  2. What is tissue? • A tissue is a group of similar cells that perform a common function. • All tissues are surrounded by or embedded in a nonliving intercellular material called a matrix. • Tissues differ regarding the amount and kind of intercellular matrix. • Histology is the biology of tissues.

  3. Epithelial Tissue • Classification: • Membranous epithelium • Glandular epithelium • Functions: • covers and protects the body surface • lines body cavities • specializes in moving substances into and out of blood • Forms many glands Click on image to find out more about epithelial tissue.

  4. Connective Tissue • The most widespread tissue of the body • Classification: • Fibrous • Loose, Adipose, Reticular, and Dense • Bone • Cartilage • Hyaline, fibrocartilage, and elastic • Blood Click the picture to learn more about connective tissue.

  5. Connective Tissue • Functions • Connects tissues to each other • Connects muscles to muscles, muscles to bone, and bones to bones • Forms a supporting framework for the body as a whole and for its organs individually • Transports a large array of substance between parts of the body

  6. Muscle Tissue • Classification • Skeletal muscle tissue • Muscles attached to bone • Smooth muscle tissue • Found in walls of the stomach, intestines, and blood vessels • Cardiac muscle tissue • Makes up the walls of the heart

  7. Nervous Tissue • Function: • To rapidly regulate and integrate the activities of the different parts of the body • Found in the brain, spinal cord, and the nerves. • Two kinds of cells • Nerve cells/neurons • Conducting units of the system • Neuroglia • Special connecting and supporting cells Click on picture to learn more about nervous tissue.
