What does the Integumentary System consist of? correct answers The Integumentary System
consists of skin and accessory structures such as hair, nails, and glands
Name the functions of the skin correct answers 1. Regulation of the Body Temperature
2. Protection
3. Sensation
4. Excretion
5. Immunity
6. Blood reservoir
7. Synthesis of Vitamin D
Why is the skin considered an organ? correct answers It is composed of several different types of
tissue working together as a group
Name the four membrane types located in the skin correct answers 1. Serous Membrane
2. Mucous Membrane
3. Synovial Membrane
4. Cutaneous Membrane
What are the functions of the Serous Membrane? correct answers 1. Lines body cavities that are
not open to the outside of the body
2. Lubricates membrane surfaces with serous fluid to reduce friction and allows organs to slide
so that they don't stick and tear
What are the functions of the Mucous Membrane? correct answers 1. Lines body cavities that are
open to the outside of the body
2. Secretes mucus
What are the functions of the Synovial Membrane? correct answers 1. Forms the inner linings of
cavities
2. Secrete synovial fluid to lubricate the ends of bones
What are the functions of the Cutaneous Membrane? correct answers 1. Covers the surface of the
body
2. Epidermis anchored to the dermis
What are the three main layers of the skin? correct answers 1. Epidermis
2. Dermis
3. Hypodermis (subcutaneous)
What is the outermost layer of skin? correct answers The Epidermis
, What anchors the epidermis to the dermis? correct answers Basement Membrane
Does the Epidermis have a direct blood supply? correct answers No, fed by underlying dermis
Name the 5 Layers of the Epidermis (Superficial to Deep) correct answers 1. Stratum corneum
(superficial)
2. Stratum lucidum
3. Stratum granulosum
4. Stratum spinosum
5. Stratum basale (deep)
(Memory tip acronym: CLGSB for Carl Likes Getting Salted Butter)
Characterize the Stratum corneum correct answers 1. The most superficial layer of the epidermis
2. Consists of dead squamous-shaped keratinized cells
3. Waterproofed by keratinized cells
Characterize the Stratum lucidum correct answers 1. Translucent layer of the epidermis found
only in the thick skin of the fingers, palms, and soles
Characterize the Stratum granulosum correct answers 1. Epidermal layer where the keratinization
process begins and the cells begin to die
2. Contains visible granules
Characterize the Stratum spinosum correct answers 1. Spiny layer.
2. 8 to 10 layers of keratinocytes extensively linked by desmosomes.
3. Has dendritic cells, langerhans cells and melanin granules.
Characterize Stratum basale correct answers 1. The deepest layer of the epidermis consisting of
stem cells capable of undergoing cell division to form new cells (mitosis)
2. Layer that undergoes the most rapid mitosis
Name the four cell types that compose the epidermis correct answers 1. Keratinocytes
2. Melanocytes
3. Langerhans cells
4. Merkel cells
Characterize Keratinocytes correct answers 1. 90% of cells in the epidermis
2. Produce keratin which helps waterproof the skin
What is keratin? correct answers A tough, fibrous protein that waterproofs and protects the hair,
skin and nails; Created by keratinocytes
Characterize Melanocytes correct answers 1. 8% of cells in the epidermis
2. Produces melanin, which is responsible for skin, eye, and hair color and protects against UV
light
3. Humans are born with the same amount, they just produce different amounts of melanin
