";s:4:"text";s:3914:" ( B ) ARS group; pleopathologic changes of most of pyramidal neurons’ nuclei as well as vacuolated cytoplasm (V). The main function of these ribosomes is protien synthesis and therefore nissl granules help in protien synthesis and provides protiens to the cyton. Nissl substance: ( nis'ĕl ), the material consisting of granular endoplasmic reticulum and ribosomes that occurs in nerve cell bodies and dendrites. Nissl Bodies are granules of endoplasmic reticulum, with aggregations of fixed or free Ribosomes and are the site of protein synthesis. The soma of a neuron (i.e., the main part of the neuron in which the dendrites branch off of) contains many organelles, including granules called Nissl granules, which are composed largely of rough endoplasmic reticulum and free polyribosomes. They are rich in RNA and stain strongly with basic dyes. Nissl granules (Nissl bodies) Particles seen within the cell bodies of neurons, consisting of granular endoplasmic reticulum and polyribosomes. Neurons with long axons are called as. Function: to transmit electrical impulses around the body so that the organism can respond to changes in its internal and external environment. [2] [1] It was named after Franz Nissl, a German neuropathologist who invented the Nissl staining method. Synonym(s): basophil substance , basophilic substance , chromophil substance , Nissl bodies , Nissl granules , substantia basophilia , tigroid bodies , … Nissl granules are actually rough endoplasmic reticulum and they are called rough due to the presence of ribosomes in its walls. 3 mins read.

Nissl's Granules - if a portion of the brain or spinal cord are fixed in absolute alcohol, and sectioned obtained from the hardened pieces are stained with methylene blue, the nerve cells exhibit a characteristic appearance. Synonym(s): basophil substance , basophilic substance , chromophil substance , Nissl bodies , Nissl granules , substantia basophilia , tigroid bodies , …
The cell nucleus is a key feature of the soma. The main function of Nissl bodies within neurons is to aid in the production and dispersal of chemical substances such as proteins and peptides, as illustrated by Richard F. Thompson in his book "The Brain: A Neuroscience Primer." Nissl granules are actually rough endoplasmic reticulum and they are called rough due to the presence of ribosomes in its walls. 2 mins read. View Answer. Types of Neurons on the basis of No. 1 Verified Answer. The structure of Nissl bodies makes them particularly adept at protein synthesis, an essential cellular process within a neuron. Nissl substance: ( nis'ĕl ), the material consisting of granular endoplasmic reticulum and ribosomes that occurs in nerve cell bodies and dendrites. Nissl bodies (chromatin granules), intensely basophilic and stained by cresyl violet and similar dyes, occupy the perikaryon and dendrites but not the axon hillock (Figs 2.1 and 2.3).They are more prominent in motor than in sensory neurons, amounts varying with cell activity. the nucleus and nucleolus take up the blue stain.
