Parvalbumin Distribution in the Musculature of the Pharyngo-oesophageal Segment

The composition and size of muscle fibre types in the hyopharyngeus (HP), thyropharyngeus (TP), cricopharyngeus (CP) and cervical oesophageal muscle (CE) from 6 normal adult cats were investigated using parvalbumin (PA) immunohistochemistry. Fibre types I, IIA and IIB were identified in all muscles....

Zusammenfassung:	The composition and size of muscle fibre types in the hyopharyngeus (HP), thyropharyngeus (TP), cricopharyngeus (CP) and cervical oesophageal muscle (CE) from 6 normal adult cats were investigated using parvalbumin (PA) immunohistochemistry. Fibre types I, IIA and IIB were identified in all muscles. HP and TP revealed predominance of type II fibres (74.8% and 75.2%, respectively), whilst CP and CE showed predominance of type I fibres (72.6% and 82.2%, respectively). The mean diameter of narrow fibres was greater in type II (23.9
