Ascaris cross section Esophagus of an Ascaris worm. 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 ...
The female pelvis is lighter and thinner than the male pelvis. [11] The female inlet is larger and oval in shape, while the male sacral promontory projects further (i.e. the male inlet is more heart-shaped). [10] The sides of the male pelvis converge from the inlet to the outlet, whereas the sides of the female pelvis are wider apart. [12]
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 ...
Ascaris lumbricoides is a large parasitic roundworm of the genus Ascaris. It is the most common parasitic worm in humans. [1] 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.
In Olympic weightlifting, male records vary from 5.5× body mass in the lowest weight category to 4.2× in the highest weight category, while female records vary from 4.4× to 3.8×, a weight-adjusted difference of only 10–20%, and an absolute difference of about 30% (i.e., 492 kg vs 348 kg for unlimited weight classes; see Olympic ...
Have you ever wondered whether your dog or cat experiences feelings of joy and sadness? How about whether or not wild animals love and grieve? Barbara J. King, an emerita professor of anthropology ...
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.
