Q27 / 244 · NTA Abhyas (NEET) 2020 · Zoology · Neural Control and Coordination

Select the incorrect statement.

  • A
    The cerebral hemispheres are connected by a tract of nerve fibres called the corpus callosum.
  • B
    The cerebrum wraps around a structure called thalamus, which is a major coordinating centre for sensory and motor signaling.
  • C
    The hypothalamus contains a number of centres which control body temperature, urge for eating and drinking.
  • Correct answer
    D
    The cerebral cortex contains motor areas, sensory areas and large regions that are both sensory and motor in function.

Solution

The cerebral cortex contains motor areas, sensory areas and large regions that are neither clearly sensory nor motor in function. These regions called as the association areas are responsible for complex functions like intersensory associations, memory and communication.

Hence, the correct answer is option: 'D'.
