A Novel Method For Analysis Of Proprioceptor Sensory Neuron Subtypes In The Mouse Dorsal Root Ganglia, Delaney C. Grant

Browse all Theses and Dissertations

Proprioceptive sensory neurons encode critical mechanosensory information that helps determine how the body interacts with the outside world and monitors the proper execution of motor movements. Housed in skeletal muscles lie specialized mechanoreceptors that are critical to this feedback loop: muscle spindles supplied by group Ia & group II afferents, and Golgi tendon organs supplied by group Ib afferents relay information regarding changes in muscle force, length, and tension. All three afferent subtypes originate in the muscle and travel to the dorsal root ganglia, relaying information to the central nervous system. GTO and MS proprioceptive afferent subtypes have been identified, …
