Figure 3From: Dopaminergic neurons in the brain and dopaminergic innervation of the albumen gland in mated and virgin helisoma duryi (mollusca: pulmonata)Fluorescence micrograph of glyoxylic acid treated tissues. a: the albumen gland. Dopaminergic nerve endings form a tract. Neuronal cell bodies are seen within the tract (arrowhead). b: the albumen gland. Dopaminergic nerve endings form varicosities (arrowheads). c: a part of the albumen gland (AG) with attached carrefour (cf). Dopaminergic nerve endings form a tract (arrowhead) that originates in the carrefour. Scale bar = 100 μm.Back to article page
