1. The outermost coat or serous layer of a visceral structure that lies in the body cavities of the abdomen or thorax; it consists of a surface layer of mesothelium reinforced by irregular fibroelastic connective tissue.
See also: chorion.
2. The outermost of the extraembryonic membranes that encloses the embryo and all its other membranes; it consists of somatopleure, that is, ectoderm reinforced by somatic mesoderm; the serosa of mammalian embryos is frequently called the trophoderm.
See also: chorion. Synonym(s): membrana serosa (2)

serosa

A virtual connective-tissue membrane covered by a single layer of mesothelial cells, which lines body cavities (e.g., pericardium, peritoneum, pleura) and covers the outer surface of organs (e.g., heart, intestines, and lungs) present in those cavities.

RESUMEN: Una membrana serosa cubre el higado y el parenquima hepatico el cual esta formado por hepatocitos, arterias, venas, sinusoides hepaticos y conductos biliares.
This may have resulted from transcoelomic dissemination and implantation of neoplastic cells on the ventricular serosa. Compressive and traumatic disruption of the tunica albuginea by expansile and infiltrative neoplastic cells or fibrous adhesions of coelomic viscera may have enhanced the exfoliation and consequent implantation of neoplastic cells on the ventricular serosa.
The histological sections of oviducts of group B showed three layers: serosa (external layer), myosalpinx (intermediate layer) and endosalpinx (inner layer).
The term placenta increta is used when the chorionic villi invade only the myometrium, whereas placenta percreta describes invasion through the myometrium and serosa and occasionally into adjacent organs [1].
Defects in the serosa and small lacerations can be managed with a primary closure, similar to the small intestine.
In fact, at the 32nd-34th week of development, all of the layers including the mucosa, submucosa, muscularis, and serosa become more and more similar to those of the adult stomach (27).
identified the following ultrasonographic criteria for morbidly adherent placenta: loss/irregularity of the echolucent area between the uterus and the placenta, termed 'clear space'; thinning or interruption of the hyperechoic interface between the uterine serosa and the bladder wall, termed 'bladder line'; presence of turbulent placental lacunae with high-velocity flow (>15 cm/s).
Case 4 was a 52-year-old male with pulse granulomas in appendiceal serosa and a coloenteric fistula tract secondary to perforated sigmoid diverticulitis.
La apendicitis aguda constituye la causa mas comun de abdomen agudo quirurgico de tipo inflamatorio, que inicia en la mucosa y progresa a la serosa del apendice cecal, causado por obstruccion intraluminal y consecuentemente de sus vasos sanguineos, que conlleva a isquemia distal, necrosis y perforacion [1,2]
Normal esophageal wall thickness is considered less than or equal to 5 mm on CT.1 The esophagus is surrounded by adventitia without a serosa. This lack of serosa permits esophageal pathology to spread more easily superiorly into the neck, laterally into the mediastinum or inferiorly into the upper abdomen.
