What is the term for:
- Protein that is the primary component of skin cells
- A hard version of this substance (blank) makes up nails and hair, while soft keratin makes up the skin
Keratin
What is the term for:
Chemical process by which cells change their shape, push older cells toward the surface; cells become flat, hard and eventually die, forming a dead layer of protein cells at the skin’s surface
Keratinization
What is the term for:
Harmful foreign substances
Antigens
What is the term for:
- Layer of skin immediately underlying the epidermis
- Also known as dermal layer, derma, corium, cutis or true skin; made up of the reticular and papillary layers
Dermis
What is the term for:
- A complex secretion containing a high percentage of fatty, oily substances
- Mixes with the secretion of the sweat glands and spreads over the surface of the skin
Sebum
What is the term for:
- Controlled by the nervous system of the body
- Each gland consists of a coiled base and tube-like duct opening on the surface of the skin to form sweat pore
- Control and regulate body temperatures
- Excrete waste products
- Help to maintain the acidic pH factor of the skin
Sudoriferous Glands
What is the term for:
Skin care product that protects the skin from UV rays or sun exposure
Sunscreen
What is the term for:
- Outermost protective layer of the skin
- Composed of five layers of cells
- Also known as cuticle or epidermal layer
Epidermis
What is the term for:
Cells that produce melanin, which are contained in melanosomes
Melanocytes
What is the term for:
- Oil glands that produce sebum; partially controlled by the nervous system
- Sac-like glands that are attached to hair follicles
- Cause oily skin and/or hair when an overabundance of sebum is produced by the glands
Sebaceous Glands
What is the term for:
Type of melanin that produces brown/black hair color
Eumelanin
What is the term for:
- Pigmented packets that contain melanin
- Produced by melanocytes
Melanosomes
What is the term for:
- Adipose (fatty) tissue below the dermal layer of the skin
- Protective cushion for the skin
- Acts as a shock absorber to protect the bones and helps support the delicate structures, such as blood vessels and nerve endings
Subcutaneous Layer (Tissue)
What is the term for:
A medical skin specialist
Dermatologist
What is the term for:
- A mixture of sebum from the sebaceous glands and moisture from the sweat glands that forms a protective barrier for the skin
- Keeps skin smooth, prevents bacteria, dirt and grime from entering the epidermis
- Helps maintain the hair and skin’s normal pH range of 4.5 to 5.5
Acid Mantle
What is the term for:
The six basic functions of the skin include sensation, heat regulation, absorption, protection, excretion and secretion
Skin Function
What is the term for:
- Consist of protein keratin and epithelial cells that cover and protect the inside of the body
- Also called corneocytes
Keratinocytes
