Amphibian Central Nervous System

The central nervous system of a stereotypical amphibian.  An entire dorsal dissection of a brain (1) shows the cerebral hemispheres (Hem), the optic lobes (C. big), the cerebellum (Crbl) and the medulla oblangata (M. obl) amongst other strutctures.  The other views represented are a horizontal longitudinal section (2), a vertical longitudinal section (3), an entire ventral dissection with circulatory and digestive systems pulled to the right side (4), partial ventral dissection of M. obl and C. big with hypothalamus removed (5), a cross section of the spinal cord with associated nerves and ganglia (6) and a representation of a mechanosensory hair cell receptor (7) showing neurons associated with “hairs” contained within a flexible gell cap.
