Human Anatomy  Radiographic Anatomy Living Anatomy: 4 Methods: Inspection, Palpation, Percussion, Auscultation. Clinical or Applied anatomy Comparative Anatomy  Cells and Tissues Carry out all chemical activities needed to sustain life Cells are the building blocks of all living things Tissues are groups of cells that are similar in structure and function  Tissues A group of closely associated cells that have a similar structure and perform a related function Four primary types 1. Epithelium – Covering 2. Connective tissue – Support  Epithelial Tissues Found in different areas – Body coverings – Body linings – Glandular tissue Functions – Protection – Absorption – Filtration – Secretion  Connective Tissue Found everywhere in the body Includes the most abundant and widely distributed tissues Functions – Binds body tissues together – Supports the body – Provides protection  Connective Tissue Characteristics Variations in blood supply – Some tissue types are well vascularized – Some have poor blood supply or are avascular Extracellular matrix – Non-living material that surrounds living cells  Muscle Tissue Function is to produce movement Three types – Skeletal muscle – Cardiac muscle – Smooth muscle  Nervous Tissue Neurons and nerve support cells Function is to send impulses to other areas of the body – Irritability – Conductivity Figure 3.21  Regeneration of Tissues Tissues that regenerate easily – Epithelial tissue – Fibrous connective tissue and bone Tissues that regenerate poorly – Skeletal muscle Tissues that are replaced largely with scar tissue – Cardiac muscle – Nervous tissue within the brain and spinal cord
