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.
