Question 1

In biomechanics, what term describes the rotation of a bone around its own long axis?

Accepted Answer

Axial rotation

Answer

Axial rotation (also called spin) is the movement of a bone rotating around its own longitudinal axis, such as internal or external rotation of the femur.

Question 2

Which plane of motion divides the body into anterior and posterior halves and is associated with abduction and adduction movements?

Accepted Answer

Frontal plane

Answer

The frontal (coronal) plane divides the body into front and back halves, and movements in this plane include abduction, adduction, and lateral flexion.

Question 3

What type of muscle action occurs when a muscle produces force while lengthening?

Accepted Answer

Eccentric

Answer

Eccentric muscle action occurs when a muscle generates tension while being lengthened, such as the quadriceps controlling knee flexion during stair descent.

Question 4

The term 'osteokinematics' refers to which aspect of joint movement?

Accepted Answer

Observable gross motion of a bone in space

Answer

Osteokinematics describes the visible, gross movement of a bone in space (flexion, abduction, etc.) as observed from outside the body.

Question 5

During a squat, which joint action occurs at the hip during the descent phase?

Accepted Answer

Hip flexion

Answer

During squat descent, the hip undergoes flexion as the torso lowers toward the ground under controlled eccentric loading.
