Read the following statements carefully: I. Unipolar neurons possess a cell body with one axon only and are typically found in the embryonic stage. II. Bipolar neurons possess one axon and two or more dendrites and are found in the cerebral cortex. III. Myelinated nerve fibres are commonly found in the autonomous and somatic neural systems. IV. Unmyelinated nerve fibres are enclosed by a Schwann cell that does not fo

Step-by-step solution

Statement I is correct: Unipolar neurons have a cell body with one axon only and are found usually in the embryonic stage. Statement II is incorrect: Bipolar neurons possess one axon and one dendrite and are found in the retina of the eye. Multipolar neurons possess one axon and two or more dendrites and are found in the cerebral cortex. Statement III is incorrect: Myelinated nerve fibres are found in spinal and cranial nerves. Unmyelinated nerve fibres are commonly found in the autonomous and somatic neural system
