MUSCULUS STERNOTHYREOIDEUS Meaning and
Definition
-
The musculus sternothyreoideus, also known as the sternothyroid muscle, refers to one of the muscles located in the region of the neck. It is a thin, paired muscle that is situated deep within the superficial layers of the neck and is part of the infrahyoid muscle group.
The musculus sternothyreoideus originates from the manubrium of the sternum, specifically from the posterior surface, and extends superiorly towards its insertion point at the thyroid cartilage. It is important to note that this muscle is bilateral, meaning it exists on both sides of the neck.
The main function of the musculus sternothyreoideus is to aid in the movements of the larynx and hyoid bone during swallowing and speaking. It works synergistically with other muscles in the neck to ensure the proper functioning of these actions.
In terms of innervation, the sternothyroid muscle receives its nerve supply from the ansa cervicalis, a loop of nerves originating from the cervical spinal nerves. This innervation allows for the motor control of the muscle.
Overall, the musculus sternothyreoideus plays an essential role in neck movements related to swallowing and speaking. Its location and bilateral nature make it an integral component of the neck musculature.
