INTRODUCTION TO THE BODY • TISSUES, a group of similar cells and their intercellular material which perform a common, specialized function. • ORGANS, of tissues organized together for a common, specialized function. INTRODUCTION TO THE BODY • ORGAN SYSTEMS, organs assiocated for a common function. • ORGANISM, a complete assemblage of interactive organ systems. TISSUES • Epithelial • Connective • Nervous • Muscular EPITHELIAL • Covering or linings of surfaces. • Three shapes of cells: squamos, cuboidal, columnar • Three arrangements: simple, stratified, psuedostatified EPITHELIAL EXAMPLES CONNECTIVE TISSUES • Most abundant tissues and very diverse. • Consists of a cellular component and the extra-cellular matrix. • GENERAL TYPES: Connective tissue proper, Cartilage, Bone, Vascular (blood components). CONNECTIVE TISSUES MUSCULAR TISSUE • Affects movement: locomotion, movement of food, movement of circulatory fluid. • Is contractable, excitable, extensible, and elastic. • Three types with different characteristics and functions. MUSCLE TYPES NERVOUS TISSUE • Excitable • Conducts impulses • Rapid communication and information processing. NEURONS TISSUES • Epithelial • Connective • Nervous • Muscular BODY ORIENTATION TERMINOLOGY used on bilaterally symmetrical animals: Dorsal/ventral Anterior/posterior Right/left Proximal/distal Superior/inferior (humans) How do organ systems develop? • Are derived from initial tissue layers of the organism. • Endoderm • Ectoderm • Mesoderm • Endoderm produces the gut and it’s related organs. • Ectoderm produces the epidermis and the nervous system. • Mesoderm produces the dermis, muscles, skeleton, circulatory system, kidneys, and the reproductive system. Learning the systems of the animal body. • What does the system do for the organism? • What are the structures? • What do the structures do? • How and with what other systems does this integrate its activity to keep the organism alive?
