Chapter 9 Type Of Tissues Flashcards
Stratified squamous (keratinized) epithelial cells are found in the
epidermis
Which type of tissue has cube-shaped cells and can be found lining the kidney tubule
simple cuboidal epithelium
All glands in the body can be classified as either
exocrine or endocrine
The most abundant and widespread tissue in the body is
Connective
How group of cells similar in function and structure
Tissues
The tip of the nose and the external ear are composed of
elastic cartilage
There are four main types of connective tissue. They are:
Fibrous (e.g., loose fibrous [areola], adipose, reticular, and dense)
Bone (e.g., compact and cancellous [spongy] bone)
Cartilage (e.g., hyaline, fibrocartilage, and elastic)
Blood
Muscle Tissue
Muscle tissue is responsible for movement. This tissue is composed of cells that have the ability to shorten or contract. When this occurs, they cause movement of a body part. There are three types of muscle:
skeletal
smooth
cardiac
skeletal muscle
Striated or voluntary muscle tissue; known as skeletal muscle because it attaches to bones.
smooth muscle
Visceral or involuntary muscle tissue found in blood vessels and other tube-shaped organs.
cardiac muscle
Involuntary muscle tissue that composes the bulk of the heart.
Cutaneous Membrane
The cutaneous membrane is a subdivision of the epithelial membrane. It is also known as the skin and is the primary organ of the integumentary system.
The cutaneous membrane covers the surface of the body and consists of stratified squamous epithelium and the underlying connective tissues. The outer layer of skin (epidermis) protects the body from invading microorganisms, and the underlying connective tissue layer (dermis) contains the majority of the skin appendages. The cutaneous membrane is thick, relatively waterproof, and dry.
Serous membranes are composed of two distinct layers of tissue:
The parietal layer lines the walls of body cavities, much like wallpaper.
The visceral layer covers the surfaces of organs found in body cavities.
Serous Membrane
Serous membranes are epithelial membranes that are located on surfaces of closed body cavities. They secrete a thin, watery fluid that helps reduce friction and serves as a lubricant when the organs rub against each other or the cavities that contain them.
Mucous Membrane
Mucous membranes are epithelial membranes that line body surfaces leading to the outside. Most mucous membranes secrete mucus that keeps the membrane moist and lubricated. Examples include those membranes lining the respiratory, digestive, urinary, and reproductive systems.
Connective Tissue Membrane
Synovial membranes belong to the category of connective tissue membranes because they contain only connective tissue and line joint cavities. Because synovial membranes do not contain any epithelium, they cannot be classified as an epithelium membranes, yet there are similarities:
Like serous membranes, synovial membranes line cavities that do not lead to the outside.
Like epithelial membranes, synovial membranes secrete a fluid to prevent friction.
The membrane that lines the urinary tract is __
Mucous
The serous membrane of the abdominal cavity is the __.
Peritoneum
Synovial membrane lines the small, cushion-like sacs called bursae.
True or False
True
Connective tissue membrane has one layer of epithelium.
True or false
Connective tissue membrane has no epithelium.
True
The serous membrane of the thoracic cavity is the __.
Pleura
The skin, or cutaneous membrane, has two distinct layers:
The outermost thin layer of the skin is the epidermis.
The deeper thick layer of the skin is the dermis.
: contribute colored pigments to the skin
Melanocytes
What are the four shapes epithelial cells
Spumous
Cuboidal
Columnar
Pseudostratified
Which type of tissue has cube-shaped cells and can be found lining the kidney tubules?
simple cuboidal epithelium
There are four main types of connective tissue. They are:
Fibrous (e.g., loose fibrous [areola], adipose, reticular, and dense)
Bone (e.g., compact and cancellous [spongy] bone)
Cartilage (e.g., hyaline, fibrocartilage, and elastic)
Blood
What are the five most important functions of epithelial Tissue
The answer may include any three of the following: protection, sensory functions, secretion, absorption, and excretion.
What is thin skin
Has hair and smooth surface
What is thick skin?
Has no hair and ridged surface
Contributes to skin colour and filters UV light
Melanocytes
