[ adjective ] (zoology) at or near the hind end in quadrupeds or toward the spine in primates
Used in print (J. W. C. Hagstrom et al., "Debilitating muscular...)The myocardium of the posterior base of the left_ventricle was replaced by gray scar tissue over a 7.5 cm. area . Microscopically , sections from the posterior base of the left_ventricle of the heart showed several large areas of replacement of muscle by fibrous_tissue . (E. Gellhorn, "Prolegomena to a theory of the emotions"...)On_the_other_hand , the temporary reduction in hypothalamic excitability through the injection of a barbiturate into the posterior hypothalamus causes a lessening in frequency and amplitude of cortical strychnine spikes until the hypothalamic excitability is restored . Apparently , a positive_feedback exists between the posterior hypothalamus and the cerebral_cortex . Since electrical stimulation of the posterior hypothalamus produces the effects of wakefulness while stimulation of the anterior hypothalamus induces sleep , it may be said that the reactivity of the whole organism is altered by a change in the autonomic reactivity of the hypothalamus . |
