Abstract EN
The research includes a comparative histological and topographical study to the constituents of three different region : fore head ، intermandibular space and cheek of head skin in males and females black goat of 1_2year old.
Animals were slaughtered in one season (spring).
Histological study showed that the head skin of local black goat consists of two layers : epidermis and dermis.
The average total thickness of epidermis varied regarding to sex , it was higher in black goat males higher than in females in all of the studied regions .Within the same sex the epidermal thickness ranging between39.49_70.49µ in male while it was between 34.19_54.86 µ in females.
The dermis of frontal skin of black goat male was thicker than that of female while in both buccal skin and intermandibular skin the dermal thickness in females was higher than that of males .
The hair follicles in the three studied regions were of compound type .
Each compound hair is formed of a single primary follicle and a number secondary follicles of both sexes .
In frontal skin region of male goats , the length of primary hair follicles is greater than those of female goats , while the depth of these follicles in cheek and intermandibular space regions was higher in females than males .In both sexes , the compound hair follicles being arranged in groups of triads in all of the studied regions but groups of five compound follicles were also observed in frontal skin region of both sexes .
The hair density varied in the different regions of both sexes and being higher in females than in males .The sebaceous glands were larger in size in frontal skin of males than that those of females .
All sweat glands in the different studied regions of both sexes were of apocrine type.
The secretory units of sweat glands of female buccal skin region were extended deeper in the dermis than those of male.
