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.
Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.
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 ...
Pathophysiology. [] The sacroiliac joint is a true diarthrodial joint that joins the sacrum to the pelvis. [ 1 ][ 8 ][ 16 ][ 17 ] The sacrum connects on the right and left sides to the ilia (pelvic bones) to form the sacroiliac joints. The pelvic girdle is made up of two innominate bones (the iliac bones) and the sacrum.
The presacral fascia is limited postero-inferiorly, as it fuses with the mesorectal fascia, lying above the levator ani muscle, at the level of the anorectal junction. [2] These two fascias have been erroneously confused, [3] though they are in fact, separate anatomical entities. The colloquial term, among colo-rectal surgeons, for this inter ...
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".
The lumbosacral joint is a joint of the body, between the last lumbar vertebra and the first sacral segment of the vertebral column. [1] [2] In some ways, calling it a "joint" (singular) is a misnomer, since the lumbosacral junction includes a disc between the lower lumbar vertebral body and the uppermost sacral vertebral body, as well as two lumbosacral facet joints (right and left ...
