The Importance of Teaching Anatomical Variations to Today’s Medical Students. Int J Cadaver Stud Ant Var. 2025;6(1):20-21. Key Words: Anatomical variations; Human anatomy; Preclinical curriculum; Anatomical variants; Medical students Editorial Human anatomical variations are structures that deviate from the typical range of framework and morphology within the human body [1-2]. They are prevalent and can be accompanied by other additional variations within the same person [3,4]. Anatomical variations can be identified through dissection of human donors in anatomy laboratories as well as through findings obtained in radiological investigations and during surgical operations [3]. Thus, teaching anatomical variations during medical students’ pre-clerkship anatomy courses is essential. Not only does such knowledge enable students to succeed as practicing physicians, but it also helps to ensure the safety of their patients during treatment. Lack of knowledge of anatomical variations is at the center of innumerable medical and surgical errors [1]. In additional to causing errors, such anatomical variations can also mimic pathologic conditions, resulting in misdiagnosis, when evaluating imaging or performing physical exams. Knowledge of such variations can prevent unnecessary interventions. Equally, it is important to know which anatomical variations may represent functional challenges or impairments in normal bodily functions versus those that do not, if medical intervention is necessary. The majority of anatomical variations do not affect bodily function, so knowing the distinction between those that do and do not is crucial [1-7]. Anatomical deviation from what is presented in anatomical textbooks is quite common in human anatomy [4]. Anatomical variation is frequent, so most textbooks do notQ mention even common variations that students will encounter during their pre-clerkship anatomy dissection courses, let alone when evaluating living patients during their rotations and medical careers. Iatrogenic injury during surgery is a well-known fact in the profession. Thus, being aware of normal variants is crucial for surgeons to be able to identify and adapt their surgical preoperative planning or if a variation is discovered in real- time during the procedure [2-4,7]. Accurate interpretations of radiological imaging findings and physical examination evaluations are key to successful patient care. Knowing the location of anatomical variations during a
