40 Questions
Arthrology is the study of muscles and their functions.
False
Understanding impairments of joints is not important in kinesiology.
False
The design of a joint depends solely on the components and not on its function.
False
Joints designed for stability are different from joints designed for mobility.
True
Design complexity increases as functional demands decrease.
False
Synarthroses allow for a wide range of movement between bones.
False
Arthrokinematics and osteokinematics are among the objectives of studying arthrology.
True
Classification of joints based on movement potential is not relevant in arthrology.
False
Passive ROM involves maximum force by the extensors in middle range.
False
Degrees of freedom refer to the number of independent movements allowed at a joint.
True
Impure swing in osteokinematics involves pure back and forth movement around a fix pivot point in one plane.
False
The physiological barrier marks the end of the outer range of motion.
False
Joint play refers to the externally forced movement of one articular surface over another.
True
Active ROM involves maximum force by the extensors in inner range.
True
End feel is the underpressure experienced at the end of passive ROM.
False
Spin in osteokinematics involves rotation around a joint axis.
False
Connective tissues have the inherent ability to tolerate loads.
True
Stress is defined as the force applied per unit area.
True
Strain refers to the change in shape, length, or width of a structure.
True
The stress-strain curve has only one zone.
False
In the elastic or linear zone, the tissue returns to its original length or shape, and most of the energy used to deform the tissue is released once the deforming force is removed.
True
The load applied to a structure or material is always an external force.
False
The type of stress and strain that develops in human structures is independent of the nature of the material, type, direction, magnitude and rate and duration of the load that is applied, and the point of application of the load.
False
The stress-strain curve shown in the figure represents the tension generated by an excised ligament that has been stretched to a point of mechanical failure.
True
The articular surface of one bone in an ovoid joint is convex, and the other is concave.
True
In a saddle joint, both bones have paired convex and concave surfaces oriented at a 45° angle to each other.
False
Synovial fluid helps reduce friction in diarthrodial/synovial joints.
True
Articular cartilage covers the bones in diarthrodial/synovial joints.
True
Intraarticular discs or menisci are always present in diarthrodial/synovial joints.
False
Osteokinematics describes the motion between the articular surfaces of joints.
False
Compression is an example of an axial translatory force in joint kinetics.
True
Joint play is necessary for the articular surfaces to slide in the desired direction of bone movement.
True
Tissues that are elongated beyond their physiologic range eventually reach their yield point.
True
Plastic deformation of a tissue is recoverable when the deforming force is removed.
False
The anterior cruciate ligament is normally strained about 3-4% during common activities.
True
Most healthy tendons fail at about 8-13% beyond their prestretched length.
True
Plasticity is the physical behavior of an overstretched or overcompressed tissue.
True
In the plastic zone, microscopic failure has occurred and the tissue remains permanently deformed.
True
Increased strain in the plastic zone results in significant increased stress (tension).
False
The design of a joint is dependent solely on its function.
False
This quiz covers the classification, structure, and function of joints, providing a foundation for the study of kinesiology. Topics include joint design, arthrokinematics, osteokinematics, and properties/functions of materials in human joints.
