Larynx

1) What is the vocal tract and where, exactly, is it located? The vocal tract is the area through which air passes to create sound. It goes as far down as your larynx, up to the tip of your nose and the end of your lips. 2) Regarding inhalation, what might be some reasons that the author cautions not to “really yawn”? What does your own voice sound like when you sing or speak through the openness created by a completely full yawn? If you “really yawn” you are relaxing your muscles too much in…

1. Definition of Asthma: Asthma is one of the most common type of chronic obstructive pulmonary disease (COPD). A COPD is a type of disease or disorder to which the airway is affected and causes breathing to be slowed or forced. Asthma is a type of COPD that causes the airway to become inflamed and to be hypertensive (increased pressures in the blood vessels in the airway) due to any internal or external stimuli. The system that is closely associated with asthma is the respiratory system. The…

and help us stay alive. The nasal cavity is a large air space which is filled above the nose. Each nasal cavity is a part of one of the two nostrils. The trachea is a tube and air-breathing vertebrates from the larynx to the bronchi, acting as the passage conveying air to the lungs. The Larynx is a hollow muscular organ making an air passage to the lungs holding the vocal cords in humans. The bronchi is a large air passage, they get smaller the closer they are or get to the lung tissue. These…

It is covered with a mucous membrane and taste buds located at the larynx. It is shaped like a leaf and guards the entrance of the glottis. It is one of the nine cartilage structures. You can see The upper surface of the epiglottis. When you swallow food it folds over the glottis to stop liquid and food from entering the trachea so the food goes into the oesophagus. It also is used for speech sounds in some languages. The larynx is also known as the voice box. The trachea or wind pipe has…

Diphtheria Diagnosis & Treatment: The doctor will conduct a physical examination and check your mouth for grey or a black coating, which is a classic symptom of Diphtheria. He will also look for enlarged lymph glands and swelling of the neck and the larynx. Common lab tests for confirming the disgnosis include: - Gram stain or throat culture to identify the bacteria - Toxin assay to detect the presence of toxins - Electrocardiogram If Diphtheria is confirmed, or even suspected, the doctor…

It’s been proven many times that human and non-human primates are closely related to each other. We have similar number of species, similar DNA, similar brain size, similar sociability, and some similar characteristics. Well, how about speaking capabilities? Can they speak like us? Many people may say no, but researchers have a different answer in mind. A well-known and long-kept theory says that chimps, monkeys, and gorillas do not talk because they are incapable of creating sounds for the…

The systematic study of speech and the sounds of language is referred to as phonetics. Traditionally phoneticians rely on careful listening and observation in order to describe speech sounds (Nolan, 2007). Phonetics is often defined with respect to phonology. Both disciplines are concerned with the sound medium of language. Phonology is concerned with the pattering of sounds in a language (and in language in general), and is thus comparable to areas of linguistics such as syntax and morphology…

whales, dolphins, seals, otters, beaver, muskrat, hippopotamus and walrus. These diving mammals don't breathe underwater as fish do, so their respiratory systems had to protect the body from the surrounding water; valvular nostrils and an intranarial larynx exclude water while breathing and swallowing. To navigate and detect prey in murky and turbid waters, aquatic mammals have developed a variety of sensory organs: for example, pinnipeds have elongated and highly sensitive whiskers that can…

Pribuisiene, R., Uloza, V., Kupcinskas, L., & Jonaitis, L. (2006). Perceptual and Acoustic Characteristics of Voice Changes in Reflux Laryngitis Patients. Journal of Voice, 20(1), 128-136. In 2006, Pribuisiene, Uloza, Kupicinskas, and Jonaitis examined vocal differences in individuals with reflux laryngitis using perceptual, subjective, and instrumental measures. There were 108 participants with reflux laryngitis and 90 individuals in the control group. Acoustic analysis of reflux laryngitis…

The male reproductive system , as stated previously, is different from the female reproductive system. The male reproductive system consists of testes, ducts, accessory sex glands, the penis, and scrotum (McLafferty, 2012 p1). The testes consist of glandular tissue and each testis is contained in a white fibrous capsule called the tunica albuginea (McLafferty 2012 p1). The testes are held in the scrotum which is a loose sac of skin and smooth muscle. Approximately two months before birth, the…
