Histological description of wild boar (Sus scrofa) skin from Timor Island

Abstract

The purpose of this study was to examine the histological structure of wild boar skin. This research used three wild boar samples from Timor Island, aged five to six months, with skin collected from the lumbo dorsalis, abdominal ventralis, and dorsal interscapularis regions of each animal. Sampling, specimen preparation, and Hematoxylin-Eosin (HE) staining were conducted at the Laboratory of Anatomy, Physiology, Pharmacology, and Biochemistry (AFFB), Faculty of Veterinary Medicine, Nusa Cendana University. The results showed that wild boar skin is composed of three layers: the epidermis, dermis, and hypodermis. The epidermis consists of four layers: stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. The dermis includes the dermal papilla and reticular dermis, composed of dense connective tissue containing collagen and elastic fibers. In this layer, primary hair follicles, sebaceous glands, arrector pili muscles, and blood vessels were observed. The hypodermis is composed of loose connective tissue with abundant fat cells, where secondary hair follicles and sudoriferous glands were found.
