vertebrae column

THE VERTEBRAE COLUMN
or spinal column, is a long series of bones that of the base of the skull down to the pelvis. He is tough and flexible at the same time, supports the head and body, keep the torso upright and sets back unable to move. It consists of 33 vertebrae that contain the spinal cord.

CERVICAL VERTEBRAE
The seven cervical vertebrae (C1 / m C7) forms the neck and head support.

THORACIC VERTEBRAE
The twelve thoracic vertebrae (T1 t / m T12) are located on both sides attached to the twelve ribs, which, together with the sternum form the chest.

LUMBAR VERTEBRAE
The five lumbar vertebrae (L1 t / m L5) are located on the underside of the back and are the largest. This part of the spine captures most of the press.

SACRAL
The sacrum is a triangular bone with five fused vertebrae exists.

COCCYX
The coccyx is a small bone that attaches to the sacrum. It consists of smaller and fused vertebrae (usually four). It is a remnant of the tail of mammals.

THE INTERVERTEBRAL DISCS
The top and bottom sides of each vertebra to be separated by intervertebral discs, which are made of cartilage. Their function is to absorb or cushion the shock and the pressure associated with movements and efforts. The thickness of the discs is variable, between the lumbar vertebrae, they are the thickest.

THE LIGAMENTS
The vertebrae are interconnected by the fibrous bands, ligaments, rear and between the vertebrae, which over the entire length of the spine.

DID YOU KNOW:

Man Gay sapiens or a bipedal primate species in the family Hominidae. Research suggests that modern humans about 200,000 years ago in Africa emerged as a species. Humans have highly developed brains, which he is capable of abstract thinking, language, introspection, problem solving and emotion. Thanks to his intelligence and upright posture, allowing the arms to be free to pick up objects and manipulate, the man much more than other species able to use tools.
