Long Bone - A type of bone that is longer than it is wide and has a shaft with two ends. Long bones are primarily found in the limbs (e.g., femur, humerus) and are crucial for movement, support, and red blood cell production in the marrow., Short Bone - A type of bone that is roughly cube-shaped, being nearly equal in length, width, and thickness. Short bones provide stability and some movement. Examples include the carpals (wrist bones) and tarsals (ankle bones)., Irregular Bone - Bones with complex shapes that do not fit into other categories. These bones often have specialized functions, such as protection of the spinal cord or attachment of muscles. Examples include vertebrae and certain facial bones., Flat Bone - Thin, flat, and often curved bones that provide protection for internal organs and surfaces for muscle attachment. Examples include the skull, ribs, sternum, and scapulae., Sesamoid Bone - A small, round bone embedded within a tendon or a muscle. Sesamoid bones protect tendons from stress and wear. The patella (kneecap) is the most prominent example., Axial - The part of the skeleton that forms the central supporting axis of the body. It includes the skull, vertebral column, and thoracic cage (ribs and sternum) and serves to protect the brain, spinal cord, and thoracic organs., Appendicular - The portion of the skeleton that includes the bones of the limbs and the girdles (shoulder and pelvic) that it is responsible for movement and interaction with the environment., Fixed Joint - A type of joint, also known as a fibrous joint, where bones are tightly connected by dense fibrous tissue and do not allow any movement. Examples include the sutures of the skull., Cartilaginous Joint - A joint where bones are connected by cartilage, allowing limited movement. These joints provide strength and flexibility. Examples include the vertebrae , Synovial Joint - A highly mobile joint characterized by a fluid-filled joint cavity. Allow a wide range of movements and are found in locations such as the knee, elbow, shoulder, and hip. Key features include a synovial membrane, cartilage, and ligaments.,
