How Do You Spell STRATUM GRANULOSUM?

Pronunciation: [stɹˈɑːtəm ɡɹˈanjʊlˌɒsəm] (IPA)

The correct spelling of the term "Stratum Granulosum" is tricky due to its use of both Latin and Greek roots. The first part of the word, "stratum," comes from Latin, meaning "layer." The second part, "granulosum," comes from Greek, meaning "grainy." The correct pronunciation of this term is /strætəm ɡrænjəloʊsəm/, with stress on the first syllable of each word. It refers to the granular layer of skin between the top layers and the epidermis.

STRATUM GRANULOSUM Meaning and Definition

1. The term "stratum granulosum" is used in the field of anatomy and histology to describe a specific layer of the epidermis, which is the outermost layer of the skin. The stratum granulosum is the fourth layer from the base of the epidermis and is located above the stratum spinosum.

   In this layer, the cells undergo a process called keratinization, where they begin to lose their nuclei and organelles, and instead become filled with a highly fibrous and protective protein called keratin. These keratin-filled cells, also known as granular cells, give the stratum granulosum its name.

   The primary function of the stratum granulosum is to provide a barrier and protection to the underlying layers of the skin. The granular cells produce and release lipids that help to form a waterproof barrier on the skin's surface, preventing excessive water loss and protecting the body against harmful external environmental factors.

   Additionally, the stratum granulosum plays a role in the production of vitamin D. When exposed to sunlight, cells in the stratum granulosum convert a precursor molecule into an active form of vitamin D, which is important for calcium absorption and overall bone health.

   Overall, the stratum granulosum is an essential component of the epidermis, serving both protective and functional roles in maintaining the integrity and health of the skin.

2. (1) Granular layer, a layer of flattened cells containing granules of keratohyalin and eleidin, lying just above the s. mucosum of the epidermis; (2) The outer layer of cells surrounding the ovum in the Graafina follicle; (3) stratum nucleare retinae.
