Lesson aims Review lecture 1 Review lecture 1 · (part 1) (part 1) Henry's Law · Respiratory responses & adaptations · Move onto the cardiovascular system · Lecture 1 recall task 1) Identify the route that air takes from the atmosphere to the blood (e.g., air enters through the mouth and then...). 2) Explain the mechanism of how air is drawn into the body with reference to Boyle's law and diffusion. 3) With reference to Dalton's law explain why training at altitude can be problematic for athletes. Henry's Law · When a mixture of gases is in contact with a liquid, each gas will dissolve in the liquid in proportion to its partial pressure. · Greater concentration of gas, the more and

above. As a soccer coach, you often tread a thin line between what has been proven scientifically and what is considered “best practice.” Unfortunately, science in soc- cer is still in its infancy, and there are still many question marks in this regard. Soccer is a very complex sport in which different physical abilities are used in tan- dem, often competing for adaptation. Because not everything in the field of soccer science has been “mapped out” yet, we often have to rely on our experience and intuition. I hope this book can help in some small way to make you a better “reasonable
AMYGDALA – A structure in the forebrain which is a component of the limbic* system. It is implicated in control of emotions. ANTAGONIST – A chemical which blocks receptors* and stops (inhibits) the effects of agonists*. ANTERIOR – Towards the front, e.g. anterior cingulate cortex – frontal part of the cingulate cortex (part of the brain). ANTEROGRADE AMNESIA – Inability to remember new information since the moment, which triggered amnesia (e.g. stroke, head trauma). ANTEROGRADE TRANSPORT – Transport of materials, e.g. neurotransmitter molecules, along the axon, away from the neurone body to axon terminals* where the material is needed. It uses neuronal cystoskeleton, i.e. the system of neurotubules and neurofilaments which make a kind of scaffolding inside a neurone. APHASIA – Absence of speech. ASSOCIATION CORTEX – Areas of the cerebral cortex which are involved in higher processing of sensory information. They integrate new information with that stored in the memory.

Diffundeeruvad keemilised signaalid kasutatakse: Parakriinne signalisatsioon – some are local mediators that act on neighboring cells, reaching their targets by diffusion over relatively short distances 3 Autokriinne signalisatsioon – secreted chemical also acts on the cells that secreted it Endokriinnääre – hormones are secreted into the blood by specialized glands – to act on various tissues around the body Sünaptiline signaliseerimine – nerve cells release chemicals at their endings to affect the cells they contact Autokriinne, parakriinne ja endokriinne regulatsioon.

hazards that can come with having an office job. It doesn't have to be that way. Human bodies are made to move. It is recommended that a person break for 5-10 minutes for every hour spent at a workstation. Working "mini" activity breaks into your day can really make a difference in how you feel and even how well you perform your job. Even the busiest person can do it. Just five minutes of movement every hour or two can boost energy and improve your attitude. You'll find that getting your blood pumping and oxygen circulating will help you concentrate better and be more productive, calm, and efficient. Breaks can minimize strain, but they can not relieve stress or improve flexibility, for example. Most people should stretch prior to any strenuous activity. Routine activities like typing or using the phone can lead to injury over a period of time. So, stretching can: - increase your flexibility. Flexible muscles can improve your daily performance. Tasks
These results indicate that HER is related to a lower cortisol response to psychosocial stress. In conclusion these results suggest that HER and DAR have an impact on the cortisol response.
