Question

Which of the following statements is correct regarding receptors in the skin?

T HARITHA · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Skin Receptor Types and Function
	**Related Topics**: Mechanoreceptors, Nociceptors, Sensory Pathways, Encapsulation, Receptive Fields
	**Prerequisites**: Basic knowledge of skin anatomy and sensory physiology.
## SOLUTION PATHWAY
**Given Information**:
	*  Multiple statements about skin receptors.
	*  One statement is correct.
**Method & Steps**:
	1. Analyze each statement based on knowledge of skin receptors.
		Reasoning: Assess the accuracy of each statement against known physiological principles. 
	2. Evaluate statement A: All skin receptors are encapsulated.
		Working: This is incorrect as free nerve endings (nociceptors and some thermoreceptors) are not encapsulated.
		Key Point: Encapsulation is a characteristic of some but not all skin receptors.
	3. Evaluate statement B: The receptive fields of touch receptors are uniform in area.
		Working: Receptive fields vary in size and density across different body areas.
		Key Point: Receptive field size is related to the need for fine discrimination.
	4. Evaluate statement C: The nociceptors of the skin are bare nerve endings.
		Working: This is correct. Nociceptors are free nerve endings that detect pain.
		Key Point: Bare nerve endings are characteristic of nociceptors.
	5. Evaluate statement D: All sensory information from the skin reaches the brain via the dorsal column pathway.
		Working: This is incorrect, the anterolateral pathway carries information about pain and temperature.
		Key Point: Different sensory pathways exist for different types of stimuli.
	6. Select the correct statement.
		Result: Option C is the only correct statement.
		Verification: Review of known physiological facts confirms the answer.
 ## OPTION ANALYSIS
[A] :x: Incorrect because not all skin receptors are encapsulated; free nerve endings exist.
[B] :x: Incorrect because receptive field size varies depending on location and receptor type.
[C] ✓: Correct; nociceptors are free nerve endings that detect pain.
[D] :x: Incorrect; pain and temperature information travel via the anterolateral pathway.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing different types of receptors:  Review the structure and function of each type (mechanoreceptors, nociceptors, thermoreceptors).
		2. Misunderstanding sensory pathways: Learn the specific pathways for touch, pain, and temperature.
	**Quick Tips**:
		1. Remember: Encapsulated receptors are generally mechanoreceptors.
		2. Visualize: Imagine free nerve endings as the 'bare' receptors for pain and temperature.
