What muscles arise from pharyngeal arch 2?

Muscles of Mastication
Muscles of Facial Expression, Posterior Digastric, Stylohyoid, Stapedius
Muscles of the Tongue
Pharyngeal Musculature

The correct answer is: Muscles of Facial Expression, Posterior Digastric, Stylohyoid, Stapedius

Muscles arising from pharyngeal arch 2 include the muscles of facial expression, specifically the muscles of the posterior belly of the digastric, stylohyoid, and stapedius. These muscles are derived from the second pharyngeal arch during embryonic development. They play important roles in facial expressions, swallowing, and movement of the stapes bone in the middle ear. Muscles of mastication (Option A) are derived from the first pharyngeal arch, while the muscles of the tongue (Option C) are mainly derived from occipital myotomes. Pharyngeal musculature (Option D) is derived from various pharyngeal arches but not specifically from pharyngeal arch 2.
