Two types of bone can be identified by the naked eye: compact bone solid or dense appearance. In a typical adult, about half of the bone marrow is red and half is yellow, with the red bone marrow concentrated in the spongy bone of the pelvis, ribs, skull, and vertebrae. There are also many blood vessels present in spongy bone that provide nutrients to the bone marrow and bone tissue. There are many types of connective tissue. What is the function of synovial membranes? Loose connective tissues have three types of fibers to fill in small spaces: collagenous, elastic and reticular. - Definition, Types & Function, Psychological Research & Experimental Design, All Teacher Certification Test Prep Courses, What Is Epithelial Tissue? These layers of bone tissue look similar to the rings inside a tree trunk. Synovial membranes are connective tissue membranes that protect and line the joints. These cells contain large quantities of Histamine the chemical responsible for many allergies. A adipose tissue is a loose connective tissue that is part of the body. Human body tissue makes up organs and other body parts. This Tissue is of 3 types as: Skeletal muscle tissue; Cardiac Tissue; Smooth muscle tissue; 1.2-Epithelial Tissue. Epithelial tissues act as coverings controlling the movement of materials across the surface. Osteocytes are constantly monitoring the bone tissue that surrounds them, and they have the ability to both produce new bone and destroy damaged bone if they are activated by stress or damage to the tissue around them. Blood transports digested food. Within each Haversian canal, there are blood vessels that supply nutrients to the cells living within the bone. 3 What are the 3 tissue types in the brain?
