1.) List and briefly explain the meaning of each of the following characteristics of muscle tissue; extensibility, elasticity, excitability, and contractility. Extensibility: The ability for muscle tissue to stretch. Elasticity: The ability of muscle to return to its normal resting size after being stretched. Excitability: The ability of muscle tissue to receive a stimulus from the nervous system.
• Be sure you know the root words and their meanings • Name and describe the three connective tissue layers found in a muscle: These layers allow parts to move on their own and also provide and area for blood vessels and nerves to move through. o Epimysium: The epimysium closely surrounds skeletal muscles. o Perimysium: This connective tissue divides muscle tissue into little segments. o Endomysium: This is a thin covering that houses bundles of muscle fibers called fascicles. • Define: antagonist, synergist, prime mover o Synergist: a muscle that assists the action of a prime mover o Antagonist: A muscle that act in opposition to a prime mover o Prime Mover: muscle primarily responsible for producing an action • List the various ways that muscles are named.

The function of these muscles is closely related to their structure and any differences in structure allow these two types of muscle to be identified. Cardiac and skeletal muscle is excitable tissue where stimulation of a single muscle fibre leads to excitation of a whole cell. They undergo contractions in response to an action potential, either resulting in pumping blood into pulmonary and systemic circulation or the movement of limbs. The contractile unit in both tissues is the same, the differences lie in the arrangement of these units and associate structures. The contractile unit consists of myofibrils which encompass repeating units of sarcomeres running end to end giving a striated appearance to the muscle.
Establishing and Maintaining good quality care relationships can be both rewarding and challenging for all involved. What are some of the difficulties that may face those providing and receiving care and how might these be overcome? In this assignment the key points that will be discussed are the difficulties that carers may tackle when providing care and the manner in which they may overcome them. The assignment will also examine the difficulties that the service user (person receiving care) may experience and how these may be overcome. Good quality care relationships are dependent on a number of factors that are changeable.
Concept of helping clients during the case management process The concept of helping clients during the case management process will reduce recidivism, enhance public safety, and promote success. The case management concept is complex because different components may happen at different times during the treatment process. Each individual is unique and different, so therefore, the treatment has to be different. Freeman (2001) stated, “The traditional case management plan calls for reduction of problematic symptoms by a certain percentage” (p. 77). Case managers are professionals who provide treatment and services to clients so they can live productive in society.
Introductory awareness of sensory loss | | Describe how a range of factors have a negative and positive impact on individuals with sensory lossSight LossHearing Loss | | Identify steps that can be taken to overcome factors that have a negative impact on individuals with sensory loss | | Explain how individuals with sensory loss can be disabled by attitudes and beliefsIndividuals with a sensory loss can be disabled by the attitude of not being capable and also not being able to manage by themselves. This message can come from society or from the person themselves. Many people live a full and satisfying life with a sensory loss, as long as they see it as a challenge, and take steps to rise to the everyday challenges presented.If they don’t overcome and identify these beliefs and attitudes It can knock their confidence and make them become isolated and lonely and therefore unable to achieve anything. | | Identify steps that could be taken to overcome disabling attitudes and beliefs. * Identify the attitudes and beliefs.
Kaitlin Caoili Mr. Boyd AP Lang 29 September 2014 The Triple Package In the article “What Drives Success” Amy Chua and Jed discuss three traits that lead to material success. These traits include: superiority complex, insecurity, and impulse control. Together, these qualities create the Triple Package. Some may argue that, alone, these traits could potentially be damaging and that these traits must be inherited. However, when properly used, the Triple Package leads to success and can be efficiently self-taught.
Despite the dismissal of physiognomy as pseudoscience (Alley, 1988; Cohen, 1973; Porter, 2003), a strong belief exists that the facial appearance does provide information about a person's personality, health, and future behavior (Hassin & Trope, 2000; Liggett, 1974). This phenomenon has also been termed as "kernel of truth hypothesis" (Berry & Finch Wero, 1993). Indeed, there is growing body of evidence that suggests that the facial appearance may provide some valid information regarding a person's personality and health. Since faces are processed largely holistically (Tanaka & Farah, 1993), modern research focuses particularly on whole face
The cerebellum receives information regarding the body's position in space to produce the coordinated movements necessary for performing exercises. The medulla oblongata helps regulate blood pressure and the heart beat while a person exercises. The cerebral cortex allows a person to consciously interpret the environment and remember the motor movements necessary to ride a bike, swim or participate in other activities. The primary motor cortex also communicates with other brain parts to coordinate and activate desired sequence of muscle movements. Lastly, the hypothalamus regulates changes inside the body during exercise.
