Select the options that properly describe the function and features of rods. O The absorbance of rhodopsin in the rods is much more sensitive than in the cone opsins. The absorbance of rhodopsin in the cones is much more sensitive than in the rods opsins. O sensitive to bright light conditions. Rods are sensitive to vision in bright light conditions. In low light conditions rods perceive color as blue scale. OIn low light conditions rods perceive color as gray cale. O sensitive to low light conditions. O Rods are sensitive to low light conditions. OA bright blue light would stimulate rods more than cones. O Rods are sensitive to vision in low light conditions. O Low light conditions are viewed in blue scale. Rods are sensitive to bright light conditions.
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.
