What are the two main cells of the brain?
Generally, these would be the neurons and the supportive cells. Supportive cells, however, comprise several different kinds of cells. These include oligodendrocytes, glial cells, schwann cells, astrocytes, etc.
What is the outer most layer of bacterial and plant cells?
cell wall
What are nerve axon tracks made of?
The axons of nerve cells are surrounded by myelin sheeths - a protective covering that allows for saltatory conduction down the axons, increasing speed and decreasing loss of signal. Axons make up the tissue known as "white matter."
What is a tough rigid outer covering that protects the cell?
The rigid outer covering a plant cell is known as the cell wall. The cell wall is composed mainly of cellulose.
What is the covering of a wire made of?
plastic , rubber

What are brains made of?
The primary cell in the brain is the neuron. There are also many supporting cells, such as astrocytes, glial cells and the like.
What is the outer most layer of bacterial and plant cells?
cell wall
What is gray matter made out of?
Neuronal cell bodies, neuropil (dendrites and both unmyelinated axons and myelinated axons), glial cells (astroglia and oligodendrocytes) and capillaries.
What is the outer covering of fungal cells?
The outer covering of a fungal cell is called a cell wall and made of chitin and glucans.
What are nerve axon tracks made of?
The axons of nerve cells are surrounded by myelin sheeths - a protective covering that allows for saltatory conduction down the axons, increasing speed and decreasing loss of signal. Axons make up the tissue known as "white matter."
Is a shell a dead animal?
A sea shell may contain a dead animal but the shell itself is a protective covering that an animal made to protect itself.
What were the weaknesses in planes in World War 1?
What they were made from, lack of protective covering, engine failures, wing failures, burning up when your craft was shot down.
Rigid outer covering of plant cell?
This is known as the cell wall. It is not present on the cells of animals.
Does mollusks protect themselves?
Most of Mollusks protect themselves with help of shell . Shell is hard protective covering made up of CaCO3. Cephalopods are not protected by shell .
What is the structure of an animal cell membrane?
Cell membrane is the outermost covering in animal cells. in plant cells, it is the second outermost covering (the first one beinf the cella wall).
Is it possible for damaged neurons to regenerate?
When a neuron is damaged, the glial cells remove the neuron, and work to protect the other neurons.Glial progenitor cells can form into neurons or glial cells, depending on what type was damaged. http://www.brainandspinalcord.org/blog/2008/07/new-research-linking-cholesterol-drugs-and-brain-cell-repair/
