These nuclei are believed to be in connection with a delicate sheath corresponding with the neurolemma of the medullated nerve fiber. |
These sensations are carried by medullated nerve fibres, and are slow to return after injury to the nerves. |
Between the neurolemma and the axis cylinder is the medullated sheath, composed of a fatty substance known as myelin. |
The neurilemma of a medullated fibre contains myelin laid down by Schwann cells. |
