Explanation:
Answer: 31 pairs of spinal nerves
Explanation:
In the nervous system, bundles of fibres are called nerves.
The spinal nerve carries motor, sensory, and autonomic signals/information from the spinal cord to the brain and other part of the body.
The human body spinal cord consists of 4 regions, and 31 pairs of spinal nerves. The 31 pairs of spinal nerve are distributed one on each side of the vertebral column within the four regions of the spinal cord. The four regions of the spine are the cervical, thoracic, lumbar and sacral regions.
Answer is 31 pairs.
Some example sentences:
I did not want to walk to school today, for it was raining outside.
Fanboy-for, I did not want to walk to school today-Independent clause 1, it was raining outside-Independent clause 2
All of these sentences follow the same structure:
I want to adopt a dog, but they are a lot of work.
I wanted to stay separated from the group, so my teacher let me stay by myself.
We can go to the movies, or we can go to the amusement park.
I want to get ice cream, and I want to get coffee.
Pretty much any sentence like this will work.
Hope this helps :)

The two main components of the extracellular matrix are Elastin and Collagen.
The extracellular matrix is an intricate macromolecular network that is found in the extracellular space. The matrix is composed of polysaccharides and very diverse proteins, locally secreted and assembled forming a complex network that surrounds the cells. The matrix is highly developed in connective tissue and its derivatives. The extracellular matrix is formed mainly by proteins, glycosaminoglycans,proteoglycans and glycoproteins, organized in diverse networks that constitute the different tissues. <em>The most abundant proteins are collagen and elastin.</em>
Collagen is a family of very abundant proteins in the body of animals. Collagen molecules can represent 25 to 30 % of all body proteins. Its main mission in the tissues is to form a framework that supports the tissues and that resists the forces of mechanical tension.
The elastin molecules are very close to each other through links between the regions rich in the amino acid lysine. It is an abundant protein in may extracellular matrices and appears as a component of the so called elastic fibers, which are onsoluble aggregates of proteins.
