The term giant is sometimes used when describing nevi. A giant nevus covers a very large part of the body, usually involves the torso, and is usually accompanied by a number of satellite nevi. Satellite nevi (or just satellites) are smaller melanocytic nevi. When a child is born with a giant nevus, it is common for satellite nevi to be present at birth.
Receptors for the various neurotransmitters are located on both the presynaptic and postsynaptic nerve terminals of the neuron.hey are present in all of the nerve cells, but predominately in the ganglia or nerve bundles of invertebrates, and in the central nervous system (brain and spinal cord) of vertebrates. There are many kinds of neurotransmitter chemicals.
At rest, neurotransmitter-containing vesicles are stored at the terminal of the neuron in one of two places. A small number of vesicles are positioned along the pre-synaptic membrane in places called active zones.. This is where neurotransmitter release occurs.
