Tissues Flashcards
What covers most glands
Glandular epithelium
What is attached to underlying connective tissues
Basal surface
What is the high regenration of epithelium property due to
High ability of mitosis
Function of epithelial tissue
Forms boundaries between different environments and provides protection
Function of connective tissue
Supports,protects, binds tissues to none another
Before a specimen is viewed
it is preserved,cut, and stored
What type of epithelium forms outer skin covering and lines open cavities
Covering and lining epithelium
Apical surface
Boarders open space
Basal surface
Lies next to underlying connective tissue
Most apical surfaces have______which increases surface area. their fluffy appearance is called____
Microvilli, brush boarder
Basal lamina is present adjacent to____, it is a thin supporting sheet consisting of_____ secreted by______. It acts as a _____ filter
Basal surface of epithelium, glycoproteins,epithelial cells, selective
How are sides of adjacent sheets held
Tight junctions or Desmoses
Basement membrane is in between epithelial and _____ tissue
Connective
Types of basement membrane
Basal and reticular lamina
Avascular
Does not contain blood vessels
Innervated
Supplied by nerve fibers.
How are epithelial cells nourished
By substances diffusing from blood vessels in the underlying connective tissue
Simple epithelial
Consists of a single layer and found where absorption secretion and filteration
Sterilfied tissues
Two or more cell layer, common in high abrasion areas
Squamous tissues
Are flattened
Cubodial tissues
Are boxlike
Columnar
Column shape
Location of simple squamous
Kidney glamourli, air sacs of lungs, lining of heart, blood vessels, lymphatic vessels
Location of simple cubodial
Kidney tubules, ducts, secretory portion of small glands, ovary surface
Location of simple columnar
Digestive tract, gall bladder
Pseudostratified
Single layer of cells differing heights,may contain mucus ,secreting cells and bear villi
Mesotheliom
The epithelium found in serous membranes
Starified squamous
Forms the moist lining of esophagus, mouth ,and vagina
Transitional epithelial location
Lines uterus, bladder, and part of the urthera
Function of scanning electron microscopy
Provides 3d images of tissue
Individual hormone______cells are scattered in digestive tract
Secreting
Ducts of simple glands
Unbranched ducts
Merocrine glands
Secrete their products by exocytiosis
Secretory cells of holocrine glands
Accumulate their products within them until they rupture , ruptured cells are replaced by division of underlying cells
Holocrine gland example
Sebaceous gland
The most abundant tissue
Connective tissue
Poorly vascularized tissue
Connective tissue
Avascular tissue
Cartilage
Tissues with rich blood supply
Bone,blood
Mesenchyme
Embryonic tissue where all connective tissues arise
