Capitolo 5, Problema 14
Which epidermal cells contain keratohyaline and lamellar granules?
Guida verificata passo dopo passo1
Understand that the epidermis is composed of several layers of cells, each with distinct functions and characteristics.
Recall that keratohyaline granules are involved in the process of keratinization, helping to form the dense protein matrix in the skin's outer layer.
Recognize that lamellar granules contain lipids that contribute to the skin's waterproof barrier by filling spaces between cells.
Identify the specific epidermal cell type that contains both keratohyaline and lamellar granules; these are the cells in the stratum granulosum layer.
Conclude that the keratinocytes in the stratum granulosum are the epidermal cells containing keratohyaline and lamellar granules, playing a key role in skin barrier formation.

Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Epidermal Cell Types
The epidermis consists of several cell types, including keratinocytes, melanocytes, Langerhans cells, and Merkel cells. Keratinocytes are the most abundant and are responsible for producing keratin and other granules essential for skin barrier function.

Other Epidermal Cells
Keratohyaline Granules
Keratohyaline granules are dense, protein-rich structures found in the granular layer of keratinocytes. They contain profilaggrin, which helps in the aggregation of keratin filaments, contributing to the formation of the skin’s protective outer layer.

Lamellar Granules
Lamellar granules are lipid-containing organelles in keratinocytes that release lipids into the extracellular space. These lipids form a waterproof barrier, preventing water loss and protecting the skin from external environmental damage.
