The cricothyroid muscle is the only tensor muscle of the larynx aiding with phonation. It is innervated by the superior laryngeal nerve. It is innervated by the superior laryngeal nerve. Its action tilts the thyroid forward to help tense the vocal cords , thus increasing the pitch of the voice.
Thyroid disease is a medical condition that affects the structure and/or function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.

Like the nervous system proposal increased muscle contractions eventually evoke muscle fiber fatigue, weakness, and finally degradation, which are characteristic symptoms of TM. There is evidence to support both theories; it has been suggested that toxic levels of thyroxine may ultimately attack muscle fibers directly and indirectly by the ...
The posterior cricoarytenoid muscle receives motor innervation from (the anterior division of) the recurrent laryngeal nerve (itself a branch of the vagus nerve (CN X)). [2] [5] Different parts of the muscle (such as the medial and lateral muscle bellies) are often innervated by separate branches. [2] There may be 1-6 branches, but are usually 2-3.
The cricothyroid joint (or articulation) is a joint connecting the cricoid cartilage and the thyroid cartilage. It plays a key role in adjusting human voice pitch by changing the tension of the vocal cords .
Typical symptoms are abnormal weight gain, tiredness, constipation, heavy menstrual bleeding, hair loss, cold intolerance, and a slow heart rate. [48] Iodine deficiency is the most common cause of hypothyroidism worldwide, [ 53 ] and the autoimmune disease Hashimoto's thyroiditis is the most common cause in the developed world. [ 54 ]
