GC Anatomy & Physiology for Gyrotonic Practice 2

Question 1

Which anatomical plane divides the body into anterior (front) and posterior (back) halves?

Accepted Answer

Frontal (coronal) plane

Answer

The frontal (coronal) plane divides the body into anterior and posterior sections and is the plane in which lateral flexion and abduction/adduction movements occur.

Question 2

The rotator cuff, which stabilizes the glenohumeral joint during Gyrotonic upper-body work, consists of how many muscles?

Accepted Answer

4

Answer

The rotator cuff is composed of four muscles — supraspinatus, infraspinatus, teres minor, and subscapularis — commonly remembered by the acronym SITS.

Question 3

The psoas major, a deep core muscle emphasized in Gyrotonic practice, is best known for which primary function?

Accepted Answer

Hip flexion

Answer

The psoas major is the primary hip flexor, connecting the lumbar vertebrae to the lesser trochanter of the femur and playing a critical role in core stability and spinal alignment.

Question 4

Which sensory receptors embedded within muscle tissue are primarily responsible for detecting changes in muscle length, forming the basis of proprioception?

Accepted Answer

Muscle spindles

Answer

Muscle spindles are sensory receptors located within muscle fibers that detect changes in muscle length and the rate of stretching, providing critical proprioceptive feedback to the nervous system.

Question 5

The hip joint, which is central to many Gyrotonic movements, is formed by which bones?

Accepted Answer

Head of the femur and acetabulum of the pelvis

Answer

The hip joint is formed by the head of the femur articulating within the acetabulum, a cup-shaped socket formed by the fusion of the ilium, ischium, and pubis.
