[Fine structure of the facial nerve nucleus of the domestic hen].
The facial nucleus of the domestic hen is composed of a dorsal, intermediate, and ventral portion. The dorsal and intermediate one consist of medium-sized and rare small polygonal and oval neurons. The ventral subnucleus shows medium-sized and large neurons. Electronmicroscopically, the latter exhibit numerous Nissl bodies with short cisterns and a lot of polysomes. The small neurons comprise few but large Nissl bodies with long cisterns of the rough endoplasmic reticulum. According to the shape of synaptic vesicles and the number of mitochondria three distinct types of synapses can be distinguished.
