co ordination
changes that occur in the external or internal environment of the
organism
co ord involves :
-
stimulus : external or internal environmental change that evokes
a reaction
control centre : CNSC brain + spinal chord )
response effect : reaction to the stimulus
how does INFO flow through body
stimulus detected by receptors in sense organs
converted to impulse by receptors
Impulse travels to CNS V10 a sensory neuron
sensory neuron synapses with Inter neuron in CNS
Inter neuron synapses with motor neuron
motor neuron conducts impulse to effector ( muscle / Gland )
appropriate response occurs
