Dog anatomy. Dog anatomy comprises the anatomical study of the visible parts of the body of a domestic dog. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, [ 1] as dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that ...
In mammalian oral anatomy, the canine teeth, also called cuspids, dogteeth, eye teeth, vampire teeth, or fangs, are the relatively long, pointed teeth. In the context of the upper jaw, they are also known as fangs. They can appear more flattened, however, causing them to resemble incisors and leading them to be called incisiform.
Transverse section of the trachea, just above its bifurcation, with a bird’s-eye view of the interior. (Carina not labeled; the ridge that separates the left and right bronchus.) The carina of trachea (also: " tracheal carina " [ 1]) is a ridge [ 1] of cartilage [ 2] at the base of the trachea separating the openings of the left and right ...
Retina of a mongrel dog with strong tapetal reflex. The tapetum lucidum ( Latin for 'bright tapestry, coverlet'; / təˈpiːtəm ˈluːsɪdəm / tə-PEE-təm LOO-sih-dəm; pl.: tapeta lucida) [ 1] is a layer of tissue in the eye of many vertebrates and some other animals. Lying immediately behind the retina, it is a retroreflector.
Human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting. As such, they are considered part of the human digestive system. [ 1] Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function.
The spot to the left of the centre is the macula. The grey, more diffuse spot in the centre is a shadow artifact. The fundus of the eye is the interior surface of the eye opposite the lens and includes the retina, optic disc, macula, fovea, and posterior pole. [ 1] The fundus can be examined by ophthalmoscopy [ 1] and/or fundus photography .
The canine space (also termed the infra-orbital space ), [1] is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a thin potential space on the face, and is paired on either side. It is located between the levator anguli oris muscle inferiorly and the levator labii superioris muscle superiorly.
The iris ( pl.: irides or irises) is a thin, annular structure in the eye in most mammals and birds, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm.
