  • Sternoclavicular Sprain Case Study

    701 Words  | 3 Pages

    1. What is the mechanism of injury for a sternoclavicular sprain? In the majority of sternoclavicular sprains, what is the direction of clavicle displacement? The majority of injuries result from compression related to a direct blow, as when a supine individual is landed on by another participant, or more commonly, by indirect forces transmitted from a blow to the shoulder or a fall on an outstretched arm. The disruption typically drives the proximal clavicle superior, medial, and anterior.

    Aberrant right subclavian artery (ARSA) is the most common aortic arch anomaly. The estimated incidence is 0.5-2%. They are often asymptomatic, but approximately 10% of people may complain of dysphagia lusoria4 or other compressive symptoms. In ARSA of the Innominate artery, the right subclavian artery arises as its own branch from the aortic arch distal to the origin of the left subclavian artery.

    allow for a litter of 8 to 10 pigs. In fetal pigs, “the brachiocephalic artery splits into the right subclavian artery and the bicarotid trunk which then splits into the right and left common carotid arteries” (“Human/ Pig Comparisons”). Nonetheless, humans do not have a “bicarotid trunk and instead the left common carotid artery branches directly from the aorta” (“Human/ Pig Comparisons”). Fetal pigs also do not have iliac arteries that humans have. Additionally, because of the fact that pigs are quadrupedal

  • Aortic Arches In Vertebrate Analysis

    841 Words  | 4 Pages

    Aortic arches are also called as pharyngeal arteries. They are vascular structures that emerge from the ventricle of the heart. There are 6 pairs of these arches in embryonic stages which give rise to several major arteries later. They arise from the aortic sac and are present on the ventral and dorsal aorta. As discussed earlier that there are 6 pairs of aortic arches present in embryonic stages giving rise to several arteries are as follows: Arch 1st and 2nd: The first and second arches

    the heart is artery; vein is towards the heart). If they connect arteries and veins then they are called capillaries and if an organ is receiving or returning the blood then the organ’s name is a part of the blood vessel’s name. Circle of Willis is a looped network (anastomosis) of arteries at the base of the brain. Branches of the internal carotid arteries form the front of the circle and branches of the posterior cerebral arteries form the back of the circle, with smaller arteries, collectively

  • The Effects Of Temperature On Heart Rate And Strength Of Contraction

    2152 Words  | 9 Pages

    Question: What are the effects of temperature on heart rate and strength of contraction? The effects of temperature can either increase the heart rate or decrease the heart rate. The temperature can also effect the strength of contraction either by making the contraction stronger or weaker. Background: Explain on the cellular level how dropping warm Ringers solution on the frog’s heart would affect the cells of the SA node. Dropping warm Ringers solution on the frog’s heart would increase the heart

  • The Importance Of Blood Pressure

    1677 Words  | 7 Pages

    Introduction: BLOOD PRESSURE (BP) is defined as the "pushing force exerted by the blood against the vessel walls". This pressure is highest in the arteries and lowest in the veins. As a result, the blood moves from the arteries through the organs into the veins and back into the heart to begin the cycle over again. The heart acts as a pump to create the high arterial pressures that keep the blood flowing. Because it is the "driving pressure" that pushes the blood through the organs, the ARTERIAL

(Herbert, 2014) Atherosclerosis is the buildup of a waxy plaque on the inside of artery, the arteries are blood vessels that carry blood from the heart through the body, and they are lined by a thin layer of cells called the endothelium. The endothelium works to keep the inside of arteries toned and smooth, which blood keeps flowing. (Zarbock, et al, 2008) There are two major types

  • Beta Blocker Research Paper

    1115 Words  | 5 Pages

    Beta Blockers That are Used in Managing Heart Failure Heart failure occurs when the heart is not able to pump or fill with blood to reach the body needs, leading to decrease in pumping action and cardiac output. The body will sense the hypo-perfusion of vital organs then activate the compensatory mechanisms. First compensatory mechanism is cardiac compensation by increasing the heart rate, contractility, or myocardial hypertrophy and remodeling. Additionally, systemic compensation by increasing

  • Gout Case Study

    868 Words  | 4 Pages

    Gout is the most common inflammatory type of arthritis affecting adults. The clinical syndrome of gout arises from deposition of urate crystals in joints,where they cause an inflammatory response, and in soft tissues where they do not. Crystal deposition occurs when serum becomes saturated with urate,the final breakdown product of purine metabolism.It is characterized by chronic hyperuricemia which is defined as serum urate levels above 6.8mg/dl,the level above which the physiological saturation
