Term
Central Nervous System
Definition
Consist of the brain, vertebrates, and spinal cord
Term
Peripheral nervous system
Definition
made mostly of nerves that carry signals into and out of the CNS
Term
Ganglia
Definition
Found in PNS, clusters of neuron cell bodies
Term
Sensory input
Definition
the conduction of signals from sensor receptors
Term
integration
Definition
the analysis and interpretation of the sensory signals and the formulation of appropriate responses
Term
motor output
Definition
conduction of signals from the integration centers
Term
Effector cells
Definition
perform body responses
Term
sensory neurons
Definition
convey signals from sensory receptors into CNS
Term
internerons
Definition
located entirley within the CNS
Term
motor neurons
Definition
convey signals from CNS to effector cells
Term
Dendrites
Definition
branched extensions that recieve signals from other neurons and convey this information toward the cell body
Term
axon
Definition
longer exention that transimts singals to other cells
Term
Glia
Definition
nourishes neurons, insulate axons of neruons, or help maintain homeostasis of extracellular fluid surrounding neurons
Term
Myelin sheath
Definition
insulating material
