Stimulation of the sensory receptor activates the associated afferent neuron, which carries information about the stimulus to the central nervous system. In one, a neuron works with a sensory receptor, a cell, or cell process that is specialized to engage with and detect a specific stimulus. There are two broad types of cellular systems that perform sensory transduction.
This process is called sensory transduction. Although the sensory systems associated with these senses are very different, all share a common function: to convert a stimulus (such as light, or sound, or the position of the body) into an electrical signal in the nervous system. Vestibular sensation, which is an organism’s sense of spatial orientation and balance, proprioception (position of bones, joints, and muscles), and the sense of limb position that is used to track kinesthesia (limb movement) are part of somatosensation. Additionally, we possess general senses, also called somatosensation, which respond to stimuli like temperature, pain, pressure, and vibration. Humans have five special senses: olfaction (smell), gustation (taste), equilibrium (balance and body position), vision, and hearing.
Senses provide information about the body and its environment. Explain the concept of just-noticeable difference in sensory perception.Describe three important steps in sensory perception.Identify the general and special senses in humans.
