Lateral corticospinal tract

Japanese: 外側皮質脊髄路 - がいそくひしつせきずいろ

…Today, it is customary to write the origin and termination of a pathway, so the pyramidal tract is written as the corticospinal tract. The pyramidal lateral tract and the prepyramidal tract are called the lateral corticospinal tract and the anterior corticospinal tract, respectively, but these are literal translations of the Latin names and are somewhat difficult to understand. On the other hand, the motor neurons that control the striated muscles of the head, such as the extraocular muscles, the muscles of mastication, the muscles of facial expression, the small muscles of the pharynx and larynx, and the tongue, are located in the cranial nerve origin nuclei distributed from the midbrain to the medulla oblongata. …

From [Spinal Cord]

…It descends from the motor cortex in the frontal lobe of the cerebrum, connects with motor cells in the anterior horn along the entire length of the spinal cord. At the lower end of the medulla oblongata, most of this tract crosses (pyramidal decussation) and descends to the lateral funiculus on the opposite side to become the lateral corticospinal tract. The remainder does not cross and descends to the anterior corticospinal tract on the same side to become the anterior corticospinal tract. …

*Some of the terms that refer to the "lateral corticospinal tract" are listed below.

…今日では伝導路は起始と終止を併記する慣例になっているので，錐体路は皮質脊髄路と表記される。また錐体側索路，錐体前索路はそれぞれ外側皮質脊髄路，前皮質脊髄路となっているが，これはラテン学名の直訳でいささかわかりづらい。　一方，外眼筋，咀嚼（そしやく）筋，表情筋，咽頭･喉頭の小筋，舌筋などの頭部の横紋筋を支配する運動神経細胞は，中脳から延髄にかけて分布する脳神経起始核にある。…
