Brain Structures Flashcards
1
Q
Cerebrum
A
CN 1 and 2
2
Q
Midbrain (3)
A
- connects diencephalon with the pons
- contains aqueducts
- CN 3 and 4
3
Q
Pons (4)
A
- motor control and sensory analysis
- respiration
- CN 5-8
- lower pons - decussat
4
Q
Medulla (4)
A
- HR, respiration, vasoconstriction, and vasodilation
- controls head and eye movements
- coordinates swallowing
- CN 9-12
5
Q
Cerebellum (2)
A
- balance and coordination
- motor planning
6
Q
Reticular Formation (3)
A
- integrates sensory and cortical info
- effects the level of excitability for motor neurons
- sends info to the cerebral cortex without synapsing at the thalamus
7
Q
Semicircular Canals
A
detects rotational acceleration
8
Q
Otolithic Organs
A
detect linear acceleration and deceleration
9
Q
Thalamus (3)
A
- selective filter for the cerebral cortex
- association nuclei - process emotion and some memory info, integrate
- nonspecific nuclei - regulates consciousness, arousal, and attention
10
Q
Epithalamus (2)
A
- contains pineal gland
- regulates circadian rhythms
11
Q
Hypothalamus (3)
A
- maintains homeostasis
- eating, reproductive, and defensive behaviors
- emotional expression
12
Q
Subthalamus (2)
A
- regulates movement
- facilitates basal ganglia output
13
Q
Broca’s Area (2)
A
- speech production [motor planning]
- frontal lobe
14
Q
Wernicke’s Area (2)
A
- language comprehension
- temporal lobe
15
Q
Sympathetic nervous system (ANS)
A
- maintain optimal blood supply to the organs
- vasoconstriction and vasodilation
- “fight-or-flight” response
