Document Summary

Sensory neuron that sits inside the muscle, which causes your leg to jerk. Stretch receptor inside muscle detects sudden change inside the muscle. Sensory organs transform energy upon them into chemical messages, then electrical signals, where they are sent to the cns. Need to be able to detect a particular signal by a cell, where it is transduced into an electrical signal, that can be passed onto the cns. It then has to be amplified and transmitted to the cns, integrated in the brain, where it then leads to a response. Transduction is the change from whatever the stimulus is into the basic language of the cns, which is ap. We can have a neuron that sits in the periphery that has a receptor membrane that creates receptor potentials, where ap are then created. Or we can have a long dendrite, and the cell body is sitting in the cns.
