Fractures near the symphysis, and of the rami, either of the os pubis or ischium, are usually attended with injury to the bladder or to the urethra.
In the mid-line a slight furrow extends from the ensiform cartilage above to the symphysis pubis below; this marks the linea alba in the abdominal wall, and about its middle point is the umbilicus or navel.
They have sometimes been interpreted as a hinder part of the sternum, but may more probably be regarded as a pair of prepubic bones articulating each with the anterior process of the pubis (see Fig.
Some follow the Amphibian nomenclature, and unite the ischium and pubis into one bone, which is then termed ischium, when the prepubis is termed the pubis, and regarded as removed from the acetabulum.
The notch between the ischium andpubis is well marked in Pterodactylus longirostris, and better marked in Pterodactylus dubius, Cycnorhamphus Fraasii, and Rhamphorhynchus.
First, the type of Rhamphorhynchus, in which the pubis and ischium are inclined somewhat backward, and in which the two prepubic bones are triangular, and are often united together to form a transverse bow in front of the pubic region.
There is some difference in the pubis and ischium which is more conspicuous in form than in direction of the bones.
Secondly, there is the ordinary form of pelvis in which the pubis and ischium usually unite with each other down their length, as in Dimorphodon, but sometimes, as in Pterodactylus dubius, divide immediately below the acetabulum.
In the pelvis referred to the Theriodont Deuterosaurus there is some approximation to the pelvis of Rhamphorhynchus and of Pterodactylus dubius in the depth of the division between the pubis and ischium.
They are unknown in any other existing animals, unless present in Crocodiles, in which ischium and pubis are always undivided.
In such a Dinosaur as the American carnivorous Ceratosaurus the two bars of the pubis and ischium remain separate and diverging, and there is no film of bone extending over the interspace between them.
On the surface of the abdomen the position of this vessel would be indicated by a line drawn from about an inch on either side of the umbilicus to the middle of the space between the symphysis pubis and the crest of the ilium.
It may lie above thepubis in the anterior wall of the bladder.
The angle of union of the ossa pubis in the male is from sixty to eighty degrees, whereas, in the female it is ninety degrees.
The ligamentous cartilage at the symphysis pubis is broader and shorter.
Owing to smaller stature, and to greater size of the abdominal region, the middle point, which is at the pubis in the male, is situated higher in the female.
If, in consequence of the form of the pelvis, and the arch of the pubis being larger, the mons veneris be not more prominent than the chest; because, the pelvic cavity is then also insufficient for gestation and parturition.
The pelvis approximates to that of the Apterygidae, but the pectineal process of the pubis is less developed, and the ischium and pubis may be longer and more slender.
The pubis has a small pectineal process; and the ventral aspect of the true and postacetabular vertebrae is very broad and much flattened.
While the bladder is fully expanded, 4, there occurs an interval between the margin of the symphysis pubis and the point of reflexion of the peritonaeum, from the recti muscles, to the summit of the viscus.
The inner fossa is bounded by the epigastric artery externally; by the margin of the rectus muscle internally; and by the os pubis and inner end of Poupart's ligament inferiorly.
Pediculosis pubis is a condition due to the presence of the pediculus pubis, or crab-louse.
A cartilage or bone in front of the pubis in some amphibians and other animals.
He is not normally covered all over with hair, but there is hardly a spot on his body where hairs may not sprout, and both sexes are hairy often with extreme abundance in pubis and arm-pits.
The pubis consists of a short anterior portion (spina pubica or pectineal process, homologous with the prepubic process of Dinosaurs) and the long and slender pubis proper (equivalent to the processus lateralis pubis of most reptiles).
The pectineal process is variable; it may grow entirely from the pubis, or both pubis and ilium partake of its formation, or lastly its pubic portion may be lost and the process is entirely formed by the ilium.
In the order Ornithischia the pubis extends backward along the ischium as it does in the birds.
The pubisforms the front third and the ischium the rear third of this socket.
The paired ilium is joined to each side of the backbone and projects downward to meet the pubis and ischium at the socket for the head of the thigh bone.
