Q

Spinal Chord

A

Colomn of neurons, controlls reflexes

17
Q

Three parts of the Brain

A

Hindbrain, Midbrain, Forbrain

18
Q

Hindbrain

A

medulla, controls heartrate and breathing

cerebellum, balance and coordination, learning and memory

19
Q

Midbrain

A

retucular formation, controls level of conciousness, attention and sleep.

20
Q

Forebrain

A

left hemisphere and right hemispheres.

21
Q

Cerebral Cortex

A

Outer layer of the forbrain,

gray matter, folds

22
Q

Frontal Lobe

A

Motor cortex

Voluntary movement

23
Q

pariatle lobe

A

touch temperature, pain, pressure

24
Q

temporal lobe

A

primary auditory cortex

25
occipital lobe
primary visual cortex, light and vision
26
Broca's Aphasia
left frontal, expressive but non fluent
27
Wernick's Aphasia
left temporal, receptive fluent no language comprehension.
28
Lateralization Function
When one hemisphere has more control than another in an action. Language is more from the left
29
Split brain patients
Hemispheres operate independantly of each other.
