Sectioning of Tissue: It is a critical step in various scientific and medical fields, particularly histology, pathology, and microscopy. Sectioning of tissue or Section cutting Defects, Causes and Remedies Histologists are confronted often with difficult tissue blocks that will not section easily, for example, brittle or shrunken tissue, improperly infiltrated tissues, or sections with, holes … Read more
Rotary and Rocking Microtome: Microtomes are essential tools in the field of histology, allowing to thin tissue sections for microscopic analysis. Most commonly used microtome are the rotary and rocking microtomes. Understanding their uses, handling methods, and precautions is crucial for producing accurate results in both medical and scientific research. Rotary and Rocking Microtome Rotary … Read more
Biological Significance of Some Invertebrate Animals: Some of the important invertebrate animals and their biological significance are studied in this article. Biological Significance of Some Invertebrate Animals 1. Obelia 2. Physalia 3. Corals 4. Pearl Oyester 5. Bipinnaria larvae
Nephridia: Nephridia are excretory organs found in many invertebrates, such as annelids (e.g., earthworms), mollusks, and some arthropods. Nephridia are excretory organs found in many invertebrates, such as annelids (earthworms), mollusks, and some arthropods. They play a role similar to kidneys in vertebrates, helping to remove metabolic waste from the organism’s body. The basic function of … Read more
Coelomate Animals: Here we can study the museum specimens of celomate animals their classification and characteristic. Coelomate animals are those that possess a true coelom, a fluid-filled body cavity completely lined by mesodermal tissue. This group includes a wide variety of animals, from simple invertebrates (Mollusks, Annelids, Arthropods and Echniodermata) to complex vertebrate (Chordata) animals. … Read more

Microtechniques: Microtechniques are specialized methods used to prepare biological samples for microscopic examination. These techniques involve a series of steps that preserve the structure of the sample, allow for thin sectioning, and stain specific components for better visualization under a microscope. Rat is dissected and Ovary/Testis, Intestine or kidney is taken out and fixed in … Read more
