Recall that the Golgi apparatus is responsible for the packaging of the proteins. They are present in the form of clumps of basophilic material known as Nissl substance or Nissl bodies. The cell body appears to be highly basophilic in the regions containing rough endoplasmic reticulum and associated polyribosomes. They can make multiple copies of a polypeptide at the same time. A large number of parallel cisternae of the reticulum are present close to the nucleus associated with polyribosomes (a group of ribosomes attached to a single copy of mRNA). It has a highly developed system of rough endoplasmic reticulum for making proteins. The cell body of the neurons is responsible for protein synthesis. The fine chromatin threads can also be visualized within the nucleus. In most of the cells, the nucleus is pale-staining that indicates the euchromatic nature of chromatin. Most neurons have a large spherical central nucleus having a prominent nucleolus.
The nucleus occupies is present in the central portion of the cell body of neurons. These include the Golgi apparatus and the endoplasmic reticulum.Ī brief detail of the major organelles found in the cell body is as follows. The major organelles are also present in the cell body or perikaryon. It is the region that contains the nucleus and the surrounding cytoplasm. The cell body of a neuron serves as the synthetic or trophic center for the entire cell. In this section, we will talk about the basic structure of neurons found in the brain.Ī neuron can be divided into three basic parts cell body or perikaryon, axons, and dendrites. Structure of NeuronĪlthough different types of neurons are present in the brain, the basic structure of all the neurons is always the same.
Besides, we will be discussing different types of synapses and their role in the brain. We will also discuss the role of glial cells in the brain. In this article, we will talk about different types of neurons present in the brain, the structure, and functions of these neurons as well as the way they are connected. In addition to the neurons, supporting cells called the neuroglial cells are also present in the brain. These neurons are connected via special links called synapses. different types of neurons are present in the brain. Neurons are the basic structural and functional units of the nervous system. It is also responsible for higher functions such as thought processing, memory formation, behavior, thinking, etc.Īll these functions in the brain are performed by neurons. In addition, it also has control systems for the regulation of involuntary processes like respiratory rate, blood pressure, etc.
It controls all the voluntary activities performed by a person. It is the main component of the central nervous system. Brain is the central control system of the body.
