Sebaceous glands
sebaceous gland, small oil-producing gland present in the skin of mammals. Sebaceous glands are usually attached to hair follicles and release a fatty substance, sebum, into the follicular duct and thence to the surface of the skin.

What substance is manufactures in the skin but is not a secretion to play a role elsewhere in the body?
Region where melanocytes are most likely to be found. Accounts for most of the epidermis. What substance is manufactured in the skin (but is not a secretion) to play a role elsewhere in the body? The skin is the site of vitamin D synthesis for the body.
Why is the secretion of sebum important?
Sebum lubricates the skin to protect against friction and makes it more impervious to moisture. Furthermore, the sebaceous gland transports antioxidants in and on the skin and exhibits a natural light protective activity.
How does skin function in secretion?
The skin perspires by producing moisture through secretions of the sudoriferous glands. The evaporation of this moisture has a cooling effect on the body. The dilation/expansion of capillaries causes the reduction of body surface heat through radiation [skin gets flush].
What secretion contains cell fragments?
Sebum is an oily mixture of lipids, cholesterol, and cell fragments. Dermis 5. The epidermis provides mechanical strength to the skin.
Why is secretion of sebum important?
The normal function of sebaceous glands is to produce and secrete sebum, a group of complex oils including triglycerides and fatty acid breakdown products, wax esters, squalene, cholesterol esters and cholesterol. Sebum lubricates the skin to protect against friction and makes it more impervious to moisture.
What is hair sebum?
Well, per the Cleveland Clinic, sebum is oil produced by sebaceous or oil glands. These oil glands are located on your scalp, and they produce oil to hydrate your hair just as the oil glands on other areas of skin do for the rest of your body.
