Chapter 9 & 10 Short Answer and Critical Thinking CHAPTER 9 Short answer 15. Name and describe the four functional abilities of muscle that are the basis for muscle response. Contractibility- is the ability to shorten forcibly when adequately stimulated. This ability sets muscle apart from other tissue types. Extensibility- is the ability to extend or stretch. Muscle cells shorten when contracting‚ but they can stretch even beyond their resting length‚ when relaxed. Elasticity-

Aircraft structures Abstract: The aircraft structure is an important part where the structure of an aircraft depends on the optimum requirement of the customer and the environments in which it will be going to fly for the major time. It has to go several checks at regular interval of flying hours under proper inspection. This paper contains the basic information regarding the components of an aircraft and the basic concept of its design. The main criteria of design and its philosophy is the

Some of the symptoms include pain‚ fatigue‚ dyspnea and anorexia. Firstly‚ fatigue‚ also known as asthenia‚ is one of the most common symptoms among patients under palliative care. It affects up to 80% of patients in palliative care. (Ferrell‚ B.R.‚ et al 2015). Fatigue can be defined as weakness‚ tiredness and the lack of energy (Radbruch et al.‚ 2008). If the patient is experiencing fatigue‚ they may not have the energy and ability to perform simple tasks such

Truck drivers and operators spend a significant proportion sitting for extend periods of time and increasing demand for comfort. There are a variety of reasons for ergonomics to improve driving comfort conditions in vehicles.

overlap with each other and result in a stronger muscle contraction than a stand-alone twitch • tetanus - if stimuli continue to be applied frequently to a muscle over a prolonged period of time‚ the muscle force will eventually reach a plateau • fatigue - a decline in a muscle’s ability to maintain a constant force of contraction after prolonged‚ repetitive stimulation. • isometric contraction - When a muscle attempts to move a load that is greater than the force generated by the muscle • isotonic

Introduction On April 28‚ 1988‚ Aloha Airlines flight 243 underwent an explosive decompression in its passenger cabin at feet 24‚000. Although the aircraft underwent extensive structural damage‚ it was able to land safely. Investigations identified metal fatigue in the skin panel fuselage as proximate cause of accident due to poor maintenance. Nevertheless‚ the accident analysis revealed a more complex chain of causes‚ including aging of aircraft structure‚ structural design‚ maintenance methodology and safety

One of my favorite articles of clothing is Military fatigue/camouflage‚ commonly known as BDU’s; I’ve been a fan of this gear since my early teenage years. In the early 90’s Fatigues was a growing trend worn by urban kids and hip hoppers which then lured me from its rugged and militant flair‚ I immediately adopted the fashion.
