Agonist

create flexion of the hip the hip flexor (agonist) contracts concentrically (isotonic) and at the same time the hamstring (agonist) also contracts concentrically (isotonic) to create flexion of the knee. When you adopt this position you also must lean slightly forward to maintain balance, this is achieved by dorsiflexion of the ankle which is caused by the tibialis anterior (agonest) contracting concentrically (isotonic). Simultaneous to their respective agonist muscles the antagonist muscles of the

practically 2:1 (Carson, 2012). The most common treatment for ADHD is methlyphenidate, or Ritalin, a dopamine agonist/ norepinephrine agonist that inhibits reuptake of the neurotransmitter dopamine and norpinephrine. Methlyphenidate increases dopamine in the dorsal striatum, and both dopamine and norepinephrine in the prefrontal cortex. Notwithstanding, the fact that MPH is a dopamine agonist suggest that this disorder may be

positioned on her hands and knees. She raises her left arm while simultaneously extending her right hip and knee. The muscle fibers of her anterior deltoid engage and act as the agonist for shoulder flexion while the gluteus maximus engages as the agonist for hip extension. The quadriceps femoris group act as the agonist for knee extension. The antagonists for shoulder flexion are the posterior deltoid, latissimus dorsi, teres major, pectoralis major, and the triceps brachii. The antagonist for her

motor unit to control a biological joint is an agonist-antagonist muscle-tendon pair. Such a muscle-tendon relationship allows for simultaneous control of joint state (position and speed) and impedance (stiffness and damping) for upper and lower extremity motor tasks. At least one pair of antagonistic muscles is needed for each degree of freedom of a limb in order to control joint state, torque, and impedance [12]. Proprioceptive feedback from this agonist-antagonist architecture is crucial to reliable

Synaptic activity is vital for the passage of information throughout the nervous system, as it allows for electrical impulses to be passed from one neuron to another. Electrical impulses in the form of action potentials are passed through the axon of a neuron towards the axon terminal. This information is then passed across the synaptic cleft to receptors present on the postsynaptic membrane via the process of neurotransmission. Drugs can interrupt this specific process in a variety of ways such

Salbutamol (also known as albuterol in USA) is one of the most famous short-acting β2 agonists. It has become first line treatment for asthma due to its effectiveness. I met this drug in a dispensing session in the first term and I think is a good example of what we have learnt so far. In this essay I will tell you what I know about this drug. Salbutamol is sold in its sulphate form and is marketed as a racemic product. According pharmaceutical chemistry this means that in it, it has 50% of the

This MOT will focus on initiation of pharmacological management of depression in PD patients without dementia. Brown R.G. et al. concluded that depression in PD can present as either “anxious-depressed” or “depressed” (Brown R.G., et al. 2011). There has been no clear guideline for management of depression in PD. There have not been many large, reliable trials that investigate anti-depressant properties of current PD medications. Currently, dopaminergic drug especially ropinirole has been shown to

names: Ventolin, Respigen, Salamol, Asthalin, Salapin and Broncolin. Drug Class: Therapeutic class: bronchodilator. Pharmacologic class: sympathomimetic (stimulates the sympathetic nervous system). It is also classified as a SABA (short acting β2-agonist). Formulations: The most common administration is by inhalation of a pressurised metered dose aerosol. Inhalation of Salbutamol directly reaches the lungs and acts rapidly with fewer side effects, but only 10-25% is actively absorbed as the remainder

“Bronchitis” is an inflammation that affects the lungs, “broncho” meaning lungs, “itis” meaning inflammation of an organ. Bronchitis comes in two types, Acute and Chronic bronchitis. Acute Bronchitis is an infection that also occurs to the bronchial tubes, which gets swollen. It is usually caused by a virus however, lasts for about 2 to 3 weeks. This commonly happens after someone had a cold or flu. It only happens for a short period of time. Chronic bronchitis is the inflammation of the lungs that
