13.
Regarding the ciliary ganglion
a.
contains sympathetic fibres from the upper cervical
trunks
F
b.
Cell bodies in superior cervical ganglion
? – could be true
c.
Receives branches from lingual nerve
F
d.
Something about CN VII
NOTE: Some notes on the ciliary ganglion: 2mm diam, lies on the lateral side of
the optic nerve. Three roots enter its posterior end
1. Sensory root from nasociliary nerve passes through
without
relay to suuply
eye but not the conjunctiva
2. Sympathetic root from the internal carotid plexus passes through
without
relay supplying ciliary body carrying vasoconstrictor supply to vessels of the eye
3. Parasymp root from EW nucleus RELAY in the ganglion going to ciliary body
for accommodation and sphincter pupillae
14.
A Horners syndrome can result from interruption of all
tract/areas except
a.
T1 something
b.
Brainstem
c.
Post-sympathetic fibres
15.
Regarding the CNS
a.
The tentorium cerebelli separates the right and left
halves of the cerebellum
F - it forms the roof (p911 Moore), falx separates R from L
b.
The temporal lobe occupies the middle cranial fossa
T
c.
The falx cerebri separates the occipital lobes from the
cerebellum
F - separates R from L cerebral hemispheres
d.
Central sulcus separates occipital from parietal lobes
F - separates frontal from parietal
e.
Occipital lobe is posterior to the lateral sulcus
F - occipital separated from parietal by occipito-parietal sulcus
•
Anterior fossa
-
Formed by frontal bone anteriorly, ethmoid in the middle, sphenoid post
-
Contains Frontal lobes
•
Middle fossa
-
Formed by sella turcica of sphenoid plus lateral parts
-
Contains pituitary,lateral parts support the temporal lobes
•
Posterior fossa
-
Formed mostly by occipital bone
-
Contains cerebellum, pons, and medulla
