Episode Four Briefing: Vocabulary Terms All of the words below are ones that students will encounter while playing Episode Four: Mystery of Morpheus. Their definitions are contained within the adventure in either the InfoArchives or the Glossary. Teachers should alert the students to the ability to click on the hot-linked words in the game. After the game, teachers may want to review the new vocabulary words. Axon: a long, fiber-like extension of a neuron that transmits signals from the cell body to the synapse. Brain: located in the skull, it is the organ that controls all body activities through the spinal cord and peripheral nerves of the nervous system. Codeine: a naturally occurring component (alkaloid) of opium. It is capable of inducing sleep, relieving pain, and causing addiction, but it is weaker than the opiates morphine and heroin in producing these effects. Dendrite: a fiber-like extension of a neuron that receives signals from other cells. Endogenous opioid: also known as an endorphin. It is a substance which is produced by the body and which affects the brain much like morphine does. Endorphin: a brain chemical that acts like morphine. The word endorphin is a combination of two words-- endogenous, meaning made by the body, and morphine. Heroin: an illegal, highly addictive drug. It is both the most abused and the most rapidly acting of the opiates. It is made from morphine, a naturally occurring substance extracted from the fruit of certain varieties of poppy plant. Morphine: a naturally occurring component (alkaloid) of opium. It is the principal analgesic found in opium and is capable of inducing sleep and causing addiction. The Reconstructors 5 Mystery of Morpheus Episode Four Briefing: Vocabulary Terms Nervous system: a network composed of the brain, spinal cord, and the peripheral nerves. The network receives, interprets, and transmits signals in order to coordinate bodily activities. Neuron: a nerve cell. It is specialized to transmit and receive signals. Neurotransmission: the transfer of a signal from the axon of one neuron to the dendrite of another. Neurotransmitter: a chemical used by neurons to transmit signals to neurons and to other cells. Opiate: Opium, or a drug made from opium. Opium: the juice from the fruit of the opium poppy. Opium is capable of relieving pain, inducing sleep, and causing addiction. It has a milky-white appearance and turns brown and gummy upon exposure to air. Peripheral nerves: nerves that carry signals between the body and the spinal cord. Receptor: a structure on the surface of a neuron where neurotransmitters attach in order to transmit a signal. Reward Pathway: the part of the brain where feelings of pleasure are produced. Spinal cord: a bundle of nerves coming from the base of the brain. The spinal cord carries signals from the brain to the body, relays information from the body to the brain, and coordinates many reflexes. The Reconstructors 6 Mystery of Morpheus Episode Four Briefing: Vocabulary Terms Synapse: a gap between two neurons. It is the site where signals are transferred from one neuron to another. Vagus nerve: one of the peripheral nerves. One of its most important functions is to regulate heart rate. Vesicle: in cells, a spherical structure in which chemicals are stored.
