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.
Acetylcholine receptors are primarily located __________. on the motor end plate. Receptors for acetylcholine are located on the motor end plate -- the portion of the muscle fiber's sarcolemma that faces the neuron's synaptic terminal.Binding of acetylcholine to acetylcholine receptors increases the sodium permeability of the motor end plate.This causes sodium to rush into the muscle fiber, which generates a muscle action potential. An action potential in the muscle fiber causes __________.inding of acetylcholine to acetylcholine receptors increases the sodium permeability of the motor end plate. This causes sodium to rush into the muscle fiber, which generates a muscle action potential.
