The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.
The production and release of substances such as NEUROTRANSMITTERS or HORMONES from nerve cells.

Peptides
Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.

APUD Cells
Cells with the capacity to take up and decarboxylate the amine precursors DIHYDROXYPHENYLALANINE or 5-HYDROXYTRYPTOPHAN. This is a property of endocrine cells of neural and non-neural origin. APUDOMA is a general term collectively applied to tumors associated with APUD cells.
