The factors that associates the causes for central nervous system defects are:
- Unbalanced cerebrospinal fluid
- Deformation of the neural tube during embryonic development
Problems originating from an imbalance of CSF fluid (such as hydrocephalus) and a variety of disorders developing from abnormalities of the neural tube during embryonic development are examples of central nervous system defects (often called neural tube defects). The other choices do not result in central nervous system flaws.
<h3><u>What are cogenital disorders ?</u></h3>
An illness that is present from birth is referred to as congenital. Environmental or hereditary factors may contribute to congenital diseases. They occasionally have very little, if any, influence on a child's health and development. A kid with a congenital condition, however, may live with a handicap or health issues all of their lives.
If you're pregnant or planning a pregnancy, it's normal to be worried about congenital abnormalities, especially if that disorder runs in your family. While not all congenital abnormalities can be detected during pregnancy, some may be, and there are steps you can do to lessen the likelihood that your child will be born with one.

The acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.
What is an acrosome?
An acrosome is a unique membranous organelle that is located over the anterior part of the sperm nucleus. It is highly conserved throughout evolution.
This acrosome contains a number of hydrolytic enzymes that help the sperm penetrate the egg's coats, when secreted.
The proteolytic enzymes such as hyaluronidase and acrosin are what help the sperm penetrate the eggs coat.
Acrosome comes from the Golgi complex of the spermatid. It consists of a protein matrix core and numerous hydrolytic and glycolytic enzymes, which are necessary for fertilization.
Therefore, the acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.

Explanation:
After the blood has passed through the capillary beds, it enters the venules, veins, and finally the two main venae cavae (singular, vena cava) that take blood back to the heart. The flow rate increases again, but is still much slower than the initial rate in the aorta.
