Which plane of the body divides it into anterior (front) and posterior (back) halves?
Answer: Frontal (coronal) plane
The frontal (coronal) plane divides the body into anterior and posterior sections and is the plane in which abduction and adduction movements occur.
The gluteus maximus is the primary muscle responsible for which movement at the hip?
Answer: Hip extension
The gluteus maximus is the largest and most powerful hip extensor, critical for activities like rising from a chair, climbing stairs, and sprinting.
What type of joint is the glenohumeral (shoulder) joint?
Answer: Ball-and-socket joint
The glenohumeral joint is a ball-and-socket joint allowing the greatest range of motion of any joint in the body across multiple planes.
During a squat, which muscle group acts as the primary knee extensor?
Answer: Quadriceps femoris
The quadriceps femoris (rectus femoris, vastus medialis, lateralis, and intermedius) are the primary knee extensors active during the ascending phase of a squat.
The term 'valgus' at the knee refers to:
Answer: Inward angulation of the knee (knees cave medially)
Knee valgus describes medial collapse of the knee joint, a common movement fault associated with increased ACL injury risk, often corrected in kinesiological assessments.
Which anatomical term describes movement away from the midline of the body?
Answer: Abduction
Abduction is movement of a limb away from the body's midline, such as raising the arm laterally or spreading the legs apart.
