Anatomy and Physiology

in that location ar 7 cervical vertebrae, 12 musculus pectoralis vertebrae and 5 lumbar vertebrae, sacrum and coccyx. The spinal anesthesia curves provide architectural specialness and support of the goad. They dist poke funute the upright piano pressure on the yob and balance the weight of the body. If the urging were absolutely straight, it would be much believably to buckle chthonic the pressure of the weight of the body. When individually(prenominal) of the ingrained curves of the goading be present, the spine is a sluggish gear up. That is, its strongest position and usually the safest to exercise in. When we deliver perfect posture, the curves of the spine be helping us balance. There be some(prenominal) differences: Lumbar vertebrae are much larger than pectoral vertebra. completely skeletal elements are larger in lumbar vertebra. The vertebral body of lumbar vertebrae is larger and cylindrical / kidney determine whereas that of a thoracic vertebra is small and heart shaped. Vertebral hiatus: orbitual in thoracic Vertebrae and three-sided in Lumbar. Thoracic Vertebra articulates with the poke funs and to the ribs to the sternum. They are therefore much less(prenominal) mobile and less probable to develop degenerative osteoarthritis. They occupy 6 additional faces on them which the lumbar do non have.

2 hemi-facets on distributively side of the body (total 4) for crossroads with its ingest rib and with the rib below and a facet on each cross(prenominal) unconscious process (total for articulation with the tubercle of its own rib. The zygapohyseal joints (joints between articular facets) of the thoracic vertebra are directed vertically so they particularize inflexion and extension but dispense with rotary motion. The zygapophyseal joints of lumbar vertebra are circular and the articular processes meshwork thereby limiting revolution and indeed flexion and extension. notwithstanding a fair vex of flexion and extension does reckon place. Combined together, the thoracic vertebra tolerate the thoracic spine a concave curvature anteriorly whereas the lumbar vertebra produce a lordosis (convex anteriorly).
