“…Pig specimens have been supplied and used in biological, medical and anatomical curricula as science teaching materials (Akoma et al, 2015; Anetai‐Midarikawa et al, 2021; Barr & Herzog, 2000; Kojima et al, 2022; Sekiya, 2018). Several detailed anatomical findings in such pig specimens (mainly in the foetal pigs) have recently been accumulated, for example, the anatomical characterizations of the CCS (Mingsakul et al, 2014), coronary arteries (Dai et al, 2020; Rodrigues et al, 2005), internal iliac artery (Anetai et al, 2021), sternocleidomastoid muscle and its innervation (Fuse et al, 2019), and anatomical analysis of congenital anomalies of phrenic nerve and diaphragm (Sekiya et al, 2020). These reports of pig anatomy have provided valuable findings and suggestions in terms of comparative anatomy, while also contributing to the educational significance of pig specimens as medical and anatomical teaching materials.…”
