The trachea is no more than 4 mm in diameter during the first year of life, expanding to its adult diameter of approximately 2 cm by late childhood. [2] [3] The trachea is more circular and more vertical in children compared to adults, [3] varies more in size, and also varies more in its position in relation to its surrounding structures. [2]
A soft palate is considered elongated when it extends past the top of the epiglottis and/or past the middle of the tonsillar crypts. [1] The soft palate is made up of muscle and connective tissue located in the posterior portion on the roof of the mouth. The soft palate creates a barrier between the mouth (oral cavity) and nose (nasal cavity). [2]
It carries air from the mouth and nose all the way to the lungs. It is made up of rings of cartilage that form a tube-like structure. The cartilage helps to hold the trachea open and prevent it ...
Cats are carnivores that have highly specialized teeth. There are four types of permanent teeth that structure the mouth: twelve incisors, four canines, ten premolars and four molars. [1] The premolar and first molar are located on each side of the mouth that together are called the carnassial pair.
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
Reverse sneezing, also known as inspiratory paroxysmal respiration, is a clinical event that occurs in dogs and cats. It is possibly caused by a muscle spasm at the back of the animal's mouth, more specifically where the muscle and throat meet. [1] Other hypotheses state that it occurs when the animal's soft palate gets irritated. The ...
Tracheal collapse in dogs is a condition characterized by incomplete formation or weakening of the cartilaginous rings of the trachea resulting in flattening of the trachea. It can be congenital or acquired, and extrathoracic or intrathoracic (inside or outside the thoracic cavity). Tracheal collapse is a dynamic condition.
Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
