Joint mechanoreceptors are found in all of the following structures except:

• A. Ligaments
• B. The brain
• C. Menisci
• D. Fat pads

Answer: (B)

Joint mechanoreceptors are specialized sensory receptors located in tissues around a joint that detect mechanical changes such as stretch, pressure, and movement, providing proprioceptive feedback to help coordinate movement and protect the joint. They are found in ligaments, where they monitor tension; in the menisci, adding information about load and joint congruence; and in fat pads, where they sense tissue deformation and pressure. These peripheral receptors send signals to the central nervous system to influence muscle activity and joint stability. The brain, while it processes and interprets these signals, is not itself a mechanoreceptor, so it does not contain joint mechanoreceptors.
