Explanation: 

Detailed explanation-1: -In all fetuses studied, the stylopharyngeus, styloglossus and stylohyoid muscles originated from Reichert’s cartilage, which gives rise to the temporal styloid process.

Detailed explanation-2: -The stylohyoid muscle originates from the posterior and lateral surface of the styloid process of the temporal bone, near the base. Passing inferior and anterior, it inserts into the body of the hyoid bone, at its junction with the greater cornu, and just superior to the omohyoid muscle.

Detailed explanation-3: -Embryologically it developed from the second pharyngeal/brachial arch called as the Reichert’s cartilage because it is of cartilaginous origin. The styloid process provides attachments of two ligaments stylohyoid and stylomandibular ligaments and three muscles stylopharyngeus, stylohyoid and styloglossus muscles.
