Study Notes
Types of Sensation and Receptors
- Extteroceptors detect stimuli from the outside of the body.
Nociception and Pain
- Nociceptors detect painful stimuli, and their main function is to respond to tissue damage or potential damage.
Sensory Neurons
- Unipolar sensory neurons can respond to only one type of stimuli.
Transduction and Sensation
- The purpose of transduction is to convert environmental stimuli into electrical signals that can be interpreted by the central nervous system.
Proprioception and Movement
- Proprioceptors detect changes in muscle length and tension, providing information about body position and movement.
Types of Sensory Receptors
- Nociceptors are the type of sensory receptor most sensitive to pain (nociception).
- Photoreceptors are responsible for detecting light.
Receptor Potentials and Signal Transduction
- When a receptor potential is produced by vision, hearing, equilibrium, or taste receptors, it generates an electrical signal that can trigger an action potential.
Rapidly Adapting Receptors
- The main function of rapidly adapting receptors is to detect rapid changes in stimuli.
Encapsulated Nerve Endings
- The purpose of encapsulated nerve endings in the sensory system is to provide a protective covering for sensitive nerve endings.
Mechanoreceptors
- Mechanoreceptors detect pressure or stretch, and are classified as a type of sensory receptor.
Receptor Sensitivity
- When there is a change in sensitivity to long-lasting stimuli, the responsiveness of a receptor may decrease, a phenomenon known as adaptation.
