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+
