Voice production is a complex and coordinated process that involves the interplay of many different muscles. Here are some of the main muscles involved in voice production:
Laryngeal muscles: These muscles are located in the larynx, or voice box, and play a key role in voice production. The cricothyroid muscle, thyroarytenoid muscle, and lateral cricoarytenoid muscle are among the laryngeal muscles that control the tension and length of the vocal cords.
Diaphragm: The diaphragm, located at the bottom of the thorax, is a large muscle that controls breathing. It plays an important role in voice production by helping to regulate the flow of air to the larynx.
Intercostal muscles: These muscles are located between the ribs and play a role in breathing. They help to control the movement of the ribcage, which can affect the flow of air to the larynx and thus, voice production.
Abdominal muscles: The abdominal muscles, such as the rectus abdominis, help to control the movement of the abdomen and the flow of air to the larynx.
Sternocleidomastoid and scalene muscles: These neck muscles help to control the position of the neck, which can affect the ease and comfort of voice production.
Trapezius muscle: This muscle, located in the back, helps to control the movement of the shoulder and neck, which can affect the ease and comfort of voice production.
Suprahyoid muscles: These muscles are located above the hyoid bone and play a role in swallowing and speech. The geniohyoid and mylohyoid muscles, for example, help to control the position of the hyoid bone, which can affect the ease and comfort of voice production.
Infrahyoid muscles: These muscles are located below the hyoid bone and play a role in swallowing and speech. The omohyoid, sternohyoid, and thyrohyoid muscles, for example, help to control the position of the hyoid bone, which can affect the ease and comfort of voice production.
Pharyngeal muscles: These muscles are located in the pharynx and play a role in swallowing and speech. The pharyngeal constrictor muscles, for example, help to control the size and shape of the pharynx, which can affect the ease and comfort of voice production.
Tongue muscles: The tongue muscles play a key role in speech and voice production. The genioglossus, hyoglossus, styloglossus, and palatoglossus muscles, for example, help to control the movement and position of the tongue, which can affect the clarity and intelligibility of speech and voice.
Lips: The muscles of the lips, such as the orbicularis oris, help to control the movement of the lips, which can affect speech and voice production.
Cheeks: The muscles of the cheeks, such as the buccinator, help to control the movement of the cheeks, which can affect speech and voice production.
Jaw: The jaw is controlled by the temporalis, masseter, and lateral pterygoid muscles, among others. These muscles help to control the movement of the jaw, which can affect speech and voice production.
Soft palate: The muscles of the soft palate, such as the tensor veli palatini and levator veli palatini, help to control the movement of the soft palate, which can affect speech and voice production.
It's important to remember that voice production is a complex and coordinated process that involves the interplay of many different muscles. Understanding the role of each muscle in voice production can help us to better understand the nature of voice and to improve outcomes for individuals with voice difficulties.
