BSC 2085 Exam 2 Questions With
Clear Solutions 100% Pass
Integumentary System- weight and area - CORRECT ANSWER-Is the largest
system of the body
16% of body weight
1.5 to 2 m2 in area
How many parts makeup the integumentary system? - CORRECT ANSWER-The
integument is made up of two parts
1. Cutaneous membrane (skin)
2. Accessory structures
Describe the Cutaneous Membrane - CORRECT ANSWER-consist of two
components:
Outer epidermis
Superficial epithelium (epithelial tissues)
Inner dermis
Connective tissues
,Accessory Structure - CORRECT ANSWER-Originate in the dermis
Extend through the epidermis to skin surface. Includes:
Hair, Nails, Multicellular exocrine glands
What Systems are connected to the Integumentary system? - CORRECT
ANSWER-Cardiovascular system- By blood vessels in the dermis
Nervous system- By sensory receptors that detect stimuli for pain, touch, and
temperature
Is the hypodermis part of the Integumentary system? - CORRECT ANSWER-No,
Located below the dermis
-Composed of loose connective tissue: separates integument from the deep fascia
around organs
- Location of hypodermic injections
5 main functions of the Integumentary System? - CORRECT ANSWER-1.
Protection of underlying tissues and organs
2. Excretion of salts, water, and organic wastes (glands)
3. Maintenance of body temperature (insulation and evaporation)
4. Production of melanin, keratin, vitamin D3, and storage of lipids
5. Detection of touch, pressure, pain, and temperature

,Describe the Epidermis - CORRECT ANSWER-Is avascular stratified squamous
epithelium
Nutrients and oxygen diffuse from capillaries in the dermis
Dominated by keratinocytes (most abundant type of epithelial cells) -contain large
amounts of the protein keratin
Thin skin: location and layers - CORRECT ANSWER-Covers most of the body
Has four layers of keratinocytes
Thick skin: location and layers - CORRECT ANSWER-Covers the palms of the
hands and soles of the feet
Has five layers of keratinocytes
What are the 5 strata of keratinocytes in thick skin - CORRECT ANSWER-1.
Stratum basale
2. Stratum spinosum
3.Stratum granulosum
4. Stratum lucidum (missing in thin skin)
5.Stratum corneum
Bottom to top
What is the Stratum Basale? - CORRECT ANSWER--Is attached to basement
membrane by hemidesmosomes
, -Forms a strong bond between epidermis and dermis
-Forms epidermal ridges (basis of fingerprints)
-Dermal papillae (tiny mounds)- projections from the dermis-Increase the area of
basement membrane and ttrengthen attachment between epidermis and dermis
-Has many basal cells, or germinative cells
What determines fingerprints? - CORRECT ANSWER-Determined by genetics
and
uterine environment during fetal development.
Do identical twins have the same fingerprints? - CORRECT ANSWER-No
What are specialized cells of Stratum Basale? - CORRECT ANSWER-1. Merkel
cells- specialized epithelial tactile cells
Found in hairless skin
Respond to touch (trigger nervous system)
2. Melanocytes
Contain the pigment melanin
Scattered throughout stratum basale
What is the Stratum Spinosum? - CORRECT ANSWER-"the "spiny layer"
-Produced by division of stratum basale
