Neuroanatomy — Flashcards

_____ are responsible for myelinating axons of neurons in the peripheral nervous system

The 1st-order neuron of the dorsal column-medial lemniscal tract synapses with a(n) _____-lateral nucleus cuneatus or nucleus gracilis

The axons of _____ganglionic sympathetic neurons enter the sympathetic trunk in white rami communicantes.

The neurites of the neurons constitute the _____ and the axon.

The _____-order neuron of the spinothalamic tract decussates at the anterior white commissure

Pre-ganglionic sympathetic neurons from _____ - L2 can bypass the sympathetic chain and synapse in prevertebral (pre-aortic) ganglia (splanchnic nerves)

The nerve to _____, branch of 3rd cranial nerve carries parasympathetic fibers to the ciliary ganglion.

Hint: muscle

The fasciculus _____ is the medial (medial or lateral) dorsal column

Layers _____ of the LGB receive the projections of the axons from the nasal retina of the contralateral eye (crossed fibres)

_____ visceral efferent column contains neurons innervating muscles developed from the pharyngeal arches: Motor nucleus of V nerve: innervating muscles of masticationMotor nucleus of VII nerve: innervating muscles of facial expressionNucleus ambiguus ( IX, X, XI): innervating stylopharyngeus, pharyngeal, external laryngeal and oesophageal striated muscles

Hint: G/S
