Body Tissues & Membranes Ch.4 Anatomy and Physiology Miss Tavitian

What is a tissue? group of cells with common structure and function

4 Major Types of Tissue  Epithelial Tissue  Connective Tissue  Muscular Tissue  Nervous Tissue

4 Major Types of Tissues 1. Epithelial tissue (aka Epithelium) 0 Covers the body surfaces 0 lines the body

Epithelial Tissue 0 Tightly packed cells 0 Has basement membrane and apical surface 0 avascular (lack of blood vessels) 0 has a nerve supply 0 high capacity for cell renewal by cell division

Characterized by #layers & Shape

Simple Squamous Epithelium

Stratified Squamous Epithelium

Simple Cuboidal Epithelium

4 Major Types of Tissues 2. Connective Tissue 0 connects and supports body parts

4 Major Types of Tissues 0 Muscular – Contracts

4 Major Types of Tissues 0 Nervous - Communicates
