LESSON V. 

 CONNECTIVE TISSUE. 



A. CONNECTIVE-TISSUE FIBRES. 



1. Elastic Fibres. 



a. Tease out. in water a morsel of ligamentum 

 nuchae. It is almost entirely made up of 

 rather large branching, and anastomosing 

 fibres having distinct outlines, and curling at 

 their ends. 



6. Irrigate -with acetic acid (1 to 5 p.c.); the 

 fibres are unaffected. 



2. White Fibres. 



a. Place on a slide a small piece of a thin 

 tendon, e.g. from a digit of a frog or from 

 the tail of a mouse (cp. B. 3) and, keeping 

 it in position at one end with a needle, 

 separate as completely as possible the fibres 

 from one another at the other end by passing 

 a needle through it in the direction of its 

 length. If the unteased end of the tendon 

 is so thick that it would tilt up the cover slip, 

 separate with needles a small outer portion
