Which muscle originates from the infraspinous fossa?

Explanation:
The muscle that starts from the infraspinous fossa is the infraspinatus. The infraspinous fossa is the hollow on the back of the scapula just below the spine, and the infraspinatus originates there before it travels to the greater tubercle of the humerus to help externally rotate the shoulder. The other muscles don’t originate from this fossa: trapezius comes from the skull and along the spine to the scapula; levator scapulae arises from the upper cervical transverse processes and inserts on the superior angle of the scapula; subscapularis originates from the subscapular fossa on the anterior surface of the scapula.
