Integumentary System Flashcards
Name the 3 Structure of Human Skin
- Epidermis
- Dermis
- Hypodermis
What are the 4 stages of the Regenerative Process?
- Hemostasis
- Inflammation
- Proliferative
4, Remodeling
What are the 4 main functions of skin?
- Protection
- Sensation
- Thermoregulation
- Vitamin D synthesis
Where are there NO Eccrine Sweat Glands?
Lips, external ear canal, nail beds, glands, penis, labia minora
What is the purpose of Eccrine Sweat Glands?
- Cooling through evaporation
- Ion + Nitrogen waste excreation
- Antimicrobial
Where can you find Apocrine Sweat Glands?
Axillary, perineum, labia majora, scrotum, nipples, areola
What is the function of Apocrine Glands?
To produce pheromones and communication
Where can you find the Sebaccous Glands?
Everywhere except the palms and soles
What is the purpose of the Sebaceous Glands?
To produce sebum, to lubricate, and waterproof hair
What is the epidermis
outer layer of skin
What is the dermis
the second layer of skin which contains nerves, glands, and veins
what is the hypodermis
connects the skin to underlying fascia
what are the functions of the integumentary system?
protection, thermoregulation, vitamin d synthesis
define tissue
a group of many similar cells that work together to perform a specific function
atoms -> molecules -> cells -> tissue
name 4 types of tissue
epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
what is the epithelial tissue
lining of the GI tract organs & other hollow organs
what is connective tissue
fat & soft padding tissue, bone, and tendon
*connect
what is muscle tissue
cardiac muscles, smooth muscles, and skeletal muscles
*contracts
what is nervous tissue
brain, spinal cord, and nerves
*signal
describe tissue membrane
a thin layer or sheet of cells that covers the outside of the body (skin), the organs, internal passageways that lead the exterior of the body, and the lining of the moveable joint cavities.
what is the mucus membrane located
lines the digestive, respiratory, urinary, and reproductive tracts
where is the serous membrane located
lines body cavity closed off to external of the body
where is a cutaneous membrane located
covers the body surface (skin)
where is the synovial membrane
lines the joint cavities & produce the inner fluid
where are tissue membranes found
anywhere the body needs lining or covering
