depresses hyoid bone and fixes hyoid bone during opening of mouth
Omohyoid
The sternohyoid muscle, Omohyoid muscle, and Thyroid muscle are three muscles that are responsible for the depression of the hyoid bone.
The action of the omohyoid is to depress the hyoid. Its name derives from the Greek "omos" meaning shoulder, giving one of its attachments, and "hyoid", giving the other attachment - the hyoid bone. The function of the hyoid seems to be in voice variations. All mammals have them and there are arguments if primitive hominids used them as we do.
B. Omohyoid. The omohyoid muscle is not directly involved in the process of chewing or manipulating food in the mouth. It acts to depress and stabilize the hyoid bone in the neck.
The infrahyoid muscles, such as the sternohyoid, omohyoid, thyrohyoid, and sternothyroid muscles, are responsible for depressing the hyoid bone. These muscles help to lower the hyoid bone during swallowing and speaking.
The muscle that starts with the letter "o" is the orbicularis oris, which is a circular muscle surrounding the mouth. It is responsible for controlling lip movements and aiding in actions such as puckering, kissing, and smiling.
The muscle tissue's main function is to contract.
Thyrohyoid is a suprahyoid muscle and it depresses the larynx , it also helps in swallowing and deglutition , some Indian books state that is an elevator of the larynx , but most literature that i have read states it to be a depressor , other depressors of the larynx are omohyoid , sternohyoid and sternothyrohyoid.
attachements of muscle to muscle
the muscle are to move the bone.
to complete the function commanded by the brain
When a nerve does not signal a muscle, the muscle will not receive the message to contract and therefore will not move or function properly. This can lead to muscle weakness, paralysis, or loss of function in the affected area. It is important for nerve-muscle signaling to be intact for normal movement and function.
