In summary, there is myelin present in the human brain, although not from the beginning. However, not all nerve fibers are covered by myelin. In addition to nerve cells, there are also other cells and tissues present in the brain, such as immune cells and extracellular matrix.

Hello everyone,

I know nerve fibres inside brain are not covered by perineurium etc like Peripheral nervous system. Are they still covered with connective tissue, support cells, myelin etc. I mean inside the brain , a collection of nerve fibres, how are they held together with no connective tissue. I don't have much knowledge about brain. Thanks :smile:

It is there
Not for all fibers. For most, though.

There is a lot more in the brain than just nerve cells, if that's what you're getting at. Immune cells, vascular cells, extracellular matrix, ...

Hello,

Thank you for your question. The nerve fibers in the brain are indeed covered by connective tissue, support cells, and myelin. The connective tissue in the brain is called the meninges, which is a protective layer that surrounds the brain and spinal cord. The support cells in the brain are called glial cells, which provide structural support and help maintain the health of the nerve fibers. Myelin is also present in the brain, produced by a type of glial cell called oligodendrocytes, to insulate and protect the nerve fibers.

In addition to these structures, the nerve fibers in the brain are also held together by a network of blood vessels and other supporting cells. This complex network helps to maintain the integrity and proper functioning of the brain.

I hope this helps answer your question. If you have any further inquiries about the brain, please feel free to ask. Thank you.
 

FAQ: Nerve fibres of brain (Quick question)

1. What are nerve fibers of the brain?

Nerve fibers of the brain, also known as axons, are long, thin projections of nerve cells that transmit electrical signals to other cells in the body. They are essential for communication between different parts of the brain and between the brain and the rest of the body.

2. How are nerve fibers of the brain classified?

Nerve fibers of the brain can be classified based on their size, myelination (presence of a fatty sheath), and function. They can be divided into two main types: myelinated and unmyelinated fibers. Myelinated fibers are covered in a fatty substance called myelin, which allows for faster transmission of signals. Unmyelinated fibers do not have this sheath and are slower in transmitting signals.

3. What is the importance of nerve fibers of the brain in controlling movement?

Nerve fibers of the brain play a crucial role in controlling movement. They transmit signals from the brain to the muscles, allowing us to perform voluntary movements. This communication between the brain and muscles is essential for coordinated movement and motor skills.

4. How do nerve fibers of the brain contribute to sensory perception?

Nerve fibers of the brain are responsible for transmitting sensory information from the body to the brain. They carry signals from sensory organs such as the eyes, ears, and skin to the brain, allowing us to perceive sensations such as sight, sound, and touch.

5. Can nerve fibers of the brain regenerate after injury?

Unlike other cells in the body, nerve fibers of the brain have limited ability to regenerate after injury. However, some research has shown that under certain conditions, nerve fibers may be able to regrow and reconnect with other nerve cells. This process, known as neuroplasticity, is being studied to develop treatments for brain injuries and diseases.
