What are Striae?

Back 8

stetch marks, torn collagen. Occurs in dermis

Front 9

What do we call decreased flexibility and thickness of dermis?

Back 9

Wrinkles Occurs in dermis

Front 10

What are Cleavage Lines?

Back 10

Orientation of collagen bundles. Occurs in dermis

Front 11

Explain the function, and structure of the hypodermis (Subcutaneous) or (Superficial Fascia).

Back 11

Structure
-Areolar and adipose connective tissue
-Not considered part of the integument
Functions
-ALLOWS MOVEMENT
-Anchors skin to underlying structures
-Thermal insulation
-Energy reservoir

Front 12

What are the structures of nails?

Back 12

-Nail matrix
-Lunula
-Cuticle
-Free edge

Front 13

What are the 3 types of hair?

Back 13

Three Types
-Lanugo (fetal)
-Vellus (fine hair on most of the body)
-Terminal (head, pubic region, armpit, male facial hair)

Front 14

What are the Functions, Structure, and Growth of Hair?

Back 14

Functions
-Protection
-Sense touch
-Reduce heat loss
Structure
-Follicle, root and shaft
-Contains keratin
-Arrector pili muscle
Growth
-Rate of hair growth is about 2 mm/week
-Growth cycles:
-Active phase (2-7 years)
-Dormant phase (3-4 months)

Front 15

What are types of Baldness?

Back 15

-Alopecia (hair thinning)
-Diffuse Hair loss
-Male Pattern Baldness
-Genetic influences
-Hormonal influences
-Testosterone causes terminal hari to be replaced by vellus hair

Front 16

What are the Exocrine Glands in Skin?

Back 16

Sebaceous (oil) glands
-Produce Sebum
Sudoriferous (sweat) glands
-Merocrine (eccrine) glands
-Most numerous
-Produce watery sweat
-Apocrine glands
-Axillary, nipple, anal and genital areas
-Produce viscous sweat

Back 17

Plugged sebaceous duct

Front 18

-Third Degree damages entire epidermis and dermis

Front 19

What are the types of Skin Cancer?

Back 19

-Basal Cell Carcinoma
-Most common type
-Least dangerous type
-Originates in stratum basale
-Squamous Cell Carcinoma
-Arises from keratinocytes
-Malignant Melanoma
-Most deadly type
-Arises from melanocytes (usually a pre-existing mole)
-Early detection is crucial

Front 20

What is the ABCD rule?

Back 20

A=Asymmetry (One half of mole doesn’t match with the other)
B=Border (Edges notched, irregular, blurred or ragged)
C=Color (Not uniform, different shades)
D=Diameter (Larger than ¼ inch)
