What is the name of the dense fibrous covering around the bound?
The dense fibrous covering around bones is called the periosteum. It contains blood vessels, nerves, and cells involved in bone growth and repair.
What is the reason that plant cells have an extra thick outer covering andwhatis the outer covering called?
Plant cells have an extra thick outer covering called a cell wall, which provides structural support to the cell and protects it from mechanical damage. The cell wall is made up of cellulose fibers, which give it strength and rigidity.
Why does nerves fatigue?
Usually nerves have good capacity to send signals. These signals are send by depolarization waves across the nerve fibers. For re polarization of the nerves, energy is required and if impulses has to be sent more repeatedly than energy can be generated by cells, there will nerve fatigue, for example after an attack of Fit.(Seizer attack.)
What are long fibers called?
Muscle cells are called fibers.
Do nerves contain cells?
Yes, we have nerve cells.
What is the covering of nerve fibers made up of living cells?
what is the portion of the brain containing control certer for body's functions and emotions: means "under the inner rool"
How are nerves formed?
Nerves are formed in a late stage of development, when some of the cells composing the nerve cord and the brain send out long fibers bound together in bundles (nerves).
What are hair nerves?
Hair is dead cells and actually has no nerves. When you pull on your hair, it is actually the living nerves in your scalp which register it.
What are nerves composed of?
Nerves are composed of nerve cells; the long connecting parts of the nerve cells are called axons. The biochemistry of nerve cells is similar to that of other cells, but they do have an insulating layer, the myelin sheath, which gives them a relatively high concentration of fat.
At what junction do nerves contact skeletal muscle fibers?
Motor neurons meet the muscle cells at neuromuscular junctions. Neurotransmitters are passed from the nerve across a synaptic cleft to the muscle to make it contract. Any damage to this nerve will mean that those cells will not contract (move).
How does the schwann cell repair damaged nerves?
Schwann cells play a crucial role in repairing damaged nerves by forming a tube-like structure that guides the regrowth of nerve fibers. They also produce growth factors and provide structural support for the regenerating nerve fibers. Additionally, Schwann cells help to remyelinate the nerve fibers, restoring their ability to conduct electrical impulses.

The dense fibrous covering around bones is called the periosteum. It contains blood vessels, nerves, and cells involved in bone growth and repair.
What is the function of of periosteum?
AnswerThe Periosteum serves as an attachment point for muscles and bones through tendons and ligaments. -----------------------------------------------------------------------------------------------------------Or, Inner layer can breakdown and build bone cells. Not necessarily its "function". It's a fibrous membrane covering (of bone), attached by fibers that happen to enter into bone, "Sharpey's fibers"; allowing nerves, and blood / lymphatic vessels to pass though it and then into bone through nutrient foramina. The periosteum covers bone and provides nourishment to the bone through the blood vessels and nerves contained within it.
What protects nerves?
the blood
A thin covering that the cells in all living things have?
Cell membrane, also known as the plasma membrane, is a thin covering that surrounds the cells of all living organisms. It regulates the passage of substances in and out of the cell, maintaining cellular homeostasis and providing structural support.
What are perineural cells?
Perineural cells are formed from the perineurium, which is the middle layer of the protective perineural sheath. These cells isolate bundles of axons from connective tissues and form a diffusion barrier
