What else can I help you with?
The ultimate fate of an epidermal keratinocyte is described by the term?
keratinization, where the keratinocyte undergoes a process of terminal differentiation and ultimately becomes a dead, flat cell filled with the protein keratin.
What is the main cell type in skin?
The main cell type in the skin is the keratinocyte. Keratinocytes make up about 95% of the cells in the epidermis, the outermost layer of the skin. They produce the protein keratin, which helps provide structure and protection to the skin.
What pigment is phagocytized by keratinocytes?
Melanocytes phagocytize melanin. First, melanocytes which are present in the lowest or basal layer of the epidermis, produce the pigment melanin. The melanin forms granules called melanosomes. After the keratinocytes take up the pigment, it clusters around the keratinocyte nucleus on the superficial side. This protects the DNA in the keratinocyte nucleus from damage due to UV radiation.
If a function is equal to zero when x is zero is the function considered defined at that point?
Yes. So long as the function has a value at the points in question, the function is considered defined.
Is the protein pump active or passive in its function?
The protein pump is active in its function.
What is the ratio of melanocyte to keratinocyte in skin?
1:36

What cell makes hair and fingernails grow?
A keratinocyte is the cell from which hair and fingernails are derived.

Which type of cell has the primary function of making the skin water tight?
The primary type of cell responsible for making the skin water tight is the keratinocyte. These cells produce keratin, a fibrous protein that helps form a protective barrier on the skin's surface. As keratinocytes mature, they undergo a process called keratinization, which enhances the skin's impermeability to water and prevents moisture loss. This function is crucial for maintaining skin hydration and overall integrity.
Which skin cell keratinocyte sudoriferous glandular epithelial cell arrector pili muscle cell fibroblast would form a junction with a motor neuron?
arrector pili muscle cell
What is the principal cell of the epidermis?
The principal cell of the epidermis is the keratinocyte. Keratinocytes are the most abundant cells in the epidermis and are responsible for producing keratin, a tough protein that helps provide strength and waterproofing to the skin.
What pigment is phagocytized by keratinocytes?
Melanocytes phagocytize melanin. First, melanocytes which are present in the lowest or basal layer of the epidermis, produce the pigment melanin. The melanin forms granules called melanosomes. After the keratinocytes take up the pigment, it clusters around the keratinocyte nucleus on the superficial side. This protects the DNA in the keratinocyte nucleus from damage due to UV radiation.
What granules extruded from the keratinocytes prevent water loss by diffusion through the epidermis?
A type of keratinocyte, the stratum granulosum - which is comprised of one to three layers of flattened cells - produces kerato-hyalin, present as small granules.
What are the formats of Keratinocyte Growth Medium?
• Basal Medium - contains no growth factors cytokines, or supplements• Supplement Kit - growth factors, cytokines, and supplements• Medium Kit - basal medium and Supplement Kit packaged together
Why structures develop as downgrowths of the stratum basale?
Structures develop as downgrowths of the stratum basale because this layer contains proliferative keratinocyte stem cells that continuously divide and differentiate. As these cells migrate downward, they can form various structures, such as hair follicles and glands, which are crucial for the skin's function and integrity. The interaction between these downgrowths and the surrounding mesenchymal tissue also influences their development and specialization. This dynamic growth process is essential for skin regeneration and repair.
What does LKC stand for in blood test?
leukocytes
