Lesson 4.4 Flashcards
A joint is a point of contact between
2 bones
Bone and cartilage
Teeth and bones
Definition of arthrology
Study of joints
Definition kinesiology
Study of motion
What are the different types of structural joints
Fibrous joints
Cartilaginous joints
What are the different types of functional joints
Synarthrosis
Amphiarthrosis
Diarthrosis
Which types of joints had a synovial cavity?
Synovial
Which types of joints don’t have a synovial cavity
Fibrous
Cartilaginous
Which joints is immovable?
Synarthrosis
Which joints is slightly movable
Amphiarthrosis
Which joints is freely movable
Diarthrosis
Which are the most common functional joints?
Diarthrosis
What are the type of tissue in the fibrous joints
Dense irregular connective tissue
In the fibrous joints which type of movement do we have?
Synarthrosis or Amphiarthrosis
Which are the 3 structurales types do we have in fibrous joints
Suture
Interosseous membranes
Syndesmoses
->gomphoses
What types of tissue there is in suture and when we use suture?
Thin layer of dense irregular connective tissue ( rich in collagen fibres)
In bone of the skull
What is synostosis
When replaced by bone in adults, complete fusion of bones
Where do we find syndesmosis
Between long bones of the body
Ex: distal tibiofibular joint
When do we find interosseous membrane?
What type of movement is it
Between radius and ulna
Between tibia and fibula
Slightly movable ( Amphiarthrosis)
Give me an example of gomphosis
Dentoalveolar articulation
Where do we have gomphosis
Between roots of teeth and their sockets
Which type of tissue is gomphosis
Dense irregular connective tissue
What type of movement is gomphosis
Synarthrosis
What type of movement can produce an cartilaginous joints?
Which are the 2 types of cartilaginous joints?
Allow little movement( Amphiarthrosis or Synarthrosis )
Synchondrosis
Symphysis
Synchondrosis is connected with which type of cartilage ?
Type of movement
Where
Hyaline cartilage
Immovable
1st rib and sternum
Symphysis is connected with what?
Type of movement
where
Between bone: flat disc of fibrocartilage
Amphiarthrosis
Midline of body: intervertebral disc, joint between manubrium + body sternum+ pubic symphisis
What type of movement is a synovial joints? What is the role
Type of tissue in the synovial membrane and in fibrous capsule?
Diarthrose
Reduce friction +absorb shock
Fibrous capsule: dense irregular connective tissue
Synovial membrane : arreolar connective tissue, macrophage (inner)
How many layers has articular capsule?
2 layers
Fibrous capsule and inner synovial membrane
What are the components of the synovial fluid
Hyaluronic acid secreted by synoviocytes and interstitial fluid from plasma
What is the function of articular capsule?
Reduce friction and help nourish the avascular articular cartilage
Bring nutrient and oxygen to the chondrocytes of the articular cartilage
Labrum is
Fibrocartilaginous lip
Shoulder and hip
Example of synovial joints
Ribs to sternum except 1 st rib
