    Study Notes

    Vertebral Column of Toad

    • Vertebrae are procoelous, meaning the concave surface faces anteriorly

    Humerus of Toad

    • The head of the humerus is spherical, distinct from other vertebrates

    Glomerulus of Bufo Kidney

    • The glomerulus appears spherical in cross-section

    Spinal Cord of a Rabbit

    • T.S. (transverse section) shows a central canal surrounded by grey matter and a peripheral region of white matter.
    • The grey matter contains nerve cell bodies and dendrites.
    • The white matter contains myelinated nerve fibers.

    Pancreas of a Rat

    • Shows cells arranged in islets of Langerhans, appearing as irregular clusters

    Areolar Connective Tissue

    • Loosely arranged fibers and cells, including fibroblasts, mast cells, and macrophages

    Mucous Connective Tissue

    • Abundant ground substance with a few cells and fibers, often found in umbilical cord

    Dense Bone

    • Concentric lamellae and central canal, arranged as osteons

    Trachea of Rabbit with Hyaline Cartilage

    • Presence of rings of hyaline cartilage around the trachea

    Importance of Tissue Identification

    • Proper diagnosis and treatment of diseases
    • Understanding the structure and function of organs
    • Researching the development and regeneration of tissues
