Which joint type allows the greatest range of motion in multiple planes?
Answer: Ball-and-socket joint
Ball-and-socket joints, such as the hip and shoulder, allow multiplanar movement including flexion, extension, rotation, and circumduction.
The quadriceps femoris group is composed of how many muscles?
Answer: Four
The quadriceps femoris consists of four muscles: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.
Which structure connects muscle to bone?
Answer: Tendon
Tendons are dense connective tissue structures that attach skeletal muscle to bone and transmit contractile forces.
During a lateral lunge, which plane of motion is primarily involved?
Answer: Frontal
A lateral lunge involves side-to-side movement, which primarily occurs in the frontal plane.
Which muscle group is the primary antagonist to the quadriceps during knee extension?
Answer: Hamstrings
The hamstrings are the primary antagonists to the quadriceps because they oppose knee extension by performing knee flexion.
The rotator cuff is composed of which four muscles?
Answer: Supraspinatus, infraspinatus, teres minor, subscapularis
The rotator cuff consists of the supraspinatus, infraspinatus, teres minor, and subscapularis, which stabilize the glenohumeral joint.
