神经元的胞体（soma）在于脑和脊髓的灰质及神经节内，其形态各异，常见的形态为星形、锥体形、梨形和圆球形状等。胞体大小不一，直径在5～150μm（微米）之间。胞体是神经元的代谢和营养中心。（l）细胞膜:胞体的胞膜和突起表面的膜，是连续完整的细胞膜。除突触部位的胞膜有特异的结构外，大部分胞膜为单位膜结构。神经细胞膜的特点是一个敏感而易兴奋的膜，在膜上有各种受体和离子通道，二者各由不同的膜蛋白所构成。形成突触部分的细胞膜增厚。膜上受体可与相应的病毒学物质神经递质结合。当受体与乙酰胆碱递质或γ-氨基丁酸递质结合时，膜的离子通透性及膜内外电位差发生改变，胞膜产生相应的生理活动：兴奋或抑制。

（2）细胞核：多位于神经细胞体中央，大而圆，异染色质少，多位于核膜内侧，常染色质多，散在于核的中部，故着色浅，核仁l～2个，大而明显。细胞变性时，核多移向周边而偏位。
（3）细胞质：位于核的周围，又称核周体，其中含有发达的高尔基复合体、滑面内质网，丰富的线粒体、尼氏体及神经原纤维，还含有溶酶体、脂褐素等结构。具有分泌功能的神经元，胞质内还含有分泌颗粒，如位于下丘脑的一些神经元。
l）尼氏体:又称嗜染质，是胞质内的一种嗜碱性物质，在一般染色中岛被碱性染料所染色，多呈斑块状或颗粒状。它分布在核周体和树突内，而轴突起始段的轴丘和轴突内均无。依神经元的类型和不同生理状态，尼氏体的数量、形状和分布也有所差别。典型的如脊髓前角运动神经元，尼氏体数量zui多，呈斑块状，分散于神经原纤维之间，有如虎皮样花斑，故又称虎斑小体。而在脊神经节神经元的胞质内，尼氏体呈颗粒状，散在分布。
电镜下，尼氏体是由许多发达的平行排列前粗面内质网及其间的游离核糖体组成。
The soma of neurons lies in the gray matter and ganglia in the brain and spinal cord, and their shapes are different. Common shapes are star, cone, pear and ball. Cell body size varies between 5 ~ 150μm (microns) in diameter. The soma is the neuronal metabolic and nutritional center. (L) Cell membrane: membrane of the cell body and the membrane surface of the protrusion, is a continuous complete cell membrane. In addition to the synaptic membrane specific structure, most of the membrane for the unit membrane structure. The neuronal cell membrane is characterized by a sensitive and easily excitable membrane with various receptors and ion channels on the membrane, each consisting of different membrane proteins. The synapses form thicker cell membranes. Membrane receptors can be associated with the corresponding virologic neurotransmitter. When the receptor and acetylcholine transmitter or γ-aminobutyric acid neurotransmitter binding, membrane ion permeability and potential difference between the membrane changes, the membrane produce the corresponding physiological activity: excitement or inhibition.

(2) nucleus: mostly located in the central nerve cell body, large and round, less heterochromatin, mostly in the medial nuclear membrane, often more chromatin, scattered in the middle of the nucleus, it is pale, nucleolus l ~ 2, large And obviously. Cells degeneration, the nuclear shift to the periphery and the deviation.
(3) cytoplasm: located around the nucleus, also known as the perinuclear body, which contains the developed Golgi complex, smooth surface endoplasmic reticulum, abundant mitochondria, Nissl body and neurofibrils, also contains lysosomes, fat brown Vegetarian and other structures. Secretory function of neurons, the cytoplasm also contains secretory granules, such as in the hypothalamus of some neurons.
l) Nisshin: also known as eosinophils, cytoplasm is a kind of basophilic substances, in the general staining of the island was dyed with alkaline dyes, mostly plaque or granular. It is located in the perinuclear and dendrites, and axons at the beginning of the shaft mound and axon are not. According to the type of neurons and different physiological states, the number, shape and distribution of Nisshin also vary. Typical such as spinal motor anterior horn motor neurons, Nisshin the largest number, was plaque, scattered between the neurofibrils, such as tiger-like plaque, it is also known as the tiger body. In the spinal ganglion neurons cytoplasm, Niger body was granular, scattered distribution.
Under electron microscopy, Nissl body is composed of many developed parallel arrangement of rough rough endoplasmic reticulum and the free ribosome in between.
