    bodies, wliicb are unipolar, containing a vesicular nucleus with a distinct nucleolus and often yellowish-brown ])igment- granules. A nucleated capsule always surrounds the cells, and this is probably only a continuation of Schwanifs sheath. The (/aiif/lia contain small multipolar cells, having some ])igment, often two nuclei, and are surrounded by a capsule. Nerve-Terminations.—Through these endings the sensory impulses are transmitted to the central nervous system, and motor impulses transmitted from the nervous system to pei’ipheral organs. The nerve-endings are the final termina- tions of the individual neurons. There are free nerve-endings Fig. 33. 7ly Termination of nerves by free ends. Two nerves terminating in the stratified epithelium covering the vocal cords of the cat. n, nerve-trunk. (Retzius.) wliicli are not connected directly with other tissues in order to give or receive impulses, and other specialized nerve-endings in which the nerve-ending is connected with some other tissue : ns epithelial, eonneetive, muscle, and nervous tissues, to form its termination. Tlie nerve-fibres terminate in four ways : 1. The iuterepithelial arliorizations ; 2. The motor ])lates in muscles ; d. The s])ecial eud-organs in sensory tissues ; 4. The tactile corpuscles.
