Unit 1- Principles of Anatomy and Physiology Functions of the skeletal system There are five main functions of the skeletal system. To protect‚ to support‚ movement‚ cell production and storage. The skeletal system protects delicate and important organs from harm. An example of this is the ribcage. This protects your heart and lungs from anything that tries to harm it. Another example is the brain. The brain is protected by the skull. The skeletal system also provides support for the body as it

Society expects the criminal justice system to provide justice for everyone by protecting the innocent‚ to punish and convict the guilty‚ and to rehabilitate them in an attempt to stop them reoffending. It is supposed to give fair justice for everyone‚ regardless of gender‚ but much is written that suggests that the criminal justice system is gender-biased. Gender bias was not formed by the justice system‚ but it does reflect

upwind generators. This entire assembly rotates when wind blows past the blades‚ hence the name “rotor.” In many small wind turbines the rotor is coupled to a shaft which is coupled to an alternator‚ a device that produces AC electricity. Fig 3.12 Anatomy of a Wind Generator Electricity is produced by alternators which consist of two main parts: a stationary winding‚ known as the stator; and rotating magnets‚ known as the rotor. Metal magnets are preferred to electromagnets in

When an environment changes‚ an organization must be able to gather‚ process‚ and disseminate information very quickly. Decision making is decentralized. 7) Discuss task specialization. Task specialization is the process of dividing the work into smaller tasks with high levels of task specialization suggesting that each person perform a very narrow range of activities while a low specialization task employees

Chapter 16 Notes The heart lies in the mediastinum and is surrounded by a doubled layered membrane called the pericardium. The outer most layer of the pericardium is called the fibrous pericardium‚ which anchors the heart to surrounding structures. The inner layer is called the serous pericardium and is composed of two layers. The outer portion is called the parietal pericardium‚ the inner portion is called the visceral pericardium (epicardium). Epicardium- outer most layer of the heart wall

HUMAN ANATOMY AND PHYSIOLOGY AN INTRODUCTION TO RESPIRATION In this essay we will consider a few major aspects of respiration. We shall first consider the interesting history of the study of respiration before moving on to our modern understanding of respiration. We will look at the structure and function of the respiratory system including the upper and lower respiratory tracts with a note on the control system. Secondly we will consider the physiology of respiration. Thirdly we will discuss some

tendency for recurring seizures. There are different types of epilepsy and seizures. Epilepsy drugs are prescribed to control seizures‚ and rarely surgery is necessary if medications are ineffective. Epilepsy is a disorder of the brain’s electrical system. Abnormal electrical impulses cause brief changes in movement‚ behavior‚ sensation‚ or awareness. There are around 180‚000 new cases of epilepsy each year. About 30% occur in children. Children and elderly adults are the ones most often affected
