Fig. 1) [1]. Pompeo Pini, a jeweler, was his father, and Catarina Tosi was his mother [2]. The name Valsalva, on the other hand, originated from the place where his grandfather's family home was located. Valvalsa grew up in an upper-middle class family. At the age of 43, he married Elena Lisi, the 17-year-old daughter of a noble Bologna senator. They had six children, half of whom died in childhood. Valsalva died of apoplexy in Bologna on February 2, 1723, at the age of 57 [3].As a child, he was sent to a Jesuite school to study the humanities, mathematics, and natural sciences [1,3]. Interested in anatomy and physiology, Valsalva continued his education at the University of Bologna and graduated at the age of 21 [2]. At this University, he was a student of Marcello Malpighi (1628-1694), known as the discoverer of microscopic anatomy [1]. By the time he graduated, a plague epidemic in Bologna spread throughout the city. Therefore, as soon as he graduated, he was appointed as an inspector of public health services in Bologna. While performing this duty, he treated many important people, including the governor of the city, with his clever clinical judgment [1,3]. Afterwards, the academic community appreciated his achievements and declared him Professor of Anatomy, and he became * Gkionoul Nteli Chatzioglou

Whitnall tubercle (WT) of the zygomatic bone is used as an anatomical landmark in some surgical approaches to the orbit. The authors aimed to determine the localization of WT by using some palpable bony landmarks and to reveal its morphological and morphometric features. Three hundred twenty-two zygomatic bones (167 right and 155 left) belonging to adults of unknown sex, were examined. An acetate prepared by drawing a clock with a dial on it was used to determine the localization of WT according to marginal tubercle and zygomatic arch. Distances between WT and frontozygomatic suture and lateral margin of the orbital rim were measured with digital calipers. One zygomatic bone had double tubercles, thus 321 bones were taken into consideration. Whitnall tubercle was determined in 284 of 321 zygomatic bones. 181 were classified as small, 10 as medium, and 93 as large. The position of the WT according to the marginal tubercle was at the 8, 9, and 10 o'clock positions on the left, and at 2, 3, and 4 o'clock on the right. The position of the WT according to the zygomatic arch was at the 9,10 and 11 o'clock positions on the left, and at the 1 and 2 o'clock positions on the right. Distances between the WT and lateral margin of the orbital rim and the frontozygomatic suture were measured meanly as 1.94 ± 0.31 mm and 8.17 ± 5.82 mm, respectively. The authors believe that the data obtained regarding WT will contribute to anatomy and surgical procedures of the related region.

Objective: The nutrient artery which enters through the nutrient foramen (NF) provides blood circulation and nutrition in long bones. This supply is essential during the growing period, the early phases of ossification, and in some surgical procedures. This study aimed to investigate NF in adult human ulnas in the Turkish population. Methods: For this study, 155 (70 right and 85 left) Turkish dry adult human ulnas were used. The presence, number, and patency of NF were recorded as well as its topography and direction. The vertical distance between the most proximal point of the olecranon and the proximal edge of the NF (DONF), and the longitudinal distance between the most ventral point of the coronoid process on the sagittal plane and the proximal edge of the NF (DCpNF) was calculated. Additionally, the foraminal index (FI) was assessed. Results: Single and double NFs were in 139 ulnas (89.67%), and 3 ulnas (1.94%), respectively. NFs were not observed in 13 ulnas (8.39%). The majority of NFs (93.12%) were situated on the anterior surface of the ulna. The direction of all NFs was towards the elbow. The mean DONF and DCpNF were 9.48 ± 1.57 cm, and 6.68 ± 1.44 cm, respectively. The FI was 37.45% in ulnas with a single NF, while it was 41.46% in ulnas with a double NF. Conclusion: Our study has presented additional information such as the FI of ulnas with 2 NFs, and the distance between the coronoid process and NF in the Turkish population.

Objective: The aim of our study is to reveal the errors that can be encountered during the shooting of photogrammetric studies on the lower extremities. Methods: We revealed the necessary tools that used during photogrammetry measurements of the lower limb. Also, the errors have been encountered of our two previous studies performed on photogrammetry of lower limbs. The technical errors or incorrect positioning of 20 from 220 volunteers were encountered. Results: The identified errors of 20 volunteers’ photographs related to lower limb were about the inadequate quality image, calibration, poor lightining, positioning error of trunk or parts of lower limb and clothes that cover the anatomical points affected the measurements. Conclusion: Photogrammetry is an important and useful tool for evaluation, diagnosis, treatment, and efficacy monitoring. In anatomy, it is frequently used as a time-saving method in terms of measurement and evaluation in the laboratory, which can be applied and repeated for research. For this reason, errors that occur during the lower extremity have been reported and we think that it will be useful for studies on this part of the body and can be a guide.
