Muscles of the neck

Dr. Morton provides an in-depth analysis of the muscles in the cervical fascia, detailing their locations, actions, and innervations. The video covers the superficial fascia with the platysma muscle, the deep investing fascia with the sternocleidomastoid and trapezius muscles, the prevertebral fascia with the scalene muscles, and the pretracheal fascia with the infrahyoid muscles.
