Hemorrhages occur from the larynx, bronchial membrane, intestinal surfaces, and even into the parenchyma of the viscera, the muscles, serous membranes, periosteum, and neurilemma.

Around this bundle of neurones, that is around the nerve, is still another wrapping, silvery-white, called the neurilemma.

Surrounding the axis cylinder is a thick, whitish-looking layer, known as the medullary sheath, and around this is a thin covering, called the primitive sheath, or neurilemma.

The deeply stained oblong nuclei indicate the nerve corpuscles within the neurilemma.

The whole is enclosed in a thin, delicate sheath, known as neurilemma.
