Afferent nerve fibres are sensory nerve fibres that carry sensory information from receptors (e.g., in skin, eyes, ears) to the central nervous system (CNS). Conversely, efferent nerve fibres carry motor commands from the CNS to muscles or glands (effectors).

Afferent Nerve Fibres Overview
Afferent nerve fibres play a crucial role in the functioning of the nervous system. They are responsible for transmitting sensory information from various parts of the body to the Central Nervous System (CNS).
Function of Afferent Nerve Fibres
- Direction of Impulse: Afferent fibres carry impulses from receptors located in sensory organs (like skin, eyes, ears, etc.) directly to the brain and spinal cord, which are components of the CNS.
- Sensory Information Processing: This information allows the CNS to process sensory input, enabling perception, reflexes, and appropriate responses to environmental stimuli.
Contrast with Efferent Nerve Fibres
- Efferent Nerve Fibres: Unlike afferent fibres, efferent fibres transmit signals from the CNS to effector organs, such as muscles and glands, facilitating action and response.
Importance in the Nervous System
- Homeostasis and Response: Afferent nerve fibres are essential for maintaining homeostasis as they provide critical feedback about the body’s internal and external environments.
- Reflex Actions: In reflex actions, afferent fibres quickly send signals to the CNS, which then generates a response through efferent fibres, often without conscious thought.
In summary, the correct answer to the question is option 'B', as afferent nerve fibres specifically carry impulses from receptors to the CNS, which is pivotal for sensory perception and response mechanisms within the body.
