216 THE ORGANS 



Nerves. — The terminations of nerves in muscle and tendon are 

 described under nerve endings (page 440). 



TECHNIC 



(i) A Muscle. — Select a small muscle, human or animal, and, attaching a 

 weight to the lower end to keep it stretched, fix in formalin-Miiller's fluid (tech- 

 nic 6, p. 7), and harden in alcohol. Stain transverse sections with ha^matoxylin- 

 picro-acid-fuchsin (technic 3, p. 21) and mount in balsam. 



(2) Junction of Muscle and Tendon. — Any muscle-tendon junction may be 

 selected. Fix in formalin-Miiller's fluid, keeping stretched by means of a weight 

 attached to the lower end. Cut longitudinal sections through the muscle- 

 tendon junction, stain with hsematoxylin-picro-acid-fuchsin, and mount in bal- 

 sam. The gastrocnemius of a frog is convenient on account of its small size, and 

 because by bending the knee over and tying there, the muscle can be easily put 

 on the stretch and kept in that condition during fixation. Place the entire prepa- 

 ration in the fixative removing the muscle-tendon from the bone after fixation.
