areas of the brain - L6

Question 1

hindbrain

Answer 1

found at the base of the brain
consists of the medulla, pons and cerebellum

Question 2

midbrain

Answer 2

located deep within the brain

collection of structures involved with movement, processing of sensory information and sleep and arousal

Question 3

forebrain

Answer 3

controls and regulates higher order functions

personality
cognitive functions
learning
perception

Question 4

medulla (medualla oblongata)

Answer 4

controls reflexive functions vital for survival

damage: loss of consciousness/ death

Question 5

pons

Answer 5

involved in sleep, dreaming and arousal

relay/bridge function from cerebrum to cerebellum

damage: locked in syndrome - brain is active however body is paralysed

Question 6

cerebellum

Answer 6

coordination of fine muscle movement (ensures movement is smooth and precise)

controls which muscles are activated when performing an action, and the extent to which they are used

regulates posture and balance

Question 7

reticular formation

Answer 7

filters incoming sensory information so the brain is not overloaded

maintains consciousness

regulates arousal and muscle tension

Question 8

hypothalamus

Answer 8

maintains the body’s internal environment (homeostasis)

-body temperature
- regulates emotions
- hunger
- thirst
- sexual functioning
- regulates hormone release

Question 9

thalamus

Answer 9

filters and transfers all sensory information (except smell) to relevant parts of the brain for processing

transfers neural information (concerning alertness and attention) from the reticular formation to the cerebral cortex

damage:
-loss of any sense (except small)
- attention difficulties
-lower arousal

Question 10

reticular activating system

Answer 10

involved in arousal

involved in attention especially selective attention. it initiates the attention response by rapidly alerting cortical areas of the brain to significant changes in the environment
