Q

Synovial -joint frication-Reducing

A

1- Bursa : Flattented ,Fibrosis saces lined with synovial membrane contaning fluid
Ex: ligamint , muscle , skin tendone or bone rube togather
2- Tendon sheath : elongate bursa compeletely around tendone

Q

💘
Stability of Synovial joint

A

Articular surfaces – shape determines what
movements are possible • Ligaments – unite bones and prevent excessive or
undesirable motion
Muscle tendons across joints are the most important
stabilizing factor • Tendons are kept tight at all times by muscle tone

Q

💘
Synovial joint Movement

A

Muscle attachment across a joint
• Origin – attachment to the immovable bone • Insertion – attachment to the movable bone
• Described as movement along transverse, frontal, or
sagittal planes

Q

💘
Synovial joint : Range of movement

A

Nonaxial – slipping movements only • Uniaxial – movement in one plane • Biaxial – movement in two planes • Multiaxial – movement in or around all three planes

Q

💘
Gliding Movement

A

One flat bone surface glides or slips over another similar
surface • Examples – intercarpal and intertarsal joints, and between
the flat articular processes of the vertebrae

Q

💘
Rotation (Synovial joint )

A

The turning of a bone
around its own long
axis • Examples:
• Between first two
vertebrae (C1 & C2) • Hip and shoulder
joints

17
Q

💘
Special Movement of (Rotastion )

A

Supination
and pronation • Inversion and
eversion
• Protraction
and retraction • Elevation and
depression
• Opposition

18
Q

💘

Types of Synovial Joints

A

Plane
Hinge
Pivot
Ball and socket
Eliposed
Saddle

19
Q

(Synovial joint) Plane joint
De .EX

A

Articular surface are essenastially flat
Allow only slibbing or gliding
Nonaxial joint

20
Q

Hinge joint (synovial joint )
Defenation and example

A

Cylinder projection
Flextion and extenation only
Motion single plane
Elbow and interphalange joint

21
Q

Pivot joint (synovial joint )

A

Rounded end of one
bone protrudes into a “sleeve,” or ring, composed of bone (and possibly ligaments) of another
Axis and dense proximal radioandulnar joint
Only unixial movement allowed

22
Q

Condyloid or ELLipsidal joint (Synovial joint )

A

Oval articular surface
of one bone fits into a complementary depression in another
• Both articular surfaces
are oval • Biaxial joints permit
all angular motions • Examples: radiocarpal
(wrist) joints, and
metacarpophalangeal
(knuckle) joints
