Question 1

what are the lobes of the brain?

Answer 1

• frontal lobe
• partial lobe
• occipital lobe
• temporal lobe

Question 2

what are the main parts of the frontal lobe?

Answer 2

• primary motor cortex
• pre-motor cortex
• broncas area

Question 3

where is the primary motor cortex located? what is its functions?

Answer 3

frontal lobe
- allows conscious control of precise, skilled, voluntary movements
-

Question 4

where is the pre-motor cortex found? what is its functions?

Answer 4

frontal lobe

- controls learned repetitious, or patterned motor skills

Question 5

what are the main parts of the parietal lobe?

Answer 5

• somatosensory cortex

- somatosensory association cortex

Question 6

where is the somatosensory cortex located? what is its function?

Answer 6

parietal lobe

• receives sensory information from the skin, skeletal muscle and joints
• capable of spatial discrimination: identification of body region being stimulated

Question 7

where is the somatosensory association cortex located? what is its function?

Answer 7

parietal lobe

- integrates sensory information from primary somatosensory cortex

Question 8

what are the main parts of the occipital lobe?

Answer 8

• primary visual (striate) cortex

- visual association cortex

Question 9

what is the occipital lobes main function?

Answer 9

its main function os the processing, integration, interpretation, etc of vision and visual stimuli

Question 10

where is the primary visual (striate) cortex located? what’s its function?

Answer 10

Occipital lobe

- receives visual input from the retina via the optic nerve

Question 11

where is the visual association cortex located? what is its function?

Answer 11

occipital lobe

- uses past visual experiences to interpret stimuli

Question 12

what is the temporal lobes main function?

Answer 12

they play a role in hearing, language comprehension, memory and information retrieval

Question 13

where is the primary auditory cortex found? what is its function?

Answer 13

temporal lobe

- interprets information from inner ear as pitch, loudness and location

Question 14

what does the diencephalon house?

Answer 14

thalamus, hypothalamus, epithalamus

Question 15

what does the thalamus do?

Answer 15

• Gateway to cerebral cortex

- sorts, edits, and relays information

Question 16

what does the Hypothalamus do?

Answer 16

• Autonomic control centre for many visceral functions
• Centre for emotional centres
• Regulates body temperature, food intake, water balance and thirst

Question 17

what does the epithalamus contain

Answer 17

contains pineal gland

Question 18

what are the parts of the brainstem?

Answer 18

midbrain, pons, medulla oblongata

Question 19

what nerves are associated with the medulla?

Answer 19

VIII - vestibulcochlear
X - vagus
XII - Hypoglossal

Question 20

What does the cerebellum do?

Answer 20

• Subconsciously provides precise timing and appropriate patterns of skeletal muscle contraction
• A “blueprint” of coordinated movement is sent to the cerebral motor cortex and to brain stem nuclei
• Plays a role in word association and puzzle solving
