The retina in the back of your eye contains rods and cones. Rods allow us to differentiate between black and white, or light and dark. Cones allow us to distinguish between colors. The periphery of our vision is composed mainly of rods and the central part of out vision is composed mainly of cones. The fovea is a small indentation in the retina, directly in the center of our vision. It is composed of only densely packed cones. This is the reason why we often have a hard time seeing something in the dark unless we look slightly away from it.

∙ 11y agoThe receptors are arrayed along the back of the interior of each eye, in the tissue called the retina.
There are two types of cells that act as photoreceptors in the eye: rods and cones. Rods detect only the presence or absence of light without distinguishing between colors, thus giving black and white vision (as at night). Cones detect colors in the images but are less sensitive, i.e. they require more light to function.

Are cold or heat receptors more numerous?
More cool receptors than warm receptors in the skin.
The two types of receptors that bind acetylcholine are?
nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
What is punctuate distribution of cutaneous receptors?
Cutaneous Sensory Receptors are clustered in certain spots instead of being uniformly distributed. This clustering is called punctate distribution.
What layer of skin contains sensory receptors for touch?
The Dermis layer contains the sensory nerve fiber, so it is the Dermis layer that contains sensory receptors for touch.
Chemoreceptors that detect odors are called what?
olfactory receptors
The dim light receptors are the?
rods are our or dim light and peripheral vision receptors
What are the receptors for bright light vision called?
cones
Where are hormone receptors for non- steroid hormone located?
where are receptors for non-steroid hormones located
Why is your front vison better than your side?
Your front vision is the best because around the center of the retina (except for the blind spot where the optic nerve enters) is where most of the vision receptors are. You don't have as many receptors on the areas corresponding to your peripheral vision.
Where are olfactory receptors located?
In vertebrates the olfactory receptors are located in the cilia of the olfactory sensory neurons. In insects olfactory receptors are located on the antennae and other chemo sensory organs.
Where are temperature receptors located in human body?
Sensory receptors for cold are located in the dermis, the are formally called free nerve endings.
What are the receptors in the eye?
You have rod cells and cone cells as receptors in your eye. Rods are for intensity of the light. Cone cells are for color vision.
What Specialized visual receptors play a key role in night vision and peripheral vision?
The "rod" type photoreceptors of the retina.
What kind of sensory receptors are located everywhere in the body but the brain?
Pain Receptors
Which type or receptors are located everywhere in the body except for the brain?
pain receptors
What are the five general areas of sensation?
General sensory receptors such as light touch and temperature receptors are located over the entire surface of the body. There are no specific areas where these receptors are located.
Where are the hearing receptors located?
cochlea
