Do Squamous cell carcinoma involve dermal cells?

No, they involve superficial epidermal cells


Which type of dermal cell has more chloroplasts than any other dermal cells because it has greater energy needs?

Guard cells have more chloroplasts than any other dermal cells because they need energy to facilitate the opening and closing of stomata for gas exchange and water regulation in plants.


What tissue associated with the skin and underlying tissues contains many cells that fight infection What are these cells called what process do they use to rid the body of organisms?

Our skin has two layers: (1) Epidermal layer and (2) Dermal layer.Micro-organisms that penetrate through the epidermal layer is trapped in dermal layer which has WBC's, mast cells that fight antigen.Dermal layer has two parts, papillary layer and dermis. Other processes in the dermis then gets rid of any waste collected in the papillary of epidermal layer.


How do snakes adapt to the land?

The epidermal skin cells in the gastroventricular layer of their epiglottis is financially suited and abdicate the velocities of the dermal xylem. This enables them to live on land.


What cells are epidermal cells?

Epidermal cells are a type of skin cell that form the outermost layer of the skin. They protect the body from environmental damage and help regulate water loss. These cells can include keratinocytes, melanocytes, Langerhans cells, and Merkel cells.


What cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?

Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.


Do epidermal cells from petunia stain with phloroglucinol?

No, epidermal cells from petunia do not stain with phloroglucinol. Phloroglucinol is typically used to stain lignin in plant tissues, not epidermal cells. The stain mainly reacts with lignin, which is absent in the epidermal cells.


The more superficial cells of the epidermis become less viable and die what factors account for this natural demise?

We skin cells are made, they are made in the deep layers of the skin, the dermal layer. This layer of the skin has blood supply, and cells that are in the dermal layer stay alive just fine. However, as cells in the upper layer, the epidermis, die; the skin cells in the dermal layer gets, pushed up into the epidermal layer. In this layer of the skin, there is no blood supply. However, nutrients are still passed from the blood rich dermal cells to the epidermal cells. The problem occurs when the epidermal cell is pushed right to the top of the epidermal layer, where there is no blood supply and it is too far away from the dermal layer to get nutrients vie osmosis. The cells in the upper epidermis get no nutrients and therefore die. Epidermal cells also die, ironically, because of the substances that they produce, keratin. Keratin is secreted by all skin cells to make the skin tough, durable and waterproof. However the build up of this keratin in the cell, leaks out in the extracellular space (the area outside the cell) and starts to breakdown the membranes of the cells around them and the cells essentially end up killing each other.Epidermal cells die because of the loss of nutrient supply as they get closer and closer to the surface of the skin, and the buildup of keratin inside them that leaks out into the area outside the cells.Read more: Why_do_epidermal_cells_die


What is the name given to the pocket of epidermal and dermal cells that the hair grows within?

That would be the follicle. The hair follicle is a small tubular cavity containing the root of a hair; small muscles and sebaceous glands are associated with hair follicles.A mature hair follicle contains a bulb holding the dermal papilla cells, a hair shaft extending from the bulb through to the outer exterior of the epidermis, and a dermal sheath which provides an external covering of tissue around the bulb and along the length of the follicle.The hair follicle extends through the dermis, a hypodermis (a loose layer of connective tissue below the dermis), and a fat (or adipose) layer. In adults, molecular signals between the dermal papilla and the epidermal component of a follicle cause the hair to enter an active growth phase from an inactive phase.

An excess build up off epidermal cells is called?

An excess build-up of epidermal cells is called hyperkeratosis. This condition can lead to thickening of the skin and formation of calluses or corns in response to friction or pressure. Treatment may involve moisturizing creams or exfoliation to help slough off the excess cells.
