Purpose: This study aimed to compare the students' scores of the spot (spotter/classical/traditional/tag/ring/bell-ringer) test (3D environment) performed in the laboratory with the slide test (gross anatomy images) (2D environment) in the class. The observation of our department regarding both types for practical examination was reported, in terms of exam marks of the students. Both are preferred as the practical examination types for gross anatomy course our in medical faculty.

It was aimed that the morphometric development of the hyoid bone throughout the fetal period be anatomically researched and its clinical importance be evaluated. A total of 90 human fetuses (44 male, 46 female) whose ages varied between 18 and 40 gestational weeks and without an external pathology or anomaly were involved in the study. The fetuses were divided into groups according to gestational weeks and trimesters.

Introduction: We aimed to investigate the morphometric development of the cranial base and its related structures, and their growth rate changes from the ninth gestational week to full term in a large group of human fetuses.

Methods: We selected 203 (109 male, 94 female) fetuses between 9 and 40 weeks of gestation and without any external anomalies. From each fetus, standard lateral and posteroanterior cephalometric images were taken using a dental digital panoramic and cephalometric x-ray machine.

Objective: The aim of the present study was to examine the effects of chronic mild stress (CMS) induced before the fertilization on gestational maternal weight, length of gestation, and postnatal morphometric development.

Material And Method: Study is carried out on 18 Wistar albino rats; six females in the stress group, six females in the control group, and six males to be used for mating. CMS was induced in rats of the stress group for 4 weeks, followed by a post-CMS waiting period of 5-weeks.

Purpose: In this study, our objective was to investigate the development of the gallbladder, its morphological structure and relationship with the adjacent organs during the fetal period.

Materials And Methods: A total of 118 human fetuses (60 males, 58 females) between 9 and 40 weeks of gestation without any external anomaly or pathology were included. They were divided into four groups according the gestational age: I (9-12 weeks), II (13-25 weeks), III (26-37 weeks) and IV (term, 38-40 weeks).

Objective: This study was aimed to determine the location and development of the spleen in the human fetuses.

Materials And Methods: The study was carried on 141 dead human fetuses aged between 9 and 40 weeks with no marked pathology and anomaly in the years 2002-2003. The location of spleen with the neighboring structures, the existence of accessory spleens, notches on the borders, fissures on the surfaces, major ligaments and the shape of spleen and its hilum were established.

The aim of the present study was to determine the dimensions of the mandible during the fetal period, the relationship between the growth rates of the angle of the mandible and the dimensions of the mandible. Furthermore the angle of union of the two halves of the body of the mandible on the horizontal mandibular plane, which was not described elsewhere, is explored in this study. One hundred and sixty-one human fetuses (83 males and 78 females) without any cranio-facial or mandibular asymmetry, external pathology or anomaly and aged between 9 and 40 weeks of gestation were used in the study.

Article Synopsis
  • The study investigates colon types and morphological changes in fetuses from 10 to 40 weeks gestation, focusing on those without external pathologies.
  • It evaluates the types of colon in two parts: the segment between the ileal orifice and sigmoid colon, and the sigmoid colon itself, detailing the macroscopic measurements of wall thickness and diameter.
  • Results show a significant variation in colon types across trimesters, with adult-type colons becoming more common in the third trimester, and notable development in structures like haustra and tenia coli as pregnancy progresses.

Article Synopsis
  • - The study explored the morphologic structures of the jejunum and ileum in 131 human fetuses, analyzing various parameters such as size, localization, and thickness of intestinal layers at different gestational ages.
  • - No significant differences related to sex were found, though macroscopic measurements increased with gestational age; the thickness of the tunica serosa remained stable.
  • - The findings aim to enhance understanding of fetal intestinal development and could assist in diagnosing and treating related anomalies and pathologies.
