anatomy science that studies the form and composition of the body’s structures gross anatomy study of the larger structures of the body, typically with the unaided eye; also referred to macroscopic anatomy homeostasis steady state of body systems that living organisms maintain microscopic anatomy study of very small structures of the body using magnification physiology science that studies the chemistry, biochemistry, and physics of the body’s functions regional anatomy study of the structures that contribute to specific body regions systemic anatomy study of the structures that contribute to specific body systems Human anatomy is the scientific study of the body’s structures. Some of these structures are very small and can only be observed and analysed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word “anatomy” comes from a Greek root that means “to cut apart.”...

A digital single-lens reflex camera, or DSLR, is a combination of two different camera technologies. First, the single-lens reflex technology determines how the shutter operates to allow light through the lens and onto the sensor. Second, the digital aspect of the camera means that the camera uses a digital sensor to capture the image instead of a piece of film. Like all cameras, a DSLR works by manipulating light. When light bounces off the subject and makes its way to the observer, where the camera is located, if the light passes through a small enough opening it can create an image on the other side of the opening. By using a lens, positioned in front of the opening, the camera operator can bring that image into focus at a given distance behind the opening, which is where the DSLR's digital image censor is located. The SLR aspect of the DSLR solves an old camera problem where the photographer's view of the subject was not the same as the camera's. ...

Light rays enter the eye through the cornea, the clear front “window” of the eye. The cornea’s refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the centre of the iris through which light enters the eye.  The iris works like a shutter in a camera. It’s got the ability to enlarge and shrink, depending on how much light is entering the eye. After passing through the iris, the light rays pass thru the eye’s natural crystalline lens. This clear, flexible structure works like the lens in a camera, shortening and lengthening its width in order to focus light rays properly. Light rays pass through a dense, transparent gel-like substance, called the vitreous that fills the globe of the eyeball and helps the eye hold its spherical shape. In a normal eye, the light rays come to a sharp focusing point on the retina. The retina functions much like the film in a camera. It is responsible for capturing all the light rays, p...

Clinical photography (anatomy & physiology) Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science which deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated over immediate and long timescales. Anatomy and physiology, which study the structure and function of organisms and their parts, make a natural pair of related disciplines, and they are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine Anatomy is the study of the structure and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. Some specializations within each of these s...
