您現(xiàn)在的位置: > 大學(xué)英語(yǔ)六級(jí) > dendrites dendrites的音標(biāo)為[d?"nɑ?dri?ts] ,基本翻譯為“樹突”,速記技巧為:樹突(dendrite)——dend(樹)rite(詞綴,表示“傾向”)。
Dendrites這個(gè)詞源自希臘語(yǔ)詞根,意為“樹狀物”或“樹枝”。它的詞源可以追溯到古希臘語(yǔ)中的“δ?νδρον”(意為樹)和“πτερ?ν”(意為枝)。這個(gè)詞在英語(yǔ)中常用來(lái)指神經(jīng)元的樹突,這是神經(jīng)元接收信號(hào)的部分。
變化形式:詞形一般不變,但在一些情況下,如比較級(jí)和最高級(jí)中,可能會(huì)發(fā)生一些變化。
相關(guān)單詞:
1. axon(軸突):與樹突相對(duì),神經(jīng)元的軸突是神經(jīng)元發(fā)送信號(hào)的部分。
2. synapse(突觸):神經(jīng)元之間的連接點(diǎn),是信號(hào)從一個(gè)神經(jīng)元傳遞到另一個(gè)神經(jīng)元的地方。
3. dendrotoxin(毒蛋白):一種從蛇毒中提取的蛋白質(zhì),具有神經(jīng)毒性,對(duì)神經(jīng)細(xì)胞有破壞作用。
4. entorhinal cortex(內(nèi)嗅皮質(zhì)):位于大腦的一個(gè)區(qū)域,與記憶和情緒等高級(jí)認(rèn)知過程有關(guān),與dendrite(樹突)同詞根,同源。
5. dendritic spines(樹突棘):在樹突上的一些特殊結(jié)構(gòu),與神經(jīng)元的接收和傳遞信號(hào)有關(guān)。
6. dendritic development(樹突發(fā)育):指神經(jīng)元樹突的生長(zhǎng)和發(fā)育過程。
7. dendritic synapses(樹突突觸):指發(fā)生在樹突上的突觸。
8. dendritic plasticity(樹突可塑性):指神經(jīng)元樹突對(duì)刺激的反應(yīng)性變化,與學(xué)習(xí)和記憶等認(rèn)知過程有關(guān)。
9. dendritic computation(樹突計(jì)算):指在樹突上進(jìn)行的信息處理,與神經(jīng)計(jì)算和人工智能等領(lǐng)域有關(guān)。
10. dendritic ion channels(樹突離子通道):指在樹突膜上的離子通道,控制著樹突內(nèi)的離子濃度,影響神經(jīng)元的興奮性和傳導(dǎo)性。
dendrites相關(guān)的常用短語(yǔ):
1. dendrite growth 樹突增長(zhǎng)
2. axon-dendrite interaction 軸突樹突相互作用
3. dendritic spines 樹突棘
4. dendritic development 樹突發(fā)育
5. dendritic morphology 樹突形態(tài)
6. dendritic synapses 樹突突觸
7. dendritic spine density 樹突棘密度
雙語(yǔ)例句:
1. The growth of dendrites is crucial for the development of the nervous system. (樹突的增長(zhǎng)對(duì)于神經(jīng)系統(tǒng)的發(fā)展至關(guān)重要。)
2. The axon-dendrite interaction between neurons is essential for information processing in the brain. (神經(jīng)元之間的軸突樹突相互作用對(duì)于大腦的信息處理至關(guān)重要。)
3. Dendrites are the input terminals of neurons that receive signals from other neurons and environmental stimuli. (樹突是神經(jīng)元的輸入終端,接收來(lái)自其他神經(jīng)元和環(huán)境刺激的信號(hào)。)
4. Dendritic spines are important for synaptic transmission and are targets for drugs designed to treat mental illnesses. (樹突棘對(duì)于突觸傳遞至關(guān)重要,是設(shè)計(jì)用于治療精神疾病的藥物的靶點(diǎn)。)
5. Dendritic morphology varies between neurons and is influenced by their environment, making it difficult to compare them directly. (樹突形態(tài)在神經(jīng)元之間存在差異,并受到其環(huán)境的影響,因此很難直接進(jìn)行比較。)
6. Dendritic synapses are crucial for information storage and processing in the brain, and are targets for drugs designed to enhance cognitive function. (樹突突觸對(duì)于大腦中的信息儲(chǔ)存和處理至關(guān)重要,是增強(qiáng)認(rèn)知功能藥物的靶點(diǎn)。)
7. The density of dendritic spines varies between individuals, and may be influenced by genetics, environment, and disease processes. (樹突棘密度的變化因人而異,可能受到遺傳、環(huán)境以及疾病進(jìn)程的影響。)
英文小作文:
Neurons are the basic units of the brain that process information and send signals to other neurons and body parts. Dendrites are extensions of neurons that receive signals from other neurons and environmental stimuli, and help transmit these signals to the cell body. Dendritic spines are specialized regions on dendrites that are important for synaptic transmission and are targets for drugs designed to treat mental illnesses. However, dendritic morphology varies between individuals and is influenced by genetics, environment, and disease processes, making it difficult to compare them directly. Understanding the role of dendrites in information processing and communication between neurons is crucial for developing effective treatments for neurological disorders.
