↓ ervous System Organization
· The nervous system is a
group on cells /specialized : neurons) that recieve Sensory Stimule and transmit them to Ef-
fector organs
. The stimul an come from outside or inside the body
. These situmi can be stored in
utmony , or
go through Efferent Pathways to the Receptor organs .
-
· The nearous system is divided into two main parts :
- & Central Nervous System 2 Peripheral Nervous System
↳ main centers for correlation and ↳ conduction of information to
integration of information And from the crus
