Artery of the Inferior Anterior Segment

The artery of the inferior anterior segment (a. segmenti anterioris inferioris) is an artery that passes through the lower part of the body and supplies the lower anterior part of the body. It is one of the branches of the common iliac artery and branches from it in the lower part of the thigh.

The artery of the lower anterior segment arises from the common iliac artery in the lower part of the pelvis. It passes through the anterior abdominal wall and enters the groin area. The artery then passes through the inguinal canal and exits into the lower abdomen. From there it continues downwards and passes through the lower part of the anterior abdominal wall.

The main branches of the artery of the lower anterior segment are:

  1. The inferior epigastric artery (a. epigastrica inferior) - branches from the artery of the lower anterior segment and passes down through the anterior abdominal wall, feeding the abdominal muscles and diaphragm.
  2. The inferior epigastric artery (a. umbilicalis inferior) - passes through the upper part of the anterior abdominal wall and nourishes the abdominal muscles, skin and internal organs.
  3. Iliopsoas artery (a. iliopsoas) - departs from the artery of the lower anterior segment and runs along the lower back, feeding the lumbar muscles and skin.
  4. Lateral sacral artery (a. sacralis lateralis) - departing from the artery of the lower anterior segment, passes along the lateral surface of the sacrum and nourishes the skin of the sacral region.

In general, the inferior anterior segment artery plays an important role in supplying the anterior portion of the body, especially the muscles and skin. Its branches provide blood supply to the lower abdomen, groin area, anterior abdominal wall, lower back and sacral area.



The artery of the lower anterior segment (a.segmenti anterioris inferiors) is one of the arteries of the head and neck, which is a branch of the external carotid artery. It passes through the neck and enters the lower part of the face, where it supplies blood to the skin, muscles and other tissues.

The artery of the inferior anterior segment begins at the level of the lower edge of the thyroid cartilage and passes down the anterior surface of the neck. It is divided into two branches: anterior and posterior. The anterior branch passes forward and supplies blood to the front of the neck and head. The posterior branch runs backward and supplies the back of the neck and head.

An important clinical significance of the artery of the lower anterior segment is its connection with the vessels of the brain. If this artery is damaged, bleeding into the brain can occur, which can lead to serious consequences. Therefore, for any neck and head injuries, it is necessary to conduct a thorough examination and diagnosis of the artery of the lower anterior segment.

It is also worth noting that the artery of the lower anterior segment plays an important role in the nutrition of the face. It supplies blood to the facial muscles, skin and mucous membranes. Poor circulation in this area can lead to various diseases and pathologies, such as ulcers, dermatitis and other problems.

In conclusion, the inferior anterior segment artery is an important artery of the head and neck. Damage to it can lead to life-threatening consequences, so careful diagnosis and treatment of any injuries to this area is necessary.
