  • Question 1
    1 / -0
    Which is odd one?
    Solution
    Arachnoid, Duramater, Piamater are layers of meninges while the choroid pexus is a network of blood vessels in each ventricle of the brain, producing the cerebrospinal fluid.
    Hence, the correct answer is (D)
  • Question 2
    1 / -0
    Roof of cerebrum is called
    Solution

    The pallium is a thick layer of the grey matter that forms the dorsal surface of the cerebrum and covers the paracoel (the lateral ventricles) like a roof.  It is highly developed in the brains of both the humans and rabbits. Paracoel is the cavity or the ventricle that is found in the cerebral cortex. It is also called the 2nd ventricle. The 1st ventricle is the rhinocoel. It is the cavity of the olfactory lobe. The cavity of the diencephalon is called the 3rd ventricle or the diocoel. The 4th ventricle is the cavity in the brain stem.
    Hence, the correct answer is (A)

  • Question 3
    1 / -0
    Cerebrum is in direct contact with
    Solution
    • Inside the skull, the brain is covered by cranial meninges consisting of an outer layer called duramater, a very thin middle layer called arachnoid and an inner layer (which is in contact with the brain tissue) called piamatar.
    Hence, the correct option is (C)
  • Question 4
    1 / -0
    Medulla oblongata contains centres which control
    Solution
    The medulla contains the cardiac, respiratory, vomiting and vasomotor centers and therefore deals with the autonomic functions of breathing, heart rate and blood pressure as well as the sleep wake cycle. During embryonic development the medulla oblongata develops from the myelencephalon.
    So, the correct answer is (D)
  • Question 5
    1 / -0
    Nasal epithelium is formed of
    Solution
    Nasal epithelium lies in the roof of nostril. It is pseudostratified epithelium which is composed of olfactory sensory neurons. The neurons are bipolar neurons having dendritic knobs that bear olfactory receptors. Pseudostratified epithelium means a single layer of cells. More appropriately, the nasal epithelium is pseudostratified columnar ciliated epithelium as the cells are columnar and have cilia projecting from the surface of cells.
     So, the correct answer is 'Pseudostratified epithelium'.
  • Question 6
    1 / -0
    Right and left cerebral hemispheres are linked by a broad nerve band called
    Solution
    The Corpus callosum is a thick band of neural fibres connecting the right and left cerebral hemisphere. It allows the two hemispheres to communicate with each other and information to be processed and shared with the other side. Thus the answer is A.
  • Question 7
    1 / -0
    The parietal and temporal lobes are separated by ?
    Solution
    Central sulcus separates frontal and parietal lobe, whereas the lateral sulcus separates temporal lobe from frontal and parietal lobe. So the answer is C.
  • Question 8
    1 / -0
    Identify at least two labels from a d of human brain in sagittal section

  • Question 9
    1 / -0
    Activities like running, talking and typing are controlled by _______.
  • Question 10
    1 / -0
    Temporal lobe of cerebrum is concerned with detection of the following sensations except _________.
