Embedding in Histopathology: Embedding is the process in which the tissues or the specimens are enclosed in a mass of the embedding medium using a mould. Since the tissue blocks are very thin in thickness they need a supporting medium in which the tissue blocks are embedded. This supporting medium is called embedding medium. Various…
Tissue Processing for histopathology: Tissue processing is a critical step in histopathology, transforming biological tissue into a form suitable for microscopic examination. This involves a series of steps that preserve tissue structure and prepare it for sectioning and staining. What is tissue processing? The technique of getting fixed tissues into paraffin is called tissue processing….
Fixation: In the fields of histology, pathology, and cell biology, fixation is a critical step in the preparation of histological sections by which biological tissues are preserved from decay, thereby preventing autolysis or putrefaction. Fixation Definition: It is a complex series of chemical events which brings about changes in the various chemical constituents of cell…
Importance of Zoology: Zoology is the scientific study of animals. It encompasses a vast array of topics, from the anatomy and physiology of individual creatures to the behavior and ecology of entire populations. Zoologists explore the diversity of animal life, from microscopic invertebrates to gigantic mammals, examining their structures, functions, classifications, habits, and interactions with…
Collection and Selection of Specimens or Tissue for Whole Mount: The accurate and precise collection and selection of specimens or tissues are paramount in the field of microscopy and pathology. These initial steps significantly impact the subsequent analysis and interpretation of results. This article will delve into the critical aspects of specimen collection and selection…

Hemichordata: They are tongue worms, which have been included for long as a subphylum or class of Phylum Chordata in the lower chordates or Protochordata, but now they are placed as an independent phylum of invertebrates, since their supposed affinities with chordates are doubtful. Hemichordata are a small group of marine, solitary or colonial, worm-like,…
