Lordosis is historically defined as an abnormal inward curvature of the lumbar spine. [1] [2] However, the terms lordosis and lordotic are also used to refer to the normal inward curvature of the lumbar and cervical regions of the human spine. [3] [4] Similarly, kyphosis historically refers to abnormal convex curvature of the spine.
Swayback, also known clinically as lordosis, [1] refers to abnormally bent postures in the backs of humans and of quadrupeds, especially horses. Extreme lordosis can cause physical damage to the spinal cord and associated ligaments and tendons [1] which can lead to severe pain.

As a result, in humans the muscles of the forehead (the occipitofrontalis) are only used for facial expressions. [10] Increasing brain size has also been significant in human evolution. It began to increase approximately 2.4 million years ago, but modern levels of brain size were not attained until after 500,000 years ago.
Kyphosis (from Greek κυφός (kyphos) ' hump ') is an abnormally excessive convex curvature of the spine as it occurs in the thoracic and sacral regions. [1] [2] Abnormal inward concave lordotic curving of the cervical and lumbar regions of the spine is called lordosis.
The cell bodies of Betz cell neurons are the largest in the brain, approaching nearly 0.1 mm in diameter. The axons of the upper motor neurons project out of the precentral gyrus travelling through to the brainstem, where they will decussate (intersect) within the lower medulla oblongata to form the lateral corticospinal tract on each side of ...
