reticular formation

Question 1

efferent long distance reticular fibers arise from

Answer 1

medial 2/3 of the reticular formation (RF). this is the paramedial reticular formation

Question 2

RF fibers that travel a short distance are mostly in

Answer 2

the lateral 1/3 of the RF. this is more related to circuits, interneurons

Question 3

how are the main dendritic branches of the RF oriented?

Answer 3

in a plane perpenduciular to the long axis of the brainstem

Question 4

what are some of the functions of the RFC

Answer 4

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

Question 5

parts of the reticular formation

Answer 5

raphe nuclei, paramedian reticular formation, periaquaductal gray, ventral tegmental area, locus coeruleus

Question 6

what type of chemical is recognized by raphe nuclei

Answer 6

serotonergic (5H)

Question 7

what nuclei in the thalamus does the RF project to

Answer 7

intralaminar nucleus
