Lateral ventricle
A communicating cavity in the brain that is part of a system of four communicating cavities that are continuous with the central canal of the spinal cord. The two lateral ventricles are located in the cerebral hemispheres, one in each hemisphere. Each consists of a triangular central body and four horns. The third and fourth ventricles are located in the center of the brain. The lateral ventricles communicate with the third ventricle through an opening called the interventricular foramen. Both lateral ventricles are filled with cerebrospinal fluid.

- Lattice dystrophy
A form of hereditary corneal dystrophy in which there is an accumulation of amyloid deposits, or abnormal protein fibers, throughout the middle and anterior stroma of the cornea. These deposits in the stroma appear on an eye examination as clear, comma-shaped overlapping dots and branching filaments, creating a lattice effect. Over time, the lattice lines […]
