脑神经 （英語： cranial nerve），又称 颅神经，属于 周围神经系统，它们是直接由 脑 发出的，区别于由 脊髓 发出的 脊神经 [1][2]。 脑神经在脑和身体各部分之间传递信息，主要是往返于头部和颈部的区域，包括视觉、味觉、嗅觉和听觉等 特殊感觉 [3]。 部分脑神经属于 传出神经，部分为 传入神经，其余的为混合神经（同时含有 传出神经纤维 和 传入神经纤维） [1][2]。 在人体中，传统上认为一共有12对脑神经，其中有10对分布于头面部 [1]；除第1及第2对外，其余10对脑神 …

2023年2月7日 · Your cranial nerves are pairs of nerves that connect your brain to different parts of your head, neck, and trunk. There are 12 of them, each named for its function or structure.

Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing. [1]

2024年8月15日 · Your cranial nerves are a set of 12 paired nerves that stem from your brain. They have a wide variety of functions, including helping you see, taste, smell, hear and feel sensations. They also help you make facial expressions, blink your eyes and move your tongue.

2023年11月3日 · Cranial nerves are the 12 nerves of the peripheral nervous system that emerge from the foramina and fissures of the cranium. Their numerical order (1-12) is determined by their skull exit location (rostral to caudal). All cranial nerves originate from nuclei in the brain.

6 天之前 · The cranial nerves are a set of 12 paired nerves that arise directly from the brain. The first two (olfactory and optic) arise from the cerebrum, whereas the remaining ten emerge from the brain stem. The names of the cranial nerves relate to their function and are numerically identified in roman numerals (I-XII).

2025年1月24日 · Unlike spinal nerves, whose roots are neural fibers from the spinal grey matter, cranial nerves are composed of the neural processes associated with distinct brainstem nuclei and cortical structures. Unlike the spinal nerves, cranial nerve nuclei are functionally organized into distinct nuclei within the brainstem.

The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular …

2025年1月22日 · These nerve pairs serve a range of functions: transmitting sensory information, controlling face, head, and neck muscle movements, and relaying information to internal organs to regulate functions like blood pressure and heart rate. Get to know the brain’s 12 cranial nerves using the 3D Brain. Then, review your knowledge of them with these ...

2018年7月15日 · The nerves that arise from the brain and supply to the head, neck and face are called cranial nerves. There are 12 pairs of cranial nerves which are the parts of peripheral nervous system. Their names are an indication of some of their anatomical or functional features, and their numbers (Roman numerals) indicate the sequential order in which ...
