The Nervous System The nervous system is the most complex part of the body‚ as they govern our thoughts‚ feelings‚ and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease‚ stroke‚ accidents‚ etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

the body. It is made up of different kinds of neurons‚ which communicate with each other through electric signaling and neurotransmitters. There are two categories within the peripheral nervous system‚ known as the autonomic nervous system and the somatic nervous system. The autonomic nervous system is the part of the nervous system that regulates the involuntary activity of the heart‚ intestines‚ glands‚ digestion‚ respiration‚ perspiration‚ metabolism‚ and blood-pressure. This is then divided into

(Kowalski & Weston‚ 2011). The peripheral system is comprised of a network of neurons that act as a messenger to the central nervous system. Within the peripheral system is the somatic and autonomic nervous system. Each system contributes greatly to the overall function of the peripheral system as a whole. The somatic nervous system receives‚ processes‚ and sends information received from our basic senses to the central nervous system to then carry out motor functions in our bodies (Kowalski &

Differentiate between the autonomic and somatic nervous systems. The somatic nervous system is a body of peripheral nerve fibers that transport sensory information‚ and motor nerve fibers. The autonomic nervous system uses two neurons‚ and controls smooth muscle located in organs. 5. List the 3 types of neurons found

of prenatal alcohol exposure Introduction: Alcohol is a drug with a depressant effect. Alcohol can negatively affect your brain‚ liver‚ central nervous system‚ and heart. The immediate effects of alcohol consumption are delayed reflexes and slurred speech. Since it is a depressant‚ alcohol slows down your brain. Consuming alcohol regularly can also lead to alcoholism. Alcoholism is a long-term chronic disease‚ it is when you a mentally or physically addicted to alcohol. Alcohol

Parasympathetic VS Sympathetic The Autonomic Nervous System regulates cardiovascular‚ respiratory‚ digestive and urinary functions. The ANS studies have changed medicine practices. Before‚ the thought of a myocardial infarction patient living past five years was unheard of. Now doctors have learned to manipulate the ANS system with drugs that help to control blood pressure. The Autonomic Nervous System is composed of two divisions‚ Sympathetic and the parasympathetic divisions. They are involved
