Question

If a person sustains damage to axons leading from

sensory receptors to the central nervous system, which

step or steps of sensory perception will be affected?

Short answer

The step of reception of stimuli and collection of sensory information will be affected.

Step-by-step solution

Introduction 

The human sensory system encodes four parts of sensory information that include the kind of stimulus, the time, intensity, and the location. So, the action potentials that are sent by the afferent axons encode only one kind of input. In other sensory units, there is a maintenance of this distinction between the senses.

Detailed explanation 

• The brain’s function to receive stimuli is halted due to the compromise of CNS in getting sensory information from the receptors.
• The process of activating sensory receptors through stimuli such as chemical, mechanical or temperature stimuli is covered under the primal phase of sensation i.e., reception. Thereafter, the receptor produces a response to the received stimuli.
• One of the basic functions of the sensory system is to convert or change the sensory signal received into a electrical signal. This shift takes place by the name receptor potential at the sensory receptor.
