M100 integumentary review Flashcards
What structures does the integumentary system include
Skin and appendages
State the appendages of the skin
Nails, hair, glands
What does integument mean
“To cover/ Covering”
What is the principle organ of the integumentary system
Skin
What are the sheet like structures of the I.S called
Membranes
What cover and protect the body surface, line hollow cavities and cover the inner surfaces of hollow organs
Membranes
What anchors organs to eachother
Membranes
What anchor organs to bones
Membranes
What covers internal organs
Membranes
What secrete lubricating fluids that reduce the friction of organ movement
Membranes
What secretes lubricating fluids to decrease friction between bone and joint
Membranes
State the two major types of membranes
Epithelial and connective
State the three types of epithelial tissue
Cutaneous, Mucous, and serous
Whats the primary organ of the integumentary system
Cutaneous membrane
What type of membrane is also called skin
Cutaneous membrane
State the largest organ of the body
Cutaneous Membrane
Which membrane has a superficial layer of epithelial cells and underlying area of supportive connective tissue
Cutaneous membrane
Which epithelial membrane is composed of two layers of tissue known as parietal and visceral
Serous membrane
The ______ sheet of serous membrane is a thin layer of simple squamous epithelium
Epithelial
The _____ tissue layer of serous membrane forms a very thin glue like basement membrane that holds and supports epithelial cells
Connective
The serous membrane that lines the walls of body cavities
Parietal
The serous membrane that covers the surface of organs
Visceral
The thoracic cavity serous membranes
Pleura
The abdominal cavity serous membranes
Peritonium
____ membranes secrete a thin watery fluid that helps reduce friction and serves as a lubricant while organs rub together and on cavity walls
Serous
Epithelial membranes that line body surfaces opening directly to the exterior of the body
Mucous membrane
These membranes line the digestive, respiratory, urinary and reproductive tracts
Mucous membranes
The thick, slimy material secreted by epithelial cells of most mucous membranes
Mucus
This keeps mucous membranes moist and soft
Mucus
A point of fusion where the skin and mucous membranes meet
Mucocutaneous Junctions
Places of the body without I.S accessory organs including eyelids ,vulva , nasal openings ect
Mucocutaneous junctions
______ membranes contain no epithelial tissue
Connective tissue
Connective tissue membranes that line the spaces between bones and joints
Synovial membranes
These membranes are smooth and slick; they secrete a thick colorless lubricating fluid called synovial fluid
Synovial membranes
These membranes line the Bursae found between moving body parts
Synovial membranes
AKA oil glands
Apocrine
Sebaceous
The outer later of the skin
Epidermis
The layer of the skin with stratified squamous epithelium
Epidermis
The deeper layer of skin
Dermis
This layer of skin is mostly made up of connective tissue
Dermis
This supports the layers of skin and is a thick layer of loose connective fat and tissue
Subcutaneous
AKA Hypodermis
Subcutaneous
This insulates the body from extreme heat and cold
Fatty fat
This structure of skin serves as a stored source of energy can can be used as a food source
Adipose
This structure of skin acts as a shock absorbing pad and helps protect underlying tissues from injury
Adipose
The structure of skin that contains tightly packed epithelial cells arranged in many different layers
Epidermis
The innermost layer of the epidermis
Stratum Basal
The cells at the innermost layer of the epidermis reproduce themselves via _____
Mitosis
As cells from the stratum germinativum move towards the surface of the skin the cells cytoplasm is replaced with ______
Keratin
A protein substance thats tough and waterproof
Keratin
This substance provides cells on the outer layer of the skin with a horny abrasion resistance, protective quality
Keratin
The tough outer layer of the epidermis
Stratum corneum
