Answer 9

sensory (touch, temperature, pressure and
pain) and spacial information processing

Question 10

Answer 10

fight or flight

Question 11

what is Autonomic imbalance

Answer 11

a hyperactive sympathetic system and a hypoactive
parasympathetic system,

Question 12

what is in grey matter

Answer 12

neuronal cell bodies and their dendrites.

Question 13

what cranial nerves are in the pons

Answer 13

vestibulocochlear, facial, trigeminal, abducens

Question 14

what is the primary visual coretx

Answer 14

receives visual information from the eyes. This information is relayed to several secondary visual processing areas, which interpret depth, distance, location and the identity of seen objects.

Question 15

what is the autonomic nervous system

Answer 15

mediates unconscious activities.
consists of nerves that connect the CNS to
the visceral organs

Question 16

what is the role of the pons

Answer 16

coordination centre for signals and communications that flow between the two brain hemispheres and
the spinal cord.

Question 17

what is the function of grey matter

Answer 17

Provides ability to think and reason.
Processing of sensation, perception, voluntary movement, learning, speech and cognition

Question 18

what is the somatic nervous system

Answer 18

consists of nerves that go to the skin and
muscles
mediates conscious/voluntary activities.

Question 19

what separates the frontal and temporal lobes

Answer 19

lateral sulcus

Question 20

what is the function of the frontal lobe

Answer 20

decision making
voluntary movements
brochas area

Question 21

what separates the frontal and temporal lobes

Answer 21

lateral sulcus

Question 22

what type of nerve only has afferent fibres

Answer 22

sensory

Question 23

what is the function of white matter

Answer 23

Provides communication between different grey matter areas and between grey matter and the rest of
your body.

Question 24

what are the two cerebral hemispheres connected by

Answer 24

the corpus callosum

Question 25

what is the function of the temporal lobe

Answer 25

memory processing hearing (contains the primary auditory cortex) recognising language wernike's area

Question 26

what is the function of the occipital lobe

Answer 26

vision

Question 27

what is the role of the cerebellum

Answer 27

most voluntary movements processes nerve impulses from the inner ear (balance and posture)

Question 28

what is the role of the medulla oblongata

Answer 28

transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration

Question 29

what cranial nerves are found in the medulla oblongata

Answer 29

glossopharyngeal, vagus, accessory, hypoglossal

Question 30

describe the activation of the sympathetic system

Answer 30

1. Upon stimulus/threat/stress > rush of adrenaline and noradrenaline secreted from the adrenal medulla causes almost all portions of the sympathetic system to discharge simultaneously 2. . ↑ arterial pressure ↑ blood flow to active muscles and ↓ blood flow to organs not needed. ↑ rates of cellular metabolism throughout body, ↑ muscle strength, ↑ mental activity, ↑ blood glucose concentration, ↑ glycolysis in the liver/muscle.

Question 31

what part of the temporal lobe is important for memory, learning and emotions.

Answer 31

hippocampus

Question 32

what is in the hindbrain

Answer 32

brainstem, pons, medulla oblongata and the cerebellum 12 cranial nerves

Question 33

spinal nerves are what type of nerve

Answer 33

mixed
