Which receptor cells help distinguish different wavelengths of light?
Cones are the receptor cells in the retina that help distinguish different wavelengths of light. There are three types of cones that are sensitive to different wavelengths (red, green, and blue), allowing us to perceive a wide spectrum of colors.
How does olfaction occur?
Within the nasal cavity, odorant molecules interact with the cilia on odorant receptor cells. The binding of odorant molecules onto receptor proteins causes a net change in the membrane permeability of the receptor cells which then causes an action potential to be generated by the receptor cell. Unlike other senses, olfaction is not redirected by the Thalmus. It instead goes directly from the afferent receptor cells to the olfactory bulb. From the olfactory bulb, the action potential is sent directly to the cerebral cortex, specifically the limbic system (this is why there is a large emotional association with smell).
The same receptor can have different effects depending on the properties of the?
ligand that binds to it. For example, a receptor can trigger different signaling pathways or cellular responses if it binds to different ligands, even if they bind to the same binding site on the receptor. This is known as ligand-dependent receptor activation.
Can a receptor be an antigen?
No, they are entirely two different things. What might stimulate a receptor could be an antigen.
What makes visible light different colors?
light is made up waves. Different energy of waves are called wavelengths. With blue having the most energy and red having the least. You can see different colors because your eye ability to distinguish between different wavelengths. Our eyes can see 3 colors red, green and blue. When a light high energy Weight length "blue" is focused into the eye it will have enough energy to excite a nerve in your eye retina to cause the cells to fire and your brain will interpret this as a blue light. When a lower energy wave length like green is focused on the blue receptor there is not enough energy to cause it to fire. however surrounding cells better tuned for green will fire, telling the brain the light is green. the color sensitive cells are called cone cell. We also have a different type of cell called rods and that just detect light levels ( this is why in low light you cannot see colors as a cone cell are not as sensitive as rod cells). With information about its wavelength "color" and information about its intensity "brightness" Your brain can interpreted an object its color.

Which receptor cell is associated with seeing colors?
Cone cells are the receptor cells in the retina that are associated with seeing colors. There are three types of cone cells that are sensitive to different wavelengths of light, allowing us to perceive a wide range of colors.
Photosensitive receptor cells of the retina make the perception of color possible?
Photosensitive receptor cells in the retina, called cones, are responsible for color vision. These cones contain different pigments that respond to different wavelengths of light, allowing us to perceive a range of colors. The brain processes the signals from these cones to create a perception of color.

What is the difference between visble and invisible spectrum?
The visible spectrum refers to the range of light wavelengths that are visible to the human eye, which includes colors from violet to red. The invisible spectrum, on the other hand, includes wavelengths outside of the visible range, such as ultraviolet and infrared light, which cannot be seen by the human eye without special equipment.
Why tongue may be considered to be both a receptor and an effector organ?
It is a receptor because it has gustatory organs called taste buds that have chemoreceptors and it is an effector because it is also made of muscles that help you manipulate and swallow food, as well as speak. So, it does both recepting and effecting.
What is the cell called in the nose?
The cells responsible for our sense of smell are called neurons, specifically olfactory receptor neurons. They are linked directly to the brain, and respond to different chemical signals to generate what we then perceive as smells and odors.
What is the name of the area of receptor cells in the back of the eye?
This area is called the retina. It consists of different sets of receptor cells that are specialized in their function to aid in the perception of light and colour.
