A nociceptor detects a. Olfaction refers to the sense of. Rods are more sensitive to light than cones b.

Which of the following statements about the mammalian vomeronasal organ is true. Correct option is B Rods and cones are photoreceptors in the human retina. They provide our color perception.

Photoreceptors in the retina are classified into two groups named after their physical morphologies. Are most numerous at the periphery of the retina. Which of the following is true about rod photoreceptors.

They operate most efficiently under daylight conditions. C Three types of color-sensitive photoreceptors exist. Cones are active at higher light levels photopic vision are capable of colour vision and are responsible for high spatial acuity.

An olfactory receptor is a type of interoceptor. In complete darkness full regeneration of cone photopigments is delayed and the eyes are adapted to the darkness first. B Three types of color - sensitive photoreceptors exist.

Stimulation of a gustatory receptor produces a generator potential. Individual cones are more likely to synapse with individual bipolar cells e. Red green and yellow.

Which of the following is true about photoreceptors. Perception of a sensation is primarily a function of the brain stem. Which of the following is true regarding receptive fields.

However both types of light can produce images. Which of the following is true concerning photoreceptors in the retina. Rods are concentrated at the periphery and function well in dim light.

Cones in the retina a. Check all that apply they are sensory neurons they are ganglion cells they are bipolar cells O they are cones O they transduce light O they are presynaptic neurons. The human eye has three types of color-sensitive photoreceptors.

Rods are responsible for night vision or the vision in dim light. Nociceptors are rapidly adapting receptors. The macula is the most sensitive part of the retina with millions of tightly packed photoreceptors.

A Rods absorb light throughout the visual spectrum but confer only gray tone vision. Which of the following is true about photoreceptors. C In dim light images are focused directly on the rods in the fovea centralis.

226 Which of the following is true about photoreceptors. A Rods absorb light throughout the visual spectrum but confer only gray tone vision. Rods allow us to perceive vivid colors d.

Red green and yellow. Based on this information which of the following is true regarding the fovea. The trigeminal nerve is its motor arm carrying pain information.

Generally there are 4 major types of mechanical receptors in glabrous hairless skin they are 1Pacinian corpuscles 2Meissners corpuscles 3Merkels disc. Rods are concentrated in the fovea of the retina and function well in dim light. Red green and yellow.

Rods help with high visual acuity while cones help with peripheral vision e c. B In dim light images are focused directly on the rods in the fovea centralis. Which of the following is true about photoreceptors.

They provide low-resolution dim-light night vision. Sensory receptors that respond to mechanical stress or distortion are called Mechanical receptors. D If all cones are stimulated equally all colors are absorbed by the cones and the.

They provide high-resolution color visionRods have a small narrow cylindrical outer segment. B In dim light images are focused directly on the rods in the fovea centralis. Cones are concentrated in the fovea of the retina and function to detect colours.

A muscle spindle is an example of a proprioceptor. Which of the following statements is true. It integrates the olfactory information before sending it to the brain.

Therefore only black white and all shades of gray are seen in dim light. It mostly detects pheromones and other chemical signals. A Rods absorb light throughout the visual spectrum but confer only gray tone vision.

Rods do not provide color vision. Rod cells are highly sensitive to light and function in nightvision whereas cone cells are capable of detecting a wide spectrum. If all cones are stimulated equally all colors are absorbed by the cones and the color perceived is black In dim light images are focused directly on the rods in the fovea centralis Rods absorb light throughout the visual spectrum but confer only gray tone vision Three types of color-sensitive.

They do not mediate colour vision and have a low spatial acuity. D If all cones are stimulated equally all colors are. It interacts with the olfactory system to amplify the signal.

The fovea is the area of the eye with the greatest number of photoreceptors used for sensing high light intensities. QUESTION 36 Which of the following is true about photoreceptors. It increases the sensitivity of the olfactory system.

Which of the following is true regarding the corneal reflex. C Three types of color-sensitive photoreceptors exist. CN VII is the motor.

Cones encodes color by expressing a. A If all cones are stimulated equally all colors are absorbed by the cones and the color perceived is black.
