Lecture Overview Week 1 Embryonic Development Gastrulation is a phase early in the embryonic development of most animals during which the singlelayered blastula is reorganized into a multilayered structure known as the gastrula . A. Bacterial Infections of the Nervous System. 1. Bacterial Meningitis. A) Although bacteria can infect the brain, spinal cord, and peripheral nerves, they more commonly infect the meninges and cerebrospinal fluids resulting in meningitis. Central. Nervous. System.
