CH 9 Nervous System Review

Which type of cell communicates via electrical impulses?

• Neuroglia

• Neurons

• Epithelial cells

• Muscle cells

What do neurotransmitters convey?

• Electrical impulses from a neuron to another cell

• Nutrients to neurons

• Oxygen to tissues

• Hormones to glands

What is the response aspect of the nervous system called?

• Sensory input

• Integration

• Motor output

• Neuroglia

What do motor neurons conduct?

• Sensory information

• Nerve impulses to effectors

• Changes in the environment

• Coordination signals

What is the function of the myelin sheath?

• Decreases nerve impulse speed

• Increases conduction speed of nerve impulses

• Protects the synapse

• Connects neurons

What is the main function of dendrites in a neuron?

• Transmit signals away from the cell body

• Receive signals from other neurons

• Store genetic information

• Produce energy for the neuron

Which part of the neuron contains the nucleus?

• Axon

• Dendrites

• Cell body

• Synaptic knob

What is the direction of impulse conduction in a neuron?

• From axon to dendrites

• From myelin sheath to nucleus

What is the direction of impulse in a multipolar neuron?

• From axon to dendrites

• From dendrites to axon

• From axon to cell body

• From cell body to dendrites

What is the primary function of neuroglia?

• Generate nerve impulses

• Conduct nerve impulses

• Support neurons

• Transmit signals
