Answers
1)Fibrous joints contain fibrous connective tissue and cannot move; fibrous joints include sutures, syndesmoses, and gomphoses. Cartilaginous joints contain cartilage and allow very little movement; there are two types of cartilaginous joints: synchondroses and symphyses.
2)Spongy bone Compact bone tissue is composed of osteons and forms the external layer of all bones. Spongy bone tissue is composed of trabeculae and forms the inner part of all bones.
3)elbow The elbow is a complex joint formed by the articulation of three bones –the humerus, radius and ulna. The elbow joint helps in bending or straightening of the arm to 180 degrees and assists in lifting or moving objects.
4) Pivot joints Pivot joints allow a rotating or twisting motion, like that of the head moving from side to side. Ball-and-socket joints allow the greatest freedom of movement.
5) Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made. Bones work with muscles and joints to hold our body together and support freedom of movement. This is called the musculoskeletal system.
6)
C1, the atlas, has no spinous process and articulates with the occipital condyles of the occiput bone of the skull, forming the occipital-atlanto (OA) joint. It connects the skull to the neck, also providing attachment points for some neck muscles. It also functions to bear the weight of the skull, providing support
7) Hinge joints are those that allow movement along one plane. They facilitate bending and straightening actions, such as flexing a finger
8)The tough, thin outer membrane covering the bones is called the periosteum. Under the hard outer shell of the periosteum are tunnels and canals. ... Muscles, ligaments, and tendons may attach to the periosteum.
9) Our bone marrow produces blood cells, called red blood cells, platelets, and white blood cells.
10)A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
