Female anatomy is a term used to refer to the parts of the human body that belongs solely to females, rather than both females and males. The female reproductive organs, for example are consider female anatomy, but the heart and lungs are not.
There are differences that we all have in human anatomy, women possess internal genitalia (the vagina, uterus and ovaries) for the production of eggs and the development of human embryos and Men possess external genitalia (the penis, scrotum and testes) for the production and delivery of sperm. Most physiological differences between women and men occur due to differences in the endocrine systems during critical periods of development, such as foetal growth and puberty.
The functions of the endocrine systems in women and men lead to other physiological differences throughout life. For example, Women, produce a fine hair follicle called ‘vellus hairs’ in fewer areas of the body then men. Men on the other-hand, men produce a more course and visible type of hair follicle called terminal hairs on the chest, abdomen, face and back.
Great differences are also present in the skeletal and muscular systems in men and women. Typically, men possess denser, stronger tendons, ligaments and bones than women, and men generally have more muscle mass. This leads to differences in physical strength and the metabolic processes of calorie expenditure and storage. In comparison, women typically possess a skeletal system that is less robust and smoother in structure than that found in males
Studies that have looked at the anatomical differences in the brains of females and males have focused on:
Total brain size
In adults, the average brain weight in than the average brain weight in women is about 11-12% less than her male counterpart. This does not suggest that due to the larger brain, males are smarter than females.
It is reported that a woman’s brain has a larger corpus collusum, a tissue that separates the right hemisphere from the left hemisphere, which means women can transfer data between these 2 halves of the brain faster than men.
Two areas in the frontal and temporal lobes related to language (the areas of Broca and Wernicke) are significantly larger in women, thus providing a biological reason for women’s notorious superiority in language-associated thoughts and verbal expressions.
Inferior parietal lobule (IPL)
It is a brain region in the cortex, which is significantly smaller in women than in men. It is related to the perception of our own affects or feelings.
Females, on average, have a larger deep limbic system than males. Due to the larger deep limbic brain, women are more in touch with their feelings; they are generally more able to express their feelings than men. They have an increased ability to bond and be connected to others.
Many behavioural differences have been reported for men and women. These differences appear in the way women and men:
Judge speed of things
Carry out mental mathematical calculations
Orient in space
Visualize objects in three dimensions
Express their emotions
Show affection verbally and non-verbally
Socio-biologist, Edward O. Wilson, said that human females tend to be higher than males in empathy, verbal skills, social skills and security seeking, among other things, while men tend to be higher in independence, dominance, spatial and mathematical skills, rank-related aggression, and other characteristics.
Interestingly, the female’s emotions are in both hemispheres of the brain, while male brains separate language in the left, and emotions in the right. This helps explain why the male brain has a hard time expressing its feelings verbally.
Tests show that women generally can recall lists of words or paragraphs of text better than men. On the other hand, men usually perform better on tests that require the ability to mentally rotate an image in order to solve a problem.
Mental rotation is thought to help people find their way. This in no way reflects on women’s abilities in the same area, they are just different. Scientists believe that women may rely on their memory and recall landmarks to find a destination and men are more likely to navigate by estimating distance in space and orientation.
