D
In the skin and mucous membranes
Verified step by step guidance

Understand the role of sensory nerve endings: Sensory nerve endings are specialized structures that detect stimuli such as touch, temperature, pain, and pressure, and relay this information to the brain for processing.
Identify the primary locations of sensory nerve endings: Sensory nerve endings are most abundant in areas of the body that interact directly with the external environment, such as the skin and mucous membranes. These areas are designed to detect and respond to external stimuli effectively.
Eliminate incorrect options: Sensory nerve endings are not located in synovial fluid of joints, as this fluid primarily serves to lubricate and cushion joints. They are not found within red blood cells, as these cells are responsible for oxygen transport, nor are they located inside bones, which primarily provide structural support and house bone marrow.
Focus on the correct answer: The skin and mucous membranes are rich in sensory nerve endings because they serve as the body's first line of defense and interaction with the external environment, making them critical for detecting stimuli.
Conclude with the importance of sensory nerve endings: Their concentration in the skin and mucous membranes allows humans to perceive and respond to environmental changes, ensuring survival and protection from potential harm.
