To solve the problem, we need to identify the nerves that carry impulses from sense organs to the brain or spinal cord.
1. Understanding the Types of Nerves:
- Dendrites: These are part of the neuron that receive signals from other neurons but do not carry impulses from sense organs to the brain or spinal cord.
- Afferent nerves: These are sensory nerves that carry impulses from sense organs to the brain or spinal cord. They are also called sensory nerves.
- Motor nerves: These nerves carry impulses from the brain or spinal cord to muscles and glands to produce an action.
- Efferent nerves: These nerves carry impulses away from the brain or spinal cord to the muscles or glands.
2. Identifying the Correct Answer:
The nerves that carry impulses from sense organs to the brain or spinal cord are called **Afferent nerves**.
Final Answer:
The correct answer is option (B): Afferent nerves.
S.No. | Cranial nerves | Arises from ... | Ends in ... |
---|---|---|---|
I. | Olfactory nerves | Olfactory epithelium of nasal chambers | Temporal lobes of cerebrum |
II. | Optic nerves | Retina of eyes | Cerebellum |
III. | Auditory nerves | Internal ears | Cerebrum |
IV. | Pathetic nerves | Floor of mid brain | Superior oblique muscle of eye ball |
