Tissue Flashcards
Three embryonic tissues called germ layer
Endoderm, mesoderm, ectoderm
Four main types of tissues
Epithelial, muscle, connective, nervous tissues
Two classification of epithelial tissues
Covering and lining, gladular epithelium
Epithilia that consist one layer with the function of absorption, secretion, and filtration
Simple epithelia
Three types of simple epithelia
Simple squamous epithelium, simple cubiodal epithelium, simple columnar epithelium
Have scale like appearance. Ex: endothelium and mesothelium.
Simple squamous epithelium
Have box like cells. Can be found in kidney tubules
Simple cubiodal epithelium
Column like cell which nucleus are elongated and located at the basal end of the cells. These are form in the linig of some sections of the DIGESTIVE SYSTEM and parts of the FEMALE REPRODUCTIVE TRACT
Simple columnar epithelium
Type of epithelium that appears to be stratified
Pseudostratified columnar epithelium
Epithelial cell that consist of several stackes layers
Stratified epithelium
Thus type of epithelium is found in respiratory tract where some of the cells have cillia
Seen in trachea, the cillia moves the mucus produced by the goblet cell
Pseudostratified columnar epithelium q
This functions as protection against physical and chemical wear and tear
Stratified epithelium
The apical cells and basal layer contains either columnar or cubiodal. Most common type of stratified epithelium in the hunan body. The top layer may be covered with DEAD CELLS with KERATIN
Stratified squamous epithelium
Functions as protective tissue. Can be found in sweat glands, salivary gland, mammary gland.
Stratified cubiodal epithelium
Functions for secretions and protection. Can be found in male urethra and some duct glands
Simple columnar epithelium
Can only be found in the urinary system specifically in the bladder, urethra, and the ureters. Kind of stratified epithelium that has gradual CHANGES IN SHAPE of the APICAL CELLS.
Ex: bladder fills with urine
Transitional epithelium
Epithelial tissue that makes up the glands such as THYROID, SWEAT, DIGESTIVE and ADRENAL GLANDS that are responsible for SECRETION of chemical substances
Glandular epithelium
Ductless(no passage) gland that release secretion(hormones) into the surrounding tissues and fluids.
Endocrine glands
Secretion (breast milk, saliva, and sweat) leaves through a duct(passage) that leads to epithelial surface
Exocrine glands
Binds, supports, protect, connect. Can be found in mesoderm. It is dispersed in a matrix.
Connective tissue
Fibroblast
Connective tissue proper
Shock absorption and binding tissue
Loose connective tissue
Fat. Fat storage. Insulation.
Adipose
Weblike. Underlies most epithelia
Areolar tissue
