(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 &

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

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

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

What is the difference between hypo-reflexive and hyper-reflexive responses? (What do these indicate?) Hyperflexia is defined as an increased action of the reflexes.1 Hyperflexia (exaggerated response) results from damaged or diseased motor areas in the CNS.2Hypoflexia is defined as a diminished function of the reflexes.

Parasympathetic Dominants often use sleep to overcome energy losses following periods of sustained alertness. The Autonomic Nervous System • The sympathetic branch of the autonomic nervous system is responsible for functions that require focus and decision making. It’s the branch that speeds up when you need to go fast. It goes into high gear when an emergency situation requires quick thinking and reflexes‚ spurts of energy‚ hyper vigilance‚ and rapid heart rate - a need to “fight or flee fast”‚ the fight or

Writing Assignment: Social Phobia Social phobia‚ also known as social anxiety disorder‚ is a psychiatric disorder characterized by anxiety about being in public or social gatherings. People with social phobia have an intense fear of being judged by others and of doing something that will humiliate or embarrass them. They become extremely self conscious and anxious during everyday social situations‚ which makes it difficult to make and maintain healthy relationships. Although this disorder sounds

Components that are involved in physical sensation come from both the central nervous system and the peripheral nervous system. To begin with‚ the somatic nervous system‚ which is part of the peripheral nervous system‚ is made up of nerve fibers that detect and carry information
