Why are psychologists conerned with human biology?

Put the events of a neural impulse in the correct order.

• a chemical message is received by dendrites exceeding the neurons' threshold

• neuron at rest has a stable electrical balance

• an impulse is triggered called the action potential which sends an electrical charge down the axon

• the neuron undergoes a short rest, called a refractory period before it can fire again.

• the message exits the neuron through the axon terminals and into neighboring neurons

Match the following

• axon

• cells in the nervous system that support, nourish, and protect neurons

• cell body

• a neuron's often bushy, branching extensions that receive and integrate messages

• dendrites

• a fatty tissue layer enabling greater transmission speed during neural impulse

• glial cells

• part of a neuron that contains the nucleus; the cell's life support

• myelin sheath

• a segmented neuron extension that passes messages through its branges to other neurons, or to muscles or glands
