|
|
|
How is the Epithelial Tissue classified?
|
(1) By the number of layers (2) By the arrangement shapes
|
|
|
What is simple epithelium main functions?
|
absorption, secretion, filtration
|
|
|
What are some types of simple epithelium tissues?
|
(1) Simple squamous (2) Simple cuboidal (3) simple columnar (4) Pseduostratisfied.
|
|
|
What is the stratified tissues main functions?
|
Protection
|
|
|
Where is simple columnar found in the body?
|
In the digestive tract.
|
|
|
Where is cuboidal tissue found?
|
Form the smallest ducts of glands and many kidney tubules.
|
|
|
Where is the stratified cuboidal epithelium found?
|
Mostly in the ducts of the larger glands.
|
|
|
Where is the stratisfied columnar found?
|
Limited distributed in the pharynx, male urethra
|
|
|
Where does transitional epithelium found??
|
It lines hollow organs.
|
|
|
What are the two types of glandular epithelial?What are their functions?
|
(1) Endocrine- ductless gland that releases hormones within the bloodstream. (2) Exocrine- Secrete onto surface of body cavities.
|
|
|
The exocrine gland secretes what two products?
|
(1) Merocrine-produced and released through exocytosis. (2) Holocrine-cell ruptures
|
|
|
Where does connective tissue arise from?
|
It arises from mesenchyme which is embryonic tissue.
|
|
|
What are the four main classes of connective tissues?
|
(1) Bone (2) Blood (3) Cartilage (4) Connective Tissue Proper
|
|
|
What are the major functions of the connective tissue?
|
(1) binding, support (2) protection (3) insulation (4) transportation
|
|
|
What are some structural elements of connective tissue?
|
(1) ground substance[space filling] (2)Fibers [collagen,elastic,reticular] (3) Cells
|
|
|
What are some common characteristics of connective tissue?
|
(1) Common origin (2) degrees of vascularity (3) Nonliving extracellular matrix
|
|
|
What are the respected cells structures of connective tissue?
|
(1) Fibroblast[Connective Proper] (2) Chondroblast[Cartilage] (3) Osteoblast[bone] (4) hematopoietic[blood]
|
|
|
Why is blood classified as a connective tissue?
|
It's developed by mesenchyme and is surrounded by blood plasma
|
|
|
What are the two subclasses of connective tissue proper?
|
Loose and Dense
|
|
|
What is areolar connective tissue?
|
It is a loose connective tissue that binds body parts together while allowing them to move freely over each other.
|
|
|
What is adipose connective tissue?
|
It's a loose, richly vascularized tissue that is storage.
|
|
|
What is reticular connective tissue?
|
It's a loose tissue that forms the internal network.
|
|
|
What are the two subclasses of the dense tissue? What are the respective functions?
|
(1) Dense Regular-dense packed collagen fibers running in the same direction (2) Dense Irregular- thick bundle of collage that run in the irregular pattern. Found in the dermis.
|
|
|
What are the three different type of cartilage connective tissue?
|
(1) Hyaline (2) Elastic (3) Fibrocartilage
|
|
|
What are the three types of muscle tissue?
|
(1) Skeletal (2) Cardiac (3) Smooth
|
|
|
What is the cutaneous membrane (skin) made of?
|
It consist of a kerantinized squamous epithelium firmly attached to a thick layer of dense irregular connective tissue.
|
|
|
What is the mucous membrane made of?
|
It's made of either stratified squamous or simple columnar epithelia.
|
|
|
What does the serous membrane consist of?
|
It consist of simple squamous epithelium resting on a loose (areolar) tissue.
|
|
|
What are the three membranes?
|
(1) cutaneous (2) mucous (3) serous
|
