Answer:
ExplanaA nerve is a cable-like structure within the body designed to conduct nerve impulses that relay information from one part of the body to another.
A typical nerve is made up of a bundle of fibres which are wrapped around layers of tissue and fat, and they stretch throughout the body. These nerves transmit information along the axons to the respective organs. These are the basic elements that constitute a nerve.
Nerves are a part of the nervous system. They are primarily involved in control and the coordination of all the parts of the body.
The nervous system not only sends and receives messages but also processes them into chemical signals called impulses in the human body. A wide network of nerves is spread throughout our body, which also runs through the brain, the spinal cord and many organs.
Nerves are the organs that make up the peripheral nervous system. It consists of a cord-like structure with multiple nerve fibres (also called axons) wrapped in layers of tissue and fat. This axon has layers of connective tissue around it. This connective tissue is called the endoneurium. This entire nerve is further enclosed in another layer of connective tissue called the epineurium.
The structure of a nerve is explained below:
A group of neurons is organized into bundles inside the nerves. This bundle is known as fascicles.
The perineurium surrounds and holds together each fascicle.
The perineurium is concentrically laminated and composed of flattened cells collagen fibres and basement membranes.
Neurons and blood vessels are held inside the fascicles by a loose connective tissue known as endoneurium. It covers and holds the outer surface of the nerves together.
Arteries and veins are present between the fascicles. These blood vessels supply nutrients and gases to the neurons inside the fascicles.
Types of Nerves
There are three types of nerves in the human body which are classified based on their functions. These are the sensory nerves, motor nerves and mixed nerves.
Sensory Nerves
These are the nerves that send messages to the brain or the spinal cord from the sense organs. These are enclosed in the form of a bundle like structures or nerve fibres in the peripheral nervous system. They carry information from the PNS to the CNS( Central Nervous System).
Motor Nerves
Motor nerves are those nerves those that carry the messages in the form of a response from the brain or the spinal cord to other parts of the body such as the muscles and glands. They are responsible for carrying the information from the CNS to the PNS.
Mixed Nerves
Mixed nerves are the nerves that perform both the action of sensory nerves as well as a motor nerve. They transform electrical impulses from the central nervous system to the muscles of the body. Generally, the mixed nerves transmit impulses at the rate of 120 metres per second or 432 kilometres per hour.
Function of Nerves
The primary function of nerves to conduct an electrochemical impulse and convey information. These impulses are carried by the individual neurons that make up the nerve.
These impulses travel from one neuron to another by crossing a synapse. The messages are converted from electrical to chemical and then back to electrical.
The sensory nerves carry information from the receptor to the central nervous system where the information gets processed.
The motor nerves, on the other hand, carry information from the central nervous system to the muscles.
Nerve Disorders
Nerve disorders include:
1.Pain
2.Muscle Malfunction
3.Changes in sensation
4.Changes in the senses
5.Vertigo
6.Dysarthria
7.Sleeping problems
8.Mental disability

Single-Select Questions with Reading Passage #1 Grocery Grabbr The following passage will be used to answer questions #1 - #5 Markus is finding that it takes too long to track down all of the groceries he needs to buy from a given store. Grocery Grabbr to the rescue! The app allows Markus to input his shopping list and search for his local grocery store in Grocery Grabbr's database. If his grocery store is there, Markus is all set to go! The database stores grocery items, cost, and item location information for each grocery store. When Markus walks into the store, a notification pops up on his smartphone letting him know that Grocery Grabbr is ready to get to work. Each of Markus' grocery items is displayed one at a time, along with the aisle number and shelf location. After Markus grabs his items off the shelf, he hits a button on the app to navigate to the next item. The list of items is arranged so that Markus follows the most efficient path through the grocery store. When Markus finishes shopping, the total amount of money his groceries cost is displayed, which allows him to double check the total cost with the cashier. Grocery Grabbr pays grocery stores a small amount of money for each user who successfully uses the app and checks out of the store with over one hundred dollars worth of groceries.
