and lungs operating while the muscles shut down. Patients with little dopamine-producing neurons in the brain often fail to get their muscles shut down and may experience violent hitting and shouting while they sleep. Those with low levels of acetylcholine-producing neurons in the brainstem are more likely to have sleep apnea ("Sleep Disorders Linked To Faulty Brain Chemistry, Study Finds”). Sleep disorders are becoming more common in today’s society. Work, school, and other demanding tasks are…

It’s interesting to see the progression of weapons from the early beginnings to now. Most people believe that chemical warfare agents were first introduced during the World Wars. Interestingly enough, the concepts of these agents were developed as early as 600 B.C. They weren’t known as chemical warfare agents however; the techniques that were used mimic the action of these agents that are being used today. During the Peloponnesian War between Sparta and Athens, the Spartan army used a mixture…

I need my brain to know when to move. When playing volleyball, I need to be able to move around in order to get to where the ball had been hit. In order to do this my brain uses neurons to transmit signals to my body that allows me to make quick motions. Sensory neurons send messages from my muscles and sensory organs, like my eyes and ears, to my brain and spinal cord. My brain then processes that message and sends a response back to my muscles via motor neurons. If, for instance, one of my…

together in the complex process of the digestion process (Huether & McCance, 2012). There are three phases of gastric secretion, first being the cephalic phase, which is stimulated by the thoughts , smells and taste of food. Stimulation releases acetylcholine and the release of gastrin-releasing peptide, thus indirectly stimulates hydrogen ions. The second phase is the gastric phase, which is stimulated by the expansion of the stomach. Partially digested proteins and amino acids activate…

postpartum depression is mainly chemical imbalances. The chemicals imbalance involved are “abnormalities in the delivery of certain key neurotransmitters.” These neurotransmitters include serotonin, the chemical involved in the feeling of well-being, acetylcholine and catecholamines, a group of neurotransmitters that are comprised of dopamine, norepinephrine, and adrenaline. With the balances of all these happiness-inducing neurotransmitters skewed significantly because of the birth of her…

Halle Pietro 11/11/16 Memory Essay Psy101-092WB The mind is a very mysterious process that researchers and doctors still do not completely understand. It is a giant complex command center that is capable of knowing everything because of all that it is exposed to. In memory video 1, they discuss “The Mind Hidden and Divided”. The video is an overview of Sigmund Freud’s research and how certain events and experiences originating in the subconscious understanding of our conscious lives. The topics…

Prelude Maintenance of robust wildlife communities is valued by many Americans as a central aspect of national pride and cultural heritage. What is less recognized is the role healthy ecosystems play in the health and sustenance of human populations. When wildlife or a piece of a wildlife system directly benefits human well-being it is referred to as an ecosystem service. Decline in bee populations worldwide is putting humankind at risk of damaging it’s most imperative ecosystem service: animal…

frontal lobes, but the atrophy occurs in all areas of the cortex. The cause of Alzheimer’s is still unknown, but there is factor’s that contribute to this disease, such as neurochemical factors, which include deficiencies in the neurotransmitters, acetylcholine, somatostatin, substance p and norepinephrine (“Pathophysiology made incredibly visual!” p. 76). As well as a viral factor, which are a slow, growing central nervous system viruses, trauma, and genetic factors. There are three types of…

Neuropsychologists used a functional magnetic resonance imaging (fMRI) on depressed patients to see how differences in the brain activity when compared to normal people and the result showed that depressed patients have a decreased activity in dorso lateral pre-frontal cortex (DLPFC) but the activity of the amygdala, where is responsible to our emotional reactions such as sadness and happiness, was relatively increased (2007). It would then explain why patients who suffered from depression tend…

Spiriva HandiHaler There are many types of inhalation equipment and devices on the market. I decided to research and compare the Spiriva Handihaler with the other bronchodilators. To find out why it was chosen for a resident where I work, who has C.O.P.D. I want to develop a broader understanding of the medication. It is important to be aware of the benefits or disadvantages of the medications that I dispense, in order for me to be thorough, and efficient in my job duties. Spiriva…
