Dogfish head. Light micrograph of a transverse section through the head of a lesser spotted dogfish (Scyliorhinus canicula),in the region of the eyes (upper left and upper right). Between the eyes is the cartilaginous cranium enclosing the brain. The brain's cerebellum,fourth ventricle (upper space),and third ventricle (lower space) are seen. The eyes show the outer eyelids,the cornea,the circular lens and cup-shaped retina. Underneath the eyes is the mouth (buccal) cavity. The bubble-like areas under the skin (left and right) are the ampullae,opening to the surface,which control balance and pressure differences.
