Autonomic control Flashcards
what can sympathetic nervous system cause?
↑ HR, BP, blood to skeletal muscle, metabolism/catabolism
↓ salivation/intestinal secretion, blood to skin, excretion
what can the parasympathetic system cause?
Remember SLUDD! (salivation, lacrimation, urination, digestion, defecation)
↑ salivation/intestinal secretion, lacrimation, excretion
↓ HR, BP, metabolism/catabolism
_________ is long in parasympathetic, and ______ is long in sympathetic
preganglionic
post-ganglionic
what is released from pre/post ganglionic in sympathetic vs parasympathetic?
Sympathetic:
-Pre: Ach
-Post: NE/epi
Parasympathetic
-Pre: Ach
-post: Ach
_________ cell in adrenal medulla releases Epi or NE
Chromaffin
All sympathetic to head has 2nd ganglion in ______________
superior sympathetic ganglia
what are B fibers like?
Lightly myelinated
Smaller, more peripheral
preganglionic
what are C fibers like?
Postganglionic
unmyelinated
________ horn receives somatic sensory
_________ horn iswhere preganglionic sympathetic cell bodies are
________ horn is where ventral horn motor neurons are
Dorsal
Lateral
Ventral
Which Cranial nerve, parasympathetic ganglion, and function is the Edinger Westphal nucleus known for?
CN: III
PS ganglion: Ciliary ganglion
Fxn: pupillary constriction
Which Cranial nerve, parasympathetic ganglion, and function is the Superior Salivatory nucleus known for?
CN: VII
PS ganglion: Submandibular ganglion
Fxn: submandibular/sublingual salivary glands
Which Cranial nerve, parasympathetic ganglion, and function is the Lacrimal nucleus known for?
CN: VII
PS ganglion: Pterygopalatine ganglion
Fxn: lacrimation
Which Cranial nerve, parasympathetic ganglion, and function is the Inferior salivatory nucleus known for?
CN: IX
PS ganglion: Otic ganglion
Fxn: parotid salivary gland
Which Cranial nerve and parasympathetic ganglion is the dorsal vagal nucleus known for?
CN: X
PS ganglion: ganglion in neck, thorax, abdomen
which CNS nucleus is the only one located above the pons?
Edinger-westphal
_________ system is a special division of ANS that does NOT need CNS connection to function
Enteric
what does the enteric system control?
motor functions, local blood flow, mucosal transport and secretions, and modulates immune and endocrine functions (ex: peristalsis)
What are these different parts of the brain responsible for feeling/sensing?
Hypothalamus
Cingulate cortex:
Insular cortex
Hippocampus:
Septal nn
Amygdala:
Nucleus accumbens
-Hypothalamus: hunger, thirst
-Cingulate cortex: feels emotion (3 layered)
-Insular cortex: emotion, taste, smell
-Hippocampus: memory, learning
-Septal nn: reward (can be stimulated with drugs)
-Amygdala: anger
-Nucleus accumbens: addiction
what is the pathway for all autonomic afferents?
- ALL General visceral afferent (GVA) comes into the CNS and synapses on nucleus of solitary tract (NTS)(on brainstem)
- message sent to limbic system structures
- limbic systems send opinion back down through NTS to Lower preganglionic brainstem and spinal cord nuclei
what are the different levels of control?
CNS, Local
what are some examples of local control?
Neurotransmitters with both sympathetic or parasympathetic aftion
what are some neurotransmitters with sympathetic actions?
Neuropeptide Y, ATP, serotonin
what are some neurotransmitters with parasympathetic actions?
Vasointestinal peptide, nitric oxide
what is another example of local control?
-Presynaptic autoreceptors: feedback inhibition of neurotransmitter release
