Pigs have 14 rib bones. They are attached to the spine and are usually divided into four popular cuts: Baby back ribs, spareribs, St. Louis cut ribs, and rib tips. Starting at the top are the baby backs, closest to the backbone, nestled beneath the loin muscle.
There are three types of muscle in the pig: Involuntary or smooth muscle – Found in the digestive and genital systems and the blood vessel walls. Cardiac muscle – The heart consists largely of this muscle. It is involuntary.
Pigs spend the bulk of their time rooting and foraging for food, which involves them digging in mud, soil and sand for anything edible. The pig has a highly specialized nose just for this purpose. The muzzle ends in a blunted upper lip which is a flexible disc encircling the two nostrils.
What is the function of the spinal cord in a pig?
The spinal cord is responsible for transmitting the electrical impulses from the brain to these branches. Peripheral nervous system – Nerves leave the brain and the spinal cord and transmit the electrical impulses throughout the body. This system is the voluntary one that is under the pig’s control.
This system partly controls the heart beat, movement of the muscular walls of the digestive system, the hormonal systems and the excretory systems. There are a number of important bacterial and viral diseases that cause clinical nervous signs in the pig.
What do the bones of a pork roast look like?
They are curved, round bones, close together, and most of the meat is on top of the bones, cut from the underside of loin muscle. As you move further from the spine, the bones get larger, flatter, straighter, and wider apart with more meat between them. There is more fat marbling in the meat as you go further from the spine and closer to the belly.
