    Study Notes

    Sensory Receptors and Their Functions

    • Sensory receptors detect stimuli from the environment and convert them into signals.
    • The process of converting one form of energy into another is known as transduction.
    • The sensory process involves three main stages: detection, transduction, and perception.

    Sensory Adaptation

    • Sensory adaptation refers to the diminished sensitivity to a stimulus as a result of constant exposure.
    • This phenomenon allows organisms to focus on changes in the environment rather than constant stimuli.

    Information Transmission

    • Sensory receptors transmit information regarding the type, intensity, and duration of the stimulus.
    • This information is crucial for the body’s ability to react appropriately to various environmental conditions.

    Role of Receptors

    • Receptors play a main role in detecting sensory stimuli and initiating the sensory process.
    • They are specialized to respond to specific types of stimuli such as light, sound, and temperature.

    Types of Receptors

    • Tonic receptors adapt slowly and continue to respond to continuous stimulation, providing ongoing information about the stimulus.
    • Nociceptors, which detect pain, are primarily located in the skin, joints, and organs throughout the body.

    Chemoreceptors and Balance

    • Chemoreceptors help maintain calcium and electrolyte balance by sensing chemical changes in the environment.

    Mechanoreceptors

    • Mechanoreceptors are responsible for sensing vibration, touch, pressure, stretch, and tension in the body.

    Structure of Receptors

    • Encapsulated nerve endings are wrapped in connective tissue, enhancing their sensitivity to stimuli.

    Sensory Pathways

    • Most sensory information takes the ascending pathway to reach the cerebral cortex, where perception occurs.
