Question 1

sub thalamic nuclei

Answer 1

-controls and fine tunes movement
- influences basal ganglia structures

Question 2

epithalamus

Answer 2

regulates circadian rhythms
controls emotional responses
influences endocrine activity

Question 3

thalamus

Answer 3

RELAY STATION: processes and filters information to cerebral cortex
-regulation of arousal, consciousness, sleep

Question 4

hypothalamus

Answer 4

HOMEOSTATIC FUNCTION
- body temp
- metabolic rate
-BP
-fluid intake/output
-digestion

endocrine control
autonomic control
limbic system

Question 5

Answer 5

NOT NEURAL TISSUE

hormones:
-GH
-TSH
-ACTH
-LH
-FSH

Question 6

posterior pituitary

Answer 6

NEURAL TISSUE

hormones
-ADH
oxytocin

Question 7

relay nuclei

Answer 7

transmit motor/sensory info FROM basal ganglia, cerebellum, sensory systems TO cerebral cortex
- somatic sensation
-hearing
-vision

Question 8

association nuclei

Answer 8

process memory and emotional info
-limbic function
-sensory integration

Question 9

nonspecific nuclei

Answer 9

regulates consciousness, arousal attention
-limbic function
-arousal
-adjusts thalamic activity

Question 10

all thalamic nuclei project to the cerebral cortex except for…

Answer 10

thalamic reticular nucleus
-project to thalamic nuclei and reticular formation

Question 11

thalamic reticular nucleus

Answer 11

• a thin layer of neurons that wraps around the thalamus.
• It plays a crucial role in regulating sensory information before it reaches the cortex.
• contain GABA neurons: inhibitory function

Question 12

pusher syndrome

Answer 12

R brain lesion –> L impaired –> L shift
- shift to contralateral side (less affected side)
