**Control of Reflex Action**
**The Spinal Cord:**
- Reflex actions are controlled by the spinal cord.
- When a stimulus is detected by sensory receptors, the information is quickly sent to the spinal cord.
**Role of the Spinal Cord:**
- The spinal cord processes the information and sends a response to the muscles to react.
- This process bypasses the brain in order to produce a quick response.
**Advantages of Spinal Cord Control:**
- By having reflex actions controlled by the spinal cord, the body is able to respond rapidly to potential harm.
- This quick response can help prevent injuries or further damage.
**Role in Survival:**
- Reflex actions controlled by the spinal cord are crucial for survival, as they allow for immediate reactions to danger without needing to wait for signals to travel to and from the brain.
**Conclusion:**
In conclusion, reflex actions are controlled by the spinal cord due to its ability to quickly process information and send responses to muscles. This system allows for rapid reactions to potential harm, ultimately aiding in the body's survival.

Control of Reflex Action
- Muscles: Muscles play a role in reflex actions by contracting or relaxing in response to a stimulus.
- Limbs: Limbs are involved in carrying out the reflex action, such as moving away from a painful stimulus.
- The Spinal Chord: The spinal cord plays a crucial role in controlling reflex actions. When a stimulus is detected, sensory neurons in the skin or other sensory organs send signals to the spinal cord. The spinal cord then processes this information and sends signals back through motor neurons to carry out the appropriate response, all without involving the brain. This quick response is essential for survival in potentially dangerous situations.
- Autonomic Nervous System: The autonomic nervous system controls involuntary actions, such as heartbeat and digestion, but not reflex actions. Reflex actions are typically controlled by the spinal cord to allow for quick responses without the need for conscious thought.
