antibodies that block acetylcholine receptors at the neuromuscular junction. This prevents nerve impulses from triggering muscle contractions. The most commonly affected muscles are those of the eyes‚ face‚ and swallowing. It can result in double vision‚ dropping eye leads‚ trouble talking‚ and trouble walking. Diagnosis can be supported by blood tests for specific antibodies‚ the edrophonium test‚ or nerve conduction studies. The anti–acetylcholine receptor antibody test is reliable for diagnosing autoimmune

In contrast to this‚ social media is not being considered as new way to do marketing but it has been integrated as a marketing strategy in the conduction of businesses today. This is to the extent that the use of social media in businesses today is being considered to be an evolution rather than a revolution. Although the traditional marketing strategies such as referrals‚ advertizing and public

Fleas are very small insects. They are all flightless and do not have eyes‚ although two ocelli may be present. Their antennaes are short and their mouthparts are adapted for piercing and sucking. The female flea lays a few eggs daily that total up to 300 to 400 in its lifetime. The eggs are laid usually on animals and most drop off where they spend most of their time. Bedding‚ floor crevices‚ carpeting‚ along baseboards and areas near their favorite sleeping and napping sites are especially likely

Essential fatty acids are vitally important for muscle conduction‚ nerve impulses‚ and brain health but our bodies do not make these fatty acids on their own we have to consume them through our diet. The two major essential fatty acids or EFA’s are omega 3 and omega 6. The typical modern diet is far too abundant in omega

THE THREE LAWS OF MOTION BY ISAAC NEWTON NEWTON’S FIRST LAW OF MOTION: INERTIA 2 Kinds of Inertia Inertia on Rest- an object will remain at rest‚ unless there is force applied to move Inertia on Motion- a moving object will continue to move unless there is force applied to stop Projectiles persevere in their motions‚ so far as they are not retarded by the resistance of the air‚ or impelled downwards by the force of gravity.

tissues in the body. The functions of nerve tissue are to receive stimuli‚ transmit stimuli to nervous centers‚ and to initiate response. The central nervous system consists of the brain and spinal cord and serves as the collection point of nerve impulses. The peripheral nervous system includes all nerves not in the brain or spinal cord and connects all parts of the body to the central nervous system. The somatic nervous system controls functions that are under conscious voluntary control such as

Sinoatrial (SA) node in the right atrium and the Atrioventricular (AV) node in the interatrial septum. The electrical signals move through the cardiac conduction system fibres causing the atria and ventricles to contract and relax regularly between 60-100 bpm [1].when those electrical signals are interrupted as a result of a damage in the conduction system‚ the heart rate would become irregular or would either increase resulting in Tachycardia condition or decrease resulting in Bradycardia [2] as

Internal Structure of the Stem The internal structure of the stem is usually more complex than the other plant organs for it performs and provides various functions. These functions are: * For mechanical support * For conduction of water * For conduction and storage of manufactured food * For continuous growth of the stem in thickness These functions are centered at the fibro vascular system that is composed of two major tissues‚ the xylem and the phloem.

At room temperature‚ T is about 300 K‚ the gap is so wide that electrons energy level cannot leap from Fermi level to conduction levels. However‚ this situation only happens for the topological insulator’s interior. For surface parts‚ their band structures are much different and behaves as metallic

INTRODUCTION The word "anesthesia"‚ coined by Oliver Wendell Holmes‚ Sr. (1809–1894) in 1846 from the Greek αν-‚ an-‚ "without"; and aisthēsis‚ "sensation")‚ refers to the inhibition of sensation. An anesthetic (American English) (or anaesthetic‚ (Commonwealth English)) is a drug that causes anesthesia—reversible loss of sensation. They contrast with analgesics (painkillers)‚ which relieve pain without eliminating sensation. These drugs are generally administered to facilitate surgery. A wide
