Neurons Flashcards
what is the basic function of neurons in the CNS
receive, integrate and transmit information
name the 3 types of neurons
sensory
motor
interneurons
what is a sensory neuron
carry information from the sensory organs and tissues and transmit nerve impulses to the CNS
what is a motor neurons
carry nerve impulses from the CNS to tissues
where are interneurons found
found only within the CNS
what is an axon
cytoplasmic extension which relays information away from the neurons
what happens when the concentration of K+ is highest inside the cell, what happens to the outside of the cell?
high outside the cell
what do sodium potassium pumps do
use energy of ATP to maintain these K+ and Na+ gradients across the plasma membrane
what is it called when; if a depolarization shifts the membrane potential sufficiently, it results in a massive way in the membrane voltage
action potential
the point of connection between two communicating neurons is called the?…
synapse
what is the synapse
junction between the axon and the neuron and the target cell
where does action arrive
at the end of an axon
where does the short term memory associate within the brain
hippocampus
