I. Define tissue and describe the importance of tissue level organization to an organism. II. Describe the structure and function of epithelial, connective, muscle, and nervous tissue.
1. What is a tissue? - a group of cells that usually have a common origin in an embryo and function together to carry out specialized activities. 2. What are the four basic types of human tissues? All cells and tissues in the body derive from three germ layers in the embryo: the ectoderm, mesoderm, and endoderm. Different types of tissues form ...
Tissues are a collection of cells and their products which have a common fundamental function and in which one particular type of cell predominates: • Epithelial tissue – forms a protective layer both inside and on the surface of the body. Examples of this tissue are the skin, glands and linings of the various body systems.
Connective Tissue: bind, support, protect, serve as frameworks, fill spaces, store fat, produce blood cells, protect against infection, and repair tissue damage. . Unlike epithelial tissues, connective tissues have abundant matrix, or intercellular material, throughout, and have good blood supplies (except cartilage).
Histology is the study of cells, tissues and organs as seen through the micro-scope. Although this atlas is a guide to biological structure that can be observed through the light microscope, histology also includes cellular detail down to the molecular level that can be observed using an electron microscope.
This module is a complete overview of the microscopic structure of all the basic tissues of the body. The course examines how cells are assembled into tissues and how these tissues accomplish coordinated functions.
