Integumentary System Questions With
Answers.
Integumentary System - ANSWER- Skin and accessory structures: glands, hair, and
nails.
The Epidermis - ANSWER- contains no blood vessels (avascular).
Dermis - ANSWER- connective tissue portion the cutaneous membranes, contains
many blood vessels, nerve endings and glands
The epidermis outermost cells are constantly lost through - ANSWER- wear and tear
The cells in the epidermis are nourished by - ANSWER- capillaries in the underlying
dermis.
New epidermal cells are produced from - ANSWER- stem cells in the deepest layer,
which is closest to the dermis.
The cells in the deepest layer of epidermis is called - ANSWER- stratum basale
Stratum Basale are constantly - ANSWER- dividing and producing new cells, which are
then pushed upward toward the skin surface.
By the time epidermal cells from Stratum Basale approach surface, they have become
flat and keratinized, or cornified, forming the uppermost layer of the epidermis, -
ANSWER- Stratum Corneum
The Stratum Corneum is a - ANSWER- protective layer and is more prominent in thick
skin than in thin skin.
Melanin - ANSWER- dark pigment that colors skin and protects it from sunlight's harmful
rays.
-produced by some cells in the deepest layer of epidermis.
Melanocytes - ANSWER- Cells that produce pigment (melanin)
The Dermis has - ANSWER- a frame work of dense irregular connective tissue and is
well supplied with blood vessels and nerves.
, The skin's accessory structures, sweat glands, oil glands, and the hair are located in -
ANSWER- the dermis and may extend into the subcutaneous layer under the skin
Dermal Papillae - ANSWER- portions of the dermis extending upwards into the
epidermis, allowing blood vessels to get closer to the superficial cells.
Dermal papillae can be - ANSWER- seen on the surface of thick skin, such as at the
tips of fingers and toes
-they form a distinct patter of ridges that help to prevent slipping.
The subcutaneous layer consists of _____________________ and variable amounts of
_____________________. - ANSWER- 1. areolar connective tissue
2. adipose tissue
The adipose tissue in subcutaneous layer serves as - ANSWER- insulation and as a
reserve energy supply.
This subcutaneous layer is also - ANSWER- rich in nerves and nerve endings, including
those that supply nerve impulses to and from the dermis and epidermis.
Accessory structures of the skin - ANSWER- sebaceous (oil) gland, sudoriferous
(sweat) glands, hair, nails,
Sebaceous (Oil) glands are - ANSWER- saclike in structure, and has an oily secretion
called sebum.
Sebum - ANSWER- lubricates the skin and hair and prevents drying.
The ducts of the sebaceous glands... - ANSWER- open into the hair follicles
Babies are born with a covering produced by sebaceous glands that resemble cream
cheese - ANSWER- Vernix Caseosa
Sudiferous glands (sweat glands) - ANSWER- are coiled, tubelike structures located in
the dermis and subcutaneous tissue.
Most of the sudoriferous glands function to - ANSWER- cool the body. They release
sweat, that draws heat from the skin as the moisture evaporates at surface.
The Eccrine type sweat glands are - ANSWER- distributed throughout the forehead,
feet and hands and responds by negative feedback.
The Apocrine sweat glands are located mainly in - ANSWER- the armpits(axillae) and
groin area
