What is an event when one or more presynaptic neurons fire in rapid order it produces a much greater depolarization of the postsynaptic membrane than would result from a single ESPS?
temporal summation
How is information sent from one neuron to the next?
Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Information from one neuron flows to another neuron across a synapse. The synapse contains a small gap separating neurons. The synapse consists of: 1. a presynaptic ending that contains neurotransmitters, mitochondria and other cell organelles, 2. a postsynaptic ending that contains receptor sites for neurotransmitters and, 3. a synaptic cleft or space between the presynaptic and postsynaptic endings.
Describe the structure of a synapse?
The synapse consists of two main parts that allow one neuron to communicate with another: 1) the presynaptic terminal located at the end of an axon; and 2) the postsynaptic terminal located on the dendrite of another neuron. The presynaptic terminal is where neurotransmitters are stored and released from. The postsynaptic terminal is the recipient side of the synapse. Neurotransmitters released from the presynaptic terminal will diffuse across the synaptic cleft and bind to receptors located on the surface of dendritic spines.
Inter neuron relay impulses from where to where?
From sensory neurons to motor neurons
What sends impulses to the brain?
sensory neurons
What is the difference between presynaptic and postsynaptic neurons?
Presynaptic neurons release the neurotransmitter in response to an action potential. Postsynaptic neurons receive the neurotransmitter (and can however become presynaptic to the next nerve cell, if the neurotransmitter has stimulated the cell enough).
When two or more presynaptic neurons synapse with a single postsynaptic neuron in the CNS what pathway is formed?
Divergent
1 Neurons communicate with other neurons and stimulate both?
electrical and chemical impulses.

How do neurons stimulate or inhibit other neurons?
Stimulate

Point to point or saltatory conduction.

Motor Neurons
What neurons that move impulses from the brain?
