    a. Stimulant and depressant
    b. Motor neuron and sensory neuron
    C. Brain stem and diencephalon
    d. Resting potential and action potential Answer
    a. Stimulant is a drug which increases (stimulates) the activities of the nervous system.
    Depressant is a drug which lowers (depress) the activities of the nervous

    b. Sensory neuron is a neuron that gets information about what is going on system.
    inside and outside of the body and brings that information into the brain or
    the spinal cord.
    Motor neuron is a neuron that gets information from the brain or spinal cord
    and conveys commands to the effector organs such as muscles and glands.

    C. Brain stem is a part of the brain that consists of midbrain, pons and medulla
    oblongata.
    Diencephalon is a part of the brain that consists of thalamus and
    hypothalamus.

    d. Resting potential is the state in which the neuron is not conducting a nerve
    impulse.
    Action potential is the state in which the neuron is conducting a nerve
    impulse.
    Action potential is a localised change in the resting membrane potential
    between the inside and outside of the nerve fibre caused by a stimulus
