arousal and attention

18
Q

reticular function

A

adjusts thalamic nuclei

19
Q

what is most affected in thalamic lesions

A

proprioception

20
Q

lateropulsion

A

Lesion of posterior thalamus or vestibular nuclei

21
Q

what happens with a lesion of the posterior thalamus

A

spatial inattention to postural alignment

22
Q

hypothalamus fuction

A

integrates behaviors and visceral functions. maintains homeostasis

23
Q

thyrotropin releasing hormone

A

increases secretion of thyroid

24
Q

somatostatin

A

inhibits growth

25
corticotropin releasing hormone
increases glucocorticoid secretion from adrenal cortex
26
gonadotropin releasing hormone
ovulation and progesterone production, testosterone synthesis, follicle maturation and estrogen secretion, sperm production
27
prolactin releasing hormone
milk production
28
prolactin inhibiting hormone
inhibits secretion of prolactin
29
vasopressin
antidiuretic hormone maintains osmality and volume of extracellular fluid
30
oxytocin
stimulates smooth muscle in uterus and elicits milk expulsion
31
what do pituitary tumors cause
headaches, nausea and vomiting, irregular menses and lactation, sexual dysfunction, high BP, high BG, acromegaly, Cushing's disease, double vision, hemianopia
32
epithalamus function
regulates circadian rhythms -Influences secretions of pituitary, adrenals, parathyroids, and islets of Langerhans
33
subthalamus
regulates movement facilitates basil ganglia output
