hypothalamus and ANS Flashcards
a single structure found behind the eyes, divided into several distinct nuclei
hypothalamus
a collection of cell bodies of a nerve cell in the CNS
nucleus
collections of neuronal cell bodies in the CNS
nuclei
a collection of neuronal cell bodies in the PNS
ganglion
collections of neuronal cell bodies in the PNS
ganglia
major function of the hypothalamus. includes monitoring of blood glucose levels, water content, regulation of appetite, sleep, sexual behaviour, body temperature
maintaining homeostasis
via what structure does the hypothalamus link the nervous system to the endocrine system
pituitary gland
how does the hypothalamus affect the pituitary gland
controls the release of hormones
section of the hypothalamus involved in the regulation of daily rhythms of the body
suprachiasmatic nucleus
the daily rhythms of the body
circadian rhythms
small endocrine gland in the brain. produces melatonin
pineal gland
a pea-sized gland that is housed within a bony structure at the base of the brain
pituitary
name for the hypothalamus, pituitary, and adrenal cortex alliance
HPA axis
section of adrenal glands that produce cortisol and aldosterone
adrenal cortex
section of adrenal glands that produces adrenaline
adrenal medulla
when does the HPA stimulate the immune response and immunological memory
acute, short-term stress
what nervous system is AKA the visceral nervous system
autonomic nervous system
what system works with the ANS to control the secretion of hormones, controlled by the hypothalamus
endocrine system
nerve cell bodies in the brain stem and sacral region of the spinal cord
PANS nerve cell bodies
What nerve carries most of the PANS signals
CN10 (vagus nerve)
which ganglionic fibres are long
preganglionic
which ganglionic fibres are short
postganglionic
where does all sympathetic nervous system outflow move through
T1-L2 cell bodies in the lateral horn
aka for solar plexus
celiac ganglion
