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 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 ...
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.
In the absence of a Y chromosome, the fetus will undergo female development. This is because of the presence of the sex-determining region of the Y chromosome, also known as the SRY gene. [5] Thus, male mammals typically have an X and a Y chromosome (XY), while female mammals typically have two X chromosomes (XX).
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 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. [8]
The human skeleton is not as sexually dimorphic as that of many other primate species, but subtle differences between sexes in the morphology of the skull, dentition, long bones, and pelvis exist. In general, female skeletal elements tend to be smaller and less robust than corresponding male elements within a given population.
As might be expected, the contents of the urogenital triangle differ greatly between the male and the female. Some of the components include: [1] Posterior scrotal nerves / posterior labial nerves; Urethra; Vagina; Bulbourethral gland / Bartholin's gland; Muscles Superficial transverse perineal muscle; Ischiocavernosus muscle; Bulbospongiosus ...
