PSL201Y1 Lecture : Somatosensory System
Document Summary
General principles of sensory physiology: receptor physiology. The sensory receptors are specialized nerve endings or a. Sensory system deals with what you perceive through touch: general principles of sensory physiology, the somatosensory system smell, sound, vision and hearing. This is all possible due to the existence of specialized sensory receptors that can detect specific energy from the environment. An example are photoreceptors found in the eyes to detect light. separate cell that detects a sensory stimulus such as touch. Instead of post synaptic protein receptors, we have sensory receptors that receive signal from the outside (touch, vision etc. ). These signals will be transmitted to the cns. The sensory receptors are embedded in sensory cell membranes. The receptors proteins of the sensory cells will change shape when specific energy (chemical, mechanical) is received which will allow a chain of events to occur.
