A. For the lateral ventricles, write 2-3 sentences describing:
(i) its location in the brain
(ii) its neurological relationship to nearby structures
(iii) any neurologic disorders associated with its dysfunction.
ANSWER: Right and left lateral ventricles are situated in their respective hemisphere of the cerebrum. They have horns which project into the frontal, occipital and temporal lobes. The anterior horn connects to the 3rd ventricle by interventricular foramen. The boundary facing the exterior to the ventricular curvature is bounded by corpus collosum the roof consists of the posterior surface of genu. The body of the lateral ventricle has the roof along with tapetum. The tail of caudate nucleus forms the upper portion of the lateral edge. The posterior horn impinge itself into the occipital lobe of the brain and the temporal horn impinge into the temporal lobe. Its floor is formed by hippocampus. Colpocephaly is a neurological condition where there is abnormal enlargement of posterior horn of lateral ventricle. This enlargement occurs when there is a lack of thickening of white matter in the posterior cerebrum.
