Tissues Flashcards
What is a tissue?
A collection of cells containing a predominant cell type that work together to perform the same function
Name the 4 basic primary tissues
Epithelial tissue
Connective tissue
Nervous tissue
Muscle Tissue
State the function of epithelial tissue and an example of where it can be found
Protection and secretion
Skin
What are the defining histological characteristics of epithelial tissue?
Cells bound tightly together
Presence of basement membrane
Which layer supplies the epithelium and where is it found?
The lamina propria, located below the basement membrane
What are the two poles of an epithelial cell?
Apical - in contact with lumen
Basal - in contact with basement membrane
How is epithelium named?
Layer structure, cell shape and surface features
e.g stratified squamous
Name the different types epithelial layer types and an example of where they can be found
Simple - kidney
Stratified - skin
Pseudostratified - respiratory tract
Name two subdivisions of stratified epithelium and where they can be found
Keratinised - skin
Transitional - bladder
Identify the tissue type
Epithelial tissue

Skin
Identify the tissue type
Epithelial tissue
Simple columnar
Gut/ ovary
Identify the tissue type
Epithelial Tissue
Stratified columnar
Gland/ duct
Identify the tissue type
Epithelial tissue
Pseudostratified columnar
Trachea
Identify the tissue type
Epithelial tissue
Transitional
Urinary tract
What is the main function of simple epithelium and where can it be found?
Absorption, filtration and secretion
Kidney
What is the function of stratified epithelium?
Protection mostly but also secretion
Skin, glands and ducts
What is the function of pseudostratified epithelium and where can it be found?
Movement and secretion
Respiratory tract
State the function of connective tissue and an example of where it can be found
Connects and supports
Cartilage
What are the defining histological characteristics of connective tissue?
Few cells
Cells apart from each other
Extracellular matrix composed of fibres and ground substance
ECM + Cells = Connective tissue
ECM determines structural and functional properties
Name the 3 main types of connective tissue
Loose
Dense
Specialised
Name the 2 kinds of loose connective tissue
Areolar
Adipose
Name the 2 kinds of dense connective tissue
Regular
Irregular
Identify the tissue type
Epithelial tissue
Simple epithelia
Blood vessel
