PATHOLOGY

Detailed explanation-1: -Dendrite – The receiving part of the neuron. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs determining whether the neuron will fire an action potential. Spine – The small protrusions found on dendrites that are, for many synapses, the postsynaptic contact site.

Detailed explanation-2: -Basically, a postsynaptic neuron adds together, or integrates, all of the excitatory and inhibitory inputs it receives and “decides” whether to fire an action potential. The integration of postsynaptic potentials that occur in different locations-but at about the same time-is known as spatial summation.

Detailed explanation-3: -The postsynaptic side of the synapse is specialized to receive the neurotransmitter signal released from the presynaptic terminal and transduce it into electrical and biochemical changes in the postsynaptic cell.

Detailed explanation-4: -The parts of neurons that send messages are the axons, and the parts of neurons that receive messages are the dendrites. 3. The space between the dendrites of one neuron and the axon of another neuron is called the synapse.
