Document Summary

Contract pupils, constricts bronchi, slow heartbeat, stimulates activity, Neurons dilates vessels: the basic units of the human nervous system, sensory neurons, motor neurons, interneurons. Connecting sensory and motor to the brain. Resting membrane potential: a neuron at rest is polarized, has more negative electrical charge inside than outside. How neurotransmitters work: agonist drug that can increase how much neurotransmitters is made so there is more inside each vesicle, the can block the reuptakes of neurotransmitters. Treat depression: can mimic a particular transmitter, can either activates or increases the neurotransmitter"s effect, antagonists decrease the release on neurotransmitter so there are fewer, the can help destroy neurotransmitters in the synapse. Treat hyperactive perhaps: can mimic a particular transmitter, can block the neurotransmitter binding. The brain: redline receptor send signal to the brain for processing. Signal travel through sensory neurons and spinal cords: blue line to produce a response sent from brain to the body through spinal cord and motor neurons.
