Question 25

Functions of Integumentary System (10)

Answer 25

Insulates and cushions the deeper body organs protects from mechanical damage protect thermal damage protect chemical damage protects from UV radiation Synthesizes vitamin D Prevents water loss (desiccation ) Aids in body heat lost or heat retention Aids in excretion of urea Bacteria damage Has receptors that temperature, pain, touch, and presion

Question 26

Answer 26

Epidermis | Dermis

Question 27

essentially is adipose (fat) tissue

Answer 27

hypodermis (subcutaneous tissue)

Question 28

It is not considered part of the skin, but it does anchor the skin to underlying organs and provides a site for nutrient storage. responsible for the curves that are more a part of a woman’s anatomy

Answer 28

Hypodermis

Question 29

Most cells of the epidermis are

Answer 29

keratinocytes

Question 30

keratinocytes

Answer 30

produce keratin ( fibrous protein)

These kerat- inocytes are connected by ____through- out the epidermis

Answer 31

desmosomes

Question 32

The epidermis is composed of up to five layers:

Answer 32

``` basale spinosum granulosum lucidum corneum ```

Question 33

The deepest cell layer of the epidermis lies closest to the dermis and is connected to it along a wavy border that resembles corrugated cardboard.

Answer 33

basale

Question 34

Cells contain thick bundles of intermediate filaments made of pre-keratin.

Answer 34

spinosum

Question 35

they become flatter and increasingly keratinized. Cells are flattened, organelles are deteriorating; cytoplasm full of granules.

Answer 35

granulosum

Question 36

Cells are dead, flat membranous sacs filled with keratin. Glycolipids in extracellular space make skin water resistant.

Answer 36

corneum

Answer 41

the papillary | reticular areas

Question 42

associates with epidermis through dermal papillae and epidermal ridges loose connective tissue made up of fine collagen and elastic fibers supports epidermis and regular body temperature

Answer 42

papillary layer

Question 43

deepest skin layer contains dense irregular connective tissue, as well as blood vessels, sweat and oil glands, and deep pressure receptors called lamellar corpuscles.

Answer 43
