延髓與呼吸有關(guān)的神經(jīng)元可分為兩組:一部分集 中在孤束核的腹外側(cè)部,叫做背側(cè)呼吸組。孤束核區(qū)是吸氣神經(jīng)元(I )密集的部位(I中又分為Iα和Iβ兩類神經(jīng)元)。呼氣神經(jīng)元(E) 只占4~5 %。背側(cè)組的吸氣神經(jīng)元發(fā)出軸突在閂前交叉,支配對側(cè)隔 肌運(yùn)動神經(jīng)元;它是驅(qū)動腹側(cè)呼吸組及脊髓膈肌運(yùn)動神經(jīng)元的呼吸節(jié) 律的發(fā)源部位。腹側(cè)呼吸組的呼吸神經(jīng)元在延髓腹外側(cè)都,集中在疑 核和后疑核,從閂部前方迷走神經(jīng)根水平向下延伸至*頸髓處,呈 縱向排列。疑核中有吸氣及呼氣兩種神經(jīng)元,軸突走行于同側(cè)迷走神 經(jīng)、舌咽神經(jīng)中,支配咽部的輔助呼吸,在閂處交叉,與胸段脊髓肋 間外肌運(yùn)動神經(jīng)元發(fā)生,其中又有25 %與膈神經(jīng)元有側(cè)枝。 因之延髓呼吸神經(jīng)元對呼吸肌的支配是對側(cè)性的(見腦橋、呼吸)。 延髓對呼吸的調(diào)節(jié)除神經(jīng)途徑外,另一條是靠對血液中pH值和CO2 濃 度的變化的反應(yīng)。延髓腹外側(cè)的表淺部位有化學(xué)敏感細(xì)胞,叫做中樞 化學(xué)感受器,它們感受化學(xué)性刺激(特別是氫離子濃度的變化)。當(dāng) 延髓局部CO2濃度增加或pH值下降時,這些神經(jīng)細(xì)胞的膜電位下降或放 電頻率增加。它們對腦脊液中氫離子濃度的變化也很敏感。CO2易通過 血腦屏障進(jìn)入腦脊液,與化學(xué)敏感細(xì)胞周圍的細(xì)胞液中的水分結(jié)合成 碳酸,再離解出氫離子,使腦脊液的氫離子濃度隨之升高,從而刺激 延髓中樞化學(xué)感受器的敏感細(xì)胞,使呼吸增強(qiáng);把過多的CO2及時排出 體外。髓鞘是包裹在神經(jīng)細(xì)胞軸突外面的一層膜,即髓鞘由施旺細(xì)胞 和髓鞘細(xì)胞膜組成。其作用是絕緣,防止神經(jīng)電沖動從神經(jīng)元軸突傳 遞至另一神經(jīng)元軸突。髓鞘一般只出現(xiàn)在脊椎動物以及一些橈腳類動 物的神經(jīng)元軸突外圍。目前研究注意髓鞘成分的抗原性,如:髓鞘堿 性蛋白(MBP)、髓鞘相關(guān)醣蛋白(MAG)、髓鞘少突膠質(zhì)細(xì)胞醣蛋白 (MOG)等。髓鞘(myelin sheath)指包圍有鞘神經(jīng)纖維軸中間那層黃 色的就是髓鞘中間那層黃色的就是髓鞘索的管狀外膜,由髓磷脂構(gòu)成 ,故又稱髓磷脂鞘。
The medulla oblongata and respiration-related neurons can be divided into two groups: one is concentrated in the ventrolateral part of the solitary nucleus, called the dorsal respiratory group. The solitary tract nucleus region is the site where inspiratory neurons (I) are dense (I is divided into two types of neurons: Iα and Iβ). Expiratory neurons (E) account for only 4 to 5%. The inspiratory neurons of the dorsal group emit axons that cross at the latch and govern the contralateral septal motoneurons; it is the site of origin of the respiratory rhythm that drives the ventral respiratory group and the dorsal moto motoneurons. In the ventral respiratory group, the respiratory neurons were located in the rostral ventrolateral medulla and concentrated in the skeletal and posterior suspected nucleus. The vagus nerve roots were located horizontally from the front of the latch to the first cervical cord. There are two kinds of neurons inspiration and exhalation in the suspected nucleus. The axon runs in the ipsilateral vagus nerve, glossopharyngeal nerve, and the auxiliary breathing of the dominant pharynx. It intersects with the occipital spine and intercostal muscles of the thoracic spinal cord. In contact, 25% of them had collateral connections with the phrenic neurons. Because of the medullary respiratory neurons, the control of respiratory muscles is contralateral (see pons, breathing). The regulation of respiration by the bulbar medulla, in addition to the nerve pathway, is based on a response to changes in the pH and CO2 concentration in the blood. The superficial part of the rostral ventrolateral medulla has chemically sensitive cells called central chemoreceptors that sense chemical stimuli (especially changes in hydrogen ion concentration). When the CO2 concentration in the medulla oblongata increases or the pH value decreases, the membrane potential of these nerve cells decreases or the frequency of discharge increases. They are also sensitive to changes in the concentration of hydrogen ions in the cerebrospinal fluid. CO2 easily enters the cerebrospinal fluid through the blood-brain barrier, and combines with the water in the cytosol surrounding the chemically sensitive cells to form carbonic acid, and then dissociates hydrogen ions to increase the concentration of hydrogen ions in the cerebrospinal fluid, thereby stimulating sensitive cells in the medullary nucleus chemoreceptors. Enhance breathing; remove excess CO2 from the body in time. Myelin sheath is a membrane that wraps around the axon of nerve cells, ie myelin is composed of Schwann cells and myelin cell membranes. Its role is to insulate and prevent nerve electrical impulses from being transmitted from neuronal axons to axon of another neuron. Myelin sheaths usually only appear in the periphery of axons of vertebrates and some copepod-like neurons. At present, attention is paid to the antigenicity of myelin components, such as myelin basic protein (MBP), myelin-associated glycoprotein (MAG), and myelin oligodendrocyte glycoprotein (MOG). Myelin sheath (myelin sheath) refers to the yellow layer that surrounds the middle layer of the sheath nerve fiber. The middle layer of yellow myelin sheath is the tubular outer membrane of myelin sheath. It is composed of myelin and is also called myelin sheath.
