The functions are contraction of uterine smooth muscle during labor. Contraction of myoepithelial cells around breast ducts and alveoli to stimulate milk flow and it is queried as to whether oxytocin release actually causes the onset of labor. Oxytocin primarily affects uterine smooth muscle - increasing both the frequency and duration of action potentials during uterine contractions. Oestrogen enhances the effects of oxytocin by lowering the membrane potential of smooth muscle cells. As the fetus

the disease until 1939‚ when New York Yankees first basemen Lou Gehrig retired because of his diagnosis (4). Specifically referred to as a "neurodegenerative disease"‚ ALS is the lack of nourishment to muscles (5). If you break "Amyotrophic" down into its latin meanings "A" means no‚ "Myo" is muscle‚ and "Trophic" means nourishment (6). It slowly eats way at the ability to eat‚ speak‚ walk‚ and breath‚ and will eventually lead to the victims death. ALS is the most common of five motor neuron diseases:

115 mmHg at rest to 150 mmHg during severe exercise. When thr degree of exercise increases‚ the skeleton muscle needs more energy(ATP) for rapid contraction by carrying out aerobic respiration. The skeleton muscle required faster uptake of oxygen and removal of carbon dioxide. At the same time‚ skeleton muscle carries our anaerobic respiration to provide addition amount of ATP for rapid contraction. Partially oxidized lactic acid is produced during anaerobic respiration which lowers the blood pH. When

Pectoralis minor’s origin is ribs 3-5 and insertion at coracoid process of scapula‚ it depresses scapula and elevates ribs. Rhomboids Major and Rhomboids Minor’s origin at spinous processes T1-T4‚ insertion at medial border of scapula‚ they move scapula. Serratus anterior’s origin is at ribs 1-9‚ insertion is at medial border of scapula

Hutchins 10/27/15 Vitamin D Deficiency Regarding Muscles Vitamin D deficiency has been tied to mainly bone pathologies. Recent research shows that the effects of Vitamin D span further than just affecting bones and particularly cause muscle weakness. Vitamin D is responsible for aiding in the absorption of other minerals‚ such as calcium. Calcium is a key ligand in muscle contractions‚ thus‚ Vitamin D indirectly can effect muscle contractions. An article published in Nutrition Reviews‚ Vitamin

• Cardiac hypertrophy- This is when the heart increases in size and volume‚ the wall of the left ventricle will get thicker with the help of constant exercise‚ this leads to an increased force of contraction. This will allow the heart to pump out a larger amount of blood with each pump‚ therefore a more efficient heart as it will not have to beat as many times as an untrained heart. • Increase in stroke volume and cardiac output- Stroke volume is defined as the amount of blood the heart is able to
