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

of its functions are regulated by the autonomic nervous system‚ or involuntary‚ meaning that we do not consciously have to contemplate digestion for digestion to occur. With this being stated‚ it would make sense that almost the entire gastrointestinal tract is made up of smooth muscle. Smooth muscle is very distinctive from the other types of muscle in the body due to the fact that it is not controlled consciously‚ but unconsciously regulated by the autonomic nervous system through the release of

There are two different types of cloning. One of the types is artificial embryo twinning it is the low-tech way to clone different animals. The other type is somatic cell nuclear transfer‚ this method produces the same result‚ but in a different way. somatic cell nuclear transfer is performed in this way: Researchers get a somatic

The autonomic nervous system (ANS) consists of three main anatomical divisions: sympathetic‚ parasympathetic and enteric nervous systems. The sympathetic (SNS) and parasympathetic (PNS) systems provide a link between the central nervous system and peripheral organs. The sympathetic nervous system originates in the spinal cord. Specifically‚ the cell bodies of the first neuron (the preganglionic neuron) are located in the thoracic and lumbar spinal cord. Axons from these neurons project to a

and no new biological material or animals are crated. However‚ in 1997 an experiment was conducted and the result was the cloning of a sheep named Dolly. This process was different as it used a new technique of cloning known as somatic cell nuclear transfer. When the somatic cell nuclear transfer technique was first conducted the result was an animal that was a genetic twin‚ delayed in time however‚ of a sheep. This technique can also be used in the production of an embryo in which cells known as embryonic

Presentation Questions Ecstasy 1. Explain how the brain normally regulates serotonin. How does ecstasy act in the brain‚ & what neurotransmitters does it affect? - Normally‚ the brain regulates serotonin (5-HT) by taking up the release in neighboring neurons. - With ecstasy‚ the neuron is still supplied with 5-HT directly. However‚ ecstasy MIMICS 5-HT by blocking the reuptake of serotonin‚ [causing the release of high levels of 5-HT into the synapse]‚ which induces euphoria & the
