This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Ophthalmology
The visual pathway consists of all of these except -a) Optic tractb) Geniculocalcarine tractc) Inferior colliculusd) Lateral geniculate bodye) Pretectal region 
Select and explain. 
A. a, B. b, C. ac, D. ce
D: ce
Answer: D: ce 
Explanation: The visual pathway starting from retina consists of optic nerve, optic chiasma, optic tracts, lateral geniculate bodies, optic radiations (geniculocalcarine pathway), the visual cortex, in that sequence.
It should also be kept in mind that some fibres from optic radiation go to -


Superior colliculus → involved in visual reflexes
Pretectal nucleus → involved in visual reflexes
Suprachiasmatic nucleus concerned with circadian rhythms


However, these structures are not part of visual pathway, which is mainly concerned with the vision.
