- 1—1 = BODY OF TONGUE
2 = CAVITY OF RIGHT MAXILLARY AIR SINUS
3 = VITREOUS BODY OF LEFT EYE
4 = CROSS SECTION OF RT OPTIC NERVE
5 = RT LAT RECTUS MM
Black arrows = sub-arachnoid space - 2—Dura mater = outer sheath
Arachnoid mater = intermed sheath
Pia mater = inner sheath
*Subarachnoid space*
Optic neuritis / papilloedema
- 3—1= R optic nn.
2 = L optic radiation
3 = Free edge, ant part tentorium cerebelli
4 = L ophthalmic division, Trigeminal nn. (CNV)
5 = L oculomotor nn. (CNIII)
6 = L eye, sup oblique mm.
7 = L ophthalmic artery
8 = R middle cerebral aa.
- 4—A = R pre-tectal nucleus
B = Right Edinger-Westphal bit of oculomotor nucleus
C = R oculomotor nerve exiting oculomotor nucleus
Damage to A and/or B results in absent pupillary consensual response in R eye
Damage to C results in failure to track a moving object - fixed dilated pupil.
- 5—Arrow = R oculomotor nn.
Pressure at this site would result in ipsilateral fixed dilated pupil
X = Choroid plexus in L lat ventricle. Produces CSF
- 6—X = One superior colliculus
R cerebral hemisphere
- 7—Calcarine sulcus
Primary visual cortex within sup and inf calcarine gyri
- 8—Left posterior cerebral artery
Loss of right visual field - i.e. half of the visual field in each eye - L eye central R eye periph vision defects
- 9—We are looking at a mirror image of the back of the eye within each visual field on a Goldmann perimeter plot
- 10—1. Limit of peripheral vision
2. Lesion R primary visual cortex, upper calcarine gyrus affecting left visual field
- 11—Represents the lateral sides of the nose
- 12—A = Cavity of frontal air sinus
B = Nasal cavity
C = Cavity of sphenoidal air sinus
D = Cavity of ethmoidal air sinuses
E = Pituitary gland
- 13—Red dots = L and R internal carotid aa.
Blue hatched area = Venous cavernous sinus
Brown dot = Pituitary
CNIII, IV, VI pass through the venous cavernous sinus
- 14—X = R internal carotid aa.
- 15—Dotted line = R optic radiation
Green line = Position of tentorium cerebelli
- 16—
- 17—
- 18—
- 19—
- 20—1. a = R cerebellum
1. b = Medulla oblongata
1. c = Pons
1. d = L temporal lobe
2. a = Insular cortex, R brain
2. b = Head of caudate nucleus, R brain
- 21—3. a = R ant cerebral artery
Cerebral aa lie in the subarachnoid space
4. a = L thalamus
4. b = Post limb R internal capsule
- 22—5. a = Midbrain
5. b = Corpus callosum
6. a = Third ventricle
6. b = R Lateral ventricle
CSF occupies ventricles. Produced by Choroid plexus (lat ventricles.)
- 23—A = cerebral aqueduct
B = 4th ventricle
- 24—A = Shingles (herpes zoster)
B = Rash occupies single dermatome as virus tyically infects single spinal nerve
- 25—A = myelin sheath
B = The largest fibres include sensory AND motor axons. The former woould be proprioceptive group I afferents and the latter would be axons of alpha motor neurons
- 26—A - unmyelinated axons
Either sensory (nociceptive or thermoreceptive) or autonomic axons
- 27—A - Motor neuron cell bodies
B - Exit ventral horn roots, join dorsal fibres from DRG to becomes spinal nerves
- 28—A = Lat corticospinal tract
B = Spinothalamic tract
- 29—13. A = IV disc L1/L2
B = Cauda equina
14. A = Right vertebral aa
B = Basilar aa
- 30—15. A = Falx cerebri
B = Sup sagittal sinus
16. A = Dura mater
B = Dorsal root ganglion
- 31—17. A = Symp trunk
B = Intercostal nn
18. A = Brachial plexus
B = Median nn
- 32—19. A = Sciatic nn L4/L5, S1/2/3
20. A = Vagus. Preganglionic paras. Slows heart rate
- 33—Left eye central and peripheral vision loss. Left optic nerve lesion
- 34—Left and right peripheral vision loss. Compression of optic chiasm i.e. pituitary tumour 'bitemporal hemianopia'
- 35—Right visual field loss aka right homonymous hemianopia. Left side lesion of the optic tract.
- 36—Right VF deficits - Right upper quadrantic hemianopia from lesion of lower fibres of optic radiation in left temporal lobe.
- 37—Right VF deficits, Lower right quadrantic hemianopia. Lesion in upper fibres of optic radiation in anterior part of parietal lobe. Left side.
- 38—Right visual field defects sparing the macula. Right homonymous hemianopia with sparing of macula due to lesion of optic radiation in occipital lobe.
