Adult: cylindrical shape, creamy white or pinkish in color; Male: average 15–30 centimetres (5.9–11.8 in); more slender than the female; Female: average 20–35 centimetres (7.9–13.8 in) The body is long, cylindrical, and fusiform (pointed at both the ends).
The pelvis is, in general, different between the human female and male skeleton. [14] [15] Although variations exist and there may be a degree of overlap between typically male or female traits, [14] [15] the pelvis is the most dimorphic bone of the human skeleton and is therefore likely to be accurate when using it to ascertain a person's sex ...
An estimated 807 million–1.2 billion people are infected with Ascaris lumbricoides worldwide. [2] People living in tropical and subtropical countries are at greater risk of infection. Infection by Ascaris lumbricoides is known as ascariasis. [3] It has been proposed that Ascaris lumbricoides and Ascaris suum (pig roundworm) are the same ...

The Phenice method is a technique of determining the sex of a human skeleton from the innominate pelvis. In the procedure, sex is determined based on three features: the ventral arc, the subpubic concavity, and the medial aspect of the ischio-pubic ramus. As a non-metric absolute method, it relies on the recognition of discrete male and female ...
Ascariasis; High number of ascaris worms – visible as black tangled mass – are filling the duodenum, the first portion of the bowel after the stomach, of this South African patient (X-ray image with barium as contrast medium).
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
The shape of the posterior muscular and adipose tissues seems to correspond with the general pelvic morphology. The classification is as follows the gynecoid pelvis corresponds to a round buttocks shape, the platypelloid pelvis to a triangle shape, the anthropoid pelvis to a square shape and the android pelvis to a trapezoidal gluteus region.
