The part of the body that controls all voluntary and involuntary functions and all sensory functions.
BRAIN
The lining of cells at the back of the eye. This senses the light reflected from an object and sends nerve signals to the brain.
RETINA
When light bounces off an object
REFLECTION
A lens that is curved outward. It is wider in the middle.
A small, thin sample that is observed through the microscope.
SPECIMEN
The outer layer of the eye, which helps focus light
CORNEA
The muscular structure that opens and closes the pupil.
IRIS
When lights passes through a transparent object's and is bent or redirected in a different direction.
REFRACTION OR REFRACT
A lens that is curved INWARD. It is thinner in the middle than at either end.
CONCAVE lens
IMAGE
The organ that contains all structures needed for sight.
EYE
The nerve that carries information from the eye to the brain.
OPTIC NERVE
The process that makes fine details more visible.
RESOLUTION
A scientific tool that is used to view very small objects that are too small to see using the naked eye or a hand lens
MICROSCOPE
EYEPIECE
A curved piece of transparent material, usually glass or plastic that refracts light. A lens is also found in the human eye. Another definition for this is a transparent (see-through) solid object through which light can be refracted.
LENS
A magnifying lens that aids in seeing small objects.
Hand Lens
The portion of an object that is visible through a hand lens or other viewing device.
FIELD OF VIEW
The science of observing very small (microscopic) objects and small details.
MICROSCOPY
Calculated by dividing the image size by the object size.
POWER OF MAGNIFICATION
An opening in the eye that allows light to enter and be detected.
PUPIL
When a lens refracts light and increases the size of an object's image.
MAGNIFY
When a lens refracts light and increases the size of an objects image
MAGNIFY
A piece of glass that holds a specimen.
SLIDE
Calculated by multiplying the power of the microscope's eyepiece (10X) and the power of the objective used to view the specimen (either 4X, 10X, or 40X)
