Week 7 biological psychology

Question 1

medulla (Hindbrain)

Answer 1

-maintains breathing, blood circulation

Question 2

pons (Hindbrain)

Answer 2

-relays movement, regulates breathing, taste and sleep

Question 3

cerebellum (Hindbrain)

Answer 3

-motor coordination, precision, accurate timing

Question 4

tegmentum (Midbrain)

Answer 4

nuclei connected to motor control

Question 5

tectum (Midbrain)

Answer 5

controls and relays sensor information

Question 6

Thalamus (Forebrain)

Answer 6

sensory relay to cerebral cortex

Question 7

Hypothalamus (Forebrain)

Answer 7

maintains internal environment of the body

Question 8

cerebral cortex

Answer 8

-outer surface of the brain
-subdivided into lobes
-frontal, parietal, occipital, temporal
-gyrus = each bump/convolution
-sulcus = each valley between bumps

Question 9

frontal lobe function

Answer 9

• high level thoughts
• planning and functioning
• contains motor regions concerned with planning and execution of movement
