Neuroanatomy Intro

Question 1

CNS function

Answer 1

• centre of all mental activity (thought, learning, memory)
• regulates and maintains homeostasis (with endocrine system)

Answer 4

cranium

Question 5

what surrounds spinal cord

Answer 5

vertebrae

Question 6

what surrounds CNS

Answer 6

three layers of meninges

Question 7

what occurs during the sensory input stage

Answer 7

Receptors detect internal or external stimuli and relay information towards
CNS (afferent neurones)

Question 7

what occurs during the integration stage

Answer 7

Analysis, Storage, Decision making, Perception

Question 8

what occurs during motor output stage

Answer 8

Muscular contraction, Glandular Secretion

Question 9

neurone type for sensory input stage

Answer 9

afferent

Question 10

neurone type for integration stage

Answer 10

interneurones

Question 11

neurone type for motor output stage

Answer 11

efferent neurones

Question 12

what occurs in the frontal lobe

Answer 12

decision making and control of voluntary movement

Question 13

what occurs in the temporal lobe

Answer 13

• processing memories
• integrating memories emotions and senses

Question 14

what occurs in the parietal lobe

Answer 14

processing sensory and spatial information

Question 15

what occurs in the occipital lobe

Answer 15

vision

where does spinal cord end

Answer 19

space between L1 and L2

Question 20

3 functions of the spinal cord

Answer 20

• conduit for motor information (down spinal cord)
• conduit for sensory information (up spinal cord)
• a centre for co-ordinating certain reflex

Question 21

PNS

Answer 21

peripheral nervous system

Question 22

structure of PNS

Answer 22

cranial nerves and spinal nerves

Question 23

function of PNS

Answer 23

communication lines between CNS and rest of the body

Question 24

structure of sensory or afferent division of PNS

Answer 24

somatic and visceral sensory nerve fibres

Question 25

function of sensory or afferent division of PNS

Answer 25

conducts impluses from receptors to the CNS

Question 26

structure of motor or efferent division of CNS

Answer 26

motor nerve fibres

Question 27

function of motor or effernt division of PNS

Answer 27

conduits impulses from CNS to effectors (muscles and glands)

Question 28

structure of somatic nervous system

Answer 28

somatic motor (voluntary)

Question 29

function of somatic nervous system

Answer 29

conducts impulses from CNS to skeletal muscles

Question 30

structure of autonomic nervous system

Answer 30

visceral motor (involuntary)

Question 31

function of autonomic nervous system

Answer 31

conducts impulses from CNS to cardiac muscles, smooth muscles and glands

function of sympathetic division of ANS

Answer 32

mobilises body systems during activity
