Anal Canal

The Anal Canal is an organ located in the area of ​​the anal curvature. This channel is about 2-3 centimeters long and surrounds the end of the rectum. As mentioned earlier, it is surrounded by muscles called sphincters.

The Anal Canal consists of two parts - the outer part, called the peri-rectum, and the inner part, which is inside the sphincter and is called the inner rectum. The outer part of the Posterior canal is covered with skin, muscle, and sometimes mucous membrane. The inner part is covered by muscle and is covered by the back and front of the rectus muscle. The posterior canal connects the rectum and perineum.

The differences between these two parts of the Rear Canal are that the outer part of the Rear Canal opens with the anus, which is located on the perineum. To understand the mechanism of operation of the rear-wheel drive channel, it is necessary to know human anatomy and its internal structure. The external canal of the posterior aqueduct is supplied with blood from the posterior anastasia and posterior cutaneous nerve of the thigh. The internal canal of the Anus has autonomic innervation, that is, it does not have a motor system. In addition, the external canal Posterior is characterized by the presence of muscle fibers that provide locking of the canal. The external sphincter muscles have many layers of muscles and provide closure to the external canal of the retroduct. The internal sphincter muscles are characterized by a thinner structure and are supported by muscle fibers. They ensure retention of intestinal contents by strengthening and weakening tone.

The functions of the Posterior channel are to perform

The anal canal or Anal Canal is the final section of the rectum, which is surrounded by a group of sphincter muscles. It is covered by a layer of epithelium and lining mucous membrane. This area is connected to the anal exit by the anal canal. The anal canal consists of many folds of the mucous membrane, which have different lengths and widths. This gives it a muscular tube-like structure. It takes part in the creation of the anal dam, which is responsible for closing the anus during bowel movements and preventing the passage of feces. The Posterior channel is also of great importance for human health, since it is
