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.
The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which it is partly blended), to the lower transverse sacral tubercles and the lateral margins of the lower sacrum and upper coccyx. Its oblique fibres descend laterally, converging to form a thick, narrow band ...
The intervertebral foramen (also neural foramen) (often abbreviated as IV foramen or IVF) is an opening between (the intervertebral notches of [1]) two pedicles (one above and one below) of adjacent vertebra in the articulated spine. [2]: 424, 425 Each intervertebral foramen gives passage to a spinal nerve and spinal blood vessels, and lodges a ...
Familial renal disease in animals. Familial renal disease is an uncommon cause of kidney failure in dogs and cats. Most causes are breed-related (familial) and some are inherited. Some are congenital (present at birth). Renal dysplasia is a type of familial kidney disease characterized by abnormal cellular differentiation of kidney tissue.
The perineal nerve is a branch of the pudendal nerve. [1] [2] It lies below the internal pudendal artery.It accompanies the perineal artery.It passes through the pudendal canal for around 2 or 3 cm. [1] [2] Whilst still in the canal, it divides into superficial branches and a deep branch. [1]
Sacral nerve stimulation. Sacral nerve stimulation, also termed sacral neuromodulation, is a type of medical electrical stimulation therapy. It typically involves the implantation of a programmable stimulator subcutaneously, which delivers low amplitude electrical stimulation via a lead to the sacral nerve, usually accessed via the S3 foramen.
Collecting lymphatic vessels. Anatomical terminology. [edit on Wikidata] The mammalian kidneys are a pair of excretory organs of the urinary system of mammals, [2] being functioning kidneys in postnatal-to-adult individuals [3] (i. e. metanephric kidneys). [2] The kidneys in mammals are usually bean-shaped [4] or externally lobulated. [5]
Dog anatomy. Dog anatomy comprises the anatomical study of the visible parts of the body of a domestic dog. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, [ 1 ] as dogs are highly variable in height and weight.
