A canal called the cerebral aqueduct passes through the:

1. Cerebral hemispheres	2. Diencephalon
3. Mid brain	4. Hind brain

From outside to inside, the correct sequence of cells in the inner layer of human retina will be:

2. Ganglion cells, Bipolar cells, Photoreceptor cells
3. Photoreceptor cells, Ganglion cells, Bipolar cells
4. Ganglion cells, Photoreceptor cells, Bipolar cells

The myelin sheath around the axons is secreted in the CNS by:
1. Schwann cells
2. Oligidendrocytes
3. Microglial cells
4. Astrocytes

Gustatory receptors are meant for:

In the ear, the utricle and the saccule are located in the:

Fovea centralis is a part of:

The major refractive surface in the human eye is the:
1. Anterior surface of cornea
2. Posterior surface of cornea
3. Anterior surface of lens
4. Posterior surface of lens

When the ciliary muscles in the human eye contract:
1. the lens becomes more convex, generally improving the focus for closer objects
2. the lens becomes more convex, generally improving the focus for farther objects
3. the lens becomes more flat, generally improving the focus for closer objects
4. the lens becomes more flat, generally improving the focus for farther objects

The afferent neuron receives signal from a sensory organ and transmits the impulse to the CNS via:
1. Dorsal root of the spinal nerve
2. Ventral root of the spinal nerve
3. Cranial nerve
4. Intermediolateral horn of spinal cord grey mater

If potassium ions were the only factor causing resting membrane potential, the resting potential inside the fiber would be nearly equal to:
