Human Eye
The human eye is one of the most complex parts of
our physiology. Our eyes can differentiate between
approximately 10 million different colors and can even
detect a single photon of light. In the eye, light travels
through the cornea and pupil to the crystalline lens,
which focuses the light onto the retina. The light falling
onto the retina is converted to electrical signals that
travel through the optic nerve to the brain, creating
what we experience as vision. Image Credit: Dhyamis

Tissue with Bronchogenic Carcinoma
Tissue is an extracellular matrix of similar cells from the
same origin that together carry out a specific function.
Most cancers arise in epithelial tissue. One such example
is Bronchogenic Carcinoma, a lung cancer that begins in
the tissue lining the airway of the lungs and spreads outwards,
creating more and more mutated cells, eventually
forming a tumor. Lung and bronchus cancers account
for about 13 percent of new cancer cases in the United
States. Image Credit: Microscopy U.

Fluorescence Image of Neuronal Culture
The cell is the basis for all life on Earth. From the 30
meter long Blue Whale to the 370 nanometer long Pelagibacter
ubique, every living organism on the planet
consists of at least one cell. Every individual cell consists
of genetic material suspended in a cytoplasm contained
within a membrane. The human body is made of about
37.2 trillion cells. Image Credit: Jan Schmoranzer, 2011
