Flashcards in Anatomy and auditory and visual pathways Deck (12):
1
Where can the cochlear nuclei be found?
Ventrally and dorsally on either side of the inferior cerebellar peducle
2
What is the pathway of auditory neurones?
Vestibulococochlear nerve - spiral ganglion
Doral and ventral cochlear nuclei
Superior olivary nucles
Inferior colliculus (midbrain)
Medial geniculate nucleus in thalamus
Primary auditory cortex of the superior temporal gyrus; brodmanns area 41 and 42
3
Do auditory fibres run in the internal capsule?
Yes
4
What occurs with damage to broca's area?
Difficulty in production of language, often using few words and only saying the most important things in a sentence
No difficult comprehending language
5
What occurs with damage to wenicke's area?
Difficult comprehending language. Conversation will have words out of order or be complete gibberish
6
Where is brocas area?
Frontal lobe
7
Where is wernickes area?
Temporal lobe
8
What systems does equilibrium maintenance rely on?
Vision
Proprioception
Vestibular apparatus - labyrinth
9
How many vestibular ganglia are there?
4
10
What is the significance of the medial longitudinal fasciculus?
Connection from vestibular nuclei to CN 3,4 and 6 to coordinate eye movement with head position - Vestibulo-ocular reflex
11
