<u>Neurons</u>, the main cells of the nervous system, <u>have a charged cellular membrane</u>.
Neurons communicate with each other by the transmission (sending and receiving) of electric signals called action potentials.
When a neuron is not communicating, we say it's at rest. <u>The resting membrane potential of neurons is negative on the inside</u>.
When neurons communicate, their membranes' charges change in response to external molecules. For this to happen, a neuron's membrane has "gates" to allow charged molecules (ions) enter and exit the cell. These gates are called ion channels.
<u>When positively charged ions enter the cell, depolarization happens</u>, decreasing the difference in voltage between the inside and outside of the cell membrane; the interior becomes less negative. This is how action potentials are generated.
For an action potential to happen, a neuron most receive a stimulus that starts depolarization of its membrane, once a specific threshold is reached (enough positive ions have entered), then there's no turning point and an action potential is generated, causing depolarization of the membrane. Then positive ions start leaving the cell causing a repolarization of its membrane, before it goes back to resting potential.
When negatively charged ions enter the cell, hyperpolarization happens, increasing the difference in voltage between the inside and outside of the cell membrane; the interior becomes even more negative than at resting potential.
Chloride is a negatively charged ion, so when it enters a neuron via its chloride channels, the membrane potential will become more negative than when it was at rest, causing hyperpolarization of the membrane.
The consequence of this hyperpolarization is inhibition of action potential generation, which means that the neuron can't communicate. This is because the inside of the cell is too negatively charged for it to be able to easily reach the action potential threshold.
Inflammation or irritation of a tendon tissue that connects muscle to bone Arthritis – Painful inflammation and stiffness of the joints. Carpal Tunnel – Irritation of the median nerve which causes tingling and numbness of the thumb, index, and the middle fingers.
A second degree burn is the middle step in burn severity, and needs some medical treatment. A second degree burn penetrates deeper layers of skin than a first degree burn, which results in the skin releasing liquid and the formation of blisters.
Well lets start with this, Carbon Monoxide hinders the ability to distribute oxygen throughout your body and in the body of someone who smokes carbon monoxide passe will pass through the lining of the Lung into their blood, where it can attach to red blood cells.
