What is tendonitis?
This condition is characterized by inflammation of a tendon
200
What are synchondroses and symphysis?
These are the two types of Cartilaginous Joints.
200
What is multiaxial?
Means movement can occur around all three axes and along all three body planes: frontal, sagittal, and transverse.
200
What is axon terminal, synaptic cleft, and sarcolemma of muscle fiber?
These are the three structural components of a neuromuscular junction
200
What is effort?
A component of the lever system defined as force applied to a lever to move a resistance.
200
What is fibromyalgia?
This is a mysterious chronic pain syndrome of unknown cause.
300
What are sutures, syndesmoses, and gomphoses?
Three types of Fibrous Joints.
300

300
What is epimysium, perimysium, and endomysium?
Connective tissue that holds fibers of skeletal muscle together in order from external to internal.
300
What is a second- class lever?
Resistance (load) is between fulcrum and effort.
300
What is Duchennes Muscular Dystrophy?
The most common form of muscular dystrophy?
400
What are plane, hinge, pivot, condylar, saddle, and ball & socket (pick two)?
Two of the six types of synovial joints.
400
What is knee joint?
The largest and most complex joint in the body. Primarily acts as a hinge but also permits some medial and lateral rotation.
400
What is myofibrils?
A contractile, rod shaped organelle that makes up more than 80% of the sarcoplasm.
400
What are third-class lever?
In this lever, effort is between the resistance and the fulcrum.
400
What is Dislocation?
Luxation and subluxtion are examples of this joint injury?
500
What is syndesmoses?
In this type of Fibrous joint, the bones are connected exclusively by ligaments and is amphiathrosis.
500
What is carpometacarpal joints of the thumbs?
An example of a saddle joint
500
What is sliding filament model?
Concentric contraction that is initiated by release of calcium ions which are powered by ATP. During contraction, myosin heads bind to actin, detach and bind again to propel thin filaments toward the M line.
500
What is MA>1 ?
Lever produces more force, but less speed and distance, than force exerted on it.
500
What is Bursitis?
Housemaid's knee and students elbow are examples of this condition
