Integumentary system Flashcards
Consists of cells that look like granules. Almost dead and undergo a change into cells of the more superficial layer
Stratum granulosum
Form a fine branching pattern in connective tissue that helps line the bundles of collagen fibers
Reticulum fibers
Deeper layer of the dermis
Reticular
70% of the dry weight of the skin and gives it strength, form, and flexibility
collagen
Prtotien that has elastic properties and helps give the skin its resiliency.
Elastin
Very thin, nearly invisible layer of clear cells
Stratum lucidum
directly beneath the epidermis
Papillary
Continuation of the dermis
Subcutaneous
Egg shaped preceptors sensative to vibration and pressure (deepest)
Pacinian corpuscles
receptors sensative to temperature, light touch, and light pressure
Free nerve endings
Pain receptors that are sensative to chemical released by damaged cells
nociceptors
Respiratory sensative to deep pressure and tissue distortion
Ruffini corpuscles
Receptors sensative to vibration and light touch
Meissner corpuscles
Receptors sensative to light touch, and are highly concentrated in the finger tips, lips, and external genitalia
Merkel discs
Gland that connects to the hair follicles and produce sebum
Sebaceous
Glands that respond to elevate body temperatures resulting from environmental conditions or physical activity.
Sudoriferous
Outer most layer of the skin
Epidermis
Sensitivity that certain people develop to normally harmless substance
Allergies
Inflammatory condition of the skin that come in various forms such as scales, vesicles, or papules
Dermatitis
congenital absences of melanin pigment in the body that effects the color of the skin, hair, and eyes
Albinism
reacts to cold or emotional stimuli. goosebumps
Arrector pili
Protection, heat regulation, Secreation and excretion, sensation, absorption, and synthesis of vitamin D
Functions of the Integumaentary system
Fungal condition that thrive in moist environment
Athletes foot
