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…
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….

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…
Taenia solium: Taenia solium, commonly known as the pork tapeworm, is a parasitic flatworm that infects both humans and pigs. Understanding its morphology is crucial not only for the identification and diagnosis of infections but also for developing effective treatments and preventive measures. This article delves into the detailed morphological features of Taenia solium. Its…
Fasciola hepatica: Fasciola, often known as the common fluke, is a parasitic flatworm that lives in the liver and bile passages of vertebrates, including dogs, pigs, sheep, cattle, and rabbits. Fasciola hepatica An illness known as fascioliasis, or liver rot, is brought on by the several species of Fasciola, such as F. hepatica, the liver…
Reproduction in Paramoecium: Paramecium reproduces asexually by transverse binary fission and also undergoes several types of nuclear reorganisation, such as conjugation, endomixis, autogamy, cytogamy and hemixis, etc. Asexual Reproduction in Paramoecium Asexual reproduction is the more common mode of reproduction in protozoa. It allows for rapid population growth under favorable conditions. There are several forms…
