B44 innervates the inner leaflets of the I4 muscle complex. A, Camera lucida drawing of B44 is shown.Bn 2 and Bn 3, Buccal nerves 2 and 3. B1, Semischematic drawing of the radula and attached musculature is shown. The I4 muscle complex has been flipped back to expose the inner leaflets. B2, Intracellular stimulation of B44 (bottom) elicits EJPs recorded intracellularly from a fiber of the dorsal inner leaflet (top). More specifically, EJPs were recorded from the posterior side of the dorsal leaflet, i.e., the side that is closest to the outer leaflets. B3, Stimulation of B44 (bottom) also elicits EJPs that can be recorded from the anterior face of the inner leaflets (top), i.e., the side shown in B1. Note that EJPs recorded from the posterior face of the inner leaflets are larger than those recorded from the anterior face. The posterior face of the inner leaflets lies directly under the tissue that contains processes of B51.
