Andy's and my pig (Sir Oinks A LOT) was just about like all the other pigs in the room. I found this out because he had a urogenital opening behind the umbilical cord. .
Cranial Cavity:.
The cranial cavity consits of the nervous system in general. It is located on the dorsal/anterior of the fetal pig. It pertains to the anterior section of the human body. The major organs in the cranial cavity are the brain and the spinal cord. Both of theses are parts of the nervous system. The function of that system is to take physical stimuli from environments and process them and respond to what is happening. Both the brain and spinal cord receive information from sensory nerves. Three major parts of the brain are the Cerebrum, the cerebellum and the medulla oblongata. .
The cerebrum is the largest of the three, it has right and left hemispheres. It is used for the interpretation of impulses and coordination of voluntary movements. It is divided into frontal, temporal and parietal regions. Mostly used for learning and memory.
The cerebellum's main function is to control the reflexes for skeletal muscle movements. It also helps with your balance.
The medulla oblongata is the most caudal and lead to the spinal cord. Its main functions is to regulate breathing, digestion and sweating.
Thoracic Cavity:.
The thoracic cavity contains the respiratory and cardiovascular systems. It is located posterior from the cranial cavity and anterior to the abdominal cavity.
The respiratory system is responsible form bring oxygen to the blood stream. The lungs allow air/oxygen to enter the blood stream. The trachea is a tube that is reinforced with cartilaginous rings which prevent the collapse of the trachea during inhalation. As you inhale through your mouth or nose the passage of air/oxygen goes form the naso pharynx through the glottis to the larynx and then to the trachea. The larynx of the voice box in humans allows noise, or voice to be made by vibrations.

The fetal pigs that are used for dissection come from the meatpacking industry and are a "by-product". The breeding pigs, from which the fetal pigs are taken from, are confined to stalls barely larger then their bodies. ... The stalls are stacked and excrement from pigs higher up falls on those below. Often the stench of ammonia is too overpowering for farmers, who only spend minutes a day in pig buildings. ...

In 1984 a newborn pig named "Baby Fae" lived an additional 20 days with a heart from a baboon. ... The reason why scientists chose pigs is because pigs have organs similar in shape, size, and function to human organs. ... Pigs organs contain 2 genes called GGTA1. ...

The Physiological variations amongst rats, rabbits, dogs, cats, pigs, and humans are huge, meaning that not only do animal experiments hurt animals and waste money, they harm and kill people too (PETA). ...

Research indicates that human cloning is a threat to the health of both mother and child. () Animal studies on reproductive cloning show an extremely elevated incidence of fetal disorders, spontaneous abortions, and malformation and death among newborns.() This is why I agree with part of the article and think that it would be careless and unethical to clone human beings. It seems incredibly unfair to use people as "guinea pigs" for something that has so many problems, or even animals for that matter. ...
For example, if someone was to clone a forty year old woman, you wouldn't get another forty year old woman, you would get an embryo that would have to be implanted in a woman's uterus and pass through all of the normal stages of fetal development before birth. ...

The hormone succeeded in making the pig grow faster without giving it any extra food, but it suffered terribly from the side effects. ...
