The iliopubic eminence possesses a margin known as the iliopectineal line. Iliopectineal line is created by combination of arcuate line from the ilium and pectineal line from the pubis. Inferiorly, the Iliopectineal line is divides the pelvis superiorly into the pelvis major or false pelvis and the pelvis minor or true pelvis. It creates the [...]
Lymph from pelvic organs returns via the lymphatic vessels and nodes of the pelvis. The size, location and number of various groups and sub-groups of lymph nodes in the pelvic region are different in different individuals. Functions They are accountable for the elimination of interstitial fluid from tissues. They carry white blood cells towards and [...]
The external surface of the ischiopubic ramus anterior gives connection towards muscles of the medial section of the thigh, towards the ischial tuberosity along with the body of the pubis. Adductor longus, adductor brevis, adductor magnus, pectineus, and gracilis are among those muscles. Ischiopubic Ramus Attachments and Surfaces The ischiopubic ramus possesses external [...]
The birth passage is made up of three parts, the pelvic inlet, pelvic cavity, and the pelvic outlet. The bony pelvis can be classified into four types: Gynecoid Android Anthropoid Platypelloid Types of Bony Pelvis Among them, the gynecoid type of pelvis is the most commonly found and has the diameters [...]
There are four bony projections in the ilium, which is a bone of the pelvic girdle, with each one functioning as points of attachment for muscles and ligaments; the term iliac spine refers to any four projections of the ilium. The posterior boundary of the ilium extends from the posterior superior iliac spine to the [...]
Psoas Minor is present in nearly 50% of the population. Whenever existent, it travels downward opposite psoas major. It bears a similarity to the plantaris muscle of the leg in form and shape, and is limited in the abdomen region. Psoas Minor Origin It arises from the side of the intervertebral disc in [...]
Iliacus is a fan-shaped muscle which creates the lateral portion of the iliopsoas muscle. Origin It emerges from: The upper two thirds of the floor of iliac fossa. Inner rim of iliac crest. Upper surface of the lateral part of the sacrum. Insertion The fibres join on and merge together with the lower part of [...]
The supraspinous ligament is a strong fibrous band, which connects the apices of the spinous processes from the C7 vertebra to the sacrum together with each other. Fibrocartilage is cultivated in the ligament, at the points of association towards the tips of the spinous processes. Structure Supraspinous Ligament It is denser and wider [...]
Sacral promontory indicates portion of the margin of the pelvic inlet and is the extended part of sacrum. The sacral promontory joins at an angle which is approximately 30 degrees and is called sacrovertebral angle. The apex is pointed downward and has an oval facet for combining together with the coccyx. Both sacral promontory as [...]
The posterior sacroiliac ligament is situated in a deep recession in the middle of the sacrum as well as ilium at the posterior side. It is strong and creates the main link of union among the bones. Structure Posterior Sacroiliac Ligament Parts The upper part a.k.a. short posterior sacroiliac ligament is [...]
