Synapses
Voltage change during an action potential
Outline the sequence of events that
leads to an action potential being
passed across a synapse.
Label the diagram below to show which areas of the graph
represent the following key words: resting potential,
hyperpolarisation, resting potential restored,
depolarisation, repolarisation, refractory period
Non-myelinated neurones
Outline how an action potential is
transmitted through a non-myelinated
neurone.
Myelinated neurones
Synapses
Label the diagram of a synapse with as many key terms
as possible.
With reference to the diagram above, outline how an
action potential is transmitted through a myelinated
neurone
Structure of neurones
Resting potential
Label the neurone with the following terms: cell
body, axon, nucleus, dendrites, Schwann
cells, nodes of Ranvier, axon terminals.
Reflex arc
Label the sensory, relay and motor neurones,
a synapse, receptor and spinal cord.
Describe how the structures above are used to
maintain the resting potential of a cell.
The cell above is a motor neurone. It carries
electrical impulses from the central nervous
system to the effector. Draw a simple sketch
Action potential
of and name where the following neurones
transmit information from and to:
Sensory neurone
Relay neurone
What is the:
Stimulus?
Effector?
Receptors
Receptor
Energy change it detects
Response?
Definitions
Generator potential
Action potential
Describe how the structures above are used to create
an action potential following a stimulus in a cell.
