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