Q

Name the three structural classifications of joints

A

FIBROUS, CARTILAGINOUS and SYNOVIAL

84
Q

SYNARTHROSES

A

Fibrous and cartilaginous joints. (1) the mating bones interconnect by fibrous tissue or cartilage, (2) there is no joint cavity, and (3) movement is absent or very limited.

85
Q

DIARTHROSES

A

Synovial joints. freely moveable.

86
Q

SUTURES and SYNDESMOSES are what type of joints?

A

fibrous joints.

87
Q

SUTURE

A

the union of two interdigitating bones by a thin fibrous layer of tissue.

88
Q

SYNOSTOSIS

A

the bony fusion of a suture.

89
Q

SYNDESMOSIS

A

the joining of two adjacent bones by ligamentous tissue with no bony interdigitation between the mating bones. (e.g. the interosseous membrane between the radius and ulna)

90
Q

SYMPHYSES and SYNCHONDROSES are what type of joints?

A

cartilaginous joints.

91
Q

SYMPHYSIS

A

unites two bones by a disc of fibrocartilage.

92
Q

AMPHIARTHROSIS

A

cartilaginous connections with slight
motion in all directions. (e.g. intervertebral joint
between vertebral bodies. also a symphysis)

93
Q

SYNCHONDROSES

A

two bones united by a region of hyaline cartilage. (e.g. The epiphyseal growth plates of developing long bones)

94
Q

4 characteristics of SYNOVIAL JOINTS

A

(1) a joint space which may or may not be divided by a fibrous interarticular disc or meniscus,
(2) a synovial membrane lining the joint cavity which produces synovial fluid for joint lubrication and nutrition,
(3) a fibrous joint capsule which may be 24
reinforced by joint ligaments, and
(4) a thin layer of articular cartilage, usually hyaline, without perichondrium covering the articular surfaces of the mating bones.

95
Q

6 types of SYNOVIAL JOINTS

A

1) Plane
2) Hinge
3) Pivot
4) Condyloid
5) Saddle
6) Ball and Socket

96
Q

CLOSE PACKED POSITION

A

The position in which these opposing joint surfaces approximate congruency. In this position, the joint is very stable and its joint capsule and ligaments are mostly tight. The joint is in its most efficient position for load bearing.

97
Q

LOOSE PACKED POSITION

A

The position where the joint capsule is most slack and the ligaments are most lax. In the loose packed position, the joint is considered to be unlocked and inefficient for load bearing. Joint mobilization and the determination of joint mobility are best performed in the loose packed position.

98
Q

PLANE JOINTS

A

(ARTHRODIAL JOINTS) Joints that have relatively flat articular surfaces that permit gliding movements in any plane.

99
Q

HINGE JOINTS

A

(GINGLYMUS JOINTS) Joints that have one concave articular surface and an opposing convex articular surface. They allow mainly uniaxial movement in the sagittal plane.

100
Q

PIVOT JOINTS

A

(TROCHOID JOINTS) Joints that have one concave articular surface, one convex surface. They allow mainly uniaxial joint rotation in the transverse plane.

101
Q

CONDYLOID JOINTS

A

(ELLIPSOID JOINTS) Joints that have an oval concave articular surface and an opposing oval convex articular surface. They allow biaxial movement in sagittal and frontal planes. Rotation is restricted by the curvature of the opposing joint
surfaces.

102
Q

SADDLE JOINTS

A

(SELLAR JOINTS) In this joint, each articular surface has a concave and convex surface. The plane of the concave surface is at a right angle to the plane of the convex surface. The position of the concave and convex surfaces on one articular surface is reversed on the opposing articular surface. This joint may permit biaxial or triaxial
movement.

103
Q

BALL AND SOCKET JOINTS

A

(ENARTHRODIAL JOINTS) Joints that have one concave articular surface and one convex articular surface. The curvature of each articular surface is
similar in all planes. These joints permit movements in all three cardinal planes (triaxial).

104
Q

CONCAVE/CONVEX RULE

A

convex on concave = gliding movement is opposite as the observed osteokinematic motion.
concave on convex = gliding movement is the same as the observed osteokinematic motion.

105
Q

LOAD

A

An external force is applied to any material, causing forces to develop within that material and the material to deform.

106
Q

STRESSES

A

The transmitting and resistive forces within the material as a result of an applied LOAD. Expressed as the applied force per area.

107
Q

STRAIN

A

The deformation resulting from an applied LOAD. Expressed as the change in size or angle as compared to the original configuration.

108
Q

TENSILE LOAD

A

the forces that pull away from a structure or object (e.g. pull of a tendon on a bone by a contracting muscle)

109
Q

TENSILE STRAIN

A

When the tensile stresses are greater than the resisting compressive stresses, causing the material to elongate.

110
Q

COMPRESSION LOAD

A

When forces act towards each other. (as when an intervertebral disc is compressed between adjacent vertebral bodies)

111
Q

COMPRESSIVE STRAIN

A

When the compressive stresses are greater than the tensile stresses, causing the material to be squeezed or compressed

112
Q

SHEAR LOAD

A

When forces act in parallel planes but in opposite directions (as in the tearing or cutting action of paper)

113
Q

SHEARING STRAIN

A

When the shear stresses are greater than the resistance of the material to shear, than these stresses cut or tear the material in a scissor-like
action.

114
Q

BENDING of bone, cartilage and other structures

A

When tensile stresses and strains are applied on

the convex side of the bending material and compressive stress and strain on the concave side.

115
Q

TORSIONAL STRAIN

A

Produced by rotational shear stress, resulting in the twisting of the material.

116
Q

What is FRICTION and what three things relate to its magnitude?

A

resists movement between contacting surfaces. Its magnitude is related to 1) the amount of force pressing the contacting surfaces together, 2) the amount of surface area in contact between surfaces, and 3) the surface texture of the materials in contact.

117
Q

TORQUE

A

(MOMENT) The force producing rotation about an axis in any lever. Occurs at a joint when muscle contraction produces a force that results in rotation at the joint. It is equal to the magnitude of the applied force times the perpendicular distance from the force to the axis of rotation.
