Afferent

Definition

Afferent refers to sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain. They play a crucial role in transmitting information about the body's internal and external environments.

5 Must Know Facts For Your Next Test

1. Afferent neurons are responsible for transmitting information related to touch, temperature, pain, and body position.
2. They are essential in initiating reflex actions by delivering sensory input to the central nervous system.
3. Proper nutrition can impact the function of afferent neurons, affecting overall neurological health.
4. Deficiencies in essential nutrients like B vitamins and omega-3 fatty acids can impair afferent neuron function.
5. Afferent pathways are critical in maintaining homeostasis by providing feedback to the brain about physiological conditions.
