  • The scientist observed that the medullated fibers conducted nerve impulses much faster than the unmyelinated ones.

Examples

  • In the nervous system, medullated axons are faster than unmyelinated ones.

  • During the lesson, the professor explained how the medullated axons differ from non-medullated ones in structure and speed.

  • Damage to medullated nerves can disrupt normal motor function and sensation.

  • The medullated fibers are crucial for fast signal transmission.

  • Damage to medullated nerves can disrupt normal motor function and sensation.

  • In the nervous system, medullated axons allow for quicker transmission of signals between the brain and muscles.

Morphology

medullated = medullate (semi-transparent) = medulla + ate + ed

The form 'medullated' is a regular -ed form of 'medullate', but both 'medullate' and its root 'medulla' are specialised anatomical terms not familiar to general learners.

Etymology

Medullated comes from the Latin word medulla meaning 'marrow' or 'inner part'. A helpful way to remember it is to think of a 'marrow-like' covering: a medullated nerve has a soft sheath called myelin that wraps the nerve and helps signals travel faster.
