• Ophthalmologic Examination
  Of all the organs of the body, the eye is most accessible to direct examination. Visual function can be quanti¬fied by simple subjective testing. The external anatomy of the eye is visible to inspection with the unaided eye and with fairly simple instruments and can be projected with the use of a teaching microscope. Even the interior of the eye is visible through the clear cornea. The eye is the only part of the body where blood vessels and cen¬tral nervous system tissue (retina and optic nerve) can be viewed directly. Important systemic effects of infec¬tious, autoimmune, neoplastic, and vascular diseases may be visible from the internal eye examination. The functions and characteristics of each part can be taught in a classroom or a group with the use of a teaching microscope. A teaching microscope is a great tool in imparting information about the eye to a large audience. read more...


• Cranial Nerves Affecting The Eye
  The oculomotor nerve leaves the brainstem between the cerebral peduncles and passes near the posterior com¬municating artery of the circle of Willis. Lateral to the pituitary gland, it is closely approximated to the optic tract, and here it pierces the dura to course in the lateral wall of the cavernous sinus, as seen in a teaching microscope. As the nerve leaves the cav¬ernous sinus, it divides into superior and inferior divi¬sions. The superior division enters the orbit within the annulus of Zinn at its highest point and adjacent to the trochlear nerve. read more...


• The Conjunctiva, Tenon’s Capsule, The Sclera And Episclera
  A teaching microscope aids in the large scale viewing of the different eye parts. The conjunctiva, when examined and viwed with the use of a teaching microscope, is the thin, transparent mucous mem¬brane that covers the posterior surface of the lids (the palpebral conjunctiva) and the anterior surface of the sclera (the bulbar conjunctiva). It is continuous with the skin at the lid margin (a mucocutaneous junction) and with the corneal epithelium at the limbus. The palpebral conjunctiva lines the posterior sur¬face of the lids and is firmly attached to the tarsus. At the superior and inferior margins of the tarsus, the con¬junctiva is reflected posteriorly (at the superior and in¬ferior fornices) and covers the episcleral tissue to be¬come the bulbar conjunctiva. read more...


• The Lens, Aqueous, And The Anterior Chamber Angle Of The Eye
  The eye has many components. Among its parts are the lens, aqueous humor and the anterior chamber angle of the eye. The properties and characteristics of each parts can be viewed in a large scale using a teaching microscope. read more...


• Growth & Development Of The Eye
  A teaching microscope provides teachers another way of presenting their lessons. A teaching microscope can be attached to a computer or a large screen in order for students to see the specimen being studied. The growth and development of the eye can be explained to the class in a visual way using a teaching microscope. read more...


• Microbiology Microscopy Techniques
  Teaching your kids or supplementing what they learn from school about microbiology and to an extent, microscopy techniques, can be made easier and more fun if you’re working with an actual teaching microscope. A good teaching microscope is one with at least dual view eyepiece holes so that you and your child can view and analyze specimens together. read more...


• Microscopes for Teachers
  Teaching microscopes today may be purchased for less than $200 while high-end models can go as far as a little over $2,000. But price nowadays may not have anything to do with quality and everything to do with the range of features it offers. In most cases, the costs of teaching microscopes used in educational institutions are not a problem for the teacher. But if you are looking for a teaching microscope you can use at home for teaching after-school lessons or tutoring, choose a teaching microscope that befits the needs of your lesson. read more...


• Various Tips on Selecting Teaching Microscope
  Want to know the better way to teach science subjects? Let the students see and feel the subjects for themselves! Biology subject will never be the same again if students will be having their sample viewing through the microscope. The simple leaves or insects will be much appreciated if components and cells are viewed upon. As a teacher, this microscopy process of learning can be an edge, thus, selecting the right teaching microscope is very important.read more...


• Teaching the Important Uses of the Electron Microscope
  Unlike conventional microscopy, the electron microscope can provide excellent images in very high magnifications. Usually, the problem with traditional light microscopy is that the images produced are not very effective for proper observation or inspection. Since it was first introduced in the 30s, the electron microscope has allowed scientists, explorers and researchers to view a specimen’s surface and structure at microscopic levels. The electron microscope is also one of the best and most effective tools to use for teaching.read more...


• Types of Teaching Microscopes Used in the Classroom Setting
  Many of the most important discoveries and inventions that appeared during the last two hundred years came as a result of the microscope. From the discovery of new vaccines to the improvement of materials to the development of better drugs and stronger species of plants and animals, the microscope was a contributory factor. This is why a good variety of optical microscopy are being used as teaching microscopes, either to introduce students to a certain study or enhance their knowledge regarding a particular subject. The most common types of teaching microscopes include:read more...


• The Phytohaemagglutinin
  The compound haemagglutinin or lectin has been utilized for years by the immunologists with the help of microscopy using some microscopes to activate DNA fusion in T lymphocytes, and lately to stimulate suppressed human immunodeficiency virus type 1 or HIV-1, AIDS virus from human marginal lymphocytes.read more...


• Thrombocytes or Blood Platelets
  The thrombocytes commonly known as the blood platelets do not have nucleus as observed by means of microscopy using a microscope like the teaching-microscope. The blood platelets of mammals were never nucleated cells, not like the erythrocytes that are also absent of nucleus. Thrombocytes are actually the remains of the cytoplasm of extremely huge thrombocyte precursor cells called as the megakaryocytes.read more...


• Non-Granular Leukocytes
  The leukocytes or the white blood cells can either be granular or non-granular. The monocytes and lymphocytes are classified under the non-granular leukocytes. The monocytes can be somewhat bigger than granulocytes having diameter of approximately twelve to eighteen micrometers as seen under the microscope like a teaching-microscope. Their cytoplasm does not have any structures that can be apparent in a microscope with the use of conventional stains, nevertheless their stains are commonly stronger as compared with the granulocytes.read more...


• Granular Leukocytes
  One of the components of blood is the white blood cells or leukocytes. Leukocytes may be with or without granules as seen by means of microscopy under the teaching-microscope. Approximately twelve to fifteen micrometers in diameters as observed using a microscope such as teaching-microscope are the sizes of the granular leukocytes. Lobes are formed from nuclei and nucleoli are invisible. The quantity of the nuclear lobes differs based on the cell type as examined via microscopy under the teaching-microscope. Each and every kind of granulocytes is motile.read more...


• Cryptosporidiosis
  Cryptosporidium parvum happens to be a member of the bigger group of parasites that are communally known as coccidia. It can contaminate mammals, birds, fish and reptiles. It is actually a protozoan parasite as observed under the microscope even on a teaching-microscope. Once the public water supply has become infected by Cryptosporidium, epidemics of cryptosporidiosis can take place. The parasite is also one of the common causes of human diarrheas based on the stools examined using the microscopes such as teaching-microscope.read more...
