To list: The four functions that are common to all sensory pathways with their description.
Introduction: The process that converts the physical or chemical stimulus into a receptor potential is known as sensory transduction. When a stimulus is given, it leads to the closing and opening of ions channels that results in receptor potentials.
Explanation of Solution
The four functions that are common to all sensory pathways are as follows:
- Transmission:
- Integration:
- Perception:
- Amplification and adaptation:
The sensory information is transmitted as an action potential, and it moves to the CNS (central nervous system). The frequency of generated action potential and quantity of released neurotransmitter determines the magnitude of a receptor potential.
Graded potential from receptors sums up and starts the integration of the information from sensory neurons. This information integrates with CNS and complex receptors.
Sensory neurons pass impulse that routes into different parts of the brain. These parts of the brain interpret these impulses and produce the perception based on different stimuli.
Amplification is a process that strengthens the energy of a stimulus with the help of accessory structures of sense organs. The sensitivity of receptors cells decreases with continuous stimulation. This is known as sensory adaptation.
Thus, four functions that are common to all sensory pathways are transmission, integration, perception, and amplification and adaptation.
