As optometrists‚ we always seek ways to improve primary eye care provisions to our patients. Primary eye care encompass from refractive services to the diagnosis and management of ocular pathologies. With the steadily evolving field of technology‚ eye care services are more fine tuned and this enable optometrists and other eye care practitioners to provide even better eye health services to patients. Though not many independent optometrists have the luxury of having some of the costly technology

during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory states that new cells are formed from pre-existing cells‚ and that the cell is a fundamental unit of structure‚ function and organization in all living organisms. It is one of the foundations of biology. History: The cell was discovered by Robert Hooke in 1665. He examined (under a coarse‚ compound microscope) very thin slices of cork and saw a multitude of tiny pores

The discipline of archaeology is by no means a simple nor singular study of the past. Due to the wide range of evidence within the archaeological record‚ from organic to inorganic‚ many different methods and approaches are taken in order to deal with the wide spectrum of differing evidence. Nevertheless‚ the study of pottery is without doubt one of the most important tasks taken on by any archaeologist. A great wealth of information can be gained from the study of pottery‚ despite its inanimate state

All information both to and from the body must be coordinated and transmitted simultaneously and very quickly. The brain itself requires extremely fast speeds to operate at even at the simplest level. How do the biological tissues of our body support such rapid coordination of the brain‚ limbs‚ and sensory input? They do so with nervous system tissue that imitates electrical wiring. A series of photomicrographs and schematic illustrations show myelinated nerve fibers. Panel A is an illustration

growth. There was a correlation observed between the concentration of lead the pollen was exposed to and the extent of growth inhibition observed. The effect of 20 ppm‚ 40ppm‚ 60ppm and 80 ppm lead on pollen tube germination were studied using light microscopy. A progressive decrease in the percentage of pollen germination indicated that higher levels of toxicity caused higher growth inhibitions. Introduction: Heavy metals are natural components of the Earth’s crust. They cannot be degraded or
