Concept explainers
The process in which incoming sensory stimulation is converted to electrical signals in neurons is called
- a. an action potential.
- b. sensory reception.
- c. perception.
- d. sensory transduction.
- e. perceptual transduction.
Introduction: The senses allow an individual to know about its environment. A sense consists of systems that have specialized cells. These cells help to detect a specific type of physical and chemical stimulus, and send signals to the central nervous system.
Answer to Problem 1TY
Correct answer: Sensory transduction is the process in which incoming sensory signals are converted to electrical signals in the neuron. Hence, the correct answer is option d.
Explanation of Solution
Reason for correct answer:
The sensory system of an animal is responsible for the conversion of a physical or chemical stimulus from their body or external environment into signals. This causes a change in the neuron’s membrane potential. This process is known as sensory transduction. This process involves changes in a cell, such as opening and closing of ion channels which causes an action potential in the neurons.
Option d. is given as, “sensory transduction”.
The process in which incoming sensory stimuli are converted into electrical signals is known as sensory transduction. Hence option d. is correct.
Reasons for incorrect answer:
Option a. is given as, “an action potential”.
An action potential is the difference in the potential needed for impulse transmission. Hence, option a. is incorrect.
Option b. is given as, “sensory reception”.
When a sensory receptor is activated in response to any signal, it is known as sensory reception. Hence, option b. is incorrect.
Option c. is given as, “perception”.
The awareness of the stimulus is known as perception. Hence, option c. is incorrect.
Option e. is given as, “perceptual transduction”.
The conversion of a perceptual signal is known as perceptual transduction. Hence, option e. is incorrect.
Hence, the options a., b., c., and e. are incorrect.
The process in which the incoming sensory stimuli are converted into electrical signals is termed as sensory transduction.
