The follicles was arranged as groups consist mainly of three follicles (Trio), in addition to (Dio) and (Mono) arrangement, in this study we noticed the greater diameter of the primary and secondary wool follicles in the neck region and the deeper primary wool follicles present in neck region ,while the deeper secondary wool follicles present in middle dorsum.

In respect to the sebaceous glands, the present results indicate that they attached with the both types of wool follicles in which they opened at the upper part of the wool follicles via short duct the larger sebaceous gland found in neck region all the sweat glands of the skin of sheep were of Apocrine type, these glands which have large secretory parts and narrow duct were accompanied the primary wool follicle but the bigger sweat gland present in middle dorsum.
