reticular formation Flashcards
1
Q
efferent long distance reticular fibers arise from
A
medial 2/3 of the reticular formation (RF). this is the paramedial reticular formation
2
Q
RF fibers that travel a short distance are mostly in
A
the lateral 1/3 of the RF. this is more related to circuits, interneurons
3
Q
how are the main dendritic branches of the RF oriented?
A
in a plane perpenduciular to the long axis of the brainstem
4
Q
what are some of the functions of the RFC
A
patterns (chewing, coughing), respiratory control, cardio control, sleep and levels of consiousness, pain modulation at the spinal cord, adjusting the motor system for posture and balance, ANS regulation, emotional regulation
5
Q
parts of the reticular formation
A
raphe nuclei, paramedian reticular formation, periaquaductal gray, ventral tegmental area, locus coeruleus
6
Q
what type of chemical is recognized by raphe nuclei
A
serotonergic (5H)
7
Q
what nuclei in the thalamus does the RF project to
A
intralaminar nucleus
