Study Notes
Reflexes and Neural Pathways
- A reflex arc is a neural pathway that enables rapid, automatic responses to stimuli without the need for conscious thought or intentional action.
- The function of neural pathways is to transmit and process information from sensory receptors to the central nervous system (CNS) and then to effectors, which respond to the stimuli.
- Automatic responses and reflexes are closely related, as reflexes are a type of automatic response to specific stimuli, which occur via the reflex arc.
Key Characteristics of Reflexes
- Reflexes are involuntary, meaning they occur without conscious control or intention.
- Reflexes are rapid, occurring in a matter of milliseconds.
- Reflexes are specific, with a specific stimulus triggering a specific response.
- Reflexes involve a fixed, predetermined response, with little to no variation in the outcome.
