Anatomy
ANATOMY
What is the study of the functions and activities performed by the body structures?
Physiology
ANATOMY
What is the study of the structures and composition of tissue?
Histology
ANATOMY
What is the basic unit of all living things?
Cell
ANATOMY
Part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell
Cell Membrane
ANATOMY
The dense, active protoplasm found in the center of the cell. Plays an important role in reproduction and metabolism.
Nucleus
ANATOMY
Takes in nutrients, breaks them down, and create energy for the cell.
Mitochondria
ANATOMY
The cell responsible for producing collagen and elastin
Fibroblast
ANATOMY
Hormones that stimulate skin cells to reproduce and heal
EFGs (epidermal growth factor)
LAYERS OF THE SKIN
What are the three main components (layers) of the skin?
- Epidermis
- Dermis
- Hypodermis (subcutaneous layer)
LAYERS OF THE SKIN
What is the outermost layer of the skin?
Epidermis
LAYERS OF THE SKIN
Layer comprised of connective tissue made of collagen protein and elastin fibers
Dermis
LAYERS OF THE SKIN
Which layer’s function is to supply the skin with oxygen and nutrients through blood vessel and lymphatic channels?
Dermis
LAYERS OF THE SKIN
What are the different layers of the epidermis? (superficial to deep)
- Stratum Corneum
- Stratum Lucidum
- Stratum Granulosum
- Stratum Spinosum
- Stratum Germinativum
LAYERS OF THE SKIN
The basal layer located above the dermis where stem cells undergo cell division (mitosis)
Stratum Germinativum
LAYERS OF THE SKIN
The ‘horny layer”, top outermost layer of the epidermis where desquamation of keratinocytes occurs
Stratum Corneum
LAYERS OF THE SKIN
Which layer of the skin do estheticians work with extensively?
Stratum Corneum
LAYERS OF THE SKIN
What is the average cell turnover rates for the average adult?
28 days
LAYERS OF THE SKIN
Thin, clear layer of dead skin cells. Thickest on the palms of the hands and soles of the feet (forms finger/footprints)
Stratum Lucidum
LAYERS OF THE SKIN
What are the layers of the dermis?
- Papillary
- Reticular
LAYERS OF THE SKIN
Which of the dermal layers connects the dermis to the epidermis?
Papillary Layer
LAYERS OF THE SKIN
Which layer of the skin is known as “true skin”?
Dermis
LAYERS OF THE SKIN
The denser, deeper layer of the dermis; comprised mainly of collagen and elastin
Reticular Layer
LAYERS OF THE SKIN
Which is the thickest layer of skin?
Dermis (25x thicker than epidermis)
