Tissues Flashcards
Groups of similar cells that carry out a common function
Tissues
Types of tissues…
Epithelial
Connective tissue
Muscle
Nervous tissue
Types of connective tissues
Cartilage, bone, blood, Proper (loose, dense regular and irregular)
What are the shapes of cells in epithelial tissue
Squamous, cuboidal, or columnar
What kind of layers are in epithelial cells
Simple, stratified, pseudostratified
Epithelial tissue classification…
Rest on basement membrane, cilitated, number of layers, and shape of cells
Functions of epithelial tissue
Protection, sensation, absorption, and secretion
Characteristics of epithelial tissue include…
Covers body surfaces In majority of glands Close together cells that form a lining Free and basal surface A vascular High regeneration capacity
What does a stratified surface mean
Stacked, many cells
Single layer of flattened cells, disc nucleus
Simple squamous
In alveoli and capillaries
Simple squamous
Function of simple squamous
Rapid diffusion
Large spherical nucleus, single layer of cubed cells
Simple cubodial
In kidneys and tubules
Simple cubodial
Function of simple cubodial cells
Secretion and absorption
Single layer of tall cells with round nuclei, may contain goblet cells
Simple columnar
In respiratory tract and digestive tract
Respiratory= ciliated simple columnar Digestive= nonciliated simple columnar
Function of simple columnar cilited and non ciliated
Ciliated= secrete mucus Non-ciliated= absorption and secretion
Thick membrane, several cell layers, surface cells flat
Stratified squamous
Surface cells dead and keratin filled basal cells active in mitosis
Stratified squamous keritinized
In skin
Keratinized stratified squamous
In esophaguses and oral cavity
Non kertitanized stratified squamous
Two layers of cube like cells
Stratified cubodial
Function of stratified cubodial and squamous
Protection
In ducts of salivary glands
Stratified cubodial
Many layers, basal cells are cubodial and superficial cells are columnar
Stratified columnar
