1Excessive inward curvature of the spine.Compare with kyphosis
- ‘A side view of a normal spinal column demonstrates reciprocal curves, beginning with cervical lordosis and then lumbar lordosis.’
- ‘Patients develop thoracic kyphosis and lumbar lordosis as vertebral height is lost.’
- ‘The anatomical position of her spine could not be viewed optimally because of the pronounced lordosis, and this could prolong the procedure.’
- ‘The Thomas test will help to identify the presence of a hip flexion contracture by eliminating the effects of excessive lumbar lordosis on the perceived extension of the hip.’
- ‘Participants who find their backs are excessively arched may find it easier to place their feet on the edge of the bench, which will help to reduce their lordosis.’
- 1.1 A posture assumed by some female mammals during mating, in which the back is arched downward.
- ‘Other postcopulatory calls function in prolonging lordosis of the mated female, attracting other females or deterring males.’
- ‘These hormonal effects have been demonstrated most clearly for reproductive behaviors, such as the mounting of female animals by males and the receptive lordosis posture adopted by females in response to these mounts.’
- ‘The expression of the lordosis posture is under tonic inhibition by brain nuclei whose activity is suppressed by steroid hormones from the preovulatory follicles.’
- ‘The limitation is, particularly in female mice, is all you can study is lordosis, or the posturing of the female mouse receptive to male sexual function.’
Early 18th century: modern Latin, from Greek lordōsis, from lordos ‘bent backwards’.
