The cells that serves as the basic building block of the body's information processing system

• neurotransmitters

• vesicles

• neurons

• glial cells

The branch like extensions of nerve cells that receive incoming signals from sensory receptors or from other neurons are called:

• axons

• synapses

• terminal branches

• dendrites

An action potential refers to a

• neural impulse

• synaptic gap

• neurotransmitter

• reflex

The resting potential of a neuron refers to

• a brief electrical charge that travels down the axon

• the storage of neurotransmitter molecules within synaptic vesicles

• the electrical imbalance between the inside and outside the neural membrane

• a capacity to reabsorb neurotransmitter molecules released into the synaptic gap

The effects of neurotransmitters can be best categorized as:

• important or unimportant

• strong or weak

• excitatory or inhibitory

• neural or glandular

Neurotransmitters receptor sites are primarily located on the

• dendrite

• myelin sheath

• axon

• cell body

Neurotransmitters are chemical messenger that travel across the

• cell body

• synaptic gap

• axon

• threshold

The two major components of the nervous system are

• somatic nervous system and the autonomic nervous sytem

• central nervous system and the peripheral nervous system

• sympathetic nervous system and the parasypathetic nervous system

• hormonal system and the endocrine system

Chemical messengers of the endocrine system are called:

• neurotransmitters

• hormones

• genes

• blood cells

The "master" gland

• pineal

• thyroid

• hypothalamus

• pituitary
