Skeletal muscles are innervated by:Question 5Answera.Large, unmyelinated fibersb.Medium unmyelinated fibersc.Large, myelinated fibersd.Small, unmyelinated fiberse.Small, myelinated fibers
Solution
The correct answer is c. Large, myelinated fibers.
Here's why:
Skeletal muscles are innervated by somatic motor neurons, which are large, myelinated fibers. Myelination increases the speed of impulse conduction along the nerve fiber, which is crucial for quick, coordinated muscle movement. The large diameter of these fibers also contributes to the speed of conduction. Therefore, skeletal muscles, which require rapid
