Anatomy is the study of the structure of the human body.
Comparative anatomy compares the structure of our bodies to those of animals’ bodies.
The first great anatomist was the ancient Roman physician, Galen (AD 129-199).
The first great book 23- of anatomy was written in 1543 by the Flemish scientist Andreas Vesalius (1514-1564). It is called De Humani Corporis Fabrica (`On the Fabric of the Human Body.’)
To describe the location of body parts, anatomists divide the body into quarters.
The anatomical position is the way the body is positioned to describe anatomical terms — upright, with the arms hanging down by the sides, and the eyes, palms and toes facing forwards. 386
The central coronal plane divides the body into front and back halves. Coronal planes are any slice across the body from side to side, parallel to the central coronal plane.
The ventral or anterior is the front half of the body.
The dorsal or posterior is the back half of the body.
Every part of the body has a Latin name, but anatomists use a simple English name if there is one. Health and disease
Much of our basic knowledge of human anatomy comes from the anatomists al the 16th and 17th centuries, who meticulously cut up corpses and then thtunitely drew what they saw.
Your body systems are interlinked – each has its own task, but they are all dependent on one another.
The skeleton supports the body, protects the major organs, and provides an anchor for the muscles.
The nervous system is the brain and the nerves – the body’s control and communications network.
The digestive system breaks down food into chemicals that the body can use to its advantage.
The immune system is the body’s defence against germs. It includes white blood cells, antibodies and the lymphatic system.
The urinary system controls the body’s water balance, removing extra water as urine and getting rid of impurities in the blood.
The respiratory system takes air into the lungs to supply oxygen, and lets out waste carbon dioxide.
The reproductive system is the smallest of all the systems. It is basically the sexual organs that enable people to have children. It is the only system that is different in men and women.
The other body systems are the hormonal system (controls growth and internal co-ordination by chemical hormones), integumentary system (skin, hair and nails), and the sensory system (eyes, ears, nose, tongue, skin, balance).
