Neuroanatomy — Flashcards

The cell bodies of the _____ganglionic sympathetic neurons are located in the lateral horn in the spinal grey matter.

Syringomyelia results in damage to the _____ tract 2nd-order neurons crossing in the anterior white commissure

The neurons present in the lamina _____ of the grey matter in spinal segments S2, S3, and S4 constitute the Onuf's nucleus which helps contract the external urethral sphincter.

Foramen of the skull:The _____ nerve, a branch of facial nerve carries the preganglionic parasympathetic fibres to the pterygopalatine ganglion

The axons of _____ ganglionic sympathetic neurons are lightly myelinated and leave the cord in the ventral nerve roots to form spinal nerves

The _____ reflex tests nerve roots S3 and S4

The _____ branch of the great auricular nerve supplies the facial skin over the parotid gland and joins the facial nerve in the gland.

_____ visceral efferent fibres of the facial nerve carry motor fibres to muscles of facial expression

Hint: General/Special

The 1st-order neuron of the spinothalamic tract synapses with an _____-lateral cell body in the dorsal horn of the spinal cord

_____ cord: Formed by all 3 posterior divisions
