Larynx

Voice and hydration Human communication happens predominantly through voice. The larynx is susceptible to injury and disease. Titze (1988) proposed that the energy required to drive small-amplitude oscillation of the vocal folds depends on tissue biomechanical properties. Vocal fold hydration is supposed to promote ideal biomechanical characteristics of vocal fold mucosa, increased efficiency of vocal fold oscillation, and enhance voice quality. There is evidence that, as the body tries to…

scientists of the article investigated the effect of thymoquinone on lung carcinoma, larynx epidermoid carcinoma, colon adenocarcinoma, and pancreatic carcinoma. Thymoquinone was found to have both cytotoxic and apoptotic effects on the cancers. Cytotoxic means that it was toxic to some living cells. Apoptotic means that it could induce the cell to destroy itself. Thymoquinone showed a major effect on the cells tested. The larynx epidermoid carcinoma cancer cells were the most affected. They…

we breath Diagram that includes the major parts - trachea, lungs, diaphragm, epiglottis, larynx, vocal cords - and list the function(s) of each. trachea- wide hollow tube that connects to the larynx to the bronchi of the lungs lungs- taking in oxygen releasing carbon dioxide diaphragm- the muscle that separates the chest from the abdomen epiglottis-covers voice box cover food from entering windpipe. larynx-is the voice box it contains the vocal cords vocal cords-lets you talk Describe the…

Another important role the pharynx, taking place in the respiratory system. The pharynx also plays an important role in the respiratory system, as air from the nasal cavity passes through the pharynx on its way to the larynx and eventually the lungs, because the pharynx serves two separate jobs. The esophagus is a really simple tube that is used for transportation starting at the mouth continuing to the stomach. In reality when we actually swallow what we are truly doing…

during dental treatment for good posture and to reduce back pain. It is advised to perform dental treatment under local anesthesia, because general anesthesia poses certain complications due to anteriorly placed epiglottis, small nasal pharynx and larynx, difficulty in intubation, lumbar lordosis, narrowing of spinal cord and small chest. It is important for dental professionals, to recognize risk factors and potential complications before sedation or anesthesia. When dental treatment is decided…

What can be done to protect yourself from toxic metal fumes during the welding process? It's been long known that not protecting yourself from such dangerous fumes comes at a very high price on your health. Acute and prolonged exposure may have very negative consequences. Fortunately there are many ways to protect your health and enjoy a prosperous long life. Without the proper protection, overexposure to hazardous fumes can show acute or chronic health effects. Acute effects appearing…

The next journal article called, “Immediate Effect of Laryngeal Manual Therapy in Dysphonic Individuals”, focused on investigating the immediate effect of Laryngeal Manual Therapy (LMT) in musculoskeletal pain, in voice, and sensations of individuals with and without functional dysphonia. Individuals with this type of dysphonia suffer from pain of extrinsic laryngeal muscles and postural changes. Typically, the treatment for this type of dysphonia included laryngeal massages and postural changes…

According to the Health Effects of Cigarette Smoking (2015), Smoking can cause cancer within all human body, such as bladder, Blood (acute myeloid leukemia), cervix, Colon and rectal (colorectal), esophagus kidney and ureter, larynx, liver, oropharyngeal (including neck and part of the tongue, soft palate and tonsils), bronchial, lung. Smoking increases the risk of death in cancer patients and survivors of cancer and other diseases. If no one smoked, one of every three cancer…

respiration. There are two zones of the respiratory system, the conducting zone and the respiratory zone. The conducting zone is comprised of structured conduits for air to flow to sites of gas exchange and includes the nose, nasal cavity, pharynx, larynx, trachea, and bronchi. The respiratory zone is a site of gas exchange…

structures, mainly the alveoli, capillaries, and the respiratory membrane. I then drew pictures of the structures in different microscope powers. Summary: Very briefly, we will discuss how air travels to the lungs. First, air travels down your larynx, and then into the trachea, which splits into two bronchi. Air will go down the bronchi leading to the lung (one bronchi brings air to the lung while the other carries air out of the lung) and will travel to either the right or left lung via the…
