Skin

Thick Skin, Human

Identify the various layers of the epidermis(keratinised stratified squamous epithelium) - namely, the stratum basale(germinativum), stratum spinosum, stratum granulosum, stratum lucidum and a stratum corneum. The underlying dermis consists of dense, vascular connective tissue. Can you find the adipose subcutaneous tissue? Note the dermal papillae and the corresponding wavy lines of the epidermis. The keratinised layer is thick and appears structureless. Identify sweat glands and their ducts. In the dermis, or hypodermis, look for Pacinian corpuscles, arterioles and a few peripheral nerve fibres or bundles.
