GlrFIG 5 Muscle arms of the head muscles

GlrFIG 5: Muscle arms of the head muscles.

Posterior head muscles reach the muscle plate at the level shown (insert). The arms turn inward near the GLRDR cell body (only the anterior edge of the soma is seen) and their terminal branches insinuate between the CEPsh and neuron processes to reach between the neuron layer and the inner GLR process layer. The muscle plate is separated from the neurons by a basal lamina (not shown). Only the right side structures are labeled. Bar, 1 μm. (Image source: N2U [MRC] A190-17.)
