Integumentary System- weight and area - 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? - Answer: The
integument is made up of two parts
1. Cutaneous membrane (skin)
2. Accessory structures
Describe the Cutaneous Membrane - Answer: consist of two
components:
Outer epidermis
Superficial epithelium (epithelial tissues)
Inner dermis
Connective tissues
Accessory Structure - 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? - 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? - 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? - 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
PEMPD
Describe the Epidermis - 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 - Answer: Covers most of the body
, Has four layers of keratinocytes
Thick skin: location and layers - 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 - 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? - 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
