Final answer:
The main muscles of the anterolateral neck are the sternocleidomastoid and the three scalene muscles, which include the anterior, the middle (longest), and the posterior (smallest) scalene.
Step-by-step explanation:
The main muscles of the anterolateral neck are the sternocleidomastoid muscle and the three scalene muscles. The sternocleidomastoid is a significant muscle that laterally flexes and rotates the head, contributing to the flexion of the head when both sides work together. It is easily palpable when you turn your head side to side. The scalene muscles, consisting of the anterior scalene, the middle scalene (the longest scalene muscle, located between the anterior and posterior scalenes), and the posterior scalene (the smallest), work in concert to flex, laterally flex, and rotate the head, as well as aid in deep inhalation. These muscles are crucial for various head movements and contribute to neck stability and respiratory functions.
The main muscles of the anterolateral neck are the sternocleidomastoid muscle and the three scalene muscles. The sternocleidomastoid muscle is responsible for laterally flexing and rotating the head, while the scalene muscles work together to flex, laterally flex, and rotate the head, as well as contribute to deep inhalation.
