The history of medicine is both a study of medicine throughout history as well as a multidisciplinary field of study that seeks to explore and understand medical practices, both past and present, throughout human societies.
Veterinary medicine is the branch of medicine that deals with the prevention, management, diagnosis, and treatment of disease, disorder, and injury in non-human animals. The scope of veterinary medicine is wide, covering all animal species, both domesticated and wild, with a wide range of conditions that can affect different species.
The history of anatomy extends from the earliest examinations of sacrificial victims to the sophisticated analyses of the body performed by modern anatomists and scientists. Written descriptions of human organs and parts can be traced back thousands of years to ancient Egyptian papyri, where attention to the body was necessitated by their highly elaborate burial practices.
The hymen is a thin piece of mucosal tissue that surrounds or partially covers the vaginal opening. A small percentage are born with hymens that are imperforate and completely obstruct the vaginal canal. It forms part of the vulva and is similar in structure to the vagina. The term comes straight from the Greek, for 'membrane'.
Neuroanatomy is the study of the structure and organization of the nervous system. In contrast to animals with radial symmetry, whose nervous system consists of a distributed network of cells, animals with bilateral symmetry have segregated, defined nervous systems. Their neuroanatomy is therefore better understood. In vertebrates, the nervous system is segregated into the internal structure of the brain and spinal cord and the series of nerves that connect the CNS to the rest of the body. Breaking down and identifying specific parts of the nervous system has been crucial for figuring out how it operates. For example, much of what neuroscientists have learned comes from observing how damage or "lesions" to specific brain areas affects behavior or other neural functions.
The Ebers Papyrus, also known as Papyrus Ebers, is an Egyptian medical papyrus of herbal knowledge dating to c. 1550 BCE. Among the oldest and most important medical papyri of Ancient Egypt, it was purchased at Luxor in the winter of 1873–1874 by the German Egyptologist Georg Ebers. It is currently kept at the Leipzig University Library in Germany.
Neurophysiology is a branch of physiology and neuroscience that studies nervous system function rather than nervous system architecture. This area aids in the diagnosis and monitoring of neurological diseases. Historically, it has been dominated by electrophysiology—the electrical recording of neural activity ranging from the molar to the cellular, such as patch clamp, voltage clamp, extracellular single-unit recording and recording of local field potentials. However, since the neuron is an electrochemical machine, it is difficult to isolate electrical events from the metabolic and molecular processes that cause them. Thus, neurophysiologists currently utilise tools from chemistry, physics, and molecular biology to examine brain activity.
Chinese herbology is the theory of traditional Chinese herbal therapy, which accounts for the majority of treatments in traditional Chinese medicine (TCM). A Nature editorial described TCM as "fraught with pseudoscience", and said that the most obvious reason why it has not delivered many cures is that the majority of its treatments have no logical mechanism of action.
The BMJ is a weekly peer-reviewed medical journal, published by BMJ Group, which in turn is wholly-owned by the British Medical Association (BMA). The BMJ has editorial freedom from the BMA. It is one of the world's oldest general medical journals. Previously called the British Medical Journal, the title was officially shortened to BMJ in 1988, and then changed to The BMJ in 2014. The journal is published by BMJ Publishing Group Ltd, a subsidiary of the British Medical Association (BMA). The current editor-in-chief of The BMJ is Kamran Abbasi, who was appointed in January 2022.
The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs. In the lungs the blood is oxygenated and returned to the left atrium to complete the circuit.
The Edwin Smith Papyrus is an ancient Egyptian medical text, named after Edwin Smith who bought it in 1862, and the oldest known surgical treatise on trauma. From a cited quotation in another text, it may have been known to ancient surgeons as the "Secret Book of the Physician".
The rectouterine pouch is the extension of the peritoneum into the space between the posterior wall of the uterus and the rectum in the human female.
The sympathetic trunks are a paired bundle of nerve fibers that run from the base of the skull to the coccyx. They are a major component of the sympathetic nervous system.
Medical literature is the scientific literature of medicine: articles in journals and texts in books devoted to the field of medicine. Many references to the medical literature include the health care literature generally, including that of dentistry, veterinary medicine, pharmacy, nursing, and the allied health professions.
The Charaka Samhita is a Sanskrit text on Ayurveda. Along with the Sushruta Samhita, it is one of the two foundational texts of this field that have survived from ancient India. It is one of the three works that constitute the Brhat Trayi.
The Sushruta Samhita is an ancient Sanskrit text on medicine and surgery, and one of the most important such treatises on this subject to survive from the ancient world. The Compendium of Suśruta is one of the foundational texts of Ayurveda, alongside the Charaka-Saṃhitā, the Bhela-Saṃhitā, and the medical portions of the Bower Manuscript. It is one of the two foundational Hindu texts on the medical profession that have survived from ancient India.
Sushruta is the listed author of the Sushruta Samhita, a treatise considered to be one of the most important surviving ancient treatises on medicine and is considered a foundational text of Ayurveda. The treatise addresses all aspects of general medicine, but the impressive chapters on surgery have led to the false impression that this is its main topic. The translator G. D. Singhal dubbed Suśruta "the father of plastic surgery" on account of these detailed accounts of surgery.
Egyptian medical papyri are ancient Egyptian texts written on papyrus which permit a glimpse at medical procedures and practices in ancient Egypt. These papyri give details on disease, diagnosis, and remedies of disease, which include herbal remedies, surgery, and magical incantations. Many of these papyri have been lost due to grave robbery. The largest study of the medical papyri to date has been undertaken by Humboldt University of Berlin and was titled Medizin der alten Ägypter.
Gaya Prasad Pal is an Indian anatomist, professor and the director of Modern Institute of Medical Sciences, Indore. An elected fellow of the National Academy of Medical Sciences, Indian Academy of Sciences and National Academy of Sciences, India, Pal is known for his researches on biomechanics and load transmission of human spinal column. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards for his contributions to Medical Sciences in 1993.
Vaginal rugae are structures of the vagina that are transverse ridges formed out of the supporting tissues and vaginal epithelium in females. Some conditions can cause the disappearance of vaginal rugae and are usually associated with childbirth and prolapse of pelvic structures. The rugae contribute to the resiliency and elasticity of the vagina and its ability to distend and return to its previous state. These structures not only allow expansions and an increase in surface area of the vaginal epithelium, they provide the space necessary for the vaginal microbiota. The shape and structure of the rugae are supported and maintained by the lamina propria of the vagina and the anterior and posterior rugae.
