Dendrite: –branched, treelike structure attached to the soma; receives information from other neurons.

Axon:–long, thin, cylindrical structure that conveys information from the soma of a neuron to its terminal buttons.

Myelin: insulatory material that covers the axons of many neurons, which have a function of covering the electrical impulses (similar to the isolation of electric cables).

Node of Ranvier:Are the spaces between the myelin coating on the neuron's axon. Electricity travels through the axon (wrapped in myelin).

Axon terminal: –– bud at the end of a branch of an axon; forms synapses with another neuron.]]> 2018-06-27 16:29:11 UTC https://padlet.com/lcorado90/qv3y8341w4sv/wish/268754423 Synapse lcorado90 https://padlet.com/lcorado90/qv3y8341w4sv/wish/268754432 Junction between the terminal button of an axon and the membrane of another neuron.]]> 2018-06-27 16:29:14 UTC https://padlet.com/lcorado90/qv3y8341w4sv/wish/268754432 Classification according to the function of the neuron lcorado90 https://padlet.com/lcorado90/qv3y8341w4sv/wish/268754440 Sensory neuron – a neuron that detects changes in the external or internal environment and sends information about these changes to the central nervous system.

Motor neuron – a neuron located within the central nervous system that controls the contraction of a muscle or the secretion of a gland.

Interneurons-  Between sensory & motor neurons in the Central Nervous System (reay messages from sensory neuron to motor neuron).

Bipolar: neuron with one axon and one dendrite attached it its soma.
–sensory systems (vision and audition)

Unipolar: •neuron with one axon attached to its soma; the axon divides, with one branch receiving sensory information and the other sending the information into the central nervous system.
–somatosensory system (touch, pain, etc)
