neurobiology

Question 1

What are the three regions of the brain

Answer 1

• hindbrain
• midbrain
• forebrain

Question 2

What are the two regions in the hind brain

Answer 2

• medulla oblongata
• cerebellum

Question 3

What are the six regions in the forebrain

Answer 3

• limbic system
• hypothalmus
• thalamus
• hyptoahlamus and thalamus
• cerebrum
• hippocampus

Question 4

What is the function of the medulla oblongata

Answer 4

involved with the control of heart rate, ventilation and blood pressure and contains many important centres of the autonomic nervous systems

Question 5

What is the function of the cerebellum

Answer 5

involved with the maintenance of posture and coordination of voluntary muscular movement

Question 6

What is the funciton of the midbrain

Answer 6

contains the nerve fibres that link the forebrain to the hindbrain

Question 7

What is the role of the limbic system

Answer 7

involved in emotion, learning and memory

Question 8

What is the role of the hypothalmus

Answer 8

involved in regulating body temperature, blood solute concentration, thirst, hunger and sleep, it is the main controlling region of the autonomic nervous system and provides a link between the brain and the endocrine system via the pituitary gland

Question 9

What is the role of the thalamus

Answer 9

important relay centre, sending and recieving information to and from the cerebral cortex

Question 10

what is the role of the hypothalmus and thalamus

Answer 10

interconnect with different areas of the brain including hippocampus

Question 11

What is the role of the cerebrum

Answer 11

controls the body’s voluntary behaviour , learning, reasoning , personality and memory

Question 12

what is the role of hippocampus

Answer 12

interacts with other areas of the cortex.is involved in learning, reasoning and personality and also consolidates memories into a permanent store

Question 13

What are the four structural regions of the cerebral hemisphere

Answer 13

• frontal lobe
• temporal lobe
• parietal lobe
• occipital lobe

Question 14

What is the function of the frontal lobe

Answer 14

reasoning, personality, planning, part of speech (Broca) and movement (the motor cortex), emotions and problem solving

Question 15

What is the function of the temporal lobe

Answer 15

language (Wernicke), auditory, learning, face processing and memory

Question 16

What is the function of the parietal lobe

Answer 16

somatosensory functions, visuo spatial processing and taste

Question 17

What is the function of the occipital lobe

Answer 17

visual cortex

Question 18

What are the subdivisions of the cerebral cortex

Answer 18

• sensory areas
• motor areas
• associaiton area

Question 19

What is the role of sensory areas

Answer 19

recieve nerve impulses from receptors in the body

Question 20

What are the functions of the motor areas

Answer 20

send nerve impulses to appropriate effectors via motor neurones

Question 21

What are the functions of association areas

Answer 21

makes up most of the cerebral cortex and recieve impulses from sensory areas and associates this information with previously stored informaition (from memory) which allows the information to be interpreted and given meaning, It is also responsible for intitiating appropriate responses which are passed to the relevant motor areas
