Describe the development of the neck, including its anatomical boundaries, skin, and muscle origins.
Understand the Problem
The image describes the development of the neck, specifically its anatomical boundaries and the origins of its skin and muscles from cervical dermatomes and myotomes.
Answer
The neck extends from the cranium to the clavicles. Its skin is from cervical dermatomes C2-C6, and muscles like the sternocleidomastoid and trapezius originate from cervical myotomes.
The neck's anatomical boundaries are the base of the cranium superiorly and the suprasternal notch with the clavicles inferiorly. The skin of the neck comes from cervical dermatomes from the second to sixth cervical segments. The sternocleidomastoid, strap muscles, and trapezius originate from cervical myotomes.
