This concept consists of four videos discussing issues associated with alcohol and drug abuse. Each video link is followed by a set of questions related to the video. Read the questions prior to watching the video. Think about the questions as you watch the video, and/or answer the questions after watching the video.
axon: Long, threadlike part of a neuron that transmits nerve impulses to other cells.
brain: Control center of the nervous system.
central nervous system: Main part of the nervous system; includes the brain and spinal cord.
dendrite: Extension of the cell body of a neuron that receives nerve impulses from other neurons.
depressant: Drug that has the opposite effects of a stimulant; makes you less alert.
drug abuse: Use of a drug without the advice of a medical professional and for reasons not originally intended.
motor neuron: Nerve cell that carries nerve impulses from the brain and spinal cord to organs, glands, and muscles.
nerve: Bundle of nerve cells.
nerve impulse: Electrical signal transmitted by the nervous system.
nervous system: Body system that sends electrical messages throughout the body; controls all other body systems.
neuron: Nerve cell.
neurotransmitter: Chemical that carries a nerve impulse from one nerve cell to another at the synapse.
sensory neuron: Nerve cell that carries nerve impulses from the sense organs and internal organs to the brain and spinal cord.
spinal cord: Long, tube-shaped bundle of neurons that runs from the brain stem to the lower back; carries nerve impulses back and forth between the body and brain.
stimulant: Drug that makes you feel more awake and alert.
