OF THE MUSCULAR SYSTEM. 



§ 76. 



To this system belong all the transversely striped muscles, 

 which, together with their accessory appendages, the tendons 

 and fasciae, serve for the movements of the skeleton, of the 

 proper organs of sense, and of the integuments. These muscles 

 constitute a system situated between the integuments and 

 the bones, and between the bones themselves, the individual 

 parts of which are so associated and united by common 

 membranes, that they may conveniently be regarded as a 

 whole, 



§77. 



The proper elements of the muscles in question, visible even 

 to the naked eye — the transversely striated (animal or volun- 

 tary) muscular fibres, or primitive fasciculi, — are distinguished, 

 especially by their size and the distinctness of their individual 

 parts, from those of most of the striped muscles occurring in other 

 situations (heart, large venous trunks, pharynx, oesophagus, 

 larynx, urethra). AYith respect to this latter characteristic, it 

 is to be remarked that the sheath of the primitive fasciculus, 

 or the sarcolemma? in every fasciculus without exception, 



' [It is greatly to be doubted whether the universality of the occurrence of this 

 structure should be so strongly affirmed. We have been unable to detect it either 

 in the muscular bundles of the heart, or in the great majority of those of the tongue, 

 or in any of the muscles of a seven months' foetus. In fact, the question of the 

 existence of a sarcolemma as an independent structure, very much resembles that of 

 the existence of " fibrils." The sarcolemma must be considered merely as the outer 

 portion of the transparent, homogeneous matrix, in which the " sarcous elements" are 

 imbedded (vide infra) ; and the possibility of raising it up by artificial means, or of 

 observing its optical expression, as a distinct structure, will depend upon the amount 

 to which it is developed relatively to the various elements — and the extent of 

 chemical differentiation which has gone on it as compared with the rest of the 

 matrix. — Eds.]
