Free ribosomes (polysomes or polyribosomes
• Inclusions- Generally temporary component of the cell
- Appear as vacuoles, granules, globules
- Accumulation of metabolites or cell products
- Stored food – CHO, CHON, fats
- Crystals
- Pigments
- Secretory granules

• PLASMA CELLS - Ovoid cells with eccentric nucleus, intensely basophilic, chromatin is dark-staining and regularly arranged “cartwheel” or “spokeswheel” appearance
• Large ovoid cells, cytoplasm has abundant basophilic granules, nucleus is centrally located
• Granules contain heparin (anticoagulant), histamines (increases vascular permeability, vasodilation)
• Anaphylactic reactions
