Corneous

Corneous describes something that is horn-like in substance, composition, or texture. It refers to a material primarily composed of keratin, the same protein that makes up horns, nails, claws, hooves, and the outer layer of skin in animals.

The term "corneous" is often used in biological and anatomical contexts to describe structures or tissues. It can also be used more generally to describe something that is hard, tough, and resembling horn in its physical properties. Examples include:

• Corneous Layer: This refers to the outermost layer of the epidermis, the stratum corneum, which is composed of dead, flattened cells filled with keratin. This layer provides a protective barrier against the environment.

• Corneous Tissue: This can describe any tissue primarily composed of keratinized cells, such as the material that makes up bird beaks or reptile scales.

• Corneous Growth: This might refer to an abnormal growth or thickening of the skin that results in a hardened, horn-like texture.

The word is derived from the Latin word "corneus," meaning "horny." The adjective describes a quality or characteristic relating to the physical and chemical properties of horn.
