1. Biological Psychology
6 action potential
A branch of psychology concerned with the links between biology and behavior.
A nerve cell; the basic building block of the nervous system.
The bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body.
The extension of a neuron, ending in branching terminal fibers, which messages pass to other neurons or to muscles or glands.
A layer of fatty tissue segmentally encasing the fibers of many neurons
A neural impulse; a brief electrical charge that travels down an axon. The axon potential is generated by the movement of positively charged atoms in and out of channels in the axons membranes.
The level of stimulation required to trigger a neural impulse.
The junction between the axon tip of the sending neuron and the dendrite of the cell body of the receiving neuron.
Chemical messengers that traverse the synaptic gaps between neurons. When released
A neurotransmitter that enables learning and memory and also triggers muscle contraction.
Natural, opiate like neurotransmitters linked to pain control and to pleasure. Tree

16 Sensory neurons
17 motor neurons
19 Somatic nervous system
20 autonomic nervous system
21. sympathetic nervous system
The body’s speedy electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems.
The brain and spinal cord
The sensory and motor neurons that connect the central nervous system to rest the body.
Neural “cables” containing many axons. These bundled axons, which are part of the peripheral nervous system, connect the central nervous with the muscles, glands, and sense organs.
Neurons that carry incoming information from the sense receptors to the central nervous system.
Neurons that carry outgoing information from the central nervous system to the muscles and glands.
Central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs.
The division of the peripheral nervous system the controls the body’s skeletal muscles.
The part of the peripheral nervous system that controls the glands and the muscles of the internal organs. Its sympathetic division arouses; its parasympathetic division calms.
The division of the automatic nervous system that arouses the body mobilizing its energy in stressful situations. Command center
22 Parasympathetic nervous system
24. Neural Networks
25 Endocrine System
27 Adrenal Glands
28. Pituitary Gland
31. PET (position emission tomography)
The division of the automatic nervous system that calms the body, conserving its energy.
A simple. Automatic, inborn, responses to a sensory stimulus, such as the knee-jerk response.
Interconnected neural cells
The body’s chemical communication system; a set of glands that secrete hormones into the bloodstream.
Chemical messengers, mostly those manufactured by the endocrine glands.
