Examples of Newton's 2nd Law, If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass. It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one.
When Timmy steps on the rose bush, the sensory receptor on his toe receives the stimuli, sends it the spinal cord through a sensory neuron which they initiates a response sent through a motor neuron to the muscle and he withdraws his leg in pain.
<h3>What is a reflex arc?</h3>
A reflex arc refers to the neuronal pathway which controls a reflex action.
A reflex action is an action which occurs involuntarily.
Examples of reflex actions include thhe following:
- withdrawing the foot quickly when one steps on a sharp object
- withdrawing the hand quickly when one touches a hot surface
- the je_rking of the knee
- coughing or sneezing, when irritants enter the nostrils.
Reflex actions do not need to involve the brain, hence they occur very quickly.
The path of a reflex arc begins with a sensory receptor which receives the stimuli, travels to the spinal cord through a sensory neuron which they initiates a response that is sent through a motor neuron to an effector such effector such as a skeletal muscle.
In conclusion, a reflex arc is the path of a reflex action through the body.
