| Which brainstem nuclei send information to the Left cerebellum? | ?L.lateral cuneate; reticular; mesencephalic |
| Which nuclei send proprioceptive information from the head to the cerebellum? | Mesencephalic and reticular |
| Give the location of the nerve cell bodies for each of the following fibers: Right ventral posterior medial nucleus of the thalamus | ?Left sensory nucleus V, Left spinotrigeminal nucleus, Left reticulate nucleus |
| give the source of afferents to non-specific group of thalamic nuclei: C) in the pathway for reticular activation | reticular nuclei of brainstem ?ventral trigeminal, paleospinothalamic |
| which thalamic group of nuclei receive afferents from both the paleospinothalamic tract and the reticular nuclei of the brainstem? | diffuse reticular projection group |
| name the nuclei whose fibers join the inferior cerebellar peduncle | ?lateral cuneate; nucleus dorsalis,lateral lemniscus; reticular nuclei of brainstem |
| name the nuclei/grey whose fibers join the right inferior cerebellar peduncle | ?R lateral cuneate, R dorsal nucleus, reticular nuclei |
| Name the projection group of thalamus which: Projects to the prefrontal cortex and the cingulated gyrus; receives information from the spinothalamic tract, ventral trigeminothalamic tract and reticular nuclei of the brainstem | ?Nonspecific Group |
| Name the sources of afferents to reticular nuclei which are most important for stimulation of the lower motor neuron. | ?paleospinothalamic, spinoreticular, ventral trigeminothalamic, mesencephalic |
| Name the thalamic nuclei described. Belongs to the specific group, Projects to area 17, Receives afferents from sensory association cortices, receives afferents from reticular nuclei involved in reticular activation. anterior, intralaminar and posterior | ?Integrative Nuclei of Thalamus: Pulvinar, Lateral Posterior, Lateral Dorsal |
| Of the 4 major sources of information into reticular nuclei of the brainstem, which are relayed to the lower motor neurons? | ?Hypothalamus relays to Endocrine and Autonomics |
| In general, reticular nuclei of the reticular activating system receive afferents from _____ | general sensory, cerebral cortex, cerebellum, hypothalamus |
| in general, reticular nuclei which are part of the ascending reticular activation system (ARAS) receive input from which 2 sources | General sensory and cerebral cortex |
| name the 2 major general sources of afferents to the reticular nuclei in the pathway for ascending reticular activation? | sensation, cerebral cortex |
| In general, the reticular nuclei of the brainstem receive input from all sensation, the cerebral cortex, the ______, and the ________. | Hypothalamus, and cerebellum |
| in the ascending reticular activating system, reticular nuclei receive afferents from the cortex and all sensory systems. In turn, these reticular nuclei project to the hypothalamus and ___ | non-specific and limbic nuclei of thalamus |
| name the general sensory tracts which terminate ( at least in part) on the reticular nuclei of the brainstem (omit fibers from the mesencephalic nucleus) | ventral trigeminothalamic, paleospinothalamic, spinoreticular |
