Answer:
The reflex arc follows this sequence of events
1. sensory receptor activation
2. sensory neuron activation
3.information processing
4. motor neuron activation
5. effector response
Explanation:
Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.
According to G.D Budhiraja in his book "The Natural Way of Healthy Aging," the ultimate wonder of cells is the egg cell.
The egg cells is considered to be the ultimate wonder of cells because of its potential to form another human being. Once fertilized, the egg cell multiplies and grows, and "seems to know" just the right timing for certain processes to occur within the embryo or fetus. It seems to know when certain hormones should be produced, when it should implant in the uterus, and when the hands, legs, feet, hair, and other parts of the embryo and fetus should grow.
Answer:
The leak channels allow Na+ and K+ to move across the cell membrane down their gradients (from a high concentration toward a lower concentration). With the combined ion pumping and leakage of ions, the cell can maintain a stable resting membrane potential.
