Neurology Flashcards
Where does ophthalmic nerve exit the cranium
The superior orbital fissure
The ophthalmic nerve divides into three branches
Frontal nerve
Lacrimal nerve
Nasociliary nerve
Branches of trigeminal nerve
Ophthalmic (V1)
Maxillary (V2)
Mandibular (V3)
Function of ophthalmic nerve
Provides sensory innervation to the skin, mucous membranes and sinuses of the upper face and scalp.
Nerves involved in corneal reflex
Ophthalmic nerve = the afferent limb – detecting the stimuli.
Facial nerve = efferent limb, causing contraction of the orbicularis oculi muscle.
What nerves may be damaged if corneal reflex is absent?
ttigeminal/ophthalmic nerve or the facial nerve.
Which structures pass through the jugular foramen?
Glossopharyngeal nerve (IX)
Accessory nerve (XI)
Vagus nerve (X)
What structures pass through the superior orbital fissure?
Oculomotor (III)
Trochlear nerves (IV)
Ophthalmic division of the trigeminal nerve (V)
Abducens nerve (VI)
The ophthalmic veins
What is Broca aphasia?
Non-fluent aphasia in which the output of spontaneous speech diminished + there is a loss of normal grammatical structure.
Small linking words, conjunctions (and, or, and but) are lost.
E.g. a person with Broca’s aphasia may say, “Walk dog,” meaning, “I will take the dog for a walk,” or “book book two table,” for “There are two books on the table.”
Function of parietal lobe
Responsible for integrating sensory information, including touch, temperature, pressure and pain.
The frontal lobe is separated from the parietal lobe by
The central sulcus
The frontal lobe is separated from temporal lobe by
The lateral fissure
Function of frontal lobe
Emotional regulation, planning, reasoning and problem solving
First signs of frontotemporal dementia
Personality changes
Where is the hippocampus located
In the temporal lobe
