Term | Definition |
Three major functions of the nervous system | Sensory input, integration, motor output |
Sensory input | Monitors changes occurring inside and outside the body |
Integration | Processes and interprets sensory input (information processing) |
Motor output | Response to information processed |
Composed of the brain and spinal cord | Central nervous system |
Subdivision of the PNS that controls voluntary activities such as the activation of skeletal muscles | Somatic nervous system |
Composed of cranial and spinal nerves | Peripheral nervous system |
Subdivision of the PNS that regulates the activity of cardiac muscle (the heart), smooth muscle, and glands; it is also called the involuntary nervous system | Autonomic nervous system |
A major subdivision of the nervous system that interprets incoming information and issues orders | Central nervous system |
A major subdivision of the nervous system that serves as communication lines, linking all parts of the body to the CNS | Peripheral nervous system |
Support, insulate, and protect cells/neurons | Neuroglia |
Demonstrate irritability and conductivity, and transmit electrical messages from one area of the body to another | Neurons |
Release neurotransmitters (general) | Neurons |
Are amitotic (cannot divide) | Neurons |
Able to divide; therefore are responsible for most brain neoplasms | Neuroglia |
Releases neurotransmitters (specific; neuron anatomy) | Axon terminal |
Conducts electrical currents toward the cell body | Dendrites |
Increases the speed of impulse transmission | Myelin sheath |
Location of the nucleus | Cell body |
Conducts impulses away from the cell body | Axon |
