What are the external parts? Your penis and scrotum are the two parts of the male (or what’s typically called male) external sex anatomy (outside your body). Your penis is made of 3 layers of spongy tissue. When you get turned on, blood fills these tissues. This makes your penis get harder and stand up, which is also called getting an erection or hard-on. The average size of an adult erect (hard) penis is 5 to 7 inches long. The size of your penis when it’s flaccid (soft) doesn’t have much to do with its size when it’s hard. Some penises get much bigger when they get hard. Others ...

Anatomy is the oldest scientific discipline of medicine. The first documented scientific dissections on the human body are carried out as early as the third century B.C. in Alexandria. At that time, anatomists explore anatomy through dissections of animals, primarily pigs and monkeys. Claudius Galen (129-199) is the most prominent physician in Ancient Greece whose conclusions are purely based on the study of animals and whose faulty theories on human anatomy dominate and influence the medical science until the Renaissance, i.e. for over 1,000 years. Although anatomy is not officially banned by the Church, social authorities reject the dissection of human corpses until the 12th and even 13th century. This is why anatomical research stagnates. A change in attitude towards the teaching anatomy only happens during the 13th and 14th century. However, teaching consists primarily of lectures from the canonical works of Galen—without verification through actual dissections. In medieval times, the body is seen as the frail housing of the soul. During the Renaissance, however, the human body is exalted for its beauty, and becomes the primary source of inspiration for artists of this epoch. For the sake of art, many Renaissance artists begin studying the human body. Leonardo da Vinci and Michelangelo do not only attend dissections performed by their medically trained friends, but rather pick up the scalpel themselves – with the aim to illustrate the body in all its natural splendor. ...

Human Body About Human Body If we were to “break apart” the human body at the microscopic level, then the cell would constitute its most basic unit. The average adult has somewhere between 30 – 40 trillion cells, and an estimated 242 billion new cells are produced every day. When a select group of cells with similar functions come together, it forms a tissue. Tissues cumulate into organs, group of organs form organ systems and eventually, a complete organism. Cells -> Tissues -> Organs -> Organ System -> Organism • • • • • • • • Human Anatomy Skeleton The human body exhibits a variety of movements from walking and running to crawling, jumping and climbing. The framework that enables us to do all these activities is the skeleton. Humans have as much as 300 bones at birth. However, the bones start to fuse with age. At adulthood, the total number of bones is reduced to 206. Human Anatomy is the scientific study of form and shapes of human beings The skeleton also protects several vital organs such as the heart, lungs and the liver. Bones are attached to other bones through ligaments, a fibrous connective tissue. Joints are the points at which two or more bones meet. They enable a range of movements like rotation, abduction, adduction, protraction, retraction and more. Based on flexibility and mobility, joints can be further classified into movable joints and immovable joints. Movable joints are flexible while immovable joints (also called fixed joints) are non-flexible ...

41 Questions from Britannica’s Most Popular World History Quizzes Politics). These are the only Hippocrates’ reputation, and Corpus Hippocraticum). Linguists and physicians subsequently wrote commentaries on them, and, as a result, all the virtues of the Classical medical works were eventually The virtues of the Hippocratic writings are many, and, although they are of varying lengths and literary quality, they are all simple and direct, earnest in their desire to help, and lacking in technical jargon and elaborate argument. The works show such different views and styles that they cannot be by one person, and some were clearly written in later periods. Yet all the works of the Corpus share basic assumptions about how the body works and what disease is, providing a sense of the substance and appeal of ancient Greek medicine as practiced by Hippocrates and other physicians of his era. Prominent among these attractive works are the Epidemics, which give annual records of weather and associated diseases, along with individual case histories and records of treatment, collected from cities in northern Greece. Diseases deal with serious illnesses, proceeding from the head to the feet, giving symptoms, prognoses, and treatments. There are works on diseases of women, childbirth, and pediatrics. Prescribed medications, other than foods and local salves, are generally purgatives to rid the body of the noxious substances thought to cause disease. Some works argue that medicine is indee...

Tomorrow is the birthday of Albrecht von Haller, the father of experimental physiology. Haller, a Swiss biologist born in 1708, worked as a professor in Bern and Göttingen. He undertook myriad experiments, which he collected in his 1747 book First Lines in Physiology and a landmark eight-volume treatise, Physiological Elements of the Human Body, published between 1757 and 1766. Haller discovered that some tissues react to stimuli, a phenomenon he divided into "irritability" (for muscles) and "sensibility" (for nerves). In his last years, he catalogued 52,000 publications about anatomy, botany, surgery, and medicine in a 20-volume bibliography. He died in December 1777.
