it is actually called a "spinal reflex" and is sensed and processed by the spinal chord which sends out a motor message. that's how we move our hand away without actually feeling the heat or pain as it doesn't go as far as the brain
The withdrawal of the hand from the hot stove triggers a pain signal to be sent from the nerves in the hand to the brain, which is perceived as pain. This pain signal needs time to travel to the brain and be processed before the student can react by yelling. So, the yelling occurs after the hand is withdrawn due to the processing time of the pain signal in the brain.
This involves your nervous and muscular systems. When you tough the hot pan, a sensory neuron (nerve cell) will send a message to your central nervous system, which will relay the message through a motor neuron to your muscles to then contract your muscles and pull your hand off the hot stove.
You would not be able to feel anything so if you put your hand on a hot stove you wouldn't feel it but you would burn yourself badly, and you wouldn't have the reflex that the sensory neurons give you to pull your hand away quickly once you come in contact with heat.Elena
Reflex reactions, such as pulling your hand away from a hot stove or blinking when something comes close to your eye, do not require conscious thought and therefore do not involve the brain. These reactions are coordinated by the spinal cord or peripheral nerves.
If the nerves in your hand were completely destroyed, you would likely lose sensation and motor function in that hand. This could result in numbness, inability to feel pain or touch, and difficulty in controlling movement in the affected hand. Physical therapy or surgery may be needed to improve function.
nervouse system
Because the heat from the stove rises to your hand and makes your hand hotter.
In the nervous system you can smell,feel,hear,hurt,laugh,see and many other things. Soif you want a good fact it would probably be the reason we hove the nervous system is because if we put our hand on a stove we wouldn't know and your hand would probably so burnt it will get to the point where youll have to cut it off.
When an individual touches a hot stove, the nervous system responds immediately by sending sensory signals from the skin to the spinal cord and brain, triggering a reflex action to withdraw the hand quickly. Simultaneously, the endocrine system may release adrenaline (epinephrine) from the adrenal glands, which prepares the body for a "fight or flight" response, increasing heart rate and enhancing alertness. This coordinated response helps protect the body from injury and prepares it to react to potential danger.
No that is just a hand over the stove. If the stove element is turned on and you place your hand close to the element you will feel heat. This is heat radiation, the same as when you feel the heat from the sun, also heat radiation.
The function of the nervouse system is to feel (touch), or feeling pain in the body. Skin, Hair, Nails. The functions of the nervouse system is to carry messages to and from the brain, spinal cord, and all other parts of the body.The nervous system tells the body how to respond to the environment for example: when you put your hand on the stove the brain sends a message through your nervs so that you can feel the burn and get your hand off the stove.
The reflex action of burning your hand would be jerking your hand away from the source of the heat
When you jerk your hand away from a hot stove, you are activating your body's reflex arc. This involves sensory neurons detecting the heat and sending a signal to your spinal cord. The spinal cord then sends a signal to your muscle cells, causing them to contract and move your hand away from the source of heat without conscious thought.
It is the nervous system that signals you that something is wrong when you touch a hot stove. Nerve receptors in your skin detect the heat and send rapid signals to your brain, which then interprets this as pain, prompting you to withdraw your hand. The endocrine system mainly controls hormone release and does not directly respond to immediate dangers like touching a hot stove.
An example of conduction is when you touch a hot stove and feel the heat transferring from the stove to your hand.
The heat you feel when you touch a hot stove is conducted heat, which occurs when your hand comes into direct contact with the hot surface of the stove. Heat energy transfers from the stove to your hand through the process of conduction.
they would react to it
