Summary Introduction
To review:
The nuclei through which nerve impulses pass to reach their destination in the brain. Also, give the name of destination of impulses in the brain, which arises from the proprioceptors.
Introduction:
The central nervous system (CNS) contains a cluster of neurons that are present deep in the cerebral hemisphere and the brainstem. These clusters of neurons are called nuclei. The cells of these nuclei are associated with each other by the bundles of axon extension. Proprioceptor is a sensory receptor present that provides information about position and movement.

Students have asked these similar questions
Describe and draw the spinocerebellar pathway, dorsal column-medial lemniscal pathway, spinothalamic pathway, and the lateral (pyramidal) corticospinal pathway for the transmission of information associated with the right foot. What information is transmitted by each pathway? (All pathways should be clearly illustrated on the same figure. You may take a picture of your artwork and paste it into your word document.)
Which of the following statements about the basal nuclei are correct? (SELECT ALL THAT APPLY)
a.) The basal nuclei get information from only parts of the cerebral cortex that are involved in movement planning
b.) Parkinson's disease is a condition that affects the normal functioning of the basal nuclei
c.) The basal nuclei have an indirect pathway that tends to excite and thus increase the activity of the output nuclei (The Globus pallidus internal segment and substantia nigra pars reticulata) of the basal nuclei.
d.) The basal nuclei have a direct pathway that tends to inhibit and thus reduce the activity of the output nuclei (The Globus pallidus internal segment and substantia nigra pars reticulata) of the basal nuclei.
Imagine you are walking and encounter an unexpected change in ground elevation and you begin to stumble. In order to recover your balance, what components of the nervous systems would be most significantly involved?
a.) Cerebrum and corticospinal tracts
b.) Primary motor cortex and corticospinal tracts
c.) Cerebellum and vestibulospinal tracts
d.) Sensory cortex and somatosensory tracts
