| Question | Answer |
| Fiberous Joints | Held together by Dense Connective Tissue containing collagenous fibers. |
| Types of Fiberous Joints | 1) Syndesmosis 2) Suture 3) Gomphosis |
| Syndesmosis Joint | Bones bound togther by interosseous ligaments Flexible and may be twisted ex) distal ends of tibis and fibula (tibofibular articulation) |
| Suture | Only between flat bones of the skull no movement |
| Gomphosis Joint | Formed by the union of cone-shaped bony proces in a bony socket. ex) tooth fastended to jaw bone no movement |
| Cartilaginous Joints | Bones connected by Hyaline Cartilage or Fibrocartilage |
| Tyoes of Cartilagenous Joints | 1) Synchondrosis 2) Symphysis |
| Synchondrosis | Bones united by bands of Hyaline Cartilage. Temperary structures that dissapear during growth. No movement aftergrowth. Connects: epiphysis and diaphysis sternum and first rib |
| Symphysis | Articular surfaces seperated by thin layers of hyaline cartilage attached to band of fibrocartilage. Limited movement when back is bent or twisted. ex) joints btwn bodies of vertebrae. |
| Synovial Joints | Articulating bones surrounded by a joint capsule of ligaments and synovial membranes; ends of articulating bones covered by hyaline cartilage and seperated by synovial fluid. |
| Ball and Socket | Ball-shaped head of one bone articulates with cup-shaped socket of another. Movements in all planes. ex) shoulder, hip. |
| Condyloid | oval-shaped condyle of one bone articulates with elliptical cavity of another. Variety of movements, but no rotation. |
| Gliding | Articulating surfaces are neraly flat of slightly curved. Back and forth (sliding) and twisting. ex) wrist and ankle |
| Hinge | Convex surface of one bone articulates with concave surface of another. Flexion and extension. ex) elbow, joints of phalanges, back. |
| Pivot | Cylindrical surface of one bone articulates with ring of bone and fiberous tissue. Rotation. Joint btwn proximal ends of radius and ulna, neck. |
| Saddle | Articulating surfaces have both concave and convex regions; surface of one bone fits the complementary suface of another. variety of movements mainly in 2 planes. joint btwn carpal and metacarpal of thumb. |
