|TABLE 23.3 Chronology and Histogenesis of the Interpubic Joints in Female |
Micea Age (Weeks After Birth) One Histology Ventral portion of the pelvis is made
of a solid, inflexible bar of small-celled hyaline cartilage and connects the pubic ...
|It should be recognized that some biological effects of relaxin occur in certain |
species, but not in others. interpubic ligament can enable marked increases in
the size of the birth canal. Transformation of the pubic joint cartilage to a flexible
|Here, I shall concentrate primarily on those vertebrates in which the interpubic |
joint is a synchondrosis, i.e., group (b). Within this group, several types of
interpubic joint may be distinguished on the basis of the histological changes
observed to ...
|The analyses of cellular death in the mouse interpubic tissue demonstrate a peak |
at the end of pregnancy. The phenomenon of cellular death continues in the
interpu- bic tissue until 5days postpartum when the symphysis already presents
|Mouse The pubic symphysis of the male mouse remains cartilaginous, while in |
the female the cartilage is replaced by an interpubic ligament at sexual maturity (
Gardner, 1936). During the first pregnancy the pubic bones are resorbed at their
|The inter-pubic ligament is composed of fibrous fasciculi, which pass obliquely |
downwards from one os pubis to the other, decussating each other in their course
: they become less oblique towards the superior and inferior parts of the ...
|The Reptile pelves present some specimens which approach the Mammalian |
type, in the formation of a perfect pelvic girdle by inter- pubic and inter-ischial
symphysis. In these animals, however, the three components of the innominate
|Interpubic ligaments. Interpubic ligament lengths are shown in Table I. In |
conformity with previous studies (4-7, 9, 14) ECP increased the interpubic gap in
ovariectomized mice and synergized R in inducing formation of long interpubic ...
|Zarrow: I think that I can best illustrate the species specificity by discussing the |
action of relaxin on the elongation of the interpubic ligament. A number of years
ago, we pointed out that different species evolved different methods for the
