Neurohormones are produced by which type of cells?

• A. Muscle cells
• B. Nerve cells
• C. Immune cells
• D. Epithelial cells

Answer: (B)

Neurohormones are peptides or small proteins released by nerve cells, specifically neurons, that act as hormones and can affect other distant cells in the body. This process involves the secretion of these signaling molecules into the bloodstream, allowing them to influence various physiological functions beyond the immediate vicinity of their origin. For example, neurohormones can be involved in regulating stress responses, reproductive functions, and various metabolic processes.

While muscle cells primarily function in contraction and movement, immune cells focus on defense against pathogens and do not produce neurohormones. Epithelial cells, which line body surfaces, are responsible for secretion and absorption but do not play a role in neurohormone production. Thus, the unique role of nerve cells in the synthesis and release of neurohormones clearly identifies them as the correct answer.
