Granulated sugar

Granular layer refers to a layer of small cells found in various structures of the body, including the cerebellum, the skin, and the kidney. The term is often used in neuroscience and histology to describe the specific layer of cells in these structures.

Granular layer in the cerebellum[edit | edit source]

In the cerebellum, the granular layer is the deepest of the three layers that make up the cerebellar cortex. It contains densely packed granule cells, which are small neurons that play a crucial role in the processing of information in the cerebellum. The granular layer also contains Golgi cells, which are inhibitory interneurons that regulate the activity of granule cells.

Granular layer in the skin[edit | edit source]

In the skin, the granular layer, also known as the stratum granulosum, is one of the layers of the epidermis, the outermost layer of the skin. It is located between the stratum spinosum and the stratum corneum. The cells in the granular layer, known as keratinocytes, are characterized by the presence of keratohyalin granules, which are involved in the process of keratinization, the formation of a protective layer of dead skin cells.

Granular layer in the kidney[edit | edit source]

In the kidney, the term granular layer can refer to the layer of cells in the renal corpuscle that contains podocytes, specialized cells that play a key role in the filtration of blood to form urine. The granular layer can also refer to the layer of cells in the renal tubules that are involved in the reabsorption and secretion of various substances.
