Document Summary
Hap101 week 11/chapter 16: sensory, motor and integrative systems. Lo 16. 1: define sensation and discuss the components of sensation. Sensation: the conscious or subconscious awareness of changes in the external or internal environment. The nature and type of reaction generated vary according to the ultimate destination of nerve impulses that convey sensory info to the. Perception is the conscious interpretation of sensations and is primarily a function of the cerebral cortex. Sometimes, we do not have perception of sensory info because it does not reach the cerebral cortex. Sensory modality: each unique type of sensation (e. g. touch, pain, vision, hearing, etc. ). A sensory neuron only carries information for one sensory modality. They are grouped into two classes: general senses: includes both somatic and visceral senses. Somatic senses include tactile sensations, thermal sensations, pain sensations, and proprioceptive sensations (perception of static and non-static limbs).
