Limbic System and Hypothalamus Flashcards
the Hypothalamus is responsible for what level of processing?
homeostasis
The limbic system is responsible for what order of processing?
social homeostasis (basic survival level)
the hypothalamus is derived from what embryological origin?
diencephalon
output from the hypothalamus is mediated via what gland?
pituitary gland and the limbic system
where is the hypothalamus on this picture? how about the pituitary gland?
what are the functions of the hypothalamus?
- fluid/electrolyte balance
- food ingestion
- thermoregulation
- reproduction
- immune responses
- circadian rhythms
*
what are the different type of inputs into the hypothalamus?
blood (chemical, temp osmolality)
neural (nucleus solitarius- chemoreceptors)(reticular formation - diffuse set of information pertaining to the state of arousal)
from what embryological remnant does the limbic system develop?
from the border bewteen the diencephalon and the telencephalon
