The embryology of the inguinofemoral area: an overview

Abstract

This paper is an essay to understand the formation of the inguinal and femoral areas by means of an overview of the embryogenesis of the anterior abdominal wall below the umbilicus, as well as by examining the genesis and the descent of the gonads.Developmental considerations of the femoral canal lead to a discussion of the potential explanations for the developmental formation of a femoral hernia sac. The main argument against the congenital origin of femoral hernia is its rarity in infants and children. Despite the lack of irrevocable proof of a developmental defect, femoral hernias do occur in children and they can become strangulated. Some attractive embryological theories which attempt to explain this fact are discussed.

Variations in the Pattern of Formation of the Abdominis Rectus Muscle Sheath among Kenyans

“…The pattern of formation of the rectus sheath may be explained by its embryogenesis (Walmsley, 1937;Skandalakis et al, 1997). The anterior abdominal wall is first formed by ectoderm and parietal mesoderm which form somatopleura (Skandalakis et al).…”

WITHDRAWN: Genome-wide association analysis of inguinal/scrotal hernia in pigs using specific length amplified fragment (SLAF) sequencing

“…Inguinal and scrotal hernias, which occur in the weak areas of the inguinal canal [1,2] or the processus vaginalis [3,4], are some of the most frequent congenital disorders observed in pigs and humans [5,6]. They cause severe economic loss in the pig breeding industry [7].…”

A new method of spermatic cord mobilization in herniorrhaphy

“…Most of the previous anatomic studies regarding the spermatic cord have focused on its layers and contents instead of its relationships with surrounding structures other than the internal ring (Skandalakis et al, 1997). The external structure of the spermatic cord inside the inguinal canal is the cremasteric fascia, which arises from the internal oblique fascia, and the internal structure is the internal spermatic fascia, which arises from the transversalis fascia (Skandalakis et al, 1989).…”
