Anti-seizure drugs that stop seizures from happening

 

Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited.

Anti-seizure drugs to stop seizures from happening

A seizure is a burst of uncontrolled electrical activity between brain cells (also called neurons or nerve cells) that causes temporary abnormalities in muscle tone or movements (stiffness, twitching or limpness), behaviors, sensations or states of awareness. Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. Sodium ion channels let in sodium ions when the threshold potential has been reached. This depolarizes the plasma membrane and starts the action potential. Calcium ion channels are found in axon terminals and they allow for the inflow of calcium ions which stimulate the release of neurotransmitters. When these channels are inhibited the ions cannot pass through them and therefore the processes they drive cannot occur.

his chapter is composed of nine parts. The background of the study, problem statement, theoretical framework, conceptual framework, research objectives, hypotheses of the study, significance of the study, scope and limitations, and definition of terms. The following will thoroughly explicate the significance of serious leisure qualities and economic index indicators in the Surf Resource Sustainability Index in choosing San Juan, La Union as a surf destination priority choice.

Background of the Study
During summer, both local and international tourists are thrilled to go under the sun to adore the white sands of the Philippines. The birth of surfing in the country is a great story that everyone should know. Baler is only known for fishing until the late 1970’s when the popular American film, Apocalypse Now, came to the Philippines to shoot. The movie starred Robert Duvali who plays Colonel Kilgroe, orders his men to ride the waves even though the surrounding is having a riot. While shooting the scene, a lot of locals were watching the shoot, they were amazed as the actors ride the big waves off-screen. After that, professional surfers extend their hand to teach surfing to the locals, but they always assure the safety of the locals (Conopio, 2013).
For almost 10 years the San Juan Beach is known for being the Surf Capital of the North in the Philippines because its waves are applicable for beginners, intermediate, and advanced surfers (Santos, 2013). The San Juan is bounded on the north by the municipality of Bacnotan along the Baroro River, and on the east by the municipalities of San Gabriel and Bagulin along the Dasay-Duplas-Nagyubuyuban Creek. On the south it is bounded by the City of San Fernando and on the west by the West Philippine Sea (San Juan La Union Government, 2014). The San Juan beach is six hours away from manila and it has a beautiful spot for surfing. It is the 4th longest coastline in the world with length of 36,289 km (Said, 2013).
