Which class of lever has the fulcrum located between the effort and the load?
Answer: First-class lever
A first-class lever has the fulcrum (joint) between the effort (muscle) and the load, as seen in head nodding on the atlanto-occipital joint.
The gastrocnemius muscle performs which combination of actions?
Answer: Knee flexion and plantar flexion
The gastrocnemius crosses both the knee and ankle, producing knee flexion and plantar flexion.
Which term describes a muscle that assists the prime mover by performing the same action?
Answer: Synergist
A synergist assists the agonist (prime mover) in producing the same joint movement.
The rotator cuff muscle that performs internal rotation of the glenohumeral joint is the:
Answer: Subscapularis
The subscapularis is the only rotator cuff muscle that internally rotates the shoulder; the others externally rotate.
Lateral deviation of the spine is called:
Answer: Scoliosis
Scoliosis is an abnormal lateral curvature of the spine, often with a rotational component.
Which movement decreases the angle between two body segments?
Answer: Flexion
Flexion decreases the angle at a joint, bringing the two segments closer together.
The tensor fasciae latae (TFL) primarily assists with which hip movement?
Answer: Hip flexion, abduction, and internal rotation
The TFL assists with hip flexion, abduction, and internal rotation, and also tenses the iliotibial band.
