Which structure of the hair follicle is made of shingle-like layers of cells?
The cuticle is a tightly formed structure made of shingle-like overlapping scales.
Does the stratum corneum consist of layers of cornified dead cells?
Yes, the stratum corneum consists of layers of cornified dead cells. They are strong, full of keratin, and contain no nucleus.
Where is the main part of the sweat gland situated?
The main part of the sweat gland is situated in the dermis layer of the skin, however the tubes reach the epidermis/outer layers of the skin. Sweat glands are found all over human body (around2-5 mill), but are most abdundant in palms, feet and forehead. There are two types of sweat glands: eccrine and apocrine glands and are made up of epithelium tissue, surrounded by a network of capillaries
Skin cells on the surface are dead and therefore do not contain any functional organelles. The hypodermal layer (the layer beneath the visible skin) has active cells and contains ribosomes.
Does blubber help to prevent water loss from the body?
Blubber, or subcutaneous fat, helps prevent heat loss from the body. Keratin in the epidermis helps prevent water loss from the body.
How does the environment affect the epidermis?
Lets think of the environment interacting with your epidemic:
- If it is sunny day (especially at a mountainous elevation) your skin will tan first then burn due to the ultraviolet light
- If the local bugs are out (mosquitos, black flies and such) they will dine on you through your epidermis.
- They may cause you to run into poison ivy or other nasty toxic plants or through thorn bushes. Your epidermis will suffer.
- Falling down a cliff as the next of your adventures will abrade the epidermis from your body.
- At the bottom of the cliff, as you lie there, moulds and fungus will begin to gnaw on you before the big scavengers start to remove the remainder of your epidermis with a lot of the sub epidermal tissue.
- If however you fall into a river the fish will do the same.
melanocytes produces melanin (pigment you're talking about). They are located in the most bottom layer of the epidermis (stratum basale).
Is the dermis part of the circulatory system?
The dermis is one of the layers of the skin. It is part of the integumentary system.
What organ system includes the epidermis dermis oil and sweat glands?
The integumentary system (skin) contains the epidermis, dermis, oil glands, and sweat glands.
What organ system controls the activity of eccrine sweat glands?
The nervous system.
Sweating is regulated by the sympathetic division of the autonomic nervous system, over which we have little control. Its major role is to prevent overheating of the body.
How many eccrine glands are in your body?
- There are about 2 to 3 million eccrine sweat glands all over your body.
