The term acetabulum means vinegar-cup and is derived from the Latin root acetum for vinegar. The Z line is a normal finding but is not seen in every study. Accessory ossification center or old fracture, posterior suprapatellar (prefemoral or supratrochlear) fat pad, anterior suprapatellar (quadriceps) fat pad, accessory anterior inferior tibiofibular ligament, superficial posterior tibiotalar ligament, superficial posterior compartment of the leg (calf), accessory extensor digiti secundus muscle, descending branch of the lateral circumflex, projects posteriorly, adjacent to the posterior colliculus, malleolar fracture (when radiographs are taken following an injury to the ankle), ossicles related to the anterior colliculus (, differentiated from other ossicles in this region by its smaller size to os subtibiale, its rounded and well-defined shape, and its anterior position, post-traumatic ossification of the deltoid ligament complex. The bone on the inner surface of the pelvis deep to the acetabular fossa is termed the quadrilateral plate and has clinical importance in classifying acetabular fractures. Morphologically the rectum is similar to the Anterior angulation of the coccyx may be a normal variant but poses a diagnostic challenge for those considering coccygeal trauma.. 3. It commences at the internal urethral orifice in the trigone of the bladder and opens in the navicular fossa of the glans penis at the external urethral meatus, which is the narrowest part of The ligament is lined by synovium. You can easily remember these layers using the mnemonic 'M.S.M.S'. The PTFL is an intracapsular but extra-synovial ligament that arises from the posterior aspect of the distal fibula and courses posteromedially to insert into the lateral tubercle on the posterior aspect of the talus.. Relations. This may be as a result of complete agenesis, defective vertical or lateral fusion, or resorption failure. type I: the coccyx is curved slightly forward, with its apex pointing caudally (~70%) type II: the coccyx is curved more markedly anteriorly, with its apex pointing straight The ligament is lined by synovium. They usually are asymptomatic although they may eventually cause painful syndromes or degenerative changes in response to overuse and trauma. Structure. Curated learning paths created by our anatomy experts, 1000s of high quality anatomy illustrations and articles. The nerves are derived from the inferior hypogastric and ovarian plexuses (via the aorticorenal plexuses) from the third and fourth sacral nerves. It can be divided into four main parts: head: thickest part; lies to the right of the superior mesenteric vessels (superior mesenteric artery (SMA), superior mesenteric vein (SMV))uncinate process: extension of the head, posterior to SMV, SMA 1. attached to "C" loop of duodenum Variant anatomy. It fuses with the shaft at ~15 years in females and ~17 years in males. The first three layers are tightly bound together and move as a collective structure.

The corpus luteum (plural: corpora lutea) is a temporary endocrine structure involved in ovulation and early pregnancy.. During ovulation, the primary follicle forms the secondary follicle and subsequently the mature vesicular follicle.. At ovulation the follicle ruptures expelling the ovum into the fallopian tube.. Acetabulum. Similar to the colon electrolytes are absorbed (sodium, potassium, chloride) and indigestible food ingredients are decomposed by anaerobic bacteria. The column principle divides the acetabulum into the anterior and posterior columns and becomes important when considering acetabular fracturesand their management. The anterior column is composed of the anterior ilium, anterior wall and dome of the acetabulum, and superior pubic ramus. It ranges from a well-formed structure in some patients to absent in others (see case 2). Furthermore the rectum is part of the continence organ and plays an important role in the mechanism of defecation. This depression is bridged with the transverse ligament of the hip, completing the circle and creating the acetabular foramen.

The complex of the medial collateral ligaments of the ankle joint is collectively called deltoid ligament.It attaches the medial malleolus to multiple tarsal bones. Os acetabuli (plural: ossa acetabuli) are small ossicles adjacent to the acetabular roof regions and may represent an unfused secondary ossification center of the acetabulum or pathological sequelae (e.g. see Mllerian duct anomalies. Copyright Additionally the intra-abdominal pressure is increased through the voluntary tension of the diaphragm and abdominal muscles (abdominal press). However the rising pressure in the ampulla leads to an increasing relaxation of the involuntary smooth corrugator cutis ani muscle and sphincter ani internus muscle (rectoanal inhibitory reflex) which is why holding in the stool for a long time involves an increasing effort.
