What else can I help you with?
Individual hairs are columns of cells that died after becoming filled with?
keratin
What cells are mostly dead and filled with protein called keratin?
Hair cells
What is a keratin filled cyst and what causes it?
A keratin-filled cyst, also known as an epidermoid cyst, is a non-cancerous growth filled with keratin protein and dead skin cells. It forms when skin cells move deeper into the skin instead of shedding normally, usually due to a blockage of a hair follicle or damage to the skin.
Is a feather made from cells?
Yes, a feather is made up of cells. Feathers are composed of a protein called keratin, which is produced by the cells in the feather follicles. The keratin forms the structure of the feather, providing strength and flexibility.
Where do female sex cells develop?
In follicles which are found in the ovaries.
What are the strands of protein called when epidermal cells are pushed toward the surface and develop in their cytoplasm?
The strands of protein are called keratin. As epidermal cells move towards the surface and develop, they fill with keratin, creating a tough and protective barrier on the skin.
Is nail plate originate from karatin-containing follicle?
No, the nail plate does not originate from a keratin-containing follicle. Instead, it is formed from specialized epithelial cells in the nail matrix, located under the base of the nail. These cells produce keratin, which hardens to form the nail plate as it grows out. The process is similar to hair growth, but nails do not develop from hair follicles.
Is hair primarily composed of dead skin cells?
Yes, hair is primarily composed of a protein called keratin, which is produced by hair follicles in the skin. While hair itself is not alive, it is formed from living cells in the hair follicles.
What layer of the skin is composed of dead squamous cells filled with keratin?
papillary layer
Is hair made out of cells if not what is?
Hair is made out of keratin, a type of protein that is produced by cells in hair follicles in the skin. These cells divide and differentiate to form hair strands, which are composed primarily of keratin proteins.
Is a filament composed mainly of dead cells filled with the protein keratin?
Yes, a filament, such as hair or nails, is primarily composed of dead cells that contain the protein keratin. Keratin provides structural strength and resilience, allowing these filaments to serve their protective functions. As the cells die and harden, they form the visible part of the filament, while the living cells below continue to produce more keratin.
What is the uppermost layer of skin consisting of flat keratin-filled cells?
The uppermost layer of skin is the the stratum corneum.
