send sensory signals to brain and spinal cord
What are receptors?
sensory nervous system
What detects and transmits information from the receptors?
excitability
What is responsiveness to a stimulus?
axon hillock
What is where the cell body attaches to the axon?
multipolar
What are neurons that have many dendrites and one axon?
Determines the response to sensory input
What are the brain and spinal cord?
motor nervous system
What initiates and transmits information to the effectors?
conductivity
What is the ability to propagate electrical signals?
axoplasm
What is analogous to general cells cytoplasm in neurons?
bipolar
What are neurons that have one dendrite and one axon?
Main functions of the nervous system
What are communication and control?
somatic sensory
What is sensory input from the receptors of the five senes?
secretion
What is the release of neurotransmitters in response to conductive activity?
synaptic knobs
What is where synaptic vesicles are stored?
unipolar
What are neurons that only have one process extending from the cell body?
Brain and spinal cord send output to
What are effectors?
visceral sensory
What is sensory input from the internal organs?
extreme longevity
What is cells can live throughout a person's lifetime?
axon
What is a long process emanating from neuron body?
axonic
What are neurons that have dendrites but no axon?
collect, process and evaluate, and respond to stimuli

autonomic motor
What is motor output from involuntary organs?
amitotic
What is after fetal development, mitotic activity stops?
dendrites
What is the part of the neuron that receives input?
interneurons
What are neurons that communicate between sensory and motor neurons?
