Question 1
Which plane of motion divides the body into front and back halves, and what movement occurs within it?
Answer: The frontal (coronal) plane divides the body into anterior and posterior halves; movements such as abduction, adduction, and lateral flexion occur in this plane.
Question 2
A bicep curl occurs primarily in which plane of motion?
Answer: A bicep curl occurs primarily in the sagittal plane, which divides the body into left and right halves and involves flexion and extension movements.
Question 3
Which axis of rotation is associated with movements occurring in the transverse plane?
Answer: The longitudinal (vertical) axis runs head to foot and is associated with transverse plane movements such as rotation.
Question 4
What is the term for the imaginary point around which a body segment rotates during movement?
Answer: The axis of rotation (also called the fulcrum in lever mechanics) is the imaginary point or line around which a body segment rotates.
Question 5
What type of joint is the glenohumeral (shoulder) joint, and what makes it highly mobile but unstable?
Answer: The glenohumeral joint is a ball-and-socket synovial joint. Its mobility comes from a shallow glenoid fossa relative to the large humeral head, which sacrifices bony stability and relies on soft tissue (rotator cuff, labrum, ligaments) for support.
