PDF-INTRODUCTION The Drosophila peripheral nervous system

The stereo typed pattern of the PNS results from the pattern in which neural precursors arise from the ectoderm during development Ghysen and DamblyChaudire 1989 Neural precursor formation is an important model for the processes of cell spec i64257c.

To sense, interpret, and respond to internal and external environmental changes to maintain a steady state in the . body (homeostasis). The nervous system is divided into two major structures: .

(CNS) AND THE PERIPHERAL NERVOUS SYSTEM (PNS) Learning objectives: The nervous system in humans is a complex integration of organs like brain, spinal cord and sensory organs along with nerves.
