A neurolemma is the outer membrane of a Schwann cell or nerve cell that plays a crucial role in the regeneration of damaged peripheral nerves. It provides structural support and guidance for regenerating axons, helping them reconnect and restore function after injury.
At rest, the nerve membrane is referred to as polarized, meaning there is a difference in electrical charge between the inside and outside of the cell. This difference is maintained by the sodium-potassium pump, which actively transports ions across the cell membrane.
Neurolemma is just an outer shell of the myelin sheath, it's function is to protect a myelinated cell from injury and aid in its healing from injury by allowing information to travel faster to the brain that an unmyelinated cell.

The sense of sight is considered to be the most important sense for human beings.
because it is important! (well, how r we supposed to know why it is important!) don't u know it yourself? well, its important so that we can know how hot or cold a body is........... =P
No. Neurons have a cover on a part called the axon. This is called a neurolemma. Not all axons have this covering. This cover acts like the cover on an electrical cord. It prevents it from short circuiting and increases the speed which the impulse travels.
The neurolemma is more permeable to potassium than sodium during the resting state of a neuron, known as the resting membrane potential. This is due to the presence of leak potassium channels that allow potassium ions to move more freely across the neurolemma, contributing to the negative charge inside the neuron.
Neurolemma, also known as the Schwann cell sheath, is the outermost layer of the myelin sheath surrounding peripheral nerve fibers. Its primary function is to facilitate the regeneration of damaged nerve fibers by providing a supportive environment and guiding the growth of new axonal connections. Additionally, neurolemma plays a role in maintaining the health and integrity of peripheral nerves by insulating and protecting the axons.
It provides insulation to the axons and dendrites during depolarization or action potential.

The gap between each myelinated section of an axon is known the node of ranvier.
It is the outer layer of protection of the Cell. It controls what goes in and out of the Cell. It contains lipids, proteins, and phospholipids. It is very important because it protects the Cell from the environment.It is called a neurolemma if it is around a nerve cell, and a sarcolemma if it is around a muscle cell.cell mem·branenounthe semipermeable membrane surrounding the cytoplasm of a cell.hope this helps!
The part of the peripheral nerve tissue that helps promote regeneration of neurons is the neurolemma. It refers to the thin sheath around a neural axon.

The potassium (K+) channel gate opens immediately after an action potential has peaked. This allows potassium ions to flow out of the cell, resulting in repolarization of the membrane potential back to its resting state.
The nervous system is composed of several basic cell types, including nerve cells called neurons, interstitial cells called neurolemma (cells of Schwann), satellite cells, oligodendroglia, and astroglia; and several connective-tissue cell types, including fibroblasts and microglia, blood vessels, and extracellular fluids.
