Topic 19: Nervous System - Hindbrain Functional Systems Flashcards
1
Q
What are the two functional systems of the hindbrain?
A
- limbic system
- reticular formation
2
Q
What structures does the limbic system contain? (2)
A
- nuclei in cerebral hemisphere
- diencephalon
3
Q
What does the limbic system regulate?
A
- emotion (laughing, crying, etc)
4
Q
What type of areas does the limbic system contain?
A
- areas involved in memory (memories evoke emotional responses)
5
Q
What structures does the reticular formation contain?
A
- nuclei in brain stem
6
Q
What other parts of the brain aid in reticular formation? (3)
A
- cortex
- thalamus
hypothalamus
7
Q
What is Reticular Activating System (RAS)?
A
the nuclei in brain staim, cortex, thalamus, hypothalamus
8
Q
What does reticular formation regulate?
A
- alertness and attention
9
Q
How does reticular formation regulate alertness and attention? (2)
A
- filters stimuli
- only sends new/unusual signals to other brain areas
10
Q
What happens when reticular formation is inhibited?
A
- sleep
11
Q
What happens if reticular formation is damaged?
A
coma
