1.1 Introduction
Human anatomy refers to the study of the structure and organization of the human body. It encompasses the identification and description of bodily structures, including organs, tissues, and systems, and their relationships to one another (Drake, Vogl, & Mitchell, 2020). The relationship between human anatomy and anatomical pathology is a cornerstone of medical science, providing the foundational knowledge necessary for diagnosing and treating diseases (Drake, Vogl, & Mitchell, 2020).
Advancements in medical technology, such as imaging techniques and molecular pathology, have further deepened the connection between anatomy and pathology. These technologies allow for detailed visualization and analysis of anatomical structures and pathological changes, enhancing diagnostic accuracy and treatment efficacy (Sternberg, Mills, & Carter, 2021). The interplay between human anatomy and anatomical pathology is evident in various medical practices (Rosai, 2011).

1.2 Background of Study
In ancient civilizations, early anatomists like Hippocrates and Galen laid the groundwork for the study of human anatomy. Their observations and dissections provided the first comprehensive descriptions of human body structures (Nutton, 2004). However, these early anatomical studies were often limited by cultural and religious taboos against dissection, which hindered a deeper understanding of the human body.
The development of anatomical pathology as a distinct discipline began in the 19th century with Rudolf Virchow, who is often regarded as the father of modern pathology. Virchow's cell theory posited that diseases originated at the cellular level, fundamentally linking anatomy and pathology. His work emphasized the need to study diseased tissues to understand the underlying causes of illness, thereby cementing the relationship between anatomy and pathology (Ackerknecht, 2016).
The advent of microscopy in the 17th and 18th centuries further strengthened this relationship. Antonie van Leeuwenhoek’s pioneering work with microscopes allowed for the visualization of cells and microorganisms, providing insights into the microanatomy of tissues and the pathological processes occurring within them (Gest, 2004). in the 20th century, advancements in medical imaging technologies such as X-rays, CT scans, and MRI further bridged the gap between anatomy and pathology. These technologies allowed for non-invasive visualization of the internal structures of the body, facilitating the diagnosis and monitoring of pathological changes in their anatomical context (Sternberg, Mills, & Carter, 2021). Radiology emerged as a critical field that relies on anatomical knowledge to interpret images and diagnose diseases accurately.
Today, the integration of human anatomy and anatomical pathology is evident in medical education and practice. Medical students are trained to correlate anatomical structures with pathological findings, enhancing their diagnostic skills and clinical decision-making. Multidisciplinary approaches in medicine, combining the expertise of anatomists, pathologists, and radiologists, have improved patient outcomes and advanced medical research (Kumar, Abbas, & Aster, 2018).
Anatomical pathology emerged as a distinct discipline in the 19th century, driven by the need to understand the underlying causes of disease at a tissue and cellular level. Rudolf Virchow, often referred to as the father of modern pathology, revolutionized the field with his theory that diseases are caused by alterations in cells, thus linking pathology directly to cellular and tissue changes observed through anatomical studies (Ackerknecht, 2016). His work underscored the importance of correlating clinical symptoms with anatomical and pathological findings, a principle that remains central to medical diagnostics today.
The development of advanced imaging technologies, such as MRI and CT scans, has further integrated the study of anatomy with pathological investigation. These technologies allow for non-invasive visualization of the internal structures of the body, facilitating the identification of pathological changes in their anatomical context. As a result, radiology has become an essential tool in both anatomy and pathology, bridging the gap between clinical practice and diagnostic precision (Sternberg, Mills, & Carter, 2021). Modern anatomical pathology encompasses various subspecialties, including surgical pathology, cytopathology, and forensic pathology. Each of these areas relies heavily on a deep understanding of human anatomy to accurately diagnose and interpret disease states. For instance, surgical pathologists examine tissues removed during surgeries to determine the presence and extent of diseases like cancer, making anatomical knowledge crucial for identifying tumor margins and guiding surgical interventions (Rosai, 2011).
Kumar et al., (2018) asserted that, educational advancements in medical curricula have emphasized the integration of anatomical and pathological sciences. Medical students and professionals are trained to correlate anatomical structures with pathological findings, enhancing their diagnostic capabilities and clinical decision-making processes (Kumar, Abbas, & Aster, 2018). Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the relationships between human anatomy and anatomical pathology.
1.3 Statement of Problems
Investigation revealed that there is variability in anatomical structures among individuals, which complicates the application of standardized pathological assessments. Anatomical variations can obscure pathological changes, making it difficult for pathologists to accurately interpret findings. This challenge necessitates a more personalized approach to pathology, which is not always feasible in clinical settings (Kumar, Abbas, & Aster, 2018).
The rapid advancement of imaging and diagnostic technologies has also highlighted the problem of insufficient training for medical professionals. Many clinicians and pathologists are not adequately trained to use and interpret these advanced tools, leading to underutilization or misinterpretation of diagnostic data. This technological gap further exacerbates the disconnect between anatomical and pathological studies (Sternberg, Mills, & Carter, 2021).
Furthermore, there is a lack of interdisciplinary collaboration between anatomists, pathologists, and clinicians. Effective diagnosis and treatment require a cohesive understanding and communication across these specialties. However, siloed medical education and practice often hinder such collaboration, leading to fragmented care and missed opportunities for comprehensive disease management (Ojo, 2020).
Additionally, ongoing medical research faces the challenge of limited access to high-quality tissue samples and anatomical data. Ethical and logistical issues in obtaining and handling human tissues for research purposes restrict the ability to conduct thorough pathological studies. This limitation hampers the development of new diagnostic and therapeutic strategies that rely on a deep understanding of both anatomy and pathology (Rosai, 2011).
