The duct of the major sublingual glands lies between the genioglossal and mylohyoid muscles. It opens on a small sublingual caruncle that locates lateral to the rostral end of the frenulum. Salivary glands are the accessory organ of the dog digestive system anatomy. In a dog, you will find the same salivary glands – parotid, sublingual, mandibular, and zygomatic as found in the other animals. These are the major salivary glands of the dog’s oral cavity. So, again, you will find some of the minor salivary glands like buccal, palatine, lingual, and molar in the oral cavity of a dog.

Domestic dogs often display the remnants of countershading, a common natural camouflage pattern. The general theory of countershading is that an animal that is lit from above will appear lighter on its upper half and darker on its lower half where it will usually be in its own shade. [16] [17] This is a pattern that predators can learn to watch for. A counter shaded animal will have dark coloring on its upper surfaces and light coloring below. [16] This reduces the general visibility of the animal. One reminder of this pattern is that many breeds will have the occasional "blaze", stripe, or "star" of white fur on their chest or undersides. [17] Coccygeal vertebrae: the sacral vertebrae lead into these bones and it is into this area the tail bones are inserted. Due to differences in tail, this is the only part where the number of vertebrae will differ according to breed. However, there are generally between 20 and 23.

Peroneus longus: originates on both the tibia and fibula and inserts on the 4th tarsal bone and the plantar aspect of the metatarsals. It acts to flex the tarsus and rotate the paw medially. It is innervated by the peroneal nerve.

ISBN 9780231509435 In 1986, a study of skull morphology found that the domestic dog is morphologically distinct from all other canids except the wolf-like canids. The difference in size and proportion between some breeds are as great as those between any wild genera, but all dogs are clearly members of the same species. [5] In 2010, a study of dog skull shape compared to extant carnivorans proposed that "The greatest shape distances between dog breeds clearly surpass the maximum divergence between species in the Carnivora. Moreover, domestic dogs occupy a range of novel shapes outside the domain of wild carnivorans." [6]Most breeds have good vision, but some show a genetic predisposition for myopia – such as Rottweilers, with which one out of every two has been found to be myopic. [24] Dogs also have a greater divergence of the eye axis than humans, enabling them to rotate their pupils farther in any direction. The divergence of the eye axis of dogs ranges from 12–25° depending on the breed. [32] Tensor fasciae antebrachium: originates on the fascia covering the latissimus dorsi and inserts on the olecranon. It acts to extend the elbow. It is innervated by the radial nerve.

Again, I will share the list of male and female dog organs with a labeled diagram here. You will easily understand all the organs from both the male and female organs system as I provide the labeled diagrams. Let’s start with the pleura – it is the thin transparent serous membrane that encloses the lung and lines the interior of the thoracic cavity of a dog. Again, you may say pleura is a sac-like structure that comprises parietal and visceral portions. In most dogs, the central, intermediate, and corner incisor teeth erupt at the time between two to five months. The canine teeth of the dog erupt between four to five months.

Blood vessels – cephalic, saphenous, and external jugular veins are the most clinically important vessels in a dog. It is hard to show you all the blood vessels from the dog’s body in this article, but I will try to show some important vessels with their location. Again, this article might help you a little to understand the major vessels from the legs of a dog. Horowitz, Alexandra (2009). Inside of a Dog: What Dogs See, Smell, and Know.

Quadratus femoris: originates on the ischium and inserts on the intertrochanteric crest. It acts to extend the hip and rotate the pelvic limb laterally. Abductor pollicis longus: originates on the ulna and inserts on metacarpal 1. It acts to abduct the digit and extend the carpal joints. It is innervated by the radial nerve. The right and left lungs possess a base, an apex, costal surface, medial surface, cardiac impression, and cardiac notches. Each of these lungs has a concave diaphragmatic surface that lies against the convex surface of the diaphragm.

Common digital extensor: originates on the lateral epicondyle of the humerus and inserts on the distal phalanges. It acts to extend the carpus and joints of the digits 3, 4, and 5. It is innervated by the radial nerve. Here, you will learn the different structures and internal organs of a dog from the following systems –

Dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that stood only 6.3cm (2.5in) at the shoulder, 9.5cm (3.7in) in length along the head and body, and weighed only 113 grams (4.0oz). The largest known adult dog was an English Mastiff which weighed 155.6kg (343lb). [2] The tallest known adult dog is a Great Dane that stands 106.7cm (42.0in) at the shoulder. [3] As we explain above, canine anatomy is far ranging due to the diversity of existing breeds. These different breeds not only differ from each other in size, but in the shape of many body parts. Perhaps the most significant is head shape. There are three main different types of head formation in dogs: Extensor carpi radial: originates on the supracondylar crest and inserts on the metacarpals. It acts to extend the carpus. It is innervated by the radial nerve.
