What Is Action Potential? |
|
Answer» When a stimulus is applied to a cell at the resting stage, there will be a high CONCENTRATION of the POSITIVE ions inside the cell. So there will be SLIGHTLY high potential on the inside of the cell due to imbalance of potassium ions. This is called ACTION potential.Range:20Mv. When a stimulus is applied to a cell at the resting stage, there will be a high concentration of the positive ions inside the cell. So there will be slightly high potential on the inside of the cell due to imbalance of potassium ions. This is called action potential.Range:20Mv. |

What Are Resting Potential? |
|
Answer» The MEMBRANE POTENTIAL measured when a equilibrium is reached with a potential difference across the cell membrane negative on the INSIDE and positive on the OUTSIDE is CALLED resting potential. The membrane potential measured when a equilibrium is reached with a potential difference across the cell membrane negative on the inside and positive on the outside is called resting potential. |

What Are Sensory Nerves, Motor Nerves And Mixed Nerves? |
|
Answer» The nerves that CARRY the information GATHERED by the sensory organs to the brain are called sensory nerves. They serve as MESSAGE carriers for the brain. Motor nerves carry back the orders from the brain to the muscles and glands. Mixed nerves PERFORM the function of the both sensory and motor nerves.

Define Relative Refractory Period (rrp)? |
|
Answer» ARP is FOLLOWED by RELATIVE refractory PERIOD. During this period, action POTENTIAL can be elicited by a super threshold STIMULUS. ARP is followed by relative refractory period. During this period, action potential can be elicited by a super threshold stimulus. |

Define Absolute Refractory Period (arp)? |
|
Answer» During the INITIAL portion of the action potential, the MEMBRANE cannot RESPOND to any stimulus, no MATTER how INTENSE the stimulus is. This interval is called ARP. During the initial portion of the action potential, the membrane cannot respond to any stimulus, no matter how intense the stimulus is. This interval is called ARP. |