The distance from the xiphoid to the symphysis pubis was three feet.
Eldridge gives an instance of separation of the symphysis pubis during labor,--a natural symphysiotomy.
The circumference of the abdomen was six feet four inches, and the distance from the xiphoid to the os pubis measured four feet 1/2 inch.
He married in 1870, and upon being told that he was a father he slit up the hypogastrium from the symphysis pubis to the umbilicus, so that the omentum protruded; he said his object was to obtain a view of the interior.
It was connected to the pubisby a short stem 1/2 inch long and as large as the little finger, consisting of separate bones and cartilages.
The Ephemerides speaks of a case of coalition of the bladder with the os pubis and another case of coalition with the omentum.
Whence it would appear, that their breasts possess an intermediate sympathy between the pubis and the throat; as they are the seat of a passion, which men do not possess, that of suckling children.
This happens probably from there being in them a more exquisite sensitive sympathy between the pubis and the breasts.
Y-- the ilium above, the ischium and pubis below, and the acetabulum at the junction of the three.
Hence in the course of growth the pelvis not only becomes proportionally higher, but it undergoes a rotary movement around the cotyloid axis; this movement has the effect of elevating the pubis and bringing the ischium forward.
The pubis has a strongly developed pectineal process, which occasionally unites with a process from the ilium enclosing a large pre-acetabular foramen.
The remainder of the pubis is homologous with the post-pubis of Orthopod Dinosaurs.
The pubis is fused with the ischium, and both pectoral and pelvic girdles are remarkably solid.
The =ischium=, the smallest bone of the three, is flattened and like the pubismeets its fellow in a median symphysis.
In Chelonia and Lacertilia the pubis bears a lateral process which is homologous with the post-pubis of Iguanodon.
There is a large pre-pubis directed downwards and forwards, meeting its fellow in a ventral symphysis, but there is no post-pubis.
The pubis is united to both ilium and ischium, the acetabulum has a large unossified space, and neither pre-pubes nor post-pubes meet in ventral symphyses.
In the pelvis the pubis remains cartilaginous, and there is a bifid cartilaginous epipubis.
In Iguanodon the pubisconsists of two portions, viz.
Concerning the reptilian pubis there are considerable difficulties.
In these animals the pubis does not take part in the formation of the acetabulum, and the ischium bears on its outer side a well-marked ischial tuberosity.
The reptilian pubis is best understood by comparing the arrangements met with in the various other groups with that in the Orthopod Dinosaurs such as Iguanodon.
It is probably homologous with the pre-pubis of Dinosaurs but in some birds is formed in part by the ilium.
But two or three inches above the symphysispubis the section opened a collection of pus which extended downward into the pelvis.
The promontory and sacrum are pushed in, the arcus pubis is large, the pelvis asymmetric; the small pelvis is contracted, the large pelvis broader.
This part is called the conjugata vera, and it is the diameter from the promontory of the sacrum behind to a point on the inner surface of the symphysis pubis in front.
Symphyseotomy is an operation in which the joint of the pelvis at the symphysis pubis is cut, and the pelvis is allowed to gape so as to let out the child.
In the pelvic girdle the ilium corresponds to the scapula, the ischium to the coracoid, the pubis to the clavicle.
Hence the ilium is a pleurapophysis, the ischium and pubis are both hæmapophyses.
In her eighth labour the pelvis then appeared to be somewhat less than 2-1/2 inches from the symphysis of the ossa pubis to the superior and projecting part of the os sacrum, and otherwise badly formed.
In the fifth month, the fundus will be felt half way, or a little more, between the symphysis pubis and umbilicus.
It is here that the position of the head upon the symphysis pubis will prove a valuable means of diagnosis.
That portion of the uterus which extends between the symphysis pubis and os uteri is now not only more convex but lower in the pelvis than the os uteri itself.
We occasionally meet with cases of retroversion where the os uteri, although carried more or less upwards and forwards, is not forced, to that extreme height behind the symphysis pubis as is usually observed.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "pubis" in a variety of sentences. We hope that you will now be able to make sentences using this word.
