Anatomy of the Horse

Introduction

The anatomy of the horse is the description of the internal parts of the animal. It was studied earlier by the man as the latter sought to understand how it works to better use. One of the first books on the horse's anatomy is that of Carlo Ruini, in 1598. The Equus caballus has 64 chromosomes (inherited material in the cell nuclei). Their close relatives such as zebras, Przewalski's horse and wild ass have different chromosome numbers, although the resemblance in structure stands belonging to the Equidae family. Like other species of mammals, the horse has four basic tissue types, known as:

Epithelial tissue

It corresponds to the skin and internal ducts and hollow organs; like intestine, biliary tract, bladder, and uterus. The glands that produce hormones and other substances are formed by this tissue.

Nerve Tissue

Transmits messages over long distances and form the brain, spinal cord and nerve pathways which largely control bodily functions.

Tissue

Bone structure supports and gives shape to the body and soft structures. Blood is a very special form of this type of tissue. In its simplest form are tendons, ligaments, and sheaths of fibrous material surrounding or protecting various organs and muscles (Goody 2000, 90).

Quarter Horse

It consists of a substance similar to nail the man, which protects it from wear up to a quarter of the weight of the animal. Is an inert substance composed largely of keratin secreted by the coronary corium, growth ranges from 0.5 cm. monthly, is nurtured by sensitive films, which are leaf-shaped structures that line the roll and connecting the town to the bone intertwined with leaves like blades located in Hull insensitive. It is formed on the outside of a substance in the cornea which are navicular bone and roll, digital cushion, lateral cartilages, articulation coronopedal, nerves and blood vessels. The inner layer is formed with the lid, palm, locks and frog, due to continued growth, replaces lost due to surface wear and tear.

Skeleton

Its skeleton consists of 210 individual bones, providing support to the muscles, while protecting the internal organs; their components have the mobility needed for the animal to move. Its various joints provide different degrees of mobility. The bones of the joints are covered with cartilage, which is softer than bone and replaces the effects of wear on the surface. The joint is completed by the capsule that produces synovial fluid, which is a joint fluid that lubricates the joint surfaces, reinforcing the ligaments connecting the bones.

The skeleton is formed so that satisfies particular functions. The surface of the scapula and the transverse processes of lumbar vertebrae have a large space in the insertion of powerful muscles that facilitate movement of the front and rear legs. The skull is relatively elongated, leaving room for the teeth and their roots, the orbits of the eyes are distant, peripheral vision giving the alert for danger. The skeleton has several features, among the most important ones are small and metarsianos metacarpals, which are located ...
