Asked in Premeth Test 30 — Circulation

Purkinje fibers are connected with the impulse conducting system of:

Correct answer: A. Heart

  • A. Heart
  • B. Brain
  • C. Skin
  • D. Nephron

Explanation

The correct answer is Option A: Heart. Purkinje fibers are a critical component of the heart's impulse conducting system. They rapidly transmit electrical impulses, which orchestrate the nearly simultaneous contraction of the ventricles, facilitating efficient blood circulation. In contrast, the brain relies on neurons for impulse transmission, the skin uses nerve endings for sensory signaling, and the nephron uses epithelial cells for its physiological processes.
