|
Articulation
|
Place of contact between bones, between bone & cartilage, or between bones and teeth.
|
|
|
The scientific study of joints is called?
|
arthrology
|
|
|
Mobility vs. Stability:
Is the glenohumeral (shoulder)joint mobile or stable? |
1-This joint is very mobile but not very stable. (In contrast,The more stable the joint, the less movable it can be)
|
|
|
Synarthrosis
|
(joined together) is an immovable joint. (Classified as Functionally)
|
|
|
Amphiarthrosis
|
(around) slightly movable joint. (Classified as Functionally)
|
|
|
Diarthrosis
|
(two) freely moveable joint. (Classified as Functionally)
|
|
|
Name the ______ joint where bones are held together by dense regular connective tissue.
|
Fibrous joint
(Classified as Structurally) |
|
|
Cartilaginous
|
Bones are joined together by cartilage. (Classified as Structurally)
|
|
|
Joints
|
Place of contact between bones; sometimes movable & sometimes not.
|
|
|
Synovial Joint
|
(most common joint) Fluid filled, synovial cavity that separates the articulating surfaces of the bones & these articulating surfaces are enclosed w/in a capsule.
The bones are also joined by various ligaments. (Classified as Structurally) |
|
|
Name the three joints that are classified as functionally.
|
Synarthrosis
Amphiarthrosis Diarthrosis |
|
|
Kinesiology
|
Study of functional relationship of the skeleton, joints, muscles, & nerves. STUDY of MOVEMENT
|
|
|
What is the most immovable and the most stable joint in the body?
|
Sutures; Fibrous joint yet is synarthrosis (immobile)
|
|
|
Gomphosis
|
Fibrous synarthrotic joints (immobile) only found in tooth sockets (alveoli) in the maxilla.
|
|
|
Syndesmosis
|
Amphiarthrosis (slightly movable) Fibrous joint. Ex: Articulates between radius & ulna & between tibia and fibula.
|
|
|
Name two structures that are cartilaginous joints?
|
Synchondrosis-Hyaline Cartilage plate between bones.(Synarthrosis-immobile) & Symphysis-Firbocartilage pad btwn bones.(Amphiarthrosis-slightly movable)
|
|
|
Synarthrosis means?
|
Immovable joint
|
|
|
What word means slightly movable?
|
Amphiarthrosis
|
|
|
What three joints are classified as uniaxial?
|
Planar joint, Hinge joint, & Pivot joint
|
|
|
Planar Joint-uniaxial(diathrosis)
|
Flattened,slightly slides across one another. Ex:Intercarpal & Intertarsal joints, & Articulating processes of vertebrae.
|
|
|
Diarthrosis (freely movable) are found in what structural joint?
|
Synovial joint-Uniaxial (diarthrosis)
|
|
|
Permits angular movement in a single plane. Ex: Humeroulnar (elbow) joint
|
Hinge joint-Uniaxial (diarthrosis)
|
|
|
Pivot joint (diarthrosis)
|
Permits rotation only-Uniaxial Ex: Atlantoaxial joint
|
|
|
Uniaxial
|
One plane/one joint
|
|
|
Name the two biaxial joints
|
Condyloid Joint & Saddle Joint (Diarthosis-freely movable)
|
|
|
Biaxial
|
Two planes of motion
|
|
|
Condyloid joint
|
Oval articular surface on one bone closely interfaces w/ a depressed surface on another bone. Ex: Metacarpophalangeal (MP) joints (Diarthrosis-freely movable)
|
|
|
Saddle joint
|
Saddle-shaped articular surface on one bone closely interfaces w/ depressed surface on another bone. Ex:Articulation between carpal & first metacarpal bone (Diarthrosis-freely movable)
|
|
|
Ball & socket joint
|
Multiaxial (triaxial) Round head of one bone rests w/in a cup-shaped depression in another bone. Ex: Glenohumeral joint & coxal joint (diarthrosis-freely movable)
|
|
|
The articulating processes of the vertebrae are what type of joints?
|
Diarthrotic synovial gliding (Planar) joint
|
