Multiple Choice
Which of the following is a type of proprioceptor?
A
Pacinian corpuscle
B
Ruffini endings
C
Muscle spindle
D
Meissner's corpuscle
Verified step by step guidance
1
Understand the concept of proprioceptors: Proprioceptors are sensory receptors located in muscles, tendons, and joints that provide information about body position and movement to the central nervous system.
Identify the function of each option: Pacinian corpuscles detect pressure and vibration, Ruffini endings detect skin stretch, Meissner's corpuscles detect light touch, and muscle spindles detect changes in muscle length.
Recognize that muscle spindles are specifically involved in detecting changes in muscle length and tension, which is crucial for proprioception.
Differentiate between general mechanoreceptors and proprioceptors: While Pacinian corpuscles, Ruffini endings, and Meissner's corpuscles are mechanoreceptors, they are not primarily involved in proprioception.
Conclude that muscle spindles are the correct type of proprioceptor among the given options, as they provide sensory feedback about muscle stretch and position.
