Anatomy #3
What is an advantage of having sebaceous glands?
They keep skin and hair soft and conditioned
Where are epidermal ridges found?
dermis
What type of bone is the on showing in the picture?
irregular
look at the image. What view of the body does #3 represents?
superior
What are lines of cleavage?
"tension lines" in the skin indicate the predominant direction of underlying collagen fibers.
What type of burn will kill some cells in the epidermis which will be replaced by mitosis?
1st degree burn
What type of burn will kill all cells in the epidermis and some cells in the dermis layer. Self regeneration still occurs.
2nd degree burn
What type of burn destroy the epidermis and dermis, also damages the underlying bones, muscles, and tendons? There is no sensation in the area since the nerve endings are destroyed. Skin graft is necessary at this point because the skin will not regenerate by itself.
3rd degree burn
Skin functions/ characteristics
All are correct
What is an disadvantage of having sebaceous glands?
All are correct
The glands we find mainly in the pubic area and in the dermis are
Apocrine sweat glands
Why is it important to know the directions of the lines of cleavage if you are a surgeon?
Cuts in surgery are usually made parallel to these lines to help healing and leads to optimal scar formation.
Choose the correct statement about the Epidermal ridges.
Every human being has a unique pattern of ridges (fingerprints and footprints).
What are the functions of the epidermal ridges?
Increase friction to help grip objects
What do we call a tubelike passageway in the body?
Meatus
Why are sebaceous glands important?
Protect against bacteria
What are the small oil-producing glands present in our skin?Usually attached to hair follicles and release a fatty substance, sebum, into the follicular duct and thence to the surface of the skin.
Sebaceous glands

appendicular skeleton
The part of the skeleton that includes the skull and spinal column and sternum and ribs
axial skeleton
What are epidermal ridges?
downward waves of epidermis What makes fingerprints

The glands we find mainly in the dermis are
merocrine sweat glands
What do apocrine sweat glands that produce when come in contact with bacteria on the skin?
