Biopsychology Axon A Cell body keeps cell alive

Biopsychology ____ Axon A. Cell body – keeps cell alive ____Dendrite B. Contains DNA and coordinates cellular activity ____Myelin Sheath C. Receives information from other neurons and relays it to the cell body ____Nodes of Ranvier ____Nucleus ____Soma ____Terminal Branches D. Carries information to other neurons, muscles or glands. E. Insulating material (made of glial cells) that encases some axons Neuron Nucleus Terminal branches Nodes of Ranvier Synaptic vesicle Glial Cells _______ ratio with neurons F. Gap in myelin that facilitates transmission of nerve impulses G. Forms junctions with other cells ____Terminal Buttons H. Contains synaptic vesicles that secrete neurotransmitters Supply ____________, remove ___________, and provide _____________ is a disease in which myelin is attacked by the body’s own immune system. Area between one neuron’s axon terminal and another’s dendrites is the _________. When a neuron fires, it releases _______________, which cross the synaptic gap & bind to _________ on the receiving neuron (lock and key) Excess neurotransmitters are reabsorbed by the terminal buttons of the sending neuron in a process called ____________. Neurotransmitters ____________: Contributes to regulation of attention, arousal, sleeping, dreaming, learning, and memory. Lack is associated with __________________: Contributes to control of voluntary movement, motivation, pleasure, and emotional arousal. Lack is associated with _________ and too much is associated with ________________: Involved in regulation of sleep and wakefulness, eating, and aggression. Lack is associated with ____________, and too much is associated with _______.

Neurotransmitters ____________: Contributes to regulation of attention, arousal, sleeping, dreaming, learning, and memory. Lack is associated with __________________: Contributes to control of voluntary movement, motivation, pleasure, and emotional arousal. Lack is associated with _________ and too much is associated with ________________: Involved in regulation of sleep and wakefulness, eating, and aggression. Lack is associated with ____________, and too much is associated with ________ is involved in regulation of anxiety and is the major inhibitory neurotransmitter. Lack is associated with __________ and ___________ are related during exercise and excitement and produce well-being and euphoria. They resemble opiates in structure and dull the experience of pain. Action Potential __________ pick up chemical signals from neurotransmitters that cross the synapse. These signals affect ____________ of the cell (make it more positively or negatively charged). _____________ signals say, “Fire”, and ______________ signals say, “Hold your fire”. If enough positive signals are given, an ____________ occurs. Goes by ____________principle; either fire or it doesn’t. Electric impulse travels through dendrite and soma. Jumps along the __________ (speeds transmission). Causes _____________to release neurotransmitters. After firing, there is a ____________ during which the neuron cannot fire again. Neuroplasticity - the brain has the ability to change and adapt as a result of experience. Three examples of neuroplasticity are:
