the receptor at the Pre-Post synapse for the sympathetic/thoracolumbar division?

At the neuroeffector junction?

varicosities

a type of neuroeffector junctions

swellings along axons

there are multiple along the axon

produce NT

action can be modulated

B1 receptor

equal response to NE and E

-- effector cells innervated by sympathetic system

B2 receptor

stronger response to E (usually hormone)

--- effector cells not innervated by symp. system

--- responds to E from adrenal medulla (neurosecretory tissue - neurohormone)

B3 receptor

stronger response to NE

--- effector cells: adipose tissue

--- innervated by symp. system
