Anatomical terms of bone. [ edit on Wikidata] The sacrum (pl.: sacra or sacrums[ 1 ]), in human anatomy, is a large, triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1–S5) between ages 18 and 30. [ 2 ] The sacrum situates at the upper, back part of the pelvic cavity, between the two wings of the pelvis.
In human anatomy, the sacral plexus is a nerve plexus which provides motor and sensory nerves for the posterior thigh, most of the lower leg and foot, and part of the pelvis. It is part of the lumbosacral plexus and emerges from the lumbar vertebrae and sacral vertebrae (L4-S4). [1] A sacral plexopathy is a disorder affecting the nerves of the ...
The sacrococcygeal symphysis (sacrococcygeal articulation, articulation of the sacrum and coccyx) is an amphiarthrodial joint, formed between the oval surface at the apex of the sacrum, and the base of the coccyx. It is a slightly moveable joint [1] which is frequently, partially or completely, obliterated in old age, [2] homologous with the ...
Sacrovertebral angle. Lumbar vertebrae are yellow, and sacrum is green. Anatomical terminology. [ edit on Wikidata] The sacrum is curved upon itself and placed very obliquely, its base projecting forward and forming the prominent sacrovertebral angle when articulated with the last lumbar vertebra . It is also known as the "lumbosacral angle".
Sacral fracture. A sacral fracture is a break in the sacrum bone. The sacrum is the large triangular bone that forms the last part of the vertebral column from the fusion of the five sacral vertebrae. Sacral fractures are relatively uncommon. They tend to be caused by high-energy trauma, for example in road traffic accidents or in falls.
Caudal regression syndrome. Caudal regression syndrome, or sacral agenesis (or hypoplasia of the sacrum), is a rare birth defect. It is a congenital disorder in which the fetal development of the lower spine —the caudal partition of the spine—is abnormal. [1] It occurs at a rate of approximately one per 60,000 live births.
6425. Anatomical terminology. [ edit on Wikidata] The sacral spinal nerve 3 (S3) is a spinal nerve of the sacral segment. [ 1 ] It originates from the spinal column from below the 3rd body of the sacrum. Sacrum, showing bodies in center.
