Reception

Definition

Reception is the initial stage in sensory processing where a sensory receptor detects a stimulus. It involves the conversion of external stimuli into neural signals.

5 Must Know Facts For Your Next Test

1. Receptors are specialized cells that can detect specific types of stimuli, such as light, sound, or chemicals.
2. Reception occurs at the level of the sensory receptors located in various organs and tissues.
3. Different types of receptors include photoreceptors for light, mechanoreceptors for pressure and touch, and chemoreceptors for taste and smell.
4. The process of reception leads to the generation of an action potential if the stimulus is strong enough to reach the threshold.
5. Receptor sensitivity and specificity determine how effectively a stimulus can be detected.
