Which of following organelles is a common site of protein synthesis in neurons?

What organelle is a common site of protein synthesis?

A ribosome is an organelle that serves as the site of protein synthesis. It is composed of two ribosomal RNA subunits that wrap around mRNA to start the process of translation, followed by protein synthesis. Smooth ER (SER) lacks these ribosomes .

Which of the following types of neurons is most common in brain?

Interneurons (association) – provide communication between sensory and motor neurons . Involved in learning and memory. Most common type of neuron ; found in the brain and spinal cord.

Which type of central nervous system tissue contains neuronal cell bodies?

Gray matter is a major component of the CNS, it refers to un-myelinated neurons and other cells of the central nervous system such as glial cells and dendrites. It is present in the brain, brainstem and cerebellum, and present throughout the spinal cord. Gray matter contains most of the brain’s neuronal cell bodies.

Which type of neuron is exclusively found in the cerebellum?

Technically, the output of the cerebellum is exclusively inhibitory through the Purkinje neurons onto the cerebellar nuclei, but the cerebellar nucleus exerts both excitatory and inhibitory influences, on the thalamus and on the Inferior Olive, respectively (Ruigrok and Voogd, 1995).

What is the list of organelles that take part in protein synthesis?

Cell organelles that participate in protein synthesis are golgi bodies, ribosomes and endoplasmic reticulum.

What cell packages proteins?

Among the many parts of a cell , the Golgi apparatus performs this job. It modifies and packages proteins and lipids made within the cell , and sends them out to where they are needed.

What are the 3 major types of neurons?

For the spinal cord though, we can say that there are three types of neurons : sensory, motor, and interneurons. Sensory neurons . Motor neurons . Interneurons. Neurons in the brain.

Which type of neuron is most common?

Multipolar neurons are the most common neuron in the vertebrate nervous system and their structure most closely matches that of the model neuron: a cell body from which emerges a single long axon as well as a crown of many shorter branching dendrites.

What type of neurons are in the brain?

There are three major types of neurons : sensory neurons , motor neurons , and interneurons. All three have different functions, but the brain needs all of them to communicate effectively with the rest of the body (and vice versa).

Where is nervous tissue found?

Nervous tissue is found in the brain , spinal cord , and nerves. It is responsible for coordinating and controlling many body activities.

Which organ is formed by nervous tissue?

Nervous tissue is the main component of the nervous system, which includes the brain , spinal cord, and nerves .

What are the 3 types of nervous tissue?

Neurons , or nerves, transmit electrical impulses, while neuroglia do not; neuroglia have many other functions including supporting and protecting neurons .

Are sensory neurons bipolar?

A bipolar neuron , or bipolar cell, is a type of neuron that has two extensions (one axon and one dendrite). Many bipolar cells are specialized sensory neurons for the transmission of sense. As such, they are part of the sensory pathways for smell, sight, taste, hearing, touch, balance and proprioception.

Are Purkinje cells bipolar?

This suggests that virus-mediated abnormal Purkinje cell function may be linked to bipolar disorder and major depression in some cases. An analysis of brain tissue in the cerebellum using gene expression techniques also revealed an inflammatory response to HHV-6A infection.

Are neurons found in any other part of the human body?

Neurons are cells within the nervous system that transmit information to other nerve cells , muscle, or gland cells. Most neurons have a cell body , an axon, and dendrites. The cell body contains the nucleus and cytoplasm. The cell body contains the nucleus and cytoplasm.
