Final answer:
Information obtained from sensory receptors includes bitter taste detected by chemoreceptors, light brightness detected by photoreceptors, duration of a note registered by auditory receptors, and the placement of an item in hands determined by mechanoreceptors in the skin.
Step-by-step explanation:
Sensory receptors are specialized cells that respond to specific types of stimuli, such as light, sound, pressure, and chemicals. There are diverse types of sensory receptors including chemoreceptors, mechanoreceptors, and photoreceptors, each attuned to different sensory modalities. For instance, taste information comes from chemoreceptors in taste buds that detect bitter, sweet, salty, sour, and umami sensations. The brightness of light is detected by photoreceptors in the eyes, which capture visual information. Membrane potential changes are not directly perceived by our senses but underlie the function of all neurons, including sensory receptors. The duration of an instrumental note is encoded by auditory receptors which recognize sound information. Lastly, mechanoreceptors in the skin help discriminate the placement of an item in your left vs. right hand, a part of the tactile or touch sensory system.
The correct examples that demonstrate information obtained directly from sensory receptors in the provided choices are:
- Bitter - Taste, detected by chemoreceptors in the taste buds
- Brightness of light - Vision, detected by photoreceptors in the retina
- Duration of an instrumental note - Hearing, detected by auditory receptors in the ears
- Placement of an item in your left vs. right hand - Touch, detected by mechanoreceptors in the skin
sensory receptors such as chemoreceptors, photoreceptors, and mechanoreceptors detect specific stimuli including taste, light intensity, sound duration, and touch placement; membrane potential underlies neuronal function but is not directly sensed.
