Question 1

Cerebrum

Answer 1

• Seat of higher level thinking and problem solving

Question 2

Cerebral Cortex

Answer 2

• Outer most part of cerebrum; composed of grey matter
• Folded to increase surface area
• Right and left cerebral cortex (left side of brain controls right side of body and vice versa)

Question 3

Cerebral Hemisphere

Answer 3

• Four lobes

Question 4

Frontal Lobe

Answer 4

• Intellectual activity and speech
• Contains motor cortex (voluntary motor movement)

Question 5

Temporal Lobe

Answer 5

• Hearing

Question 6

Parietal Lobe

Answer 6

• Speech, Communication, sensory
• TTTPP (taste, touch, temperature, pain, pressure)

Question 7

Occipital Lobe

Answer 7

• Vision

Question 8

Corpus Callosum

Answer 8

• Connects left and right hemispheres
• Deep groove between the left and right sides of the brain

Question 9

Cerebellum

Answer 9

• Controls involuntary motor movement (balance, coordination and fine muscle movements)
• Receives sensory information from the semicircular canals, eyes and proprioceptors

Question 10

Medulla Oblongata

Answer 10

• Swollen extension of the spinal cord
• Regulates involuntary actions of the autonomic nervous system; breathing, heart rate, swallowing, vomiting and constriction of blood vessels

Question 11

Hypothalamus

Answer 11

• Controls drives, body temperature regulation and thirst
• Controls the pituitary gland

Question 12

Pons

Answer 12

• Bridge located between midbrain and medulla

Question 13

Thalamus

Answer 13

• Located below the cerebrum
• “Screens” sensory information so it can direct attention to stimuli of interest
• Relay station
