Larry Page Has 'Hashimoto's Thyroiditis' Disease, And It May Have Impacted His Voice He says that his doctors don't really understand what happened to his vocal cords. So, he started to do some research on his own. The vocal cord nerves run through the thyroid, so he started looking there for answers. In 2003, Page was diagnosed with Hashimoto's thyroiditis. He describes it as a fairly common benign inflammatory condition of the thyroid which causes me no problems.. He really downplayed Hashimoto's role in his letter.

Vocal Cord Disorders The vocal cords are two bands of elastic muscle tissue. They are located side by side in the voice box (larynx) just above the windpipe (trachea). Like other tissues in the body, vocal cords can be strained and damaged. Vocal cords are also subject to infections, tumors and trauma. When you are silent, the cords remain open. They create an airway through which you breathe.

Medical Definition of Vocal cord paralysis Medical Definition of Vocal cord paralysis. Vocal cord paralysis: Inability of one or both vocal folds (vocal cords) to move. The paralysis is usually due to damage to the nerves going to the vocal cords or due to damage to the brain itself. In more technical terms, vocal cord paralysis may result from lesions in the nucleus ambiguus or its supranuclear tracts in the brain, the main trunk of the vagus nerve, or the recurrent laryngeal nerves (which supply the larynx.

- About Laryngoscopy. The larynx, or voice box, is the organ that produces voice. Found inside the neck, right at the top of the windpipe, or trachea, it contains two bands of tissue called vocal cords, or vocal folds. When we breathe, the vocal cords spread apart so that air can pass into and out of the lungs.

Overview Posterior to the larynx is the esophageal inlet. Video courtesy of Dr. Ravi Elluru. The vocal folds, also known as vocal cords, are located within the larynx (also colloquially known as the voice box) at the top of the trachea. They are open during inhalation and come together to close during swallowing and phonation.

- Historical Examples. 1  Like the other low castes they entertain a special veneration for Devi. 2  Then Birbal told them all that they must follow him to the temple of Devi in the wood. 3  In the sanctum was Devi, a large black figure with ten arms. 4  Conan swept up the Devi in his arms, and she did not resist. The People of the Black Circle Robert E. Howard He has not told anyone that it was the Devi who was kidnapped.

Vagus Nerve Anatomy Gross Anatomy. The vagus nerve is the longest cranial nerve. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body. It contains somatic and visceral afferent fibers, as well as general and special visceral efferent fibers.(See Table 1, below.).he recurrent laryngeal nerve is also known as the inferior laryngeal nerve. The right nerve branches from the vagus at the root of the neck around the right subclavian artery. It courses superiorly in the tracheoesophageal groove to enter the larynx between the cricopharyngeus and the esophagus.

Vocal folds Vocal folds. The vocal folds, also known commonly as vocal cords or voice reeds, are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation. Open when breathing and vibrating for speech or singing, the folds are controlled via the vagus nerve.

Causes A stroke interrupts blood flow in your brain and may damage the part of your brain that sends messages to the voice box. Tumors. Tumors, both cancerous and noncancerous, can grow in or around the muscles, cartilage or nerves controlling the function of your voice box and can cause vocal cord paralysis. Viral infections.

Designed for Communication The Vocal Cords. Your vocal cords are the source of the sounds that emanate from your larynx. Each of your two vocal cords is constructed of a tough, fibrous strand-the vocal ligament-which forms the free upper and inner edge of the vocal cord.he arytenoid cartilages, which anchor the vocal cords at the rear of your larynx, play a major role in tightening and moving your vocal cords in and out to vary the pitch of the sounds you make. A fold of tissue, called the ventricular fold, lies directly above your vocal cords.

The Vagus Nerve (CN X) The vagus nerve innervates: 1  Laryngopharynx – via the internal laryngeal nerve. 2  Superior aspect of larynx (above vocal folds) – via the internal laryngeal nerve. 3  Heart – via cardiac branches of the vagus nerve. 4  Gastro-intestinal tract (up to the splenic flexure) – via the terminal branches of the vagus nerve.

ThyroidGland and the Voice The vocal cords run from the thyroid cartilage at the front to the arytenoid cartilages, which sit on the back of the cricoid ring. Rotation of the arytenoids allows the cords to be brought together or apart, and movement between the thyroid and cricoid cartilages allows them to be stretched or relaxed.

Overview Vocal cord paralysis occurs when the nerve impulses to your voice box (larynx) are interrupted. This results in paralysis of your vocal cord muscle. Vocal cord paralysis can affect your ability to speak and even breathe. That's because your vocal cords, sometimes called vocal folds, do more than just produce sound.

Cranial Nerves originate in brain and spinal cord and have cranial AND spinal branches. Each cranial branch joins a vagus nerve and carries impulses to muscles of soft palate, pharynx & larynx. Spinal branch descends into neck & supplies motor fibers to trapezius and sternoclediomastoid. hypoglossal.

Recurrent laryngeal nerve The recurrent laryngeal nerve is a branch of the vagus nerve that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles. There are two recurrent laryngeal nerves, right and left, in the human body. The right and left nerves are not symmetrical, with the left nerve looping under the aortic arch, and the right nerve looping under the right subclavian artery then traveling upwards. They both travel alongside of the trachea. Additionally, the nerves are one

Voice and Swallowing Disorders Vocal Fold Paralysis. The vocal cords are two elastic bands of muscle tissue located in the voice box (larynx) directly above the windpipe (trachea). These cords allow you to speak because when air held in the lungs is released and passed through the closed vocal cords, it causes them to vibrate. When you are not speaking, the vocal cords remain apart so you can breathe. Vocal cord paralysis occurs when one or both of the vocal cords (vocal folds) do not open or close properly. The paralyzed cord or cords remain open, leaving the airway passage and the lungs unprotected. The condition makes it difficult to swallow or cough because food or liquids slip into the trachea and lungs.

What are Cervical Nerves? Cervical nerves are spinal nerves from the first seven vertebrae of the spinal cord. These seven vertebrae, called C1 through C7, begin at the base of the skull and make up the cervical spine in humans and most other mammals. Cervical nerves stem from the first seven vertebrae, C1-C7, of the spinal cord in your neck. 2  Cervical nerves can affect motor function in both the upper and lower body.

Recurrent laryngeal nerve Arches 4 and 6 produce the laryngeal cartilages. The nerve of the sixth arch becomes the recurrent laryngeal nerve. The nerve of the fourth arch gives rise to the superior laryngeal nerve. The arteries of the fourth arch, which project between the nerves of the fourth and sixth arches, become the left-sided arch of the aorta and the right subclavian artery.

Vagus nerve stimulation The vagus nerve is one of the cranial nerves, meaning a nerve that is connected directly to the brain. Output nerve fibres control muscles responsible for swallowing, coughing and voice sounds. Input nerve fibres transmit sensations and electrical feedback from the heart, lung, stomach and upper bowel to the brain.bout 80% of the nerve fibres in the left vagus nerve are input fibres transmitting, from the body to the brain, and the output fibres have minimal heart connections, making the left vagus nerve a suitable wire into the brain.

Chapter 6 - Brain Stem Organization The pharynx and larynx. Patients with cranial nerve damage often have problems with their voice or with swallowing. The nucleus ambiguus is the location of the majority of the motor neurons to the larynx, pharynx and soft palate. These fibers travel with the vagus and, to a lesser extent, the glossopharyngeal nerve.
