Brain parts and functions Flashcards
1
Q
brainstem
A
- connects cerebrum and spinal cord
- controls life supporting functions
2
Q
medulla
A
- base of the brainstem
- controls unconscious behaviors (breathing, heartbeat)
3
Q
Pons
A
- above the medulla
- coordinates movement
4
Q
reticular formation
A
- nerve networks strung thru thalamus & brainstem
- arousal (sleep,walk,pain tolerance) & consciousness
5
Q
Thalamus
A
- on top of brainstem
- relays sensory & motor signals to cerebral cortex
6
Q
cerebellum
A
- rear of the brainstem
- coordinates voluntary movements (balance, speech)
7
Q
limbic system
A
- surrounds the thalamus
- hippocampus, amygdala, hypothalamus
- memory, emotion, regulating life supporting functions
8
Q
hippocampus
A
- ring around the thalamus
- learning and memory
9
Q
amygdala
A
- lima bean sized clusters at ends of hippocampus
- ability to feel motion & perceive it to others
10
Q
hypothalamus
A
- below the thalamus
- regulates body temp, heartbeat, hunger
- governs endocrine system
11
Q
cerebrum & cerebral cortex
A
- cerebrum is the 4 lobes
- cerebral cortex is thin layer of 20bill neurons covering the cerebrum
- plays role in consciousness , attention, thought, etc.
12
Q
corpus callosum
A
- middle line of brain, connecting 2 hemispheres
- transports messages received from one side to the other
13
Q
Frontal Lobe
A
- front of the cerebrum
- speaking, judgement, personality, concentration
14
Q
motor cortex
A
- rear of frontal lobe
- sends messages to body to perform actions
15
Q
parietal lobe
A
- middle of cerebrum
- sense of touch/pain
- spacial awareness
- concept of time
