呼吸中樞 （respiratory center）是指中樞神經(jīng)系統(tǒng)內(nèi)產(chǎn)生呼吸節(jié)律和調(diào)節(jié)呼 吸運動的神經(jīng)細胞。在對呼吸中樞定位研究的諸多實驗中，具有重要 價值的是1923年由英國的生理學(xué)家拉姆斯登（Lumsden）對貓的腦干 進行的分段橫切實驗。呼吸中樞分布在大腦皮層、間腦、腦橋、延髓 和脊髓等各級部位，參與呼吸節(jié)律的產(chǎn)生和調(diào)節(jié)，共同實現(xiàn)機體的正 常呼吸運動。延髓呼吸中樞具有內(nèi)在節(jié)律活動，在整體內(nèi)，吸氣神經(jīng) 元能發(fā)放陣發(fā)性的成簇電位，每分鐘12~15次，與呼吸頻率相似，而呼 氣神經(jīng)元無自發(fā)性放電。如果在貓的延髓與脊髓之間橫斷脊髓，其自 主節(jié)律性呼吸立即停止且不能恢復(fù)，提示脊髓不能產(chǎn)生自動的節(jié)律性 呼吸。但支配呼吸肌的下運動神經(jīng)元位于脊髓，說明脊髓是腦和 呼吸肌的中繼站以及整合某些呼吸反射的初級中樞。[1] 脊髓頸、胸 節(jié)段灰質(zhì)前角有呼吸運動神經(jīng)元。頸3~5節(jié)有支配膈肌的神經(jīng)元。脊髓 胸段2~6節(jié)有支配肋間肌的運動神經(jīng)元。如把脊髓在胸段第6節(jié)以下橫 斷，對呼吸運動將不發(fā)生任何妨礙。如把脊髓在頸段第6節(jié)以下橫斷， 肋間肌雖已失去作用，但膈肌還能照常進行有節(jié)律收縮活動；只有把 脊髓在頸段第2節(jié)水平切斷，呼吸肌由于與延髓中樞分離而不再起作用 。延髓中有產(chǎn)生節(jié)律性呼吸的基本中樞，兩部位有部分重在腦干不同 平面橫切時引起的呼吸變化在腦干不同平面橫切時引起的呼吸變化疊 ，如刺激呼氣中樞，引起持續(xù)呼氣動作；刺激吸氣中樞，引起持續(xù)吸 氣動作；交替刺激兩個部位，可引起相應(yīng)呼氣和吸氣交替出現(xiàn)。吸氣 中樞更敏感。其中樞神經(jīng)細胞，一為背側(cè)，包括附近的孤束核，為吸 氣神經(jīng)元，自動發(fā)出沖動，作用于脊髓對側(cè)的膈肌運動神經(jīng)元，從而 引起對側(cè)膈肌收縮，又作用于腹外側(cè)疑核，通過迷走神經(jīng)和舌咽神經(jīng) 支配同側(cè)呼吸輔助肌，后疑核支配肋間肌運動神經(jīng)元。延髓中樞與脊 髓之間具交互抑制現(xiàn)象。延髓的吸氣神經(jīng)元可通過下行路徑引起脊髓 吸氣肌運動神經(jīng)元興奮，同時又有側(cè)支通過抑制性中間神經(jīng)元對脊髓 呼氣肌運動神經(jīng)元起抑制作用。
Respiratory center refers to the nerve cells in the central nervous system that produce respiratory rhythms and regulate respiratory movements. Among the many experiments on the positioning of respiratory centers, it was of great importance in 1923 that the British physiologist Lumsden conducted a segmental cross-cut experiment on the cat's brainstem. The respiratory center is distributed in various parts of the cerebral cortex, diencephalon, pons, medulla, and spinal cord. It participates in the generation and regulation of respiratory rhythm and achieves the normal respiratory movement of the body. The medullary respiratory center has intrinsic rhythmic activity. In the whole, the inspiratory neurons can deliver paroxysmal clustering potentials 12 to 15 times per minute, similar to the respiratory rate, and the expiratory neurons do not have spontaneous discharge. If the spinal cord is tran- sected between the medulla oblongata and the spinal cord of the cat, its spontaneous rhythmic breathing stops immediay and cannot be recovered, suggesting that the spinal cord cannot produce automatic rhythmic breathing. However, the lower motor neurons that dominate the respiratory muscles are located in the spinal cord, indicating that the spinal cord is a relay station that connects the brain and respiratory muscles and a primary center that integrates certain respiratory reflexes. [1] There are respiratory motor neurons in the anterior horn of the cervical spine and thoracic segments. Neck 3 to 5 have neurons that dominate the diaphragm. The thoracic segments 2-6 have motoneurons that dominate the intercostal muscles. If the spinal cord is transection below section 6 of the thoracic segment, there will be no hindrance to respiratory motion. If the spinal cord is transected below the sixth segment of the cervical septum, although the intercostal muscle has lost its function, the diaphragm muscle can perform rhythmic contraction as usual; only when the spinal cord is cut at the level of the second cervical segment, the respiratory muscle is separated from the medulla oblongata It no longer works. In the medulla oblongata, there is a basic center of rhythmic breathing, and some parts of the medulla produce a rhythmic respiration, and some of the two parts are heavy in the breathing changes caused when the brainstem is cut in different planes, and the breathing changes caused when the brainstem is cut in different planes, such as stimulation of the exhalation center, causing continuation Exhale movements; stimulating the inspiratory center, causing continuous inhalation; alternay stimulating two sites, can cause the corresponding exhalation and inhalation to appear alternay. Inhalation centers are more sensitive. The central nerve cells, one is dorsal, including the nearby nucleus of solitary tract, are inspiratory neurons, automatically emit impulses, act on the diaphragm muscle motor neurons on the contralateral side of the spinal cord, causing contraction of the contralateral diaphragm, but also on the ventrolateral Suspected nucleus, the vagus nerve and glossopharyngeal nerve innervate the ipsilateral respiratory accessory muscle, and the postnucleus suspects the intercostal muscle motor neurons. There is an interaction between the medulla oblongata and the spinal cord. The inspiratory neurons of the medulla oblongata can cause excitation of spinal inspiratory muscle motor neurons through the descending pathway, and at the same time, there are collaterals inhibiting the spinal expansive motor neurons through inhibitory interneurons.
