21
Q

what are the two main divisions of the peripheral nervous system

A

somatic nervous system and autonomic nervous system

22
Q

what are the somatic system made up of (think neurons)

A

sensory and motor neurons

23
Q

what does the somatic nervous system do

A

recieves info from sensory receptors, they then relay messages to the CNS

24
Q

what does the Autonomic nervous system do

A

governs vital functions such as breathing, heart rate, digestion, sexual arrousal

25
Q

what ae the autonomic nervous systems 2 parts

A

sympathetic and parasympathetic

26
Q

what does the sympathetic nervous system do

A

response that helps us deal with emergencies (fight or flight), e.g increasing heart rate and bp

27
Q

where do the neurons from the sympathetic nervous system travel

A

every organ and gland, preparing the body for rapid action when individual under threat

28
Q

what does the sympathetic nervous system cause the body to release

A

stored energy, pupils to dilate and hair to stand on end.
slows bodily processes that are less important in emergencies e.g digestion and urination

29
Q

what does the parasympathetic nervous system do

A

relaxes us once an emergency has passed

30
Q

what does the parasympathetic nervous system do to the body

A

slows heartbeat down, reduce bp, restart digestion

31
Q

what is action potential

A

when neurons transmit info within and to other neurons. the dendrites of neurons recieve info from sensory receptors or other neurons. this info then passed to th cell bodyand on to the axon. then at the axon, travels down its lenght to form an electrical signal.

32
Q

what are the three types of neurons

A

sensory, relay, motor

33
Q

what do neurons consist of

A

cell body, dendrites, axon

34
Q

Function of the neurons part 1 (dendrites to cell body)

A

dendrites at one end of neurons receive signals from other neurons
dendrites protrude from cell body that carry nerve impulses from neighbouring neurons towards cell body

35
Q

functions of neurons part 2 (cell body to axon)

A

from the cell body the impulse is carried along the axon where terminated at the axon terminal

36
Q

functions of neurons part 3 (axon,myelin sheath)

A

axon covered in a fatty layer of myelin sheath that protect the axon and speed up electrical transmission of the impulse
the length of a neuron can vary from a few milimeters up to one metre

37
Q

function of neurons part 4 (synapse)

A

at the end of the axon are terminal buttons that communicate with the next neuron in the chain across the gap known as the synapse

38
Q

what are the role of sensory neurons

A

carry nerve impulses from sensory receptors (vision, taste, touch) to CNS. they convert info from sensory receptors into neural impulses.
when impulses reach the brain they translated into sensations
not all sensory info travel as far as the brain, with some neurons terminating in the spinal cord, allows reflex actions to occur quicker without delay of sending impulses to the brain

39
Q

what do relay neurons allow

A

sensory and motor neurons to communicate with eachother.

40
Q

where do relay neurons lie

A

within the brain, visual system and spinal cord

41
Q

where are motor neurons located

A

in the CNS. they project their axons outside the CNS to the PNS and to the control muscles

42
Q

what do motor neurons do

A

form synapses form synapses with muscles and control their contractions.
when stimulated the motor neuron releases neurotransmitters that bind to receptors on the muscle and trigger a response causing muscle movement
when the axon of the motor neuron fires, the muscle with which it has formed synapses with, contracts
muscle relaxation is caused by inhibitions of the motor neuron

43
Q

how are signals within neurons transmitted

A

electrically

44
Q

how are signals between neurons transmitted

A

chemically across the synapse

45
Q

what are in the motor neurons

A

cell body
dendrite
axon
myelin sheath
impulse director
axon terminal

46
Q

what are in the sensory neurons

A

dendrites
cell body
axon
axon terminal

47
Q

what is the neural network

A

when neurons communicate with each other in groups

48
Q

what is a synapse

A

where each neuron is seperated from the next by a tiny gap called a synapse

49
Q

what is synaptic transmission

A

when electrical impulses reach end of the neuron (pre-synaptic terminal) it triggers the release of neurotransmitters from tiny sacs called synaptic vesicles

50
Q

what are neuro transmitters

A

chemicals that diffuse across the synapse to the next neuron in the chain

A
