Answer 2

is by initiating muscular contractions or glandular secretions

Question 3

What is the central nervous system made up of?

Answer 3

the brain and the spinal cord

Question 4

What is the peripheral nervous system made up of?

Answer 4

is made up of neurons throughout the rest of the body

Question 5

What does the sensory and motor neuron pathways in the PNS do?

Answer 5

they information to and from the CNS via electrical impulses

Question 6

What does the brain do with the information sent from neurons?

Answer 6

analyses, interprets, processes and stores.

Question 7

What two nervous systems can the peripheral nervous system be divided into?

Answer 7

Somatic and autonomic.

Question 8

What parts of the body does the somatic nervous system include?

Answer 8

spinal nerves

Question 9

What does the somatic nervous system control?

Answer 9

the body’s skeletal muscles

Question 10

What is the somatic nervous system is responsible for?

Answer 10

bringing about certain involuntary actions e.g. limb withdrawal as a reflex action, conducting involuntary impulses to smooth muscle, cardiac muscle and glands. But most control is voluntary movements, such as walking and speaking.

Question 11

What is the autonomic nervous system responsible for?

Answer 11

regulating the internal environment by controlling structures and organs such as the hearts, blood vessels, bronchioles, alimentary canal.

Answer 14

decreases heart rate, breathing rate

increases peristalsis, intestinal secretions

Question 15

What is sympathetic responses also known as?

Answer 15

fight or flight

Question 16

What is parasympathetic responses also known as?

Answer 16

rest and digest

Question 17

What is the function of the medulla?

Answer 17

regulates the basic life processes of breathing, heart rate, arousal and sleep

Question 18

What is the function of the cerebellum?

Answer 18

responsible for controlling balance, posture and movement

Question 19

Which parts of the brain are the central core?

Answer 19

medulla, cerebellum

Question 20

What are the functions of limbic system?

Answer 20

processing information for memories and influencing emotional and motivational states.

Question 21

What is the cerebal cortex?

Answer 21

Cerebral cortex is the centre of conscious thought; it also recalls memories and alters behaviour in the light of experience.

Question 22

What is the function of the cerebal cortex?

Answer 22

receiving sensory information, coordinating voluntary movement and making decisions in the light of experience.

Question 23

What side of the brain will process information from the right visual field?

Answer 23

left

Question 24

What side of the brain will process information from the left visual field?

Answer 24

right

Question 25

What is the function of the sensory areas?

Answer 25

receives information as sensory impulses from receptors.

Question 26

What is the function of the association areas?

Answer 26

analyse and interpret impulses received from the sensory areas and deals with thought processes, language, personality, imagination and intelligence.

Question 27

What is the function of the motor areas?

Answer 27

act on information from association areas by sending motor impulses to effectors.
