divisions of the nervous system

Question 1

what is part of the central nervous system

Answer 1

All the neurons within the brain and
spinal cord.
All the parts of the nervous system within the spinal column and skull

Question 2

what is part of the peripheral nervous system

Answer 2

All the parts of the nervous system that are outside the brain and spinal cord.

Question 3

what do the spinal cord and brain do

Answer 3

main controllers of neural activity and behaviour

Question 4

the nervous system is made up of which 2 subsystems

Answer 4

the central nervous system and the peripheral nervous system

Question 5

what are the 2 divisions of the peripheral nervous system

Answer 5

somatic and autonomic nervous system

Question 6

what does the somatic nervous system contorl

Answer 6

voluntary muscle movement of skeletal muscle

Question 7

what does the autonomic nervous system control

Answer 7

involuntary activity of non skeletal muscle and internal body systems

self regulating

Question 8

what are the divisions of the autonomic nervous system

Answer 8

sympathetic and parasympathetic nervous system

Question 9

the sympathetic nervous system is which one

Answer 9

the fight or flight response

Question 10

the parasympathetic nervous system is whihc one

Answer 10

the rest and digest one

Question 11

what are the 2 divisions of the peripheral nervous system (not somatic and autonomic)

Answer 11

sensory (afferent) division and motor (efferent) division

Question 12

what does the sensory afferent division do

Answer 12

sends sensory input to the cns

Question 13

what does the motor efferent division do

Answer 13

sends motor signals from the cns to muscles and glands

Question 14

what are the 4 lobes of the cerebrum

Answer 14

frontal, parietal, occipital, termporal

Question 15

what is the frontal lobe involved in

Answer 15

thought, speech production, impulse control, and working memory

Question 16

what does the parietal lobe process

Answer 16

sensory information eg touch, pain temperature

Question 17

what does the occipital lobe process

Answer 17

visual information

Question 18

what does the temporal lobe involved with

Answer 18

hearing and language comprehension

Question 19

the brain stem is responsible for regulating…… which are essential for….. eg

Answer 19

regulating autonomic function which are essential for life eg breathing, heartbeat, swallowing

Question 20

the brain stem includes which strucutre

Answer 20

medulla oblongata

Question 21

where is the cerebellum located

Answer 21

sits beneath the back of the cerebrum

Question 22

what is the cerebellum involved in controlling

Answer 22

motor skills balance and coordinating muscles

Question 23

the brain stem allows impulses to pass between the

Answer 23

brain and the spinal cord

Question 24

where is the diencephalon located

Answer 24

on top of the brain stem

Question 25

which 2 structures does the diencephalon contain

Answer 25

the thalamus and the hypothalamus

Question 26

the hypothalamus regulates (3)

Answer 26

body temp, hunger and thirst

Question 27

the hypothalamus acts as the link between

Answer 27

the endocrine system and the nervous system

Question 28

the thalamus acts as a relay station for nerve impulses coming from …….. and is also involved in several functions inc ……/…..

Answer 28

nerve impulses coming from the senses

sleep/wakefullness

Question 29

the spinal cord consists of …… pairs of spinal nerves

Answer 29

31

Question 30

what is the main function of the spinal cord

Answer 30

to relay info between the brain and the rest of the body

enabling the brain to monitor and regulate internal bodily processes and coordinate voluntary movement

Question 31

how are the nerves arranged in the spinal cord (hint; roots)

Answer 31

each nerve divides into 2 roots
one root contains sensory neurons so sensory info can be transmitted to the brain
the other roots contains motor neurons so motor signals can be transmitted to skeletal muscles and internal organs

Question 32

the spinal cord also allows for …….. without direct involvement of the …….

Answer 32

simple/quick reflexes

Question 34

identify the 2 components of the peripheral nervous system and explain 2 differences in their organisation and/or functions (4)

Answer 34

the components are the somatic nervous system and the autonomic nervous system

the sns has sensory and motor pathways while the ans is purely motor

the ans controls internal organs and glands of the body while sns controls skeletal muscle and movement

the ans control centres are in the brain stem whilst sns carries commands from the motor cortex
