Pregnancy and Childbirth- How Women are Adapted.

It’s a miracle that women are able to form a person from a ball of cells which can then be pushed out of a hole that is tiny in comparison. Therefore, I decided to research what it is that makes this reproduction possible.

The story that all teenage girls are taught during sex-education classes is that women can give birth because they have wider hips and women that have slightly smaller hips are now more commonly told that they can’t have a natural birth or that their natural birth will be more laboured or longer in duration is slightly untrue.

Antidepressants are drugs developed to suppress the symptoms of depression (too obvious?)

There are two main causes of depression that are treated by antidepressants; if the person has low serotonin levels they are mostly treated with SSRI’s; selective serotonin re-uptake inhibitors to increase this level. Serotonin is important to brain activity because it is a neurotransmitter and so sends signals between neurons and although scientists are still unsure of why, especially since the level of serotonin can only be monitored in the bloodstream currently and not the brain, the site of neurological activity. Because of this uncertainty, it is unknown why serotonin relieves the symptoms of depression Continue reading “Antidepressants- Are Pills The Way Forward?”

Mitochondria- Nature’s Bank

Mitochondria are the organelles that release ATP, which is how energy is stored in living things and allows whole organisms, like the human body to function which is pretty impressive for such a microscopic (literally) body. In eukaryotic cells, usually cells that have a nucleus or other organelle such as a plant or animal cell but not bacterial cells, there are about 1,000 mitochondria in each cell and the knowledge we now have in the features and functions of the organelles are due to access to electron microscopy.

The discovery of mitochondria was in 1886 when Richard Altman used dye to identify, although Continue reading “Mitochondria- Nature’s Bank”
