Neuroanatomy — Flashcards

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

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

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

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

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

Contents of superior orbital fissure (within the common tendinous ring): - _____ - Abducens nerve - Nasociliary nerve (Mnemonic: BAN)

Most (80-90%) of the corticospinal tract fibers decussate just below the _____ at the pyramidal decussation

The fasciculus _____ carries input from the spinal level T6 and above

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

Rules of 4: There are four _____ structures that start with 'M'1. Motor pathway (corticospinal tract)2. Medial lemniscus 3. Medial longitudinal fasciculus (MLF) 4. Motor nuclei/nerves (CN III, IV, VI, XII)
