What is back anatomy?

back anatomy refers to the muscles of the back, as well as the bones of the shoulder blade, thoracic basket and spine. The rear part covering area from neck to tail are responsible for a wide range of functions, from the extension of the spine to the shrug. These muscles make it easier to move to one or more bone back, either to the spin processes of the vertebrae, ribs or blades. Many of them also connect to the back pan. Discussions about back anatomy can also mention the organs near the back, such as kidneys and lungs, but as the key structures found here concern the function of movement and weight, references to the back anatomy tend to focus on bones and muscles.

Because the spine is what determines the shape of the back, as well as the structure that leads to a large number of the rear part, it is perhaps the most important part of the back anatomy. The base of the skull into the pan consists of 33 stacked bones known as vertebrae. These include uterine vertebraein the throat, thoracic vertebrae chest basket in the upper and middle back, lumbar vertebra in the lower back and vertebra, which are part of the pelvis. The body of each vertebral is separated from the bodies above and below the bumper absorbing the intervertebral disc and each vertebra has several bony protrusions known as spinus processes protruding back and on both sides from the body. The muscles that move the spine attach to these processes.

Other bones included in the anatomy of the rear are 12 ribs and paired blades or shoulder blades. The ribs attach to 12 vertebral chest, each equipped with a rounded aspect on both sides of the vertebral body for articulation with individual ribs. While as the whole function for protecting the organs of the thoracic cavity and facilitating breathing by the effect of the muscle of the thoracic membrane, it also serves as a place of connection for many Ector Spinae muscles, which spread and side bending with the spine. Similarly, although the shoulder blades are considered part of the shoulder belt and are therefore narrowE associated with shoulder shoulder shoulders, many of these movements are initiated by back muscles, muscles that are attached directly to the blades such as trapezius and rotator cuff.

muscles corresponding to back anatomy are many, but can be classified and placed according to their function. Those who were mostly in the lower back, where they mainly operate or straightens the spine, are the muscles of the Erektor Spinae group: muscles iliocostalis, longissimus and spinalis. These muscles extend all the takes on the spine, where they can also contribute to movements such as rotation and lateral flexion in thoracic and cervical areas. Large muscles in the middle like Latissimus dorsi and the lower trapezoid tend to pull down on their arms and shoulder blades, while those found between shoulder blades such as rhombus and medium flattering, pull the blades back and move together. In the upper back, muscles work like upper trapezius and rotator cuff muscles mostly to lift or stabilize Raa small belt or arms, or to rotate the arms in the shoulder joint.
