SENSIBILITY OF THE INTEENAL OEGANS 93 



this pressure beyond what is strictly uecessary to sustain the 

 weights. 



Anatomical proof that the muscles, tendons, and joints are 

 sensitive, owing not only to the sensory nerves that traverse them 

 to reach the skin, but also to the ^^ 

 fibres that terminate there, was 

 given by Eeichert, Kolliker, and 

 others. 



According to Kolliker the 

 sensory nerve -fibres of muscles 

 almost always run towards the 

 surface and ends of the muscle, 

 and terminate in the connective 

 tissue, perimysium, and tendons, 

 never in the sarcolemma of the 

 muscle-fibres.

(1889) first described in the muscle sheaths, tendinous sheaths, 

 and joint capsules, nerve-endings resembling Pacinian corpuscles, 

 of various forms and sizes, which differ slightly from those of the 

 subcutaneous connective tissues. A more minute description of 

 their conformation, topography, and relations was afterwards (1897) 

 given by Sherrington and Euffini (Figs. 38, 39). 



Kolliker (1862) and Kiihne (1863) discovered among the 

 ordinary muscle-fibres characteristic bundles containing a few
