Document Summary
2 lecture 1 outline: neurons, nerves, and the nervous system. Branch of the life sciences that deals with the structure and functioning of the brain and neurons, nerves and nervous tissue that form the nervous system: behavioral neuroscience. Specialized cell in the nervous system that receives and sends messages within that system: soma. Dendrites are attached to this cell body, contains the nucleus and keeps entire cell alive and functioning: dendrite. Serve as a structure on which the neurons develop and work and hold neurons in place: oligodendrocytes. Produce myelin for the neurons in the brain and the spinal cord: schwann cells. Produce myelin for the neurons of the body: myelin. Synapse at which a neurotransmitter causes the receiving cell to fire: inhibitory. Synapse at which a neurotransmitter causes the receiving cell to stop firing: what are the ways in which drugs can affect neural communication, antagonist. Chemical substance that blocks or reduces the effects of a neurotransmitter: agonist.
