Document Summary
The main type of fibrous connective tissue is . Areas subject to wear-and-tear that require protection are covered with epithelial cells in multiple layers. This is capable of great expansion but returns to its original form once tension is relaxed. Exocrine glands have ducts or tubes to carry secretions away from the gland. Endocrine glands secrete directly into the blood, which then carries their secretions to another area of the body. Hyaline, which reduces friction between joints, fibrocartilage, which is found between segments of the spine, knee, and hip, and elastic, which can spring back into shape after it is bent. Nervous tissue is supported by these specialized cells. Some of these cells protect the brain, others get rid of foreign organisms and cellular debris, and still others form the myelin sheath around axons. Serous line the wall s of the body cavities and are folded back on the surface of internal organs, forming their outermost layer.
