Cardiac muscle, like skeletal muscle, is a striated muscle and much of the mechanism of contraction is similar between the two muscle types. The electrophysiology of the two muscles differs: First ,the cardiac action potential is not initiated by neural activity. Instead, specialized cardiac muscle tissue in the heart itself initiates the action potential, which then spreads directly from muscle cell to muscle cell. Neural influences have only a modulatory effect on the heart rate. Second, th...

Abstract The functional anatomy of the respiratory system and mechanism of respiration. The respiratory system consists of nostrils, nasopharynx, larynx, trachea, bronchi, bronchioles, alveoli duct and alveoli. The structures included from nostrils to terminal bronchioles will have 16 divisions, while the remaining structures show 7 divisions, giving a total of 23 divisions for the respiratory tract. The divisions are formed by the repeated branching of each segment of the tract. Structures l...
Introduction The branch of pharmacology that relates drug concentration to biologic effect is known as pharmacodynamics. Major goals of this area of study are determining the proper dose to administer to elicit the desired effect while avoiding toxicity. Although pharmacokinetics can be used to determine dosing requirements necessary to maintain a particular drug concentration, it is the relationship between drug concentration and effect that ultimately decides appropriate dosing. The ul...
Ten Tree diseases affecting forest tree species A) Common name: Root rot disease Botanical name: Cochliobolus sativus. Literature review: Root rot disease is a disease that attacks the roots of trees growing in wet or damp soil. Prolonged exposure to excess water causes waterlogging, which interferes with aeration of the roots, leading to low oxygenation and decay. Causative Agent: Phytophthora spp. Particularly species P.cinnamomi. Others include Pythium, Rhizoctonia and Fusarium..... B) C...
