Brain and Neuroanatomy — Flashcards

The _____-order neuron of the dorsal column-medial lemniscal tract decussates in the caudal medulla

The _____ of the reticular formation is located in the posterior rostral pons and is responsible for synthesis of norepinephrine

The flexure between the _____ and the myelencephalon is called as the pontine flexure.

_____ motoneurons are always ipsi-lateral to the muscle they innervate

The dentate nucleus sends axons that decussate in the _____ and then synapse in the contralateral ventral lateral (VL) nucleus of the thalamus

At the superior end of the sulcus limitans, a bluish-gray area is produced by a cluster of nerve cells containing _____ pigment called substantia ferruginea

Within the ventral horn, alpha and gamma motoneurons that innervate _____ are located more ventrally

In accommodation reflex pathway, the afferent fibres from optic tract reach the _____ and finally end at the parastriate cortex

Rules of 4: Lesions in the brain stem that affect the _____ result in ipsi-lateral ataxia of the arm and leg

Wernicke-Korsakoff syndrome is characterized by:- damage _____laterally to the mammillary bodies - periventricular hemorrhagic lesions to the dorsomedial nucleus of the thalamus
