Four Fundamental Types Of Tissues Flashcards
What are the four fundamental types of tissues
Epithelial
Connective
Muscular
Nervous
Epithelial tissue is composed of
Epithelial cells
Extra or intercellular substance
Consists of contiguous cells in opposition over a large portion of their surface
Cells are arranged in sheets or layers
Epithelial tissues
Epithelial tissues cells rest on a continuous extracellular layer called
Basal lamina
Epithelial tissues with absence of blood vessels among the cells is called
Avascularity
It forms a boundary layer that controls the movement of substances between the external and internal environment
Epithelial tissue
Maybe specialize for absorption and secretion and may bear motile cilia to move a film of fluid or mucus over its surface
Epithelial tissue
It is on the exterior of the body and resist abrasion and dehydration
Epithelial tissue
The three primary germ layers or origins of epithelium
Ectoderm mesoderm and endoderm
It is composed of the epidermis and glandular appendages of the skin
Ectoderm
This composed of the vascular endothelium kidneys and reproductive ducts
Mesoderm
Aries composed of the intestinal tract liver pancreas and lungs
Endoderm
Types of epithelial tissue
Membranous epithelium
Glandular epithelium
Epithelial cells covering services and lining cavities
Membranous epithelium
It describes the number of layers of cells
Subtypes of epithelial tissue
Four sub types of epithelial tissue
Simple epithelium
Stratified epithelium
Pseudo stratified epithelium
Transitional epithelium
1 layer of epithelial cell on a basement membrane or basal lamina
Simple epithelium
Describe two or more layers of epithelial cell on top of a basement membrane
Stratified epithelium
Describe one layer of epithelial cell on basement membrane but cells have different sizes nuclears are located in different areas inside the cell
Pseudostratified epithelium
The thickness of the layer of epithelial cells varies when the organ functions address the layer is thick where in functions it becomes thin
Transitional epithelium
It is according to the shape of the cell of the uppermost number of layers
Specific subtypes of membranous epithelium
Types of simple epithelium
Simple squamous epithelium
Simple cuboidal epithelium
Simple columnar nonciliated epithelium
Simple columnar ciliated epithelium
An example of this is endothelium mesothelium parietal layer of bowman’s capsule and pulmonary alveoli
Simple squamous epithelium
Sales lining the thyroid follicles germinal epithelium of ovary and ducts of many glands
Simple cuboidal epithelium
It is Lining the GIT and gallbladder
Simple columnar nonciliated epithelium
It lines the uterus and fallopian tubes
Simple columnar ciliated epithelium
Three types of stratified epithelium
Stratified squamous non keratinized epithelium
Stratified squamous keratinized epithelium
Stratified cuboidal epithelium
Stratified columnar epithelium
It lines the oral cavity esophagus and vagina
Stratified squamous non keratinized non-cornified epithelium
It is in the epidermis
Stratified squamous keratinized cornified epithelium
It lines the cells of the ducts of sweat and sebaceous glands
Stratified cuboidal epithelium
It lines the cells of the ducts of salivary and mammary glands
Stratified columnar epithelium
Two types of pseudo stratified columnar epithelium
Nonciliated and ciliated
It lines the docks of male reproductive and accessory male reproductive organs
Pseudo stratified columnar nonciliated epithelium
