What is the function of the Nissl bodies?

The functions of Nissl bodies are thought to be the same as those of the rough endoplasmic reticulum in general, primarily the synthesis and segregation of proteins. Similar to the ergastoplasm of glandular cells, Nissl bodies are the main site of protein synthesis in the neuronal cytoplasm.

What are Nissl bodies quizlet?

Nissl Bodies (Definition) Large aggregation of RER and free polysomes arranged in alternating layers. These are the only subcellular structures visible in light micrographs of neurons. You just studied 54 terms!

Can you hypothesize why Nissl bodies exist in neurons and not in other cells?

Can you hypothesize why Nissl bodies exist in neurons and not in other cells? Nissl bodies make and release proteins for the neuron. A neuroglia cell does not have an axon or dendrites like a neuron. A neuroglia cells helps the neuron by producing myelin sheath that anchor neurons, become phagocytes, and release fluid.

What is the function of the cell body quizlet?

The cell body, also called the soma, is the spherical part of the neuron that contains the nucleus and holds all of the general parts of the cell. The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.

What do Nissl bodies look like?

Floating in the cytoplasm of the cell body are irregularly shaped particles called “Nissl bodies”, scientists think that they are responsible for assembling proteins. The cytoplasm is filled with small tubes called microtubules. Scientists think that these tubes carry proteins and other substances through the cell.

What is the function of Neurofibril?

neurofibril Any of the fibres in the cytoplasm of a nerve axon. Neurofibrils include neurofilaments and neurotubules, microtubules that play a role in the transport of proteins and other substances within the cytoplasm.

What do nissl bodies look like?

Where are nissl bodies located?

Subcellular structures found in nerve cell bodies and DENDRITES. They consist of granular endoplasmic reticulum (ENDOPLASMIC RETICULUM, ROUGH) and RIBOSOMES.

What distinguishes a neuron from a Neuroglia cell?

Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses. Neuroglia are supporting cells that provide physical sport, remove debris, and provide electrical insulation.

What is the function of the axon quizlet?

Axons: Conduct nerve impulses away from the cell body towards: the dendrites or cell body of another neuron or an effector (muscle or gland).

What is the primary function of the myelin sheath?

Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells.
