Document Summary
Detects change, modifies its physiology, and that of other organs functionally coordinates the boy organs = homeostasis. Receive information from receptor cells and organs specialised to detect changes in body and external environment. To process information and determine appropriate response (neural integration) Issue commands to effectors, cells and organs (mainly muscle and gland cells) to carry out the response. Can be stimulated by chemicals, light, heat, or mechanical distortion. Secretory cells rich in rer and golgi apparatus. The task of the neuron depends on its position in the developing ns position is specified by patterns of gene expression (segmental + dorso-ventral patterning). New neurons are born on the ventricular surface of the neural tube most daughter cells pile up around the central canal. Some migrate away to the outer surface of the neural tube. Receptor distinct + specialised cells cells associated with epithelial support cells.
