TERM 1 Biological Psychology DEFINITION 1 mind and body TERM 2 Definiton of Nervous System DEFINITION 2 system of cells that allow an organism to gain information about what is going on inside and outside the body and to respond appropriately TERM 3 Neurons DEFINITION 3 1.electrically excitable cell that processes and transmits information by electrical and chemical signaling. 2. especially goodat receiving signals from and transmitting signals to other neurons.3. have cell bodies and two types of fibers, called axons and dendrites TERM 4 Axons DEFINITION 4 An axon is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body. TERM 5 Dendrites DEFINITION 5 branched projections of a neuron that act to conduct the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project. TERM 6 glial cells DEFINITION 6 non-neuronal cells that maintain homeostasis, form myelin, and provide support and protection for neurons in the brain, and for neurons in other parts of the nervous system TERM 7 synapse (gaps) DEFINITION 7 In the nervous system, a synapse is a structure that permits a neuron to pass an electrical or chemical signal to another cell. TERM 8 Action potentials DEFINITION 8 In physiology, an action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in one end of an axon to another. An action potential is faster if wrapped in myelin sheath TERM 9 What chemical is released when an action potential reaches the end of an axon? DEFINITION 9 Neurotransmitter TERM 10 What happens at special sites called neural receptors? DEFINITION 10 the neurotransmitter crosses the synapse and interacts with the postsynaptic cell.This interaction cause a postsynaptic potential. TERM 21 A small structure between the hindbrain and forebrain that relays info from the eyes, ears, and skin and that controls certain types of automatic behaviors? DEFINITION 21 midbrain TERM 22 An area of the midbrain involved in smooth beginning of movement? DEFINITION 22 substantia nigra TERM 23 A structure within the forebrain that is involved in the smooth beginning of movement? DEFINITION 23 Striatum TERM 24 The most highly developed part of the brain; it is responsible for the most complex aspects of behavior and mental life? DEFINITION 24 Forebrain TERM 25 What is the thalamus? DEFINITION 25 A forebrain structure that relays signals from most sense organs to higher levels in the brain and plays an important role in processing and making sense out of this info TERM 26 What does the hypothalamus control? DEFINITION 26 regulates hunger, thirst, and sex drive. Contained in forebrain.It has many connections to and from the autonomic system, as well as to other parts of the brain. TERM 27 What does the suprachiasmatic nuclei generate? DEFINITION 27 Biological rhythms TERM 28 What is the limbic system and what are its two main structures? DEFINITION 28 It is a set of brain structures that play important roles in regulating emotion and memory.Amygdala and hippocampus TERM 29 What does the hippocampus form? DEFINITION 29 New memories. If damage is done to this area, you may lose the ability to remember new events (anterograde amnesia)Alzheimers stems from degenration of neurons in specific regions of the hippocampus TERM 30 The cerebral hemispheres make up the ____ and ____sides of the brain. DEFINITION 30 left and right TERM 31 The cerebral cortex is the ____surface of the brain. DEFINITION 31 outer TERM 32 What does Brochas Area involve? DEFINITION 32 Speech and the gestures affiliated with it.In frontal lobe TERM 33 What is wernickes area involved with? DEFINITION 33 it interprets both speech and written words. In temporal lobe
