Define the following terms: neuron, axon, dendrite, myelin sheath, afferent neuron, efferent neuron, association neuron.
Match each type of membrane potential (resting, threshold, graded, or action) to its definition:
a) The membrane potential at which voltage gated sodium channels open.
b) The membrane potential that triggers the action potential.
c) Change in membrane potential that may or may not reach threshold and that may be depolarizing or hyperpolarizing.
d) Rapid, strong depolarization followed by immediate repolarization. This potential is self-renewing if the right ion channels are nearby.
Identify and describe specific structures of a neuron.
Neurons: dendrites, cell body, axon
Neuroglia
Sensory neuron, interneuron, motor neuron
Axon with myelin

Label the presynaptic and postsynaptic ends of each neuron, the cell bodies, dendrites, axons, axon hillock and axon terminals, location of voltage gated Ca²+ channels, location of voltage gated Na+ channels, location of voltage gated K* channels, location of Na*/ K+ pumps, location of neurotransmitter storage, location of neurotransmitter receptors. Consider your drawing and describe the function of neurons. Include an explanation why neurons are considered polarized cells and how this relates to their function. (Polarized here is not referring to membrane potential as all cells have a membrane potential). This means you will need to explain the location of different channels in the neuron and the relationship of the channels to the function of a neuron.arrow_forwardIdentify and label the following structures on the neuron model figure below: cell body, dendrites, neuron nucleus, neurolemma, axon hillock, nucleus of Schwann cell, Nissl bodies, myelin sheath, axon, node of Ranvier, axon terminals (of neurons synapsing with model neuron), endoneurium (refer to Figure 10.6). 3) 11arrow_forward
