| Question | Answer |
|---|---|
| Fibrous | Articulating bones fastened together by thin layer of dense connective tissue |
| Fibrous-Syndesmosis | Bones bound by interosseous ligament. Flexible and may be twisted. |
| Fibrous-Suture | Flat bones united by sutural ligament. No movement. |
| Fibrous- Gomphosis | Cone-shaped processs fastened in bony socket by peridontal ligament. No movement |
| Cartilaginous | Articulating connected by hyaline cartilage or fibrocartilage |
| Cartilaginuous-Synchondrosis | Bones united by bands of hyaline cartilage. Movement occurs during growth process until ossification occurs. |
| Cartilaginuous-Symphysis | Articular surfaces separated by thin layers of hyaline cartilage attached to band of fibrocartilage. Limited movement, when bent or twisted. |
| Synovial | Articulating bones surroumded by a joint capsule of ligaments and synovial membranes; ends of articulating bones covered by hyaline caetilage and separated by synovial fluid. |
| Synovial- Ball-and-socket | Bal-shaped head of one bone articulates with cup-shaped socket of another. Movements in all planes;rotation. |
| Synovial-Condyloid | Oval-shaped head condyle of one bone articulates with elliptical cavity of another. Variety of movements in different planes. No rotation or twisting. |
| Synovial-Gliding | Articulating surfaces are nearly flat or slightly curved. Sliding or twisting movement. |
| Synovial-Hindge | Convex surface of one bone articulates with concave surface of another. Flexion and extension movement. |
| Synovial-Pivot | Cylindrical surface of one bone articulates with ring of bone and fibrous tissue. Rotation. |
| Synovial-Saddle | Articulating surfaces have both concave and conves regions; sruface of one bone fits complementary surface of another. Variety of movements, mainly in two planes. |
| Flexion | Bending parts at a joint |
| Extension | Straightening parts at a joint |
| Hyperextension | Excess extension of parts at a joint, beyond atomical position |
| Dorsiflexion | bending the foot at the ankle toward the shin |
| Plantar Flexion | Bending the foot at the ankle toward the sole |
| Abuction | Moving a part away from the midline |
| Adduction | Moving a part toward the midline |
| Rotation | Moving a part round an axis |
| Circumduction | Moving a part so that its end follows a circular path. |
| Supination | Turning the hand so the palm is upward or facing anterirorly |
| Pronation | Turning the hand so the palm is downward or facing posteriorly |
| Eversion | Turning the foot so the sole faces laterally |
| Inversion | Turning the foot so the sole faces medially |
| Protraction | Moving a part toward |
| Retraction | Moving a part backward |
