Compare and contrast the structure and function of plasma cells, macrophages and cardiomyocytes
Plasma Cell
Macrophages
Cardiomyocyte
Precursor cells produced in the Bone Marrow (Lymphoid progenitor)
"Clockface", eccentric nucleus
Basophilic cytoplasm
Extensively-developed Golgi apparatus and RER
Suitable for high Ig production
Specificity to a single antigen
B-cell lymphocytes differentiation
WBC (Agranulocyte)
Phagocytosis
Immunity
Innate
Adaptive
Antigen-presenting cell
Precursor cell produced in the Bone Marrow (Myeloid progenitor)
Many lysosomes and phagosomes
Monocyte differentiation
Well-developed cytoskeleton
Pseudopodia and migration
Heart muscle cell
Many mitochondria
High need for energy
Sarcomere - Actin/Myosin II system
Wide cytoplasm compared to nucleus extension
Cardiac systole/diastole
Neuromuscular junction - connection with nervous fibers
Sarcoplasmic Reticulum
Characteristic structure of Plasma Memb. (T tubules)
Use of Ca2+
