Definition of Pelvis
Male bone pelvis, front view. The vertical dimension is dominated by.
Female bone pelvis, front view. Predominantly the transverse dimension.
1 Meaning of PelvisThe pelvis (pelvis PNA) is the lower anatomic region of the trunk. Being a cavity, the pelvis is a funnel musculoskeletal that narrows down, limited by the sacrum, coccyx, and the coxales (which form the pelvic waist) and the muscles of the lower abdominal wall and perineum.
Generically, the term pelvis is incorrectly used to refer to the same pelvic or pelvic waist. It later delves into this.
Topographically, the pelvis is divided into two regions: the greater pelvis or (also can be called false pelvis) and the lesser pelvis or (true pelvis). The mayor, with its walls widened pelvis is solidarity forward with the lower abdominal region, the iliac pits and hypogastrium. It contains part of the abdominal viscera. The lesser pelvis, narrow funnel part, contains the urinary bladder, genitals, and terminal part of the digestive tract (rectum and year).
Pelvis bone(Coxales) iliac bones, the sacrum and coccyx articulated together form the pelvis bone, in reference to the bony structure of the pelvis. On the contrary, pelvic or pelvic waist implies a morfofisiologica reference to the part of the pelvis that participates in the joint of the lower limb, i.e. the coxales. In this regard it should be recalled that pelvic waist has its counterpart in the upper limb: the girdle.
This bone set performs several functions: gives mechanical support and protection to the pelvic organs and lower abdomen; It articulates the lower limbs to the lower portion of the trunk; allows the biodynamics of the standing position; etc.
Two surfaces and two openings can be described in the pelvis bone:
• An external surface,
• an interior surface,
• a top opening,
• a lower opening.
Outer surface• Part anterolateral: pubic symphysis + quadrilateral blade + horizontal and downward race of pubic + hole isquiopubiano;
• Side: external iliac Fossa + cotiloidea cavity + descending branch of the ischium + ischial tuberosity;
• Rear: rear side of the sacrum and the coccyx.
Inside surfaceThe cavity which limits the inside surface is divided into two parts by a narrow upper called nearly circular relief: a top, a bottom or lower pelvis or greater pelvis or pelvic excavation (cavum pelvis).
2. Definition of PelvisThe concept of pelvis refers to the body area of the mammalian (including human) that is formed with coxales bone, the coccyx and sacrum. The pelvis, located in the lower region in the case of the human body, is home to various organs of the reproductive, urinary bladder and the last part of the digestive tract.
Funnel-shaped, it is possible to split the pelvis in wholesale and retail. The greater pelvis is home to the organs of the abdomen, while the lesser pelvis the bladder, the genital organs, rectum, and the year.
Coxales bones, the sacrum and coccyx make up the so-called bone pelvis. The region that is responsible for the articulation of the lower limbs, on the other hand, is known as pelvic waist.
It is important to highlight that the pelvis of the male has several differences from the pelvis of women. In women, the pelvis has a greater openness, is shorter and has thinner walls.
When a woman suffers from a headache in the pelvis, on the other hand, it can be a symptom of endometriosis, ovarian cyst, infection or pregnancy ectopic, among other health disorders.
The position and movement of the pelvis are very important in various dances and dances. The famous belly dance, also known as Arabic dance, is based largely in the swing dancer performs with the pelvis and agitation that applied to that area.
