Without a healthy body, we can do nothing. Good health enables you to enjoy your life. How can we keep healthy? For me, there are three main ways to keep healthy. First, it is necessary to keep a balanced diet, which is the basis of good health. It is better for us to have enough fruit and vegetables every day. Secondly, it is important to take regular exercises, such as swimming, jogging doing yoga and so on. Last but not least, it is essential to keep in a good mood. Relaxation and entertainment are ways to renew our spirits and release our stress. When we make healthy habits a part of our everyday life, we are bound to keep healthy. 學(xué)習(xí)記錄卡 3 ( 第 25 頁 ) （ Units13~18） 學(xué) 習(xí) 過 程 1. A√B√C√ 2. A√B√C√ 3. A√B√C√ 4.

My webbased courses include English, Chinese, Computer, Math, Politics and so on. I like English best. We can join online discussion forums, but it39。s very difficult for me to understand what the speakers say. Every day we plete our home work on the puter and send our homework to the tutor. He or she will solve the difficulties and puzzles in tutorial. I love my TV University life which make my life colorful and meaningful. 14 請(qǐng)您刪除一下內(nèi)容， O(∩ _∩ )O 謝謝?。?！ 2021 年中央電大期末復(fù)習(xí)考試小抄大全，電大期末考試必備小抄，電大考試必過小抄Acetylcholine is a neurotransmitter released from nerve endings (terminals) in both the peripheral and the central nervous systems. It is synthesized within the nerve terminal from choline, taken up from the tissue fluid into the nerve ending by a specialized transport mechanism. The enzyme necessary for this synthesis is formed in the nerve cell body and passes down the axon to its end, carried in the axoplasmic flow, the slow movement of intracellular substance (cytoplasm). Acetylcholine is stored in the nerve terminal, sequestered in small vesicles awaiting release. When a nerve action potential reaches and invades the nerve terminal, a shower of acetylcholine vesicles is released into the junction (synapse) between the nerve terminal and the ‘effector’ cell which the nerve activates. This may be another nerve cell or a muscle or gland cell. Thus electrical signals are converted to chemical signals, allowing messages to be passed between nerve cells or between nerve cells and nonnerve cells. This process is termed ‘chemical neurotransmission’ and was first demonstrated, for nerves to the heart, by the German pharmacologist Loewi in 1921. Chemical transmission involving acetylcholine is known as ‘cholinergic’. Acetylcholine acts as a transmitter between motor nerves and the fibres of skeletal muscle at all neuromuscular junctions. At this type of synapse, the nerve terminal is closely apposed to the cell membrane of a muscle fibre at the socalled motor end plate. On release, acetylcholine acts almost instantly, to cause a sequence of chemical and physical events (starting with depolarization of the motor endplate) which cause contraction of the muscle fibre. This is exactly what is required for voluntary muscles in which a rapid response to a mand is required. The action of acetylcholine is terminated rapidly, in around 10 milliseconds。 an enzyme (cholinesterase) breaks the transmitter down into choline and an acetate ion. The choline is then available for reuptake into the nerve terminal. These same principles apply to cholinergic transmission at sites other than neuromuscular junctions, although the structure of the synapses differs. In the autonomic nervous system these include nervetonerve synapses at the relay stations (ganglia) in both the sympathetic and the parasympathetic divisions, and the endings of parasympathetic nerve fibres on nonvoluntary (smooth) muscle, the heart, and glandular cells。 in response to activation of this nerve supply, smooth muscle contracts (notably in the gut), the frequency of heart beat is slowed, and glands secrete. Acetylcholine is also an important transmitter at
