| 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.
🗑
