Parts and Functions of the Brain Flashcards
1
Q
three major brain regions
A
hindbrain
midbrain
forebrain
2
Q
hindbrain
A
- rear base of the skull
- responsible for the basic biological needs for life
- vital functions (heart rate, breathing
3
Q
structures of the hindbrain
A
medulla
pons
cerebellum
4
Q
medulla
A
- controls breathing, heart rate, swallowing, and digestions
- where the spinal cord connects to the skull
5
Q
pons
A
- sleep and arousal (alertness/attention)
- connects cerebellum to the rest of the brain
6
Q
cerebellum
A
- regulates and coordinates body movements
- rear of the head and behind brain stem
- “little brain” that deals with learning
7
Q
midbrain
A
- above the hindbrain
- attention and stimulation
8
Q
reticular formation
A
- inside the midbrain
- regulation of maintenance of consciousness and sleep
- bundle of nerves
- filters incoming stimuli and relays important info to the brain
9
Q
forebrain
A
- most forward in skull
- controls complex emotions, thoughts, and movements
10
Q
structures in the forebrain
A
thalamus
hypothalamus
limbic
11
Q
thalamus
A
- brain’s sensory relay station
- sorts and sends messages from the eyes, ears, tongue, and skin to the brain (except smell)
- “inner chamber”
- top of brain stem
12
Q
hypothalamus
A
- regulates homeostasis
- below thalamus
- regulates eating, drinking, sexual behavior, motivation, emotion, and aggression
13
Q
two structures of the limbic system
A
amygdala
hippocampus
14
Q
amygdala
A
fear and aggression
15
Q
hippocampus
A
memory formation
