nervous system Flashcards
Many dendrites one axon
Multipolar
One dendrites one axon
Bipolar
Appears to have a single axon
pseudo-unipolar
Highly branched
astrocytes
Epithelial-like
ependymal cells
small, mobile cells
microglia
cell with process that can surround several axons
oligodendrocytes
single cell surrounding axons
Schwann cells
is an involuntary reaction in response to a stimulus applied to be periphery and transmitted to CNS
Reflex
Is the neuronal pathway by which a reflex occurs.
reflex arc
Basic functional unit of nervous system because it is the smallest simplest pathway capable of receiving a stimulus and yielding a response
Reflex arc
5 components of reflex arc
- sensory receptors
- sensory neurons
- interneurons
4.motor neuron - effector organ
2 simplest pathway of neurons
converging pathway
diverging pathway
Two or more Neurons synapse with the same postsynaptic neuron
converging pathway
the axon from One neuron divides and synapses with more than one postsynaptic neuron.
diverging pathway
