What's the largest organ in the body? - CORRECT ANSWER-skin - accounts for 7
percent body weight
Hypodermis (subcutaneous layer) - CORRECT ANSWER-Deep to the dermis; not
technically part of the skin; made of adipose tissue; helps insulate
Dermis - CORRECT ANSWER-Deep to the epidermis
Muscle - CORRECT ANSWER-lies deep to the skin
What is needed to make calcium - CORRECT ANSWER-Vitamin D
Epidermis - CORRECT ANSWER-is primarily stratified squamous, it is the first line of
defense.
What are the two main layers of the integumentary system - CORRECT ANSWER-Skin
and hypodermis
What are the functions of the integumentary system - CORRECT ANSWER--protection
-Body temp regulation
- Excertion
- Production of vitamin D
-sensory reception
Skin is only composed of what - CORRECT ANSWER-Epidermis and dermis
Most superficial layer of skin - CORRECT ANSWER-epidermis
Dermis - CORRECT ANSWER-Is primarily composed of collagen fiber and Aereolar
connective tissue
Hypodermis (subcutaneous layer) - CORRECT ANSWER-Composed of adipose tissue
and some areolar connective tissue; functions as a site for storage, shock absorber,
insulates deep tissue, and anchors skin to underlying tissues.
4 main cell types in epidermis - CORRECT ANSWER-1. Keratinocytes- most common,
tough fiber
2. Melanocytes- Make a pigment, skin color
3. Merkel cells (Tactile epithelial cells)- Aid in sensation of touch
, 4. Langerhans (Dendritic cells)- star shape, immune responses, patrol for pathogens
and will alert immune system.
The epidermis is composed of - CORRECT ANSWER-stratified squamous epithelium
what is the difference between thick and thin skin, where do you find them? -
CORRECT ANSWER-Thin skin- four layers(strata), very thin stratum corneum, covers
the rest of the body
Thick skin- five layers, a very thick stratum corneum, found on the palms of the hands
and soles of the feet.
layers of epidermis - CORRECT ANSWER-stratum corneum, stratum lucidum (only in
thick skin), stratum granulosum, stratum spinosum, stratum basale (stratum
geminativum)
Germinative cells - CORRECT ANSWER-Actively reproducing, differentiate to produce
male and female gametes, sperm and unfertilized eggs.
why are the hands thick skin - CORRECT ANSWER-for more protection
One type of cell basal to the stratum spinous is the - CORRECT ANSWER-Langerhan
cell
One difference between thick and thin skin - CORRECT ANSWER-relates to the
presence of stratum corneum
What is the function of the epidermal ridge and where is it located - CORRECT
ANSWER-located in the finger prints, it is for improving friction and gripping ability
Describe the two layers of the dermis, and what type of connective tissue do you find in
each - CORRECT ANSWER-Papillary layer- includes dermal papillae, superficial 20
percent of dermis
Recticular layer- deeper layer, 80 percent of thickness of dermis, it is a network of
collagen fibers, and had dense irregular connective tissue
What are lines of cleavage and why are they important - CORRECT ANSWER-they are
tension lines of collagen fibers and they are perpendicular to the deep muscle.
they are important because surgeons use them as guidelines to reduce scaring and
improve healing.
What is the subcutaneous layer? - CORRECT ANSWER-hypodermis - layer of
connective tissue (adipose and LCT) that binds the skin to underlying structures.
what three things contribute to Skin color - CORRECT ANSWER--Melanin- most
important pigment, made from tyrosine
-cartotene - yellowish pigment from carrots and tomatoes
