Let’s Look at Slides #4 (last part)
Last part of the microscope series! Let’s go!

59. Rabbit Hyaline Cartilage:
There are three varieties of cartilage, hyaline, elastic, and fibrocartilage. The most abundant type is hyaline, found as supportive tissues in the nose, ears, trachea, larynx, and smaller respiratory tubes. As articular cartilage, hyaline is found covering the articular surfaces of bones in synovial joints.
60. Rabbit Lymph Node (sec.):
Lymph nodes are small, bean-shaped glands throughout the body. They are part of the lymph system, which carries fluid (lymph fluid), nutrients, and waste material between the body tissues and the bloodstream. The lymph system is an important part of the immune system, the body’s defense system against disease.
61. Rabbit Spinal Cord (c.s.):
The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS). In the human, the spinal cord begins at the occipital bone where it passes through the foramen magnum and meets and enters the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. Also, the spinal cord has a varying width, ranging from 13 mm (1⁄2 in) thick in the cervical and lumbar regions to 6.4 mm (1⁄4 in) thick in the thoracic area.
62. Rhizopus (w.m.):
Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. They are found on a wide variety of organic substrates, including “mature fruits and vegetables”, jellies, syrups, leather, bread, peanuts, and tobacco. Some Rhizopus stolonifer species are opportunistic agents of human zygomycosis (fungal infection) and can be fatal. Rhizopus infections may also be a complication of diabetic ketoacidosis. This widespread genus includes at least eight species.
63. Rice Stem (c.s.):
64. Root-Meristem (l.s.):
A meristem is a tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place.
65. Spirillum smear:
Spirillum is a genus of Gram-negative bacteria within family Spirillaceae. There are two species in Spirillum with standing in nomenclature, Spirillum winogradskyi and Spirillum volutans. The taxonomic position of three other species provisionally bearing the Spirillum genus name (Spirillum minus, Spirillum pleomorphum, and Spirillum pulli) is uncertain and these have no standing in nomenclature.
The bacteria is back.
66. Spirogyra Conjugation (w.m.):
Spirogyra (common names include water silk, mermaid’s tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is diagnostic of the genus. It is commonly found in freshwater areas, and there are more than 400 species of Spirogyra in the world. Spirogyrameasures approximately 10 to 100 μm in width and may grow to several centimeters in length. It is also a microorganism.
That’s all. We did 66 slides and didn’t do 34. To see what we missed click on the link:
The link has all of the slides. And you could zoom in and out between 80x-0.45x. You should go over there if you’re interested in biology and slide specimens. But the problem is that they don’t explain what the specimens are. If you want to know, go back to the previous posts.

I hope you enjoyed the series. It took me 2 hours to do one part!
