Superficial Neck Muscles & Identifying Structure Practice

This video tutorial explores the muscles of the anterior neck, focusing on the deep, intermediate, and hyoid layers. It covers the identification and functions of various muscles, including the trapezius, levator scapulae, platysma, sternocleidomastoid, and others. The video also discusses muscle origins, insertions, and their roles in facial expressions and neck movements. Additionally, it highlights the blood supply and innervation of these muscles, providing a comprehensive understanding of their anatomy and physiology.

What movements are produced by the contraction of the sternocleidomastoid muscle?

Discuss the role of the scalene muscles in relation to the brachial plexus.

What is the anatomical relationship between the omohyoid muscle and the sternocleidomastoid?

Describe the innervation of the platysma muscle.
