Text Appearing Before Image:
110 THE BIOLOGY OF THE FROG The anterior wall of the forebrain produces a pair of pouches, the cerebral hemispheres, which finally become the largest part of the brain. Their cavities, the lateral ven- tricles, communicate with the third ventricle by an opening, the foramen of Monro,
Text Appearing After Image:
so Sp Fig. 37.—Cross section of a frog embryo. AR, arehenteron; MS, mesoblastic somites; N, notochord; JSS, neural crest; M, medullary tube ; PR, pronephros; SN, subnotochordal rod; SO, SP, somatic and splanchnic mesoderm. (From Morgan, after Marshall.) The nerves arise as paired outgrowths both from the brain and cord, pushing their way between the cells of the other organs, dividing and ramifying, as they push outward toward the various parts they supply. The spinal nerves begin as two independent outgrowths, representing the dorsal and ventral roots; these soon unite into a single nerve.
