Wierd Noises from Your Body Called Phonology

➢ After leaving the pharynx, air enters the ;larynx, where two pairs of ligaments, together with the mucosa covering them, forms the vestibular and vocal folds. These folds help prevent foreign particles, including food, from entering the lower respiratory system.

Also known as the wind pipe. It is a long pipe formed of cartilage rings.

A phonological process is a typical pattern that all young children use when developing their speech. The child’s brain creates rules to simplify speech sounds and make words easier to say. As children grow older, they outgrow these patterns on their own and eventually, their speech becomes intelligible. A phonological process disorder is when a child continues to exhibit these patterns past the age expected for them to disappear. Phonological processes consist of syllable structure processes, substitution process, and assimilation processes.

The slide below shows a section of the trachea (windpipe).  Rings of hyaline cartilage embedded within the walls of the trachea provide support and help to maintain an open airway.  Hyaline cartilage is the most common form of cartilage in the body, making up part of the nose, connecting ribs to the sternum, and covering the articulating surfaces of bones. When sectioned and stained, the matrix of hyaline cartilage takes on a light purple color.  Cartilage-forming cells called chondroblasts produce this matrix, which  consists of an amorphous ground substance heavily invested with collagen fibers. Chondrocytes (mature cartilage cells) can be seen singly or in groups within spaces (called lacunae) in

The lungs is what provides the power source for voice production. The Larynx: The larynx, or the voice box is what produces the sound from vibration. The vocal folds make these vibrations.

The epiglottis is the most important of the cartilages of the larynx. The epiglottis is elastic cartilage because the epiglottis has to be flexible to be able to flap over the glottis during swallowing. The epiglottis is the most important because it literally stops food from entering your trachea when you swallow food. It allows the food to bypass your trachea, and go straight into your esophagus.

Cricothyroid approximation involves moving the cricoid cartilage backward and upward and thyroid cartilage forward and downward.

Like the nose it also filters dust and other particles from reaching the lungs, and it has mucous membranes to warm and moisten the air. When the air leaves the pharynx it moves on to the larynx. The larynx is also called the voice box. It not only remains open for speech, but also during respiration. The larynx merges with the trachea just below the vocal cords. The trachea is also called the wind pipe, and it is a one inch tube that connects to the bronchi. The bronchi divide into the right and left mainstream bronchi. After entering a lung each side branches off forming many smaller passages. In the center of the bronchi is the lumen. It is the central opening where the air passes through.

The air that we breathe in through the nose or mouth, travels through the larynx, down the windpipe, and then into the lungs. The larynx contains muscle called vocal cords. When we try to speak, the cords come together, and vibrate as we breathe out. This is what gives us our voice.

The thyroid gland is in the middle of the neck and lays over the trachea. It is a very vascular endocrine gland responsible for secreting hormones such as thyroxine (T4) and triiodothyronine (T3) (Jarvis, 2015). These hormones stimulate the rate of cellular metabolism (Jarvis, 2015). This gland has two lobes. Both lay posteriorly between the sternomastoid muscle and the trachea (Jarvis, 2015).

Then the air which is high in oxygen and low in carbon dioxide is sucked in through either the mouth or nasal cavity. It goes to the pharynx (throat) then passes through the larynx (voice box). It then pases through the trachea which is held open

Laryngeal cancer as its name suggests occurs in the tissue cells of the larynx. It is located between the base of the tongue and trachea and also contains the vocal cords. The larynx is composed of three parts, the supraglottis, glottis, and subglottis. In that order from upper, middle, and lower in relation to where it

Filters inspired air, produces sounds for vocalisation and contains the receptors for the sense of smell

The pharyngeal slits for filtering system food developed right into gills for drawing out oxygen, as well as later on right into today’s human top and also reduced mouth and also vocal cords, which incorporates the thyroid glandular, tongue, larynx (voice box) and also different glandulars as well as muscle mass in between the throat and also the mouth.

Common head and neck surgery includes the removal of the voice box: largyngectomy and tracheostomy: making an incision on the anterior aspect of the neck and opening an airway through an incision in the trachea. The removal of the larynx occurs in cases of laryngeal cancer and in this case the airway is separated from the mouth, nose and oesophagus meaning that the patient will breathe through a stoma in the neck. In tracheostomy cases the resulting stoma can act as an airway and a tracheotomy tube is inserted, enabling the individual to breathe without the use of their nose and mouth.
