INTRODUCTION Give a brief description in your own words of the objectives and aims of this practical. The aim of this practical is to investigate how the autonomic nervous system (ANS) affects the motility in the gastrointestinal tract‚ by experimenting with the release of neurotransmitters. A. RESPONSES TO NERVE STIMULATION Attach a copy of your experimental recordings showing a period of spontaneous contractions and the response to stimulating the nerves

Activity 1 – The Muscle Twitch and Latent 1) Define the terms skeletal muscle fiber‚ motor unit‚ skeletal muscle twitch‚ electrical stimulus‚ and latent period. Skeletal Muscle Fiber: Skeletal muscle cells that are composed of hundreds to thousands of individual cells that produce muscle tension. These fibers are what move our bodies and generate muscle tension/force that enables us to have manual dexterity. Motor unit: consists of one motor neuron and all of the skeletal muscle fibers that

Apparent Weight: Person on Scale in Elevator A person with mass‚ m‚ who is located at or near the surface of the Earth will always have some weight W=mg. When a person stands on a scale‚ the reading (the number of pounds or newtons) on the scale is actually the Normal Force that the scale exerts back towards the person to support the person’s weight. (Note that the person and the scale are stationary relative to each other‚ in other words they are always in contact with each other‚ so they always

Physical fitness is important in everyday life‚ but being physically fit during pregnancy is important as well. Pregnant women fall into a group specified as a special population. Questions continually arise about safety‚ training recommendations‚ and limitations while pregnant. Physical fitness helps a woman with the physical demands that pregnancy imposes on her body‚ as well as providing everyday health benefits. Exercise can be helpful with common pregnancy issues and make childbirth easier

The nervous system is always in control of all activities during movement. When a neurotransmitter or message is sent for movement to occur‚ your body releases energy‚ in the form of adenosine triphosphate (A.T.P.). A.T.P causes the contraction or shortening of skeletal muscle. Muscles contract and shorten and as a result of this they are responsible for the movement of the body. In order to have movement the body needs ligaments‚ tendons muscles‚ joints‚ bones and the neurotransmitter or message

Another issue that emerged during the industrial Revolution was the high levels of child labour. Children as young as 5 years of age worked in the factories and mines of the times (Oxford University. 2013. 66(2)). Workdays of 13 to 14 hours where common in children ages 7 and up (Hutchins‚ Hariison‚ 1911:25). These long hours were accompanied by poor working and living conditions. Up to 80 children stayed in one room and this lead to health problems as it made it possible for ilnesses and fevers

There was a lack of hygiene during the industrial revolution. There was no knowledge of sanitary care‚ so disease spread very fast. Soon air‚ water‚ and other necessities became unsafe to consume because of all the pollution caused by the factories. People would live in overcrowded cities in damp and dirty homes‚ which would cause them to get sick. In most cities there were no washing facilities and pigs were let to get rid of the waste on the streets‚ so living in a city during this time would be
