Myelinated nerve fibres are typically found in
Athe autonomous neural system
Bthe somatic neural system only
Cspinal and cranial nerves
Dthe retina of the eye
Answer & Solution
Correct answer: C. spinal and cranial nerves
1. Each fibre type has its own location.
2. Myelinated nerve fibres are found in spinal and cranial nerves.
3. Unmyelinated fibres are commonly found in the autonomous and somatic neural systems.
4. The retina is where bipolar neurons are found, which is a different classification.
5. Myelination is what allows the fast conduction those nerves need.
