25
Funtions of frontal lobe
cognition motor spoken language
26
Parietal lobe
body sense
27
Occipital lobe
visual information
28
Temporal lobe
auditory information
29
Where is Wernicke’s area?
Temporal lobe
30
Where is Broca’s area?
Frontal lobe
31
Functions of Broca’s area
Language expression
32
Functions of Wernicke’s area
Language comprehension
33
Insular lobe
Planning & organization of speech
34
Subcortical structure
Thalamus Subthalamus Hippocampus Basal ganglia
35
Thalamus
Relay station for sensory info
36
Subthalamus
works with basal ganglia for motor control
37
Hippocampus
short or long term memory consolidation
38
Basal Ganglia
muscle tone, control & motor learning
39
3 structures of Brainstem
Midbrain Pons Medulla oblongata
40
Midbrain
houses cranial nerve nuclei
41
Pons
houses cranial nerve nuclei | a communication bridge
42
Medulla oblongata
houses cranial nerve nuclei
43
Main function of the brainstem
controls the flow of messages to and from the brain and the body
44
The cerebellum
integrates sensory inputs > motor activity contributes to precision, coordination and timing of movements
45
PNS stands for
Peripheral nervous system
46
2 types of nerves in PNS
Cranial nerves | Spinal nerves
47
Where are the cranial nerves?
Head and neck
48
Where are spinal nerves?
the rest of the body | “Spinal cord”
49
Main function of PNS
communicate sensory & motor information
50
Sensory pathways
Afferent pathways
51
Motor pathways
Efferent pathways
52
Afferent pathways
Arrive (received by the brain)
53
Efferent pathways
(Exit)
54
How many pairs of cranial nerves are there?
12 pairs of cranial nerves
55
Function of neurons
transmit information
56
Glial cells (function)
support neuron function
