Gross anatomy is the study of
anatomy at the visible or
macroscopic level.
The counterpart to gross anatomy is the field of

also known as microscopic anatomy or microanatomy, is the branch of biology that studies the microscopic anatomy of biological tissue (biology), tissues. Histology is the microscopic counterpart to gross anatomy, which looks at large ...

Gross anatomy of the
human body or other animals seeks to understand the relationship between components of an organism in order to gain a greater appreciation of the roles of those components and their relationships in maintaining the functions of life. The study of gross anatomy can be performed on deceased organisms using
dissection or on living organisms using
medical imaging. Education in the gross anatomy of humans is included training for most

Techniques of study
Gross anatomy is studied using both invasive and noninvasive methods with the goal of obtaining information about the macroscopic structure and organisation of
organs and organ systems. Among the most common methods of study is
dissection, in which the corpse of an animal or a human
cadaver is
surgically opened and its organs studied.
Endoscopy
An endoscopy is a procedure used in medicine to look inside the body. The endoscopy procedure uses an endoscope to examine the interior of a hollow organ or cavity of the body. Unlike many other medical imaging techniques, endoscopes are insert ...

In medical and healthcare professional education
Most health profession schools, such as medical,
physician assistant, and dental schools, require that students complete a practical (dissection) course in gross human anatomy. Such courses aim to educate students in advanced funadmental human anatomy and seek to establish anatomical landmarks used to aid
medical diagnosis. Most schools provide students with
cadavers for investigation by dissection, aided by dissection manuals, as well as cadaveric atlases (e.g.
Netter's,
Rohen's).
Working intimately with a cadaver during a gross anatomy course has been shown to capture the essence of the patient-provider relationship. However, the expense of maintaining cadaveric dissection facilities has limited the time and resources available for gross anatomy teaching in medical schools that are less funded, with some adopting alternative prosection-based or simulated teaching. This, coupled with decreasing time dedicated to gross anatomical courses within the growing greater medical school curriculum, has caused controversy surrounding the sufficiency of anatomical teaching with nearly half of newly qualified doctors believing they received insufficient anatomy teaching due to the course often being condensed into one semester.
Medical schools have implemented on-screen anatomical lessons and tutorials to teach students surgical procedures. The use of technological visual aids accompanied with gross dissection have been shown to be more effective than learning via one modality alone. Online and physically made flashcards and quizzes
have been long used.
