Functional Features

Clear and dark satellite cell classes were identified by electron microscopy in the lumbar sensory ganglia of domestic fowl in 8 pre and 4 post-hatching stages of development. Some cytologic differences found between the two classes relating to the rough-endoplasmic reticulum, ribosomes, Golgi apparatus and junctional complexes suggest the existence of distinct functional features for both types of satellite cells.

Ca Ions

Increases in intracellular Ca ions follow each cycle of nerve cell activity. Sources of Ca are voltage- and receptor-operated membrane ion channels and endoplasmic reticulum (ER). Ca release from ER can be triggered by different second messengers, and uptake into the ER can terminate the Ca signal.
