When a single photon from a source of light hits the retina in the eye, it triggers a signal that travels along the optic nerve to the occipital lobe of the brain. The interaction of a photon with the photoreceptors in the retina first causes the movement of sodium ions into a sensory neuron. What happens after the movement of sodium ions? a. Sodium ions move out of a sensory neuron. b. Potassium ions move out of a sensory neuron. c. Sodium ions move into an interneuron. d. Potassium ions move into an interneuron.
A virus has destroyed the bipolar cells in a patientwhat symptoms might occur? Rod cells will no longer respond to light. B. cells will no longer be able to produce photopigments, therefore the patient will no longer be able to detect colour C. cells will no longer be able to produce an action potential. O D. The patient will have a visual impairment.
Select the statement that best describes how the nervous system encodes sensory input. a. Neural coding permits precise assessments of the absolute intensity of a stimulus. b. Neural circuits in sensory systems are always convergent. c. The neural representation of sensory input is an exact replica of the physical world. d. The neural representation of sensory input emphasizes some sensory qualities over others. e. Each neuron must be optimized to code both resolution and sensitivity
The amount of glutamate release from photoreceptors of the vertebrateeye is highest whena. an animal is in full sunlight.b. an animal is in a completely dark place.c. an animal is in a dimly lit place.d. Na+ channels of the photoreceptors are closed.e. Both a and d are true.
Which of the following statements about sensory systems is NOT true? a. Sensory transduction involves the conversion (by either a direct or indirect mechanism) of a physical or chemical stimulus into changes in membrane potential difference. b. Sensory adaptation plays a role in the ability of organisms to discriminate between important and unimportant information. c. The term "sensory adaptation" refers to the process by which a sensory cell becomes less sensitive, or less responsive, to a continuing source of stimulation. d. In general, a stimulus causes a change in the flow of charged ions across the plasma membrane of a sensory receptor cell. e. The more intense a stimulus is, the greater the peak depolarization of the action potentials fired by the sensory neuron.
Taste buds are sensory receptors for taste located on the tongue. When a person eats a spicy food, receptors on the tongue pick up a stimulus. The stimulus initiates the movement of ions across the membrane. If the threshold level is reached, an action potential is generated and a signal is sent to the brain telling the brain that the food is spicy. The reason that some individuals have a higher tolerance to spicy food than others is due to a difference in the a. duration of the refractory period b. number of Na+/K+ ion exchange pumps c. strength of the stimulus d. threshold level
Please ASAP Thank you. 1. What is the basis for human color vision? a. Different spectral sensitivity of the three different kinds of retinal cones b. Different spectral sensitivity of rods c. Spectral filters in the eye that separate light into its spectral components before it reaches the retina d. Processing that occurs in the neural circuits in the retina 2. Imagine yourself locked in a room without any light source for 30 minutes. Then let’s imagine that someone shines a red light in the corner of the room. One should expect that the rod cells in your retina will: a. Be more sensitive to the red light after the 30 minutes of darkness as compared to earlier b. Be less sensitive to the red light after the 30 minutes of darkness as compared to earlier c. Be equally sensitive to the red light as before the 30 minutes of darkness e. Rod cells do not respond to red light
