Lecture 11 Flashcards
fn of reticular formation
integrative fn’s (i.e. cardiovascular or respiratory regulation)
corticospinal pathway goes to
midbrain- cerebral peduncles
medulla- pyramids
pons- basal pons
corticobulbar pathways goes to
sympathetic pathway- lateral BS
which are the ascending tracts
anterolateral
dc/ml
FN of rostral RF
maintain alert conscious state of forebrain
FN of caudal RF
motor, relfex, and autonomic fns
rostral RF works with
upper pons, mesencephalon, diencephalic nuclei
caudal RF works with
pons, medulla, CN nuclei, spinal cord
4 diffuse modulatory systems
1) noradrenergic
2) seratonergic
3) cholingerc
4) domaminergic
which modulatory systems are involved in regulating wakefulness, alterness, and consciousness
noradrenergic
sertonergic
cholingergic
which modulatory system(s) are involved in regulation and initiation of movements and reinforcing behaviors
dopaminergic
fn of solitary nucleus
primary central sensory nucleus of autonomic system
caudal division of solitary nucleus FN
visceral sensory info
rostral division of solitary nucleus FN
gustatory sensation
somatic NS controls?
skeletal muscle
SNS uses ___ NT in preganglion
Ach
SNS uses ___ NT in postganglion
NE
PNS uses ___ NT in preganglion
Ach
PNS uses ___ NT in postganglion
Ach
(sns or pns) has longer pre-ganglion neuron
pns
(sns or pns) has longer post-ganglion neuron
sns
(sns or pns) has shorter pre-ganglion neuron
sns
(sns or pns) has shorter post-ganglion neuron
pns
6 FNs of hypothalamus
- regulate temperature
- daily rhythms
- emotions
- sex + reproduction
- food and H2O
- controls release of 8 major hormons by pituitary gland
magnocellular neurons project to?
post pituitary gland
mangnocellular neurons associated with which NT?
oxytocin
ADH
parvocellular neurons release their hormones into the?
hypothalamo-pituitary gland
