Visceral Arcs

**Visceral arches** are a pair of canal arteries that are located in the lower part of the pharynx and go to the back of the throat. They are connected to autonomic nerve endings located around the pulmonary artery and upper esophagus. They are also called ventral arteries or viscerumacral arteries.

These arches have several functions for the body. Firstly, they play an important role in the growth and development of the embryo, as they contribute to the formation of gill slits. In addition, their arteries provide blood flow to the abdominal organs, including the liver, intestines, stomach and pancreas. The visceral arteries also contain sensory nerve endings associated with sympathetic fibers that transmit signals from the brain to certain organs.

There are two main dorsal branches of the visceral arches. The first is the left dorsal arch, which branches into the left and right sternocephalic branches. The second branch, the right visceral arch, branches to form the left and right vaginal arteries. Near the middle ear they connect with the lymphatic vessels of the larynx.

In men, the inferior phrenic artery arises from the sternoreticular trunk (nerve flow from this branch causes cough in men). In women, the carotid branch branches off from the inferior phrenic artery, a branch of the vagus nerve (the current creates a feeling of cold on the hands).

Both visceral arches join in the anterior wall of the pharynx into an area called the median medial region. Near the mid-posterior wall of the pharynx, the inferior dorsal angles of both arches lie at a point known as Luschka's node, where they connect the mid-medial region with the mid-thoracic wall. The laryngeal nerve passes through this zone, to which muscle fibers are attached that are involved in the formation of the muscles of the larynx and their functional anatomy.

In addition, the visceral arch is one of the targets of regional anesthesia during surgery on the upper esophageal tract.



The visceral arch is one way to use cartilage to improve sound. Applications are often found in speaker systems and headphones, which are designed to improve sound quality when listening to music. One method we can use to do this is called "visceral arches."

The visceral shackle is typically used to prevent air resonance as it passes through the system. It can be created from a variety of materials, including plastic, aluminum and other metals. Its use improves the acoustic experience, making the sound higher quality and clearer.

Another advantage of using viscerals is that they can improve sound quality across the entire frequency range. This means that viscels will improve the sound over a wide range of frequencies, and will also be an excellent addition to existing active filters.

The use of viscels has some peculiarities and is mainly related to the choice of materials. For example, production from other materials - aluminum and other metals - can be a labor-intensive process because their production requires special equipment and expensive materials. In addition, the use of metal viscellols also brings benefits only to those who use heavy iron headphones or active headphones for testing. All other listeners will feel the difference much less.
