Joint reinforced by a combination of fibrous and cartilaginous connective tissues; permit slight to no movement.
|
Synarthroses
|
|
Joint stabilized with dense connective tissue. i.e: sutures of the skull and tibiofular joint
|
fibrous
|
|
Joint stabilized by various forms of cartilage. i.e: pubic symphsis, interbody joint of spine.
|
cartilaginous
|
|
Joint which possesses a synocial fluid-filled cavity; permits moderate to extensive movement.
|
synovial/diarthroses
|
|
Covers the ends of bones
|
articular cartilage
|
|
Connective tissue curtain. Outer portion provides support to bones and contains joint content.
|
joint capsule
|
|
Internal layer of joint capsule.
|
synovial membrane
|
|
Reduces friction in a joint, nourishes articular cartilage.
|
synovial fluid
|
|
Protects joints from excessive movement.
|
ligaments
|
|
In ________ joints the movement is more linear than angular and normally occurs secondarily. For example, flexion and extension of the wrist causes carpals to move up and down in response.
|
Arthrodial (Gliding)
|
|
A _________ joint has a uniaxial articulation, where articular surfaces allow motion only in one plane. For example, elbow, knee, talocrural and subtalar flexion and extension.
|
ginglymus (hinge)
|
|
A ________ joint also has uniaxial articulation but focuses on pronation and supination. Occurs in the transverse plane.
|
trochoid (pivot)
|
|
A ________ joint is a biaxial ball and socket joint. One bone with an oval concave surface is received by another bone with a oval convex surface.
|
condyloid (knuckle)
|
|
A ________ joint is a multiaxial or triaxial ball and socket joint. Example would be the hip.
|
enarthodial
|
|
A ________ joint is a unique triaxial joint where 2 reciprocally concave and convex articular surface move across one another. Examples of this would be the 1st carpometacarpal joint at the thumb and the sternoclavicular.
|
sellar (saddle)
|
|
Broken bones
|
fracture
|
|
complete separation of the two articular surfaces
|
dislocation
|
|
partial dislocation
|
subluxation
|
|
partial or complete tearing of fibers
|
sprain
|
|
overstretching of muscle fibers
|
strain
|
|
inflammation of a tendon
|
tendonitis
|
|
inflammation of the tendon sheath (membrane surrounding tendon)
|
tenosynovitis
|
|
inflammation of the synovial membrane
|
synovitis
|
|
inflammation of the bursa (provides lubrication between joints and bones)
|
bursitis
|
|
inflammation of the joint capsule
|
capsulitis
|
|
A series of segmented links that articulated together. Example, the pelvis, thigh, leg and foot; the wrist, forearm, elbow, arm and shoulder
|
Kinematic chains
|
|
In a ______ chain the distal end is fixed to something or weighted. The proximal segment is free to move.
|
closed
|
|
In a _____ chain the distal end is free to move.
|
distal
|
|
3 types of movement occur between curved joint surfaces where one surface is convex and one is concave. Name those three movements.
|
Roll, slide, spin
|
|
The ______ (close/open) packed position is the position of maximal congruency where the articular surfaces within the joint "fit" best.
|
close
|
|
The ______ (close/open) packed position occurs when ligaments and tendons are loose.
|
open
|
