Internal Branches

Internal branches: arterial and nervous

The splanchnic branches are the arterial and nerve branches that provide blood supply and innervation to the internal organs. Let's look at each type of branch in more detail.

Arterial branches include the rami viscerales, BNA (greater inferior artery) and JNA (small inferior artery). Rami viscerales are branches that go to internal organs such as the stomach, intestines and liver. The BNA and JNA are arteries that provide blood supply to the pelvis, including the genitourinary system and rectum.

Nerve branches also play an important role in the innervation of internal organs. Rami viscerales are nerve branches that provide internal organs with innervation from the parasympathetic nervous system. These branches include nerves that arise from ganglia in the abdominal cavity and are directed to the stomach, intestines and other internal organs.

It is important to note that the splanchnic branches can be affected by various diseases. For example, heart disease can lead to disruption of the blood supply to internal organs, and diseases of the nervous system can lead to disruption of the innervation of internal organs.

In addition, splanchnic branches may be affected during surgical interventions. For example, gastric surgery may require cutting the rami viscerales, which can lead to disruption of the innervation of the stomach.

In conclusion, the splanchnic branches play an important role in providing blood supply and innervation to the internal organs. Understanding their role and function can help in the diagnosis and treatment of various diseases associated with internal organs.

Internal branches (lat. rami viscerales) are anatomical structures that are branches from the internal organs and vessels of the body. They play an important role in the functioning of organs and systems of the body.

Arterial branches are branches from large arteries that supply blood to internal organs and tissues. They can be large or small and their function is to distribute blood to different areas of the body. For example, the arterial branches that supply the liver, kidneys and lungs provide them with oxygen and nutrients.

Nerve branches are branches from nerve trunks, which also provide communication between organs and systems. Nerves transmit signals from receptors on the surface of organs to the brain, which allows control of the functioning of internal organs. Nerve branches can be either large or small, depending on their function.

In general, the splanchnic branches play an important role in the functioning of the internal organs and systems of the body, since they provide them with the necessary resources and control their functioning.
