4th 20 Flashcards
what type of pigment is Yellow, brown or black pigments
What type of pigment is Orange-yellow pigment from some vegetables
what is the Red coloring from blood cells in dermis capillaries and its Oxygen content determines the extent of red coloring
What type of pigment that is Low in oxygen content and creates abluish appearance
Melanin
Carotene
Hemoglobin
Cyanosis
This is a Pigment produced by melanocytes
Melanin (Amount of melanin produced depends upon genetic and exposure to sunlight)
What are the two layers of dermis
Papillary Layer
Reticular Layer
this is a Projections called dermal papillae, Pain receptors, and Capillary loops
This is where Blood vessels, Glands, Nerve receptors are located
Papillary Layer
Reticular layer
What are the two types of Sweat Glands
Eccrine and apocrine
This Produce oil, Lubricant for skin, and Kills bacteria
Sebaceous Glands
(glands are activated at puberty)
What are the two types of Sweat Glands
Eccrine (Open via duct to pore on skin surface)
and apocrine (Ducts empty into hair follicles)
What is the anatomy of hair
Central Medulla
Cortex (it surrounds the medulla)
Cuticle (on outside of cortex)
Structure of the Hair
Hair follicle
Arrector Pili
Sebaceous Gland
Sweat Gland
(just in case lang this card)
This is a small band of SMOOTH MUSCLE that connects the hair follicle to the connective tissue of the basement membrane
Arrector Pili
A shaft or opening on the surface of the skin through which hair grows.
Hair Follicle
microscopic glands found in your hair follicles that SECRETE SEBUM
Sebaceous Gland
(Sebum is an oily substance that protects your skin from drying out)
Scale-like modifications of the epidermis and is heavily keratinized
Nails
this extends beneath the nail bed and Responsible for growth
Stratum basale
Nail Structure
Free edge
Body
Root of nail
Eponychium
(Just in case)
proximal nail fold that projects onto
the nail body
Eponychium
What degree of burn is:
Only epidermis is damaged and Skin is red and swollen
Destroys entire skin layer and Burn is gray-white or black
Epidermis and upper dermis are damaged and Skin is red with blisters
1st degree
3rd degree
2nd degree
Cancer are abnormal cell mass, What are the two types of Cancers
Benign (Does not spread)
Malignant (moves to other parts of the body)
(Skin cancer is the most common type of cancer)
this is a cancer that is Least malignant and Most common type that Arises from statum basale
This is a cancer that Arises from stratum spinosum and Metastasizes to lymph nodes and Early removal allows a good chance of cure
This cancer is Most deadly of skin cancers and Cancer of melanocytes it Metastasizes (moves) rapidly to lymph and blood vessels
Basal Cell Carcinoma
Squamous cell carcinoma
Malignant melanoma
The detection of malignant melanoma uses ABCD rule, What is the ABCD rule
A = Asymmetry
Two sides of pigmented mole do not match
B = Border irregularity
Borders of mole are not smooth
C = Color
Different colors in pigmented area
D = Diameter
Spot is larger then 6 mm in diameter
