GENERAL HISTOLOGY

Detailed explanation-1: -Synapses: Dendrites receive signals from other neurons at specialized junctions called synapses. There is a small gap between two synapsed neurons, where neurotransmitters are released from one neuron to pass the signal to the next neuron.

Detailed explanation-2: -The surface of the dendrites is filled with receptors that become enacted upon by neurotransmitters that traversed the synapse after the pre-synaptic neuron fired and released neurotransmitters into the synapse.

Detailed explanation-3: -Dendrites extend out from the cell body and receive messages from other nerve cells. An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles.

Detailed explanation-4: -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-5: -Synaptic vesicles contain a neurotransmitter (NT) and release it when their membranes fuse with the outer cell membrane. Neurotransmitter molecules cross the synaptic cleft and bind to receptors known as ligand-gated ion channels (LGICs) and G-protein–coupled receptors (GPCRs) on the postsynaptic neuron.
