Dopamine receptor

The patient (pt) in room 584 is an 84-year-old Caucasian woman who was transferred to Lynchburg General hospital on December 12, 2016 from Stonewall hospital in Lexington in order to receive pulmonary care. Though she was admitted for unspecified dementia without behavioral disturbances, she was originally hospitalized at Stonewall since September 21, 2016 for atrial fibrillation with a low ventricular response rate, and dyspnea. She has co-morbidities of Parkinson’s disease and Lewy body…

disease of the nervous system affecting movement. Dopamine is a neurotransmitter concentrated in the substania nigra, part of the basal ganglia, and is important in controlling smooth, coordinated movement. When dopamine-producing cells die or fail to produce enough dopamine neurodegeneration occurs and Parkinson’s symptoms begin to appear. When the brain loses dopamine cells, dopamine and acetylcholine are put out of balance and cholinergic receptors become excited; this produces tremors and…

Dopamine is a chemical sent as a neurotransmitter. Dopamine is a chemical reaction that's going on in your brain, that stimulates on how you feel. Dopamine is also linked with the reward center of your brain, Dopamine sends a message to the reward center that can bring pleasure and motivation. It's basically what most of your confidence and joy is built up of, And key force of most of our actions. But on the down side low dopamine levels can lead to serious problems. That's why it is important…

Administration (FDA) in 1967. (David A. Williams ) Haldol is original brand name of haloperidol, which now produced under multiple trade names as patent protection has expired. Haloperidol is a derivative of butyrophenone and acts by blocking the effects of dopamine, a chemical in the brain that affects…

interaction between negative and positive reinforcement throughout stages of addiction. These opponent processes start at the initial drug intake and, in the long run, results in the hypofunctioning of dopaminergic neurotransmitters, such as D2 and dopamine, but increase in stress chemicals including corticotropin releasing factor (CRF)(Johnson et al, 2016). These changes were said to be the effort of the brain to counteract the hedonic effect of drug use (Solomon and Corbit, 1974) and…

ear, the incus and stapes. As the stapes moves, it pushes a structure called the oval window in and out. This is passed onto the cochlea, which is a fluid-filled snail-like structure that contains the receptor organ for hearing. The cochlea contains the spiral organ of Corti, which is the receptor organ for hearing. It consists of tiny hair cells that translate the fluid vibration of sounds from its surrounding ducts into electrical impulses that are carried to the brain by sensory nerves. As…

it matters: Dopamine is important to because dopamine is the neurochemical of love, addiction, reward, motivation, learning, sleep, memory, movement, and many other things necessary to the proper function of the human body. Extreme and abnormal levels of this neurochemical can lead to certain serious diseases, both mental and physical. Low levels of dopamine can cause Parkinson's disease, addiction, ADHD, autism, bipolar disorder, schizophrenia and other things. High levels of dopamine can have…

as schizophrenia, and other psychiatric illnesses in adults and children, including pervasive developmental disorders (PDD), autism, and attention-deficit disorder (ADD) [1–3]. It acts primarily by selective antagonism of dopamine Type 2 (D2) and serotonin Type 2 (5HT2) receptors in the brain [4–6]. Apart from minor N-dealkylation, the major pathway of biotransformation of RIS is hydroxylation at the 9_ position on the pyrido-pyrimidone ring to 9-hyroxyrisperidone (9-OH-RIS), mediated by the…

neocortex houses the motor cortex and thus is responsible for motor control, which is the primary impairment in Parkinson’s Disease (Kaas & Stepniewska, 2016 SD). Onset typically follows a significant drop in the presence of the neurotransmitter dopamine, which in this case is generated from a part of the brain called the substantia nigra. The substantia nigra supplies neurotransmitter to the striatum, a region which receives input from the neocortex and contains the neurons, or nerve cells…

With each drag and puff of smoke its cold steely hands grips the willing victim who will find it difficult to escape addiction’s powerful grasp. Of particular interest for the respiratory therapist is the addiction to nicotine. It is important for the healthcare worker to know how this addiction can occur, because tobacco use is associated with a variety of pulmonary diseases. One such disease is chronic obstructive pulmonary disease, or COPD. The prevalence of addiction to drugs, such as…
