Neurons Flashcards
fundamental physiological properties of neurons
excitability, conductivity, and secretion
sensory neurons
detect stimuli and transmit information about them to the CNS
conduct signals towards the CNS
interneurons are located
within the CNS
interneurons receive signals from
many other neurons
interneurons carry out the
integrative function of the nervous system
what do interneurons do with information
process, store, and retrieve it
interneurons determine
how the body responds to stimuli
motor neurons send signals to
muscle and gland cells
motor neurons conduct signals
away from the CNS
multipolar neuron has how many axons?
one
multipolar neuron has how many dendrites?
multiple
what is the most common type of neuron?
multipolar neurons
multipolar neurons include most neurons of the
brain and spinal cord
how many axons do bipolar neurons have?
one
how many dendrites do bipolar neurons have?
one
example of a bipolar neuron
olfactory cells of the nose
neurons in the retina
anatomy of a unipolar neuron
single process leading away from the soma
example of a unipolar neuron is a neuron that carry signals to the
spinal cord for sense such as touch and pain
how many dendrites do anaxonic neurons have?
multiple
how many axons do anaxonic neurons have?
none
anaxonic neurons do what through dendrites?
communicate
do anaxonic neurons produce action potentials?
no
an example of an anaxonic neuron would be in the retina
to help visual processes such as perception of contrast
