ANS lecture (no CC) Flashcards
PVN projects to?
Post/ant pituitary
Locus coeruleus
Parabrahcial nuclei
Locus Ceruleus fx
Norepinephrine. Related to arousal and consciousness (with regards to sleep)
parabrachial nucleus
related to respiratory rhythm. Inputs from nucleus solitarius (visceral). part of central autonomic network.
gets nociceptive, visceral and thermoreceptive stimuli.
amygdala
fear and anxiety–> hypothalamus –> CNS changes
PAG
freezing response to pain
integration of autonomic response to stressors.
Anterior cingulat cortex
part of limbic system. Modulates arousal via ANS.
Goal directed behaviors
Insular cortex
Input from viscerosensory.
Visceral pain
to primary viscerosensory cortex in insular cortex==>lateral hypothalamus
Reticular formation in medulla (whats another name? Fx?
ventrolateral medulla
GVA activate it to change BP and respiration
maintenance of reflex arterial BP
Medullary raphe
responses to cold and emotional stimuli
Neuropeptide Y
Hypothalamus senses NPY in arcuate neurons. When HIGH NPY= FEEDING BEHAVIOR stimulation
Fornix
LARGEST projection to hypothalamus. Connects hippocampus to anterior nucleus of hypothalamus, septal nucleus, and mammillary bodies.
