QUIZ QUESTIONS WITH CORRECT
ANSWERS
Main parts of the neuron - ANSWERS soma (cell body), axons (transmit info), dendrites (receive info)
axon terminals (conduct messages)
Function of a neuron - ANSWERS Convey a message
The Dendrites - ANSWERS Branch like extensions of the cell body, allows neurons to connect to a
large no of other neurons.
The cell body (soma) - ANSWERS Soma receives messages from other neurons through the
dendrites
Soma has one other extension called the axon
Axon - ANSWERS When the stimulation reaches a point the axon hillock initiates an impulse that
runs along the >>>>
fatty myelin sheath - ANSWERS Axons are enclosed in it
Insulates the axon
Separated by small gaps called nodes of Ranvier
Conducts impulse much faster
Impluse jumps from node to node
Axon terminal (telondendria) - ANSWERS Ends in a small node called Bouton terminal
Bouton terminal - ANSWERS Contains tiny containers called vesicles fill with neurotransmitters.
Chemical substances that play a roll in conducting a message
Synapse cleft - ANSWERS The gap at the junction of the synapse.
, Neurotransmitters - ANSWERS Regulate the communication between neurons
sensory neurons (afferent) - ANSWERS carry information from the senses to the brain
motor neurons (efferent) - ANSWERS Conduct messages from the spinal cord and the brain to the
muscles and glades
Nerve tract - ANSWERS When the nerve is in the spinal cord or brain
Nerve - ANSWERS When the nerve is in parts of the body (excluding brain/spinal cord
Impulse conduction - ANSWERS process by which messages are relayed in neurons, from one
neuron to the next
Electrical impulse - ANSWERS Begins in the first segment of the axon
Travels down the axon to the terminals because of electrical events at the cell membrane
Chemical impulse - ANSWERS determines if the impulse will be conducted across the gap
resting membrane potential - ANSWERS the electrical charge of a neuron when it is not active but
polarised
Cell Membrane - ANSWERS contains a mechanism that allows some ions through and prohibits
others
When a neuron is ready - ANSWERS + outside - inside
absolute refractory period - ANSWERS neuron doesnt respond to any stimulus
Axon cannot conduct an impulse
Refractory period - ANSWERS the membrane returns the soduim and potassium ions to the original
states
