List three fibrous joints and give an example |
Suture (sagittal suture of the skull), syndesmosis (tibia & fibula w/ interosseous membrane), gomphosis (tooth in a socket) |
|
|
Describe all three fibrous joints |
Suture: union of two bones by ligament or membrane, immovable. Syndesmosis: bone connected to bone by a dense fibrous membrane or cord, very little motion. Gomphosis: Bony surfaces connected as a peg in a hole. |
|
|
List and describe the two types of cartilaginous joints |
Synchondrosis: Attached by hyaline cartilage, i.e. the sternum and true ribs. Symphysis: two bones with hyaline cartilage, slight motion, i.e. pubic symphysis. |
|
|
Give an example of the three types of synovial joints |
Uniaxial: hinge elbow joint Biaxial: condyloid joints of MCP Multi-axial: ball and socket like hip and GH |
|
|
List the 5 distinguishing characteristics of a synovial joint |
joint cavity, articular cartilage, synovial fluid, fibrous joint capsule, synovial membrane. |
|
|
Where in joints are free nerve endings found? What do they tell us? Body distribution? |
Joint capsule, ligaments, synovium, fat pads. They tell us about non-noxious mechanical stress, and also noxious mechanical or biomechanical stimuli. All joints. |
|
|
Where in joints are golgi ligament endings found? What do they tell us? Where in the body? |
ligaments, bony attachment of ligaments. Tension or stretch on ligaments. Majority of joints. |
|
|
Where in joints are golgi-mazzoni corpuscles found? Tell us? Which joints? |
Joint capsule. Compression of joint capsule. Knee joint and joint capsule. |
|
|
Where in joints are pacinian corpuscles found? What do they tell us? Which joints? |
Fibrous layer of the joint capsule. Vibration, acceleration and high velocity changes in joint position. All joints. |
|
|
Where in joints are ruffini endings found? What do they tell us? Which joints? |
fibrous layer of joint capsule. stretching of joint capsule, amplitude and velocity of joint position. More in proximal joints. |
