heart rate will get consistently lower. If too much alcohol is added‚ it will result in the death of the animal. The alcohol acts by inhibiting the nervous system. (LaFave‚ 2003) After an intoxicating exposure to alcohol‚ an organisms system will be impaired for an extended period of time. Caffeine is a stimulant. It will work by causing the nervous system to work faster. Also‚ it will cause the blood vessels to constrict. (LaFave‚ 2003) These effects will work together to increase an animals

junction‚ muscle membrane‚ and endoplasmic reticulum. The other one is the contractile mechanism‚ which is the muscle filament. A muscle fiber’s mechanical response declines with fatigue. Peripheral muscle fatigue is caused by changes in the internal conditions of the muscle. The changes can be biochemical‚ depletion of substrates‚ high-energy phosphate compounds in the muscle fibers‚ and acetylcholine in the terminal motor nerve branches‚ or they may be caused by the accumulation of metabolites.

2.2 Electrical Communication Study Guide by Hisrich 2.2.a How does communication happen within the body? Electrical Signals Nervous System Chemical Signals Endocrine System The nervous system is made up of neurons. Neurons communicate just like people do‚ but they send messages using action potentials (electricity passing through their axons). Each neuron picks up signals at its dendrites‚ passes the signals down the axon‚ into the axon terminals‚ and into the synapses. The synapse

It extends from the brainstem to the abdomen‚ with branches in the neck‚ thorax and abdomen 68. The vagus nerve is part of the autonomic nervous system‚ has efferent fibers‚ ascending signals from the brain to the peripheral organs‚ as well as afferent sensory fibers‚ and transmits information from the peripheral tissue to the brain. The ANS consists of three components: the sympathetic‚ noradrenergic

Physiology with Lab AMU Multiple Sclerosis A disease that affects the central nervous system (CNS) is known as Multiple Sclerosis (MS) and affects over 2.5 million people worldwide. Around 400‚000 people who have the disease reside in the United States. Of that 400‚000 the ratio is roughly one woman to every seven men. Multiple Sclerosis is a disease where the individual’s immune system attacks the central nervous system. The immune system attacks and damages the myelin sheath which is a coating

concept of art. Weitz argues that where previous theories go wrong is in their attempts to establish a set of necessary and sufficient condition of art‚ when in fact what we should do is ask about art the concept. Once this concept is understood‚ he argues that it will make clear the logical impossibility of defining art in terms of necessary and sufficient conditions. Furthermore‚ Weitz’s main argument for why theories of art fail comes from his application of Wittgenstein’s thoughts about language

HYPONATRAEMIA IN THE NEUROSURGICAL PATIENT INTRODUCTION Sodium the most abundant electrolyte in the human body‚ and therefore the osmolality of body fluids is strongly dependent on its concentration. Osmolality in turn is important in maintaining homeostasis within the brain. Ironically‚ dysfunction of the brain can cause changes in sodium homeostasis. To avoid neurological deterioration‚ morbidity or mortality the sodium level must be corrected promptly. The two most common causes of hyponatraemia
