How Do You Spell STRATUM LUCIDUM?

Pronunciation: [stɹˈɑːtəm luːsˈɪdəm] (IPA)

Stratum Lucidum is a term used in anatomy and refers to a thin layer of clear, flattened cells found in the epidermis. The spelling of this word is tricky due to its Latin origin, where "stratum" means layer and "lucidum" means clear or bright. The correct way to pronounce the word is /ˈstreɪtəm luːˈsɪdəm/, with stress on the first syllable of Stratum and second syllable of Lucidum. The diphthong /uː/ in Lucidum represents the long sound of the letter 'u'.

STRATUM LUCIDUM Meaning and Definition

1. The term "stratum lucidum" refers to a distinct layer of the epidermis, which is the outermost layer of the skin. It is a translucent and thin layer found only in specific regions of thick skin, such as the soles of the feet and the palms of the hands. The stratum lucidum is located between the stratum granulosum and the stratum corneum.

   The stratum lucidum is composed of multiple layers of flattened, clear, and densely packed keratinocytes. These specialized cells possess a high concentration of eleidin, a protein that provides the translucent appearance and unique characteristics of this layer. These cells are less metabolically active compared to the other layers of the epidermis.

   The primary function of the stratum lucidum is to enhance the protective properties of the skin. Its presence reinforces the skin's resistance to friction, pressure, and potential damage. In addition, the stratum lucidum plays a vital role in maintaining skin hydration and preventing water loss. It acts as a barrier, preventing the entry of microorganisms and unwanted substances into the deeper layers of the skin.

   Overall, the stratum lucidum serves as a crucial element of the skin's defense mechanism, providing an extra layer of protection in areas of the body that are subjected to greater mechanical stress.

2. Clear layer, the layer of the epidermis just beneath the s. corneum; it consists of two or three layers of flat clear cells with atrophied nuclei.
