What is the function of Nissl granules?
Answer: (1) Nissl’s Granules are the substances found in the neurons which are a large granular type of body. These granules are very useful for protein synthesis also help to transport these proteins to the part known as cyton.
What is the meaning of Nissl granules?
Nissl granules (Nissl bodies) Particles seen within the cell bodies of neurons, consisting of granular endoplasmic reticulum and polyribosomes. They are rich in RNA and stain strongly with basic dyes. They are named after F. Nissl (1860–1919), the German neurologist who discovered them. A Dictionary of Biology.
Where are Nissl granules absent?
Axon
Explanation: Nissl granules are absent in Axon. The neuron is made up of a cell body (cyton), dendrites (dendron), axons and axon terminals. Nissl granules are discrete structures, which consist rough endoplasmic reticulum and free ribosomes.
Where are Nissl granules present?
Nissl’s granules are present only in the cytoplasm of the cell body of neurons. Complete answer: These granules are rough endoplasmic reticulum with rosettes of free ribosomes that synthesize proteins in the body of the neuron.
What is the function of Nissl Chromatophilic bodies?
What is the function of Nissl (chromatophilic) bodies? They continually renew cell membranes and proteins of the cytosol.
What is Nissl bodies in anatomy?
Medical Definition of Nissl bodies : discrete granular bodies of variable size that occur in the cell body and dendrites but not the axon of neurons, are composed of RNA and polyribosomes, are stained with basic dyes (as methylene blue), and give a striped appearance to the cell.
What are the Nissl bodies?
Subcellular structures found in nerve cell bodies and DENDRITES. They consist of granular endoplasmic reticulum (ENDOPLASMIC RETICULUM, ROUGH) and RIBOSOMES.
What are Nissl bodies quizlet?
Nissl bodies. a large granular body found in neurons. These granules are of rough endoplasmic reticulum (RER) with rosettes of free ribosomes, and are the site of protein synthesis. -Located on the SOMA of a neuron. The trigger zone of a neuron.
What are Nissl’s granules made up of?
The Nissl granules of nerve cells are made up of (a)Ribosome (b)Protein (c)DNA (d)Mitochondria
- Hint: Nissl granules are made up of substances that are usually present over the rough endoplasmic reticulum and in the cytoplasm.
- Complete answer:
- Additional Information:
- So, the correct answer is, ‘ Ribosome.
What is the composition of Nissl granules?
Nissl body is also called as nissl substance. It is a large granular body present in neurons. Their main function is to synthesize and release proteins that are important for neuronal growth and regeneration of axons. It is made up of rough endoplasmic reticulum (RER) and free ribosomes.
What are nissl bodies made of?
In which part of the neuron would the nissl bodies be found quizlet?
Where in the neuron can we find nissl bodies? Only in the soma and dendrites — it cannot pass the axon hillock. Where can mitochondria be found? Throughout the neuron — they are essential at the pre-synaptic membrane because they provide energy for the secretory vessels.
What are Nissl’s bodies?
Subcellular structures found in nerve cell bodies and DENDRITES. They consist of granular endoplasmic reticulum (ENDOPLASMIC RETICULUM, ROUGH) and RIBOSOMES. Year introduced: 1965(1964)

What are Nissl granules?
Nissl granules (Nissl bodies) Particles seen within the cell bodies of neurons, consisting of granular endoplasmic reticulum and polyribosomes.

What is the function of Nissl bodies?
They consist of clusters of rough endoplasmic reticles. This structure exists only in cells that have nuclei, such as neurons. The bodies of Nissl serve, mainly, to synthesize and to release proteins. These are essential for neuronal growth and regeneration of axons in the peripheral nervous system.
What is the function of the spleen?
The spleen participates in the creation of blood cells and also helps to filter out the blood, removing old blood cells and fighting infection.
Why is the spleen not a necessary organ?
As a spleen becomes enlarged, it becomes more fragile and is more likely to be damaged in an accident. As the spleen is not the only organ responsible for any of these functions, the spleen is not a necessary organ. It is possible to have the spleen removed and live a healthy life.
