Morgagni, Giovanni Battista

(jōvän`nē bät–tēs`tä mōrgä`nyē), 1682–1771, Italian anatomist, called the founder of pathologic anatomy. He was professor of anatomy at Padua for 56 years. A meticulous observer and recorder, he contributed classical descriptions of anatomical parts (many of which are named for him), collected case histories, and carried out exhaustive postmortem examinations, as a result of which he discovered many relationships between diseases and physiological changes.

Morgagni, Giovanni Battista

 

Born Feb. 25, 1682, in Forli; died Dec. 5, 1771, in Padua. Italian physician and anatomist.

In 1706, Morgagni became a professor of practical medicine at the University of Bologna; in 1711 he went to teach at the University of Padua. As a result of his numerous observations and the data obtained from the dissection of human cadavers, Morgagni published his classic work The Seats and Causes of Disease Investigated by Anatomy (1761, vols. 1—2), in which he laid the foundation for pathological anatomy as an independent medical science. This work was of great significance for the development of clinical medicine and for the clarification of the pathogenesis and symptomatology of a number of diseases.

Morgagni’s contributions to anatomy included the first description of such anatomical formations in humans as the rectal columns (folds in the rectal mucosa), the laryngeal sinuses (depressions on the lateral walls of the larynx), and the appendices testes and the appendices vesiculosi epoophori; all these anatomical parts are named after him.

Morgagni was the author of several works on physiology and archaeology.

Notes: The body is composed of 20 segments in both sexes; 31 pairs of legs in female and 30 in male; general coloration dorsally brown; collum, head, preanal segment, anal valves, sternal region, and legs yellowish-brown; antennae brown.
At this junction, the columnar epithelium becomes cuboidal and gradually changes into transitional epithelium, extending to cover the anal valves just proximal to the pectinate line.
Chaetae on anal valves were identified after Yoshii (1996).
Anal valves with numerous acuminate chaetae; each lateral valve with chaetae a0, 2a1, and 2a2; upper valve with chaetae a0, 2b1, 2b2, c0, 2c1, and 2c2 (Fig.
Dens and posterior cephalic chaetotaxies follow Christiansen (1966) and Christiansen & Bellinger (1998), anterior head, labrum and great abdomen follow Betsch & Waller (1994), anal valves as in Betsch (1997).

VI to anal valves also occurs in Actaletidae and some members of Isotomidae, indicating that this condition must be developed several times during the evolution of different groups of Collembola.
Additional peculiarities of the new species are formal absence of seta a6 on thoracic tergites (probably present in all other members of the genus, Willemia) and uncommon chaetotaxy of anal valves.
