What are keratinocytes?

Keratinocytes are the most prominent cell within the epidermis. Keratinocytes are ectodermally derived and can be distinguished from melanocytes and Langerhans cells in the epidermis by their larger size, intercellular bridges, and ample cytoplasm. Keratinocytes are present in all four layers of the epidermis.

What is the thin top layer of the skin called?

The epidermis is the thin outer layer of the skin. It consists of 2 primary types of cells: Keratinocytes. Keratinocytes comprise about 90% of the epidermis and are responsible for its structure and barrier functions.

Listen to pronunciation. (PA-pih-LAYR-ee DER-mis) The thin top layer of the dermis (the inner layer of the skin). The papillary dermis has connective tissue and blood vessels that give nutrients to the epidermis (the outer layer of the skin) and that help control the temperature of the skin.

What is visceral fascia?

The term ‘visceral fascia’ is a general term used to describe the fascia lying immediately beneath the mesothelium of the serosa, together with that immediately surrounding the viscera, but there are many types of visceral fasciae.

What is the difference between superficial fascia and deep fascia?

The key difference between superficial and deep fascia is that the superficial fascia is between the skin and muscle, while the deep fascia is between muscles. Fascia is an important structure in our body. It provides a framework for all connective tissues.

Is epidermis a connective tissue?

The epidermis is composed of epithelial tissue, and the dermis is connective tissue.

What is the difference between keratinocytes and melanocytes?

The main difference between keratinocytes and melanocytes is that keratinocytes form a barrier to the mechanical damage of the skin whereas melanocytes protect the skin from UV by producing melanin.

What are nucleated keratinocytes?

Nucleated keratinocytes indicate parakeratosis, erosions, or that the sample was obtained from below the stratum corneum. Acantholytic keratinocytes are cells that have lost their desmosomal attachments and therefore have a rounded appearance when they are seen in pemphigus diseases.

Where is the stratum corneum?
