Product Information

Carpus (knee): consists of 7-8 bones placed in 2 rows to form 3 joints. The 1st carpal bone is present only 50% of the time. Which on humans is the wrist. Bones of the lower limb, present in both the front and hind legs, include the cannon bone (3rd metacarpal/3rd metatarsal), splint bones (2nd and 4th metacarpal/metatarsal), proximal sesamoid bones, long pastern (proximal or 1st phalanx), short pastern (middle or 2nd phalanx), coffin bone (distal or 3rd phalanx), and navicular bone (distal sesamoid). There are usually slight differences in these bones when comparing the front and the hind. The 3rd metatarsal is about 1/6 longer than the 3rd metacarpal. Similarly, the 2nd and 4th metatarsals are longer in length when compared to their front-end counterpart. In the hindlimb, the 1st phalanx is shorter and the 2nd phalanx is longer than in the frontlimb. In addition, the 2nd and 3rd phalanx are narrower in the hind limb. The angle created by these three bones in the hindleg is steeper by about 5 degrees, therefore making the pastern angle steeper behind than in front.

You may ask me the basic difference between the horse and cow’s bones. Great, I love to answer you. The main differences between horse and cow bones are – Anthony, David W. (1996).

Horses exhibit a diverse array of coat colors and distinctive markings, described by a specialized vocabulary. Often, a horse is classified first by its coat color, before breed or sex. [42] Horses of the same color may be distinguished from one another by white markings, [43] which, along with various spotting patterns, are inherited separately from coat color. [44]

Edward Busuttil DVM, CertAVP, PgCertVPS, MRCVS, gives us an anatomical insight into how stability is maintained in this vital system See also: Horse sleep patterns and Sleep in non-humans When horses lie down to sleep, others in the herd remain standing, awake, or in a light doze, keeping watch. Ligaments attach bone to bone, and are vital in stabilizing joints as well as supporting structures. They are made up of fibrous material that is generally quite strong. Due to their relatively poor blood supply, ligament injuries generally take a long time to heal.

Their sense of smell, while much better than that of humans, is not quite as good as that of a dog. It is believed to play a key role in the social interactions of horses as well as detecting other key scents in the environment. Horses have two olfactory centers. The first system is in the nostrils and nasal cavity, which analyze a wide range of odors. The second, located under the nasal cavity, are the vomeronasal organs, also called Jacobson's organs. These have a separate nerve pathway to the brain and appear to primarily analyze pheromones.

Horse anatomy – a schematic representation of the 7 cervical vertebrae extending from the base of the skull to the first thoracic vertebrae, where the rib cage begins. Note the difference in shape of the atlas and axis compared with the rest of the vertebrae and rudimentary spinous processes present on the sixth and seventh vertebrae. Also note that the lamellar part of the nuchal ligament does not connect to the first and seventh vertebrae, allowing for more rotation in those regions.
