b) 3
c) 2
d) 1
View Answer
Explanation: Optic lobes are present on dorsal side. 1 pair of an optic lobe is present. Each divided transversely into upper and larger superior coliculus and lower and smaller inferior colicus.
4. Optic lobes control visual reflexes.
a) True
b) False
View Answer
Explanation: Optic lobes control visual reflexes. It controls and coordinates the movement of head and eyes. It controls auditory refluxes also.
