Larynx

The larynx’s main function is to provide airway, protect thr bronchial tree and to allow phonation. When there are growths that develop on the structure, the function is compromised. Laryngeal Cancer is characterized as a disease where masses, cancer cells, begin to accumulate in the larynx. Laryngeal Cancer is a very rare type of cancer, according to cancerresearchuk, approximately twenty-four thousand of patients are diagnosed with Laryngeal Cancer in a year, which is relatively two to five percent of cancerous cases diagnosed in a given year. Laryngeal is categorized into four stages that are determined by how much the cancer cells have spread to other parts of the body. The higher the stage, the more the cancer has spread which induces…

Higuera, Valencia. “Throat Cancer.” Healthline.com, Healthline Media, 20 Dec. 2016, www.healthline.com/health/cancer-throat-or-larynx. Higuera's article on Healthline is about throat cancer, which consists of two categories: pharyngeal and laryngeal cancer (Higuera). The pharyngeal cancer is the pharynx, which is the hollow tube that runs from behind the nose to the top of the windpipe (Higuera). Laryngeal cancer is the larynx, which is your voice box (Higuera). The website offers various links…

The laryngeal muscles of the phonatory system are comprised of a group of both intrinsic and extrinsic muscles. Out of these two muscle groups, the placement of the extrinsic muscles are what confuse me the most. The extrinsic laryngeal muscles are further divided into suprahyoid and infrahyoid muscles. The suprahyoid muscles attach superiorly to the hyoid bone and elevate the larynx and hyoid bone, while the infrahyoid muscles attach inferiorly to the hyoid bone and depress the larynx and the…

Voicing When we inhale, air passes into our lungs. Between our pharynx and trachea, each of us have a pair of vocal folds that separate when we do this. This process is called abduction. We use a small intrinsic muscle in our larynx that pulls the vocal folds apart allowing and allows air to move into our lungs. This causes the glottis to open from the back to the front, and the vocal folds wave from the back to the front. The posterior cricoarytenoid muscle is responsible for this…

Gillian Bianchi and Sarah Collins February 10, 2016 Dr. Leydon SLP-585-A Larynx Dissection 1. When we began we saw the trachea, the aditus, vestibule, and the aryepiglottic folds. a. The trachea is the tube-like structure that attaches to the cricoid, and brings oxygen into the lungs. b. The esophagus is the structure on the posterior side of the structure, this structure brings the bolus into the stomach. c. The aditus is the opening at the top of the structure d. The vestibule e. The…

There may be a delayed swallow response from a few to many seconds after the patient attempt to swallow. Timing and coordination of the oral-pharyngeal structures may be impaired. An overall decrease in pharyngeal strength, causing excessive pooling in the valleculae and pyriform sinuses, may be present. The soft palate may be too weak to close the velopharyngeal port to prevent material from entering the nasal passages. The suprahyoid muscles may be weak, preventing good elevation of the hyoid…

Depending on severity and setting, laryngospasms and bronchospasms can be either non life-threatening or life-threatening (Drugs.com, 2016). The treatments for them both involve interventions such as positive-pressure breathing and medications, such as steroids. Preventions only apply to the bronchospasms that occur in a normal setting outside of the operating room (Drugs.com, 2016). Laryngospasm A laryngospasm is a brief spasm of the vocal cords that temporarily make it difficult to…

started just cranial to the hairs on the chin of my pig and ended cranial to the upper limbs of the pig. I then used my scalpel to cut a horizontal cut from the initial incision and pulled the skin and muscle away from the internal structures that I was required to locate in the neck. The internal structures that I had to locate in the neck were the hyoid apparatus, larynx, thyroid gland, trachea, and thymus gland. The hyoid apparatus is a small group of bones located cranial to the larynx that…

This occurs because of the cellular makeup of the vocal folds. The superficial and upper layers are more pliable. Vibrations occur when air flows through the trachea and larynx. The vibrations consist of lateral and medial movements that produce the mucosal wave as the vibrations travel from lower to upper vocal folds. There is a slight time lag between the approximation and separation of lower and upper edges of vocal folds. This is called the vertical phase difference. The vocal folds close…

it protects the nasal passage by directing a portion of the substance to the mouth. The uvula hangs fro the end of the soft palate, in humans. The placement of the velum all depends on what sound you as a singer. If you have a high, lifted velum your sound will be more legit or classical. A good way to achieve this sound is by whimpering like a dog, or by acting like a queen and saying “ I am the queen” works well, this one also lowers the larynx. Having a middle or medium soft palate comes from…
