How many mitochondria does a skin cell have?
Cells that require the most energy contain the most energy generating mitochondria. The cells of the brain, the skeletal muscle and heart muscle, and the eye contain the highest number of mitochondria (as many as 10,000 per cell) while the skin cells, which do not require much energy, contain only a few hundred of them.
What of the following is a vital function of the skin?
Its main function is protection.
Each of the structures that make up the skin has one or more functions, which play a vital role in maintaining good health. One of the primary purposes of the skin is to provide a flexible, protective shield between us and the outside world. This is made possible by the layers of dead, flattened epithelial cells which prevent microorganisms and chemicals from entering the body, and by the waterproofing effect of the keratin, fats and oils.
The major function of skin is protection from injury and dehydration. It also keeps pathogens out of your body and helps maintain temperature.
blood vessels, lymphatic vessels, and connective tissue
The root word "necro" means dead. So the necrotic skin is black because it has no blood supply and is dead.
Which is NOT a function of sweat?
Keeping you warm is not a function of sweat. Sweat protects a person from becoming overheated on extremely hot days.
Protects the inside of the of the body. Covers organs such as the small intestines. Provides warmth from the body onto the surface. Covers both muscle tissue and fat tissues and bones. Can heal itsself on the surface of the skin (The red thing you get and when you take it off it bleeds).
When does the part of the brain responsible for planning and analyzing mature?
That would be during Adolescence. C:
What is major factor accounting for the waterproof nature of skin?
of the stratum granulosum, and contain a waterproof glycolipid that is excreted into extracellular space helping to slow water loss across the epidermis.
Layer directly deep to the skin?
The layer directly beneath the skin (epidermis) is the dermis. The dermis contains connective tissue, blood vessels, hair follicles, and nerve endings, providing structural support and nourishment to the skin. It is divided into two layers: the papillary dermis and the reticular dermis, each playing a vital role in skin health and function.
How do the integumentary and muscular systems work together?
The integumentary system covers and protects the muscular system. If we didn't have this protection, the muscles would be damaged be the external environment to the point of not being able to function properly. The muscular system works to move the skin to help with certain functions, such as the elevation of body hair when you're cold.
Sebaceous glands are found in the dermis and are closely associated with hair follicles.
WEll your body is a bunch of organs and 1 of em keeps your skin cells alive
Is the stratum corneum made up of cells that are cuboidal in shape?
No, the stratum corneum is made up of squamous (tile-like) cells, not cuboidal cells.
Why is the epidermis keratinized and not non-keratinized?
In this case, the most apical layers (exterior) of cells are dead and lose their nucleus and cytoplasm, instead contain a tough, resistant protein called keratin. This specialization makes the epithelium waterproof, so is found in the mammalian skin.
Is the dermis the outermost layer of the skin?
The epidermis is the superficial layer of the skin. The Integumentary System (skin) consists of two main layers the epidermis and dermis. The dermis is deeper into the body (internal), thus the deep layer of the skin, not the superficial layer. epidermis
No the epidermis is. The dermis is the innermost layer. There are only 2 layers of the skin.
No the epidermis is. The dermis is the innermost layer. There are only 2 layers of the skin. no,dermis is not upper layer of skin. epidermis is superficial one,dermis is below epidermis.
What process formed the new skin underneath the pealing skin?
regeneration regeneration or dominant trait
