Saltatory transmission occurs in:
Correct answer: B. Myelinated nerve fiber
- A. Non myelinated nerve fiber
- B. Myelinated nerve fiber
- C. Cell body
- D. Continuous fashion
Explanation
Myelinated nerve fibers are axons that are surrounded by a myelin sheath, which acts as an insulating layer. In these fibers, the action potential "jumps" or "skips" between the nodes of ranvier, which are small gaps in the myelin sheath. This is called saltatory conduction and is much faster compared to continuous transmission.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
