These tubes may be represented grossly by imagining the finger of a glove, to be called the sarcolemma, or muscle - fiber pouch, and this to be so small as not to be apparent to the naked eye, but filled with nuclei and the juices peculiar to each animal.
The tip of the axon makes intimate contact with the sarcolemma (sahr'koh-Iem'ub; "skin of the flesh" G), which is the membrane enclosing the muscle fiber.
Moreover, the muscle fibers of the heart are peculiar in that they are destitute of sarcolemma, the naked muscle fibers directly touching each other.
They have no sarcolemma, stripes, or cross markings like those of the voluntary muscles.
The fibrillæ, then, are bound together in a bundle to form a fiber, which is enveloped in its own sheath, the sarcolemma.
Each fiber is enclosed within a delicate, transparent sheath, known as the sarcolemma.
Within the sarcolemma are minute fibrils and a semiliquid substance, called the _sarcoplasm_.
Each cell has a well-defined nucleus, but the sarcolemma is absent.
At each end the cell tapers to a point from which the sarcolemma appears to continue as a fine thread, and this, by attaching itself to the inclosing sheath, holds the cell in place.
The striations, sarcolemma, and sometimes the nuclei and nerve plates, may be distinguished in such a preparation.
