Equine Stomach Development in the Fetal Period: An Anatomical, Topographical, and Morphometric Study.

Abstract: Studies of equine stomach prenatal development are very rare, and descriptions usually focus on the processes taking place in the embryonic period. Only general information about gastric organogenesis in the fetal period is available in embryology textbooks on domestic mammals. The material for our study included twenty half-breed horse fetuses divided into three age groups on the basis of known fetal age (verified using the CRL method). Our study consists of the topographical, morphological, and morphometrical description of stomach development between the 4th and 11th months of gestation. Even though the skeletotopy, syntopy, and holotopy of the stomach in the fetal period seems to be relatively unchanged, the organ shape and the proportions between its anatomical parts differed in fetuses from the three age groups. The achieved results were statistically elaborated to estimate the dynamics of the stomach shape. This can be described as changing from medium-wide to wide and from slightly bent to sharply bent. A nonlinear correlation of all metric values with CRL in all age groups was observed. A positive allometric growth rate of different intensity was seen in all metric parameters. All the values increased as the fetal period progressed. Only the parietal surface growth rate gradually changed from strongly positive allometric in the first age group to strongly negative allometric in the third age group. A difference between the non-glandular and glandular mucosa of the stomach was visible in the first group. Development of a well-distinguishable plicated edge margin began in the second age group together with gastric pits and gastric areas. The third age group showed a well-developed gastric groove and angular incisura.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article is a detailed study on the development of the stomach in horse fetuses from the 4th to the 11th month of gestation looking at topographical, morphological, and morphometrical aspects.

Objective of the Research

  • This research aims to shed light on the anatomical, topographical, and morphometric development of the equine stomach during the fetal period, a topic that has been rarely studied in depth. The desire is to fill these knowledge gaps and contribute new, robust data to the understanding of equine fetal development.

Methodology

  • The researchers utilized twenty half-breed horse fetuses as the subjects of their study. These fetuses were divided into three age groups based on their known fetal age, established and verified with the Crown Rump Length (CRL) method.
  • The research specifically examined changes to the stomach’s topography, morphology, and morphometry between the 4th and 11th months of gestation.

Key Findings

  • The research discovered that while the position (skeletotopy, syntopy, and holotopy) of the stomach doesn’t change significantly during the fetal period, the organ’s shape and proportions of its anatomical parts are altered across the three age groups.
  • The shape of the stomach specifically transitions from being medium-wide to broad, and from slightly curved to sharply bent as gestation progresses.
  • All metric values associated with the stomach correlated nonlinearly with CRL across all age groups, indicating a consistently positive but varying growth rate throughout the fetal period.
  • Peculiarly, the growth rate of the stomach’s parietal surface was found to shift from strongly positive allometric in the first age group to strongly negative allometric in the third age group.
  • The development of the non-glandular and glandular mucosa in the stomach was discernible from the first group.
  • Noticeable development of a plicated edge margin along with gastric pits and areas was seen in the second age group, while the third group exhibited a well-developed gastric groove and angular incisura.

Conclusion

  • This study provides valuable insights into the development of the equine stomach during the fetal period. It offers a deeper understanding of the anatomical and topographical transformations the stomach undergoes during gestation, revealing key changes and growth patterns at different stages.
