Fixation, dehydration, clearing, embedding, and sectioning, followed by staining for microscopic visualization.
Hematoxylin and eosin (H&E) stain, where hematoxylin stains nuclei blue and eosin stains cytoplasm pink.
Transmission electron microscopy (TEM) for internal cell detail and scanning electron microscopy (SEM) for surface topography.
Osteoclasts are multinucleated cells that resorb bone matrix by secreting acids and proteolytic enzymes.
Skeletal muscle shows long, non-branching fibers with multiple peripheral nuclei; cardiac muscle shows branching fibers with single central nuclei.
Thymus, which provides a specialized microenvironment for T-cell education and maturation.
Nephron, consisting of the renal corpuscle (filtration) and renal tubule (reabsorption and secretion).
Hyaline cartilage (type II collagen), elastic cartilage (elastic fibers), and fibrocartilage (type I collagen).
Beta cells (insulin), alpha cells (glucagon), delta cells (somatostatin), and PP cells (pancreatic polypeptide).
Lymph nodes filter lymph via sinuses; spleen filters blood, with white pulp as lymphoid sheath around central arterioles.
