Q

Significance of these structures going through the cavernous sinus

A

22
Q

Function of ciliary ganglion

A

Eye accommodation

23
Q

Pterygopalatine ganglion nerve

A

Greater petrosal nerve: facial nerve

24
Q

Function of pterygopalatine ganglion function

A

Innervation of

Lacrimal gland, mucous glands of nasal cavity, maxillary sinus and palate

25
Otic ganglion nerve
lesser petrosal nerve of CN9
26
Otic ganglion function
Innervation of parotid gland
27
Submandibular ganglion nerve
chorda tympani to lingual (CN7)
28
Function of submandibular ganglion
innervation of submandibular and sublingual glands
29
Clinical finding in oculomotor palsy
Dilated pupil Eye go down and out
30
Clinical findings in trochlear palsy
Eyes cant look down and in cant look downstairs
31
Gross anatomy of saggital section of brain
thalamus surrounds 3rd ventricle Mamillary bodies inferior surface of hypothalamus
32
Which part of cortex responsible for sensory/motor
Precentral gyrus motor Post central gyrus sensory
33
Position of Brocca vs Wernicke's areas
Brocca- expressive speech, frontal lobe : Brodman area 44,45 Wernickes- receptive speech, temporal lobe: Brodman area 22
34
Hypothalamus anatomy
pituitary attached inferiorly by infundibulum (pituitary stalk) mamillary bodies anterior floor of 3rd ventricle
35
Which cranial nerve doesnt originate from brainstem
CN11 Forms from roots of top 5 cervical spine Goes up through foramen magnum Comes down through Internal jugular foramen
36
Course of vertebral artery
Originates at subclavian Climbs up between anterior scalene and longus coli Enters transverse foramen of C6 → C1 Goes along the posterior arch of C1 to enter skull through foramen magnum Joins the other side in front of medulla oblongata to become basilar artery
37
Course of CSF from lateral ventricles
Lateral V – Foramen of munro → 3rd V 3rd V – Aqueduct of Sylvius → 4th V – foramen magendie (medial-posterior) → subarachnoid space – foramen Luschka (lateral-anterior) → subarachnoid space
38
Gyri vs sulci
Gyrus: raised parts of cortex Sulcus: groove between two gyri
39
What forms white and grey matter
Grey matter: * neural cell bodies * More superficial * Processing information White matter: * Axons * Deeper
40
Superficial cerebral fissures
Fissure: deeper sulcus, mainly used interchangeably Longitudinal (between frontal lobes) Sylvius (between temporal and fronto-parietal) Rolando (between frontal and parietal)
41
Where is the Calcarine sulcus
Deep fissure separating occipital lobe into lingual (inferior) and cuneus (superior) gyri Visual cortex lies either side of this sulcus
42
Branches of vagus nerve
7: Meningeal (sensory to dura in posterior cranial fossa) Auricular Pharyngeal plexus Superior laryngeal Recurrent laryngeal Carotid sinus PSN to thorax and abdomen
43
Origin of cranial nerves
CN1 and 2: nuclei in forebrain CN3-4: Midbrain CN5: Pons CN6-8: Pons/Medulla junction CN9-11: Medulla CN12: cervical spine
44
Cerebellar anatomy
Vermis: midline section (associated with locomotion) Vallecula: the gap at the bottom of the cerebellum where vermis disappears
45
Function of basal ganglia
Co-ordinates movement
46
Nuclei of basal ganglia
Located at the base of cerebral hemispheres Caudate nucleus Putamen Globus pallidus Substantia nigra Subthalamic
47
Extradural vs subdural haemorrhage causes
Extra: cerebral artery eg middle meningeal Subdural: cerebral veins draining into venous sinuses
48
Extradural vs subdural on CT
Extra: lens like Subdural: crescent like
