Which of the following is an example of the process of transduction? Taste acceptance and rejection are processed in the hindbrain, while emotional reactions to taste are processed in forebrain. Different qualities of taste (sweet, salt, sour, bitter) activate different receptor cells in the taste buds. O A photon of light strikes a photopigment in a rod cell, changing the photopigment, which causes the close of ion channels, which reduces the rod's output of neurotransmitter. Molecules of alcohol evaporate from the surface of a liquid and get into your nasal passages.
Anatomy and Physiology of Special Sensory Organs
Sensory organs can be labeled as special sensory structures that permit sight, hearing, odor, and flavor. Sensory structures permitting proprioception, touch, thermal, and pain perception can be classified as more advanced sensory organs. The sensory neurons are trained to find out modifications in the external and internal conditions so that a person's body can react to that change. A stimulus is the first signal that is recognized by any sensory receptor of the body. Stimulus is an impulse generated when there is a change in the surroundings of a person. For example, a heated environment will alert the brain through the thermal sensory organs and generate a reflex accordingly.
Sensory Receptors
The human sensory system is one of the most complex and highly evolved structures, which processes a myriad of incoming messages. This well-coordinated system helps an organism or individual to respond to external stimuli, appropriately. The sensory receptors are an important part of the sensory system. These receptors are specialized epidermal cells that respond to external environmental stimuli. These receptors consist of structural and support cells that form the peripheral unit of the receptor and the neural dendrites which receive and detect the external stimuli.
