Question

Which is the primary structural unit of the kidney?

Answers

  1. Neuron
    • Rationale:

      A neuron is a specialized cell that transmits nerve impulses. It is not a primary structural unit of the kidney.

  2. Nanism
    • Rationale:

      Nanism is a medical term that refers to the condition of being abnormally or exceptionally small in stature. It is not a primary structural unit of the kidney.

  3. Nephron
    • Rationale:

      Nephron is the medical term that refers to each of the functional units in the kidney. Each nephron consists of a glomerulus and its associated tubule by which the glomerular filtrate passes before emerging from the body as urine.

  4. Neuralgia
    • Rationale:

      Neuralgia is a burning, stabbing, and often severe pain that is caused by irritation or damage to a nerve cell. It is not a primary structural unit of the kidney.
