What is a characteristic of the tissue layers that make up the epidermis?
• They generate most of the heat that is produced in the body.
• They contain many of the sensory cells found within the skin.
• They serve as a passageway for the skin’s blood supply.
• They range from dead cells on the top to actively dividing cells at the bottom.
1. B - 206
2. C - producing movement of the body
3. C - They range from dead cells on the top to actively dividing cells at the bottom
4. A - abduction and adduction
I took the quick check so yes these answers are correct.
They range from dead cells on the top to actively dividing cells at the bottom.
The characteristic of the tissue layers that make up the epidermis is that they range from dead cells on the top to actively dividing cells at the bottom.
To arrive at this answer, we need to understand the structure of the epidermis, which is the outermost layer of the skin. The epidermis is composed of several layers of cells called keratinocytes. These cells undergo a process called keratinization, where they produce a tough protein called keratin and eventually die, forming a protective layer on the skin's surface.
The epidermis has several distinct layers, including the stratum corneum (the outermost layer), the stratum granulosum, the stratum spinosum, and the stratum basale (the innermost layer). The cells in the stratum basale are actively dividing, constantly replenishing the upper layers of the epidermis. As the cells move towards the surface, they undergo changes and eventually become dead cells in the stratum corneum.
Therefore, the epidermis consists of layers with dead cells on the top and actively dividing cells at the bottom, making it a characteristic of the tissue layers that make up the epidermis.
