The ____ receives incoming information in a neural pathway
A
pre-synaptic neuron
B
post-synaptic neuron
C
axon terminal
D
synaptic gap
Explanation: 

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.

Detailed explanation-2: -When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.

Detailed explanation-3: -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-4: -The dendrites of neurons receive information from sensory receptors or other neurons. This information is then passed down to the cell body and on to the axon. Once the information has arrived at the axon, it travels down the length of the axon in the form of an electrical signal known as an action potential.
