APSS5802 Assignment 1 Conduction Aphasia Yeung Wai 16030669G Introduction of conduction aphasia These days‚ aphasia has become an increasingly prevalent disorder not only seen in the older adults but also in the younger population (Engelter et al.‚ 2006). In the United States‚ there is approximately 80 thousand new cases of aphasia per year (National Stroke Association‚ 2008). Aphasia can be divided into various types‚ namely expressive aphasia‚ receptive aphasia‚ conduction aphasia‚ anomic aphasia

Tutorial 1 (Conduction and Convection) 1. Consider a composite structure shown on below. Conductivities of the layer are: k1 = k3 = 10 W/mK‚ k2 = 16 W/mK‚ and k4 = 46 W/mK. The convection coefficient on the right side of the composite is 30 W/m2K. Calculate the total resistance and the heat flow through the composite. (0.46‚ 173.9 W) 2. Consider a 1.2-m high and 2-m-wide glass window whose thickness is 6 mm and thermal

The cardiac electrical activity is produced and controlled by the Sinoatrial (SA) node in the right atrium and the Atrioventricular (AV) node in the interatrial septum. The electrical signals move through the cardiac conduction system fibres causing the atria and ventricles to contract and relax regularly between 60-100 bpm [1].when those electrical signals are interrupted as a result of a damage in the conduction system‚ the heart rate would become irregular or would either increase resulting in

The intrinsic Conduction System 1. List the elements of the intrinsic conduction system in order starting from the SA Node. SA node‚ AV Node‚ Av Bundle‚ left and right bundle branches‚ Purkinge fibers At what structure in the transmission sequence is the impulse delayed? Av Node Why? Allows completion of atrial contraction before initiation of ventricular systole. 2. Even though cardiac muscle has an inherent ability to beat. the nodal system plays a critical role in heart physiology. What

Cardiac Output most used tool to measure heart function The volume of blood ejected by the heart per minute. CO= Heart Rate x Stroke Volume EX: 70bt/min X 70ml/bt = 4900ml/min ~ 5L/min Regulation of Heart Beat HR is regulated through the balance of parasympathetic and sympathetic influence on the SA node. 1 action potential = 1 electrical impulse Parasympathetic: Slows HR Sympathetic: Speeds HR Parasympathetic Regulation of HR At rest‚ parasympathetic nerves will release Acetylcholine

called congestive heart failure. 2. What is third-degree heart block? What would the EKG tracing of someone with third-degree heart block look like? Third-degree block‚ also known as third-degree atrioventricular block is “a cardiac conduction system where there is no conduction through the atrioventricular node” (Budzikowski 2014). The patient will have severe bradycardia with independent atrial and ventricular rates. These patients may suffer from ventricular standstill‚ which

CARDIAC TUMORS INTRODUCTION Cardiac tumours occur quite rarely‚ with metastatic neoplasms three times more prevalent than primary tumours. A large variety of benign and malignant tumours of the heart have been described. These tumors are found mainly in the heart‚ but can occur in the pericardium or the great arteries. Secondary cardiac involvement from malignant tumors of adjacent organs (lung‚ thymus) or from kidney (Wilms tumor) or liver‚ or even remote organs‚ are also seen. ANATOMY AND PHYSIOLOGY
