Classification of Tissues

Study Notes

Connective Tissue
- Anchors and supports body organs
- Most durable tissue type
- Characterized by abundant nonliving extracellular matrix
- Most widespread tissue in the body
Epithelium
- Lines body cavities, covers external surfaces
- Functional roles include absorption, secretion, and filtration
- Capable of synthesizing hormones
Muscle Tissue
- Responsible for pumping blood and flushing urine
- Enables voluntary movements, e.g. swinging a bat
- Major function is contraction
Nervous Tissue
- Transmits electrochemical impulses
- Primarily involved in regulating and controlling body functions
- Forms the brain and nerves

Types of Epithelium

Simple Columnar Epithelium
- Non-ciliated type lines digestive tract, gallbladder, and excretory ducts
- Ciliated variety found in small bronchi and uterine tubes
Simple Cuboidal Epithelium
- Located in kidney tubules, small glands, and ovary surface
Simple Squamous Epithelium
- Found in kidney glomeruli and air sacs of lungs
- Also lines the heart, blood vessels, lymphatic vessels, and ventral body cavity
Pseudostratified Columnar Epithelium
- Non-ciliated type present in male reproductive ducts
- Ciliated variety lines the trachea and upper respiratory tract
Stratified Squamous Epithelium
- Non-keratinized version lines moist surfaces like the esophagus and vagina
- Keratinized variety forms the epidermis of skin
Stratified Cuboidal Epithelium
- Seen in largest ducts of sweat glands and mammary glands
Stratified Columnar Epithelium
- Rare, present in small quantities in male urethra and large glands
Transitional Epithelium
- Lines the ureters, bladder, and part of urethra

Types of Connective Tissue

Adipose Connective Tissue
- Functions as a fat storage depot
- Provides insulation against heat loss
Areolar Connective Tissue
- Composes basement membranes
- Acts as soft packaging tissue with a jellylike matrix
Dense Fibrous Connective Tissue
- Attaches muscles to bones and bones to bones
- Found in the dermis of the skin
Elastic Cartilage
- Provides flexible structure for the external ear
Fibrocartilage
- Forms intervertebral discs
Hematopoietic Tissue
- Responsible for replenishing red blood cells
Hyaline Cartilage
- Forms structures like larynx and costal cartilages
- Characterized by a glassy, smooth matrix
Osseous Tissue
- Makes up the hip bone
- Matrix is hard due to calcium salts, providing levers for muscular action
