Abstract:

The study was conducted on the skin of 36 goat foetus between 23 to 150 days of gestation with objective to record the sequential histological changes that take place during the differentiation of muscles in the dermis of chin region of prenatal goat. The material was divided into three groups viz. Group I (below 50 days of gestation), Group II (51-100 days of gestation) and Group III (101 days of gestation to full term) containing 12 foetii each group. The skin samples were collected and processed and stained as per standard histological technique. In the dermis of chin region the muscles began to appear as myocyte at the age of 70 days gestation and were usually localized in the deeper half of dermis. They assumed fiber like profile from 75 days gestation and from 99 days gestation the differentiating muscle fibers showed resemblance to the characters of skeletal muscles. Distinct cross striations in the muscles of dermis became evident from 106 days of gestation. From 108 days onwards the skeletal muscles gradually became pronounced and extended superficially in the dermis. These muscles were is close apposition to sinus hair follicles present in the region but were not associated to the ordinary hair follicles. The arrector pili muscles which are generally found with hair follicles of other regions were not observed in the dermis of chin region.
