When a neuron is resting, the axonal membrane is comparatively:
1. More permeable to sodium ions than for potassium ions
2. More permeable to potassium ions than for sodium ions
3. Equally permeable for potassium and sodium ions
4. Impermeable to sodium and potassium ions

Nissl’s granules are seen in:
1. Only the cyton of the neuron
2. Only the axon of the neuron
3. Only in the cyton and dendrites of the neuron
4. In dendrites, cyton and axons of the neurons

A canal called the cerebral aqueduct passes through the:

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
