Description
Abstract
Sensory innervation of lingual musculature
was studied in young adult Wistar rats using
retrograde labeling by horseradish peroxidase
(HRP) and combined silver impregnation and
acetylcholinesterase (AchE) methods. Intra-lingual
injection of HRP resulted in labeling of neuronal
somata in the trigeminal, superior vagal, and second
cervical spinal (C,) ganglia. When HRP was directly
applied to the proximal stump of severed hypoglossal
nerve, labeling occurred only in the cervical and
superior vagal ganglia. Morphometric analysis
revealed that the labeled neurons were of the smallsized
category in all ganglia. However, in the
trigeminal and C, ganglia, labeling occurred also
among the medium-sized neurons. Combined silver
and AchE preparations from lingual muscles revealed
the absence of typical muscle spindles. Instead. there,
were free and spiral nerve terminals in the
interstitium. and epilemmal knob-like or bouton-like
endings surrounding non-encapsulated muscle fibers.
These terminals showed AchE -ve reaction in contrast
to the motor ones. Few ganglionic cells were scattered
along the hypoglossal nerve with uniform AchE +ve
reaction in their perikarya. This indicates that
medium-sized neurons in the trigeminal and C2 ganglia, and probably sensory neurons along the
hypoglossal nerve mediate lingual muscle sensibility
perceived by atypical sensory terminals.
