Explanation of the noun of the pelvic diaphragm, explanation of the noun of the pelvis

The explanation of pelvic noun is the bony structure of the human body.

The pelvis is a bony structure of the human body, mainly composed of hip bones, sacrum, and coccyx, and the main ligaments are sacrotuberous ligaments, iliopsobar ligaments, and sacrospinous ligaments.

In men, the upper mouth of the pelvis is heart-shaped, the lower mouth is narrow, and the pelvic cavity is narrow, mostly funnel-shaped; In women, the upper mouth is round, the lower mouth is wide, and the pelvic cavity is short and wide, mostly barrel-shaped.

The pelvis is further divided into a large pelvis and a small pelvis, also known as a false pelvis and a true pelvis. The large pelvis is not directly related to sexual function or birth canal. The small pelvis houses many organs, including the bladder, urethra, rectum, ovaries, uterus, ureters, fallopian tubes, and other organs.

The female pelvis is the birth canal where the fetus is delivered, and the size of the pelvis also directly affects the difficulty of fetal delivery.

The pelvis, the pelvic skeleton that connects the spine to the lower limbs, is a complete bony ring that connects the sacrum, coccyx (the two lowest bones of the spine) and the left and right hip bones.

Basic Information. The pelvis connects the pelvic-like skeleton between the spine and the lower limbs. A complete bony ring made up of the posterior sacrum, the coccyx (the two lowest bones of the spine), and the left and right hip bones.

The pelvis both transmits body weight to the two lower limbs and serves as the basis for movement of the free lower limbs, as well as supporting the protection of intrapelvic organs.

Anatomy. The sacrum, iliac and sacrum and coccyx are supported by strong ligaments to form joints, which are generally immobile, and after pregnancy under the influence of hormones, the ligaments are slightly relaxed, and the joints are slightly loosened, which is beneficial to childbirth.

The entire pelvic boundary is divided into a large pelvis in the upper part (false pelvis) and a small pelvis in the lower part (true pelvis). The boundary line is a circular line enclosed by the sacral promontory, the anterior edge of the sacral wings on both sides, the arcuate lines on both sides, the pubic comb, the pubic tuberosity, the pubic clear crest and the upper edge of the pubic symphysis, that is, the upper mouth of the small pelvis, through which the large and small pelvis are connected.

The lower pelvic orifice is uneven and consists of the tip of the coccyx and the sacrotuberous ligaments on both sides, the ischial tuberosity, the pubic arch, and the lower border of the pubic symphysis, which is diamond-shaped. The part between the upper and lower mouths is the pelvic cavity.

In males, the anterior superior iliac spine and pubic symphysis of the pelvis are located within the same coronal plane; In women, the anterior superior iliac spine is more anteriorly tilted about 1 cm. There is a significant gender difference in the pelvis, because the female pelvis is closely related to the conception and delivery of the fetus.

The pelvis, also known as the girdle and hip, is a skeletal structure located at the end of the spine that connects the spine and femur, and connects with the hind limbs of quadrupeds and the lower limbs of bipeds. The femur and the waistband form the hip joint where the hip joins.

It is a ball-and-socket joint.

by the left and right hip bones.

It is formed with the sacrum, coccyx, and the bony connections between them.

Boundary: by the sacrum.

A circular line formed by the promontory, arcuate line, pubic comb, pubic tuberosity, and the upper edge of the pubic symphysis.

The pelvis is formed by the sacrum, coccyx, and two hip bones and their ligaments.

pelvic diaphragm

diaphragma pelvis

pelvic diaphragm

The pelvic diaphragm consists of the anterior levator ani muscle and the posterior coccygeus muscle, as well as the upper and inferior fascia of the pelvic diaphragm covering both muscles and below, and is also known as the pelvic floor (Fig. 92). The pelvic diaphragm has the functions of supporting pelvic organs, assisting in defecation, childbirth and so on.

Fig.92 Pelvic diaphragm (view, above).

a) levator ani is a latissimus muscle, and the two sides are joined to form a funnel-shaped. It arises from the pelvic surface of the pubic symphysis, the pelvic fascial tendon arch (levator ani tendon arch), and the pelvic surface of the ischial spine. The muscle fibers are posterior medial and meet the contralateral muscle fibers at the midline and terminate at the central perineal tendon, anococcygeal ligament, and the tip of the coccyx.

In front of the central perineal tendon, the muscle fibers of the anterior part of both sides form a pelvic diaphragmatic hiatus, which passes through the urethra in males and the urethra in females.

According to the start and end and arrangement of muscle fibers, the levator ani muscle can be divided into four parts: pubic ** muscle (female) or levator prostate muscle (male), puborectalis muscle, pubococcygeal muscle, and iliococaudalis muscle from front to back.

The pubic muscle pubovaginalis in women and the levator prostatae in men both originate from the pubic symphysis and the anterior part of the levator ani tendon arch, and the muscle fibers of the pubic muscle walk along both sides of the urethra and intertwine with the muscle fibers of the urethra, which has the effect of helping to narrow the mouth. The muscle fibers of the levator prostate muscle terminate at the central perineal tendon through both sides of the prostate and have the effect of supporting the prostate.

The puborectalis puborectalis arises from the pubic pelvic surface and anterior part of the levator ani tendon arch, and the muscle fibers run posteriorly and medially and intertwine with the contralateral fibers to form a U-shaped loop, which surrounds the lateral and posterior sides of the junction of the rectum and anal canal to assist in the sphincter**

The pubococcygeus pubococcygeus arises in the middle of the levator ani tendon arch and terminates in the anoccygeal ligament.

The iliococcygeus muscle begins in the posterior part of the levator ani tendon arch and ischial spinous pelvic face, and ends in the anoccygeal ligament and the lateral border of the coccyx.

The pelvis is made up of the left and right hip bones, the sacrum and coccyx, and the bony connections between them. Boundary: A circular line composed of the sacral promontory, arcuate line, pubic comb, pubic tuberosity, and superior edge of the pubic symphysis.
