Lesson 7 - INTEGUMENTARY SYSTEM Flashcards
hypodermis is NOT part of the integumentary system
true, it is located below the dermis
the largest organ system of the body____
(16% of body weight & 1.5 to m2 in area)
the integument
the integument is made up of 2 parts: _____ and ____
cutaneous membrane (skin)
accessory structures (nails, hair, and glands)
consists of 2 components: outer epidermis and inner dermis
cutaneous membrane
superficial epithelium (epithelial tissues)
outer epidermis (cutaneous membrane)
connective tissues
inner dermis (inferior/underneath the epidermis)
originate in the dermis
accessory structures
accessory structures extend through the epidermis to ____ ____
skin surface
accessory structures include:
hair, nails, and multicellular exocrine glands (sweat and sebaceous glands)
the integumentary system is connected to:
cardiovascular system (by blood vessels in the dermis)
nervous system (by sensory receptors that detect stimuli for pain, touch, and temp)
not considered part of the integumentary system
hypodermis (superficial fascia or subcutaneous layer)
located below the dermis
composed of loose connective tissue - separates integument from the deep fascia
-location of hypodermic/subcutaneous injections
hypodermis
- protection* of underlying tissues and organs
- excretion* of salts, water, and organic wastes (glands)
- maintenance* of body temperature (insulation and evaporation)
- production* of melanin, keratin, vitamin D3, and storage of lipids
- detection* of touch, pressure, pain, and temperature
5 main functions of skin
cutaneous membrane and accessory structures of the integumentary system
