Most neurons have several 1. connectivity diagrams (for nerve ring and RVG region synapses), [the total number of synapses for each neuron = synapses in the diagram + synapses ATP is used by nerve cells to move ions across their cell membranes.

The tips of telodendrites of pre synaptic neuron contain acetyle choline secreting knobs. When the impulse reaches to the actyle choline knobs, the acetyle choline breaks from the knob and drops into the dendrite of post synaptic neuron.

Functions of Neurons. The central nervous system [CNS] is composed entirely of two kinds of specialized cells: neurons and glia. Hence, every information
Parts of a Neuron · Dendrites: are tree-like structures that extend away from the cell body to receive neurotransmitters from other neurons. · Synapses: Dendrites
The human nervous system consists of billions of nerve cells (or neurons)plus supporting (neuroglial) cells.

It can also be the point of communication between a neuron and a muscle or gland. The word ‘synapse’ is derived from the word ‘syn’; ‘syn’ means together. A synapse has dendrites of one axon and cell body of another axon.
