| What are cartilaginous joints(amphiarthroses)? |
|
Definition
| Bones that articulate by either using hyaline cartilage or fibrocartilage. |
|
|
Term

|
Definition
Only very limited movment between bones in certain circumstances.
Example: During childbirth symphysis pubis facilitates the baby's passage through pelvis. |
|
|
Term
|
Definition
| Bones that have hyaline cartilage between articulating bones. |

|
|
Term
| What kind of joint is symphyses? |
|
Definition
| A pad or disk of fibrocartilage connects two bones. |
|
|
Term
| Give 2 examples of symphyses joints. |
|
Definition
| Symphysis pubis, articulation between the bodies of adjacent vertebrae. |
|
|
Term
| The points of contact between articular facets of adjacent vertebrae are considered _______ joints. |
|
Definition
|
|
Term
| Synovial(diarthroses) joints |
|
Definition
| Freely moveable, most numerous and most complex joints. Most bones in appendicular skeleton are these. |
|
|
Term
| List 7 structures of a synovial(diarthroses) joint. |
|
Definition
| Joint capsule, synovial membrane, articular cartilage, joint cavity, Menisci(articular disks), ligaments, bursae |
|
|
Term
| List 3 types of synovial(diarthroses) joints. |
|
Definition
| Uniaxial, Biaxial, Multiaxial |
|
|
Term
| Joint capsule(synovial joint) |
|
Definition
| Extension of the periosteum of each of the articulating bones. Capsule forms complete casing around the ends of bones, binding the to each other. |
|
|
Term
| Synovial membrane(synovial joint) |
|
Definition
| Moist, slippery membrane that lines the inner surface of the joint capsule. Attaches to articular cartilage. Secretes synovial fluid, which lubricates and nourishes the inner joint surface. |
|
|
Term
| Articular cartilage(synovial joint) |
|
Definition
| Thin layer of hyaline cartilage covering and cushioning the articular surfaces of bones. |
|
|
Term
| Joint cavity(synovial joint) |
|
Definition
| Small space between the surfaces of the two bones of the joint. Absence of tissue between articulating bones surfaces is what allows extensive movement. |
|
|
Term
| Menisci(articular disks) - (synovial joint) |
|
Definition
| Pads of fibrocartilage located between the articulating ends of bones in some diarthroses. The knee joint contains two menisci. |
|
|
Term
| Ligaments(synovial joint) |
|
Definition
| Strong cords of dense, white fibrous tissue at most synovial joints. These grow between the bones, lashing them together. |
|
|
Term
|
Definition
| Some joints contain this, pillow like structure formed of synovial membrane. Function to cushion the joint and facilitate movement of tendons. |
|
|
Term
|
Definition
| Inflammation of the bursa, because of excessive us of knee, elbow joints(where bursa are found). Treated with immobilization of joint and use of anti inflammatory drugs. |
|
|
Term
|
Definition
| Permit movement around only one axis and in only one plane. |
|
|
Term
|
Definition
| Diarthroses that permit movements around two perpendicular axes in two perpendicular planes. |
|
|
Term
|
Definition
| Permit movements around three or more axes and in three or more planes. |
|
|
Term
| Types, functions, examples of uniaxial joints. |
|
Definition
Hinge joints - permit only back and forth movements, flexion and extension., trochlea and semi ulnar notch.
Pivot joints - projection of one bone articulates with a ring or notch of another bone. For rotation, examples are : projection of second cervical vertebra that articulate with ring shaped portion of first cervical vertebra. Head of radius that articulates with radial notch of ulna. |
|
|
Term
| 2 types of biaxial joints and examples. |
|
Definition
| Saddle joints - only two in body, one in each body; Condyloid joints - condyles of the occipital bone fit into eleliptical depressions of the atlas; distal end of radius fits into depressions of the carpal bones. |
|
|
Term
| List 2 multiaxial joints, and examples |
|
Definition
Ball and socket joints(spheroid joints - most movable joints. Example shoulder and hip bones.
Gliding joints - joints between articular surfaces of successive vertebrae. Least movable joints. |
