- Anatomy
- Synovial
Joints
- Synovial
Membrane(synovium)
- Produces a synovial fluid
- lubrication, free movement,
and nutrition of the cartilage
since it doesn’t have a blood
supply
- viscous,
non-Newtonian fluid
found in the cavities
of synovial joints.
- hyaluronic
acid
- lubricin
- collagenases
- proteinases
- They allow free movement
- It doesn’t ossify, except
under certain pathological
conditions.
- Articular surfaces
of the bone
- Hyaline
cartilage(articular
cartilage)
- The entire joint cavity is
covered by a dense fibrous
tissue capsule
- Certain areas of
the dense
fibrous tissue
capsule are
thickened
occasionally by
capsular
ligaments
- Outside of the capsule,
extra-capsular
ligaments are found
- Intra-capsular (intra-articular)
structures can be found;
meniscus, labrum, tendons,
and disc.
- A synovial
sheath .
- a tubular bursa
that surrounds a
tendon.

- 5 metacarpals
- Arteries
- Superficial Palmar Arch
- mainly by ulnar a.)
- is superficial to the long flexor
tendons just deep to the palmar
aponeurosis. On the lateral side
of the palm, the arch
communicates with the superficial
br. of the radial artery.
- Deep Palmar Arch
- mainly by radial a
- penetrates the origin of the hypothenar muscles;
access the deep plane of the palm to anastomose
with the deep palmar arch derived from the radial
artery.

2/3 of the palm &
dorsum + medial

the head of ulna from the

two rows of
carpal bones

, adduction , flexion and particularly
extension
- Carpometacarpal Joint
- Between the distal row of carpal
bones and proximal end of the
metacarpal bones .
- more stability than mobility.

- Between the distal heads of the
metacarpals and the proximal
phalanges of the digits .
- flexion , extension , abduction ,
adduction , circumduction and
limited rotation .
- Interphalangeal Joints

- Between the phalanges of the hand .
- flexion and extension

weight-bearing joints, such as
the hips and knees.

- Pathophysiology
- Autoreactive T cells
are activated by
antigen-presenting
cells presenting
self-peptide to CD4
cells.
- Macrophages exacerbate the
disease by secreting TNF
usually found in rheumatoid
synovial tissues, resulting in
cartilage destruction via effects
on chondrocytes
- Rheumatoid
factors are
released as a
consequence to
the activation
of B cells.
- Macrophages also release
the chemokine IL-8 which
recruit neutrophils that
cause more damages to
the tissues
- Inflammation
- Cartilage damage
and joint space
narrowing
- Bone erosion
- During the process of the
disease, cells are damaged
releasing anti-DNA. RF then
binds the DNA-anti-DNA
forming a complex that binds
and damages basement
membranes.
