What is a nerve impulse?
Your body's reaction to a certain event.
An electric signal that passes through neurons.
A message passed through the blood.
Electrical signal created in the brain.
True or false?
Sensory neurones carry impulses from the brain and spinal cord to muscles and glands
True
False
Which structure speeds up the transmission of electrical impulses along the axon?
Myelin sheath
Dendrites
Axon terminals
What is the purpose of synapses?
To stop two neurons from touching each other
To allow two neurons to interact with each other
To ensure nerve impulses travel in one direction
To stop neurons from communicating with each other
Name the three different types of neurones:
sensory, generalised and motor neurones
Sensory, relay and motor neurones
Sensory, relay and effector neurones
A sense organ has lots of _________.
effectors
tissue
mitochondria
receptors
What is the region where nerve cells meet called?
Synapse
Cleft
Junction
Axon terminal
A nerve impulse is transmitted in which direction
1 to 2 to 3
3 to 2 to 1
What is the function of the axon?
Protect the neurone
Accelerate the flow of nerve impulse
Coordinate metabolic activities
Carry impulse from body cell to effector
What is the function of the Node of Ranvier?
Protect the neurine
Accelerate the flow of nerve impulse
Coordinates metabolic activities
Send signal to muscle
What are the differences between the sensory neurons (SN) and motor neurons (MN)?
SN has long dendrite whereas MN has short dendrite
SN has myelin sheaths whereas MN does not.
SN cell body is at the side of the cell but MN is at the end of the cell
SN has receptor whereas MN does not.
Label the Neuron-What does the letter "C" represent?
Cell Body
Dendrite
Axon Hillock
Myelin Sheath
4 is the Synaptic Cleft
4 is the Post Synaptic Neuron/Cell
4 is the Pre-Synaptic Neuron/Cell
How does neurotransmitter cross the synaptic cleft?
exocytosis
simple diffusion
carrier mediated transport
osmosis

Name this neurone.
Sensory neurone

Motor neurone
What is the function of Dendrite?
Intakes information from other neurons
Produces fatty tissue for the Myelin Sheath
Sends information to the next cell
Controls the speed of electrical signal through the axon
What direction for the electrical signal travel through a neurone?
From dendrites, into the cell body, down the axon and out axon terminals
From Axon terminals, down the Axon, & out of the dendrites
Any direction up or down the cell
From the Axon, to the Dendrites, and out the Axon terminals
If a neurone does not have a myelin sheath, the transmission of impulse will be slower compare with a myelinated neurone.
True
False
