Anatomical and clinical aspects of the blood supply of the sinoatrial node.

BACKGROUND: The recent study of the variations of the origin of the sinoatrial node and on the "arterial network of the perinodal sinusal area" in normal hearts points out the importance of this network. PURPOSE: Report on a case of patient with syncope of ischemic etiology. CONCLUSION: In this patient the arterial network did not protect the node from the ischemia caused by the obstruction of the artery of the sinoatrial node.

History of the anatomy of the funiculus umbilicalis in mammals.

The authors, based on a bibliographic search, present a brief survey of the history of the anatomical aspects of the funiculus in mammals, including the evolution of their interpretation and their relationship with the evolution of scientific and technological approaches to their study.

Vasculature of bovine placentas studied by scanning electron microscopy of corrosion casts.

Corrosion casts, obtained after injection of Tensol or Mercox, from 10 placentas of Holstein breed cows, were studied. The investigation was performed in fetal cotyledons, which are attached to uterine caruncles to form units, called placentons. Arteries and veins form, together, vascular cylinders, with the venous half cartridge partially surrounding the arterial one. The morphological differences between arterioles and venules concern the type of distribution, branching, surface (nuclei, oblique folds, anular narrowings).

Pancreatic arteries and anatomicosurgical segments in dogs.

The distribution of the arteries supplying the pancreas was studied in 22 adult dogs (7 females and 15 males) of mixed breed. The pancreas was divided into 2 lobes, 4 sectors and 6 anatomicosurgical segments. These segments are defined as territories recognizable anatomically and surgically removable. The division and subdivision of the pancreas and the segmental arteries were the following: Left Lobe: Omental sector: I. Proximal segment: splenic a. II. Middle segment: splenic a. III. Distal segment: gastroduodenal and right gastro-omental Interpapillary sector: IV. Juxtaduodenal segment: cranial pancreaticoduodenal a. Right Lobe: Distal sector: V. Distal segment: cranial pancreaticoduodenal a. Proximal sector: VI. Proximal segment: caudal pancreaticoduodenal a.

Anatomical variations of the abducent nerve in humans.

Anatomical variation of the nervus abducens in human encephali were found and described. They consisted of (1) an unusual trifurcation of the abducent nerve, limited to the extradural portion of the neural trunk (1.4% of the cases) and (2) the duplicity (11.1%) of the neural trunk, starting before reaching the orbit and ending before reaching the m. rectus lateralis. The possibility of correlating these variations with clinical aspects and forensic interpretations is mentioned.
