Neuroanatomy — Flashcards

Post-ganglionic sympathetic and Pre-ganglionic parasympathetic neurons supplying the GI tract synapse in the _____ or submucosal plexuses

Injury to the _____ nerve presents as: 1. loss of forearm flexion and forearm supination (action) 2. loss of sensation over lateral forearm (sensation)

Hint: roots

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

Relations of otic ganglion:Superiorly - _____Laterally - Mandibular nerveMedially - Tensor veli palatiniPosteriorly - Middle meningeal artery

The axons of the _____ganglionic neurons are unmyelinated and return to the spinal nerve through the grey rami communicantes.

The smooth muscles of the eye and eyelid supplied by **sympathetic** innervation are the _____ and the Muller's muscle

Facial nerve course is horizontal in the _____ wall, vertical in the posterior wall

The artery of _____ supplies the lower two-thirds of the spinal cord.

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

_____ motor neuron lesions of the facial nerve result in contra-lateral paralysis of the lower muscles of facial expression
