The initial response to a stimulus involves which process?

• action

• integration

• interpretation

• reception

• transmission

Afferent neurons:

• transmit information to the central nervous system

• provide support for the neurons

• connect motor and sensory neurons

• transmit information from the central nervous system to effectors

The myelin sheath:

• is a protein covering around dendrites

• is responsible for integrating information

• is a fatty covering only around axons

• stores neurotransmitters in the axon

• is a fatty covering only around cell bodies

Which of the following provides insulation for the neuron?

• synapse

• axon

• dendrite

• Schwann cell

• Node of Ranvier

The structure labeled 3 in the accompanying figure is:

• a node of Ranvier

• a cell body

• a dendrite

• a synaptic terminus

• an axon

The function of the structure labeled 5 in the accompanying figure is:

• insulation

• neurotransmitter release

• binding neurotransmitters

• conduction of an electrical signal

• acting as a ligand-gated channel

The function of the structure labeled 6 in the accompanying figure is:

• insulation

• neurotransmitter release

• binding neurotransmitters

• conduction of an electrical signal

• acting as a ligand-gated channel

The structure in the figure that is specialized to receive stimuli and send signals to the cell body is labeled:

• 1

• 3

• 4

• 6

• 7

Gaps in the myelin sheath are referred to as:

• synapses

• neuroglia

• microglia

• Schwann cells
