The functional and structural unit of nervous system is neuron.A collection of 1000s of neurons tightened together is called a nerve.

∙ 12y agoA nerve consists of many nerve fibers, which are long, slender projections that transmit electrical impulses throughout the body. These nerve fibers are bundled together with connective tissue to form a nerve, which can vary in size and function depending on its location and purpose in the body. Each nerve is responsible for carrying sensory information to the brain or spinal cord, and for transmitting motor signals from the brain or spinal cord to muscles and glands.

A dermatome consists of an area of skin innervated by sensory fibers from a single spinal nerve. These nerves transmit sensation, such as touch, temperature, and pain, from specific regions of the skin to the brain. Mapping dermatomes helps in diagnosing nerve injuries and localizing the source of symptoms related to nerve compression or damage.
The ventral root of a spinal nerve contains only efferent fibers, which carry motor signals from the central nervous system to the muscles and glands in the body.
No, a nerve is not a complete cell. Nerves are made up of nerve cells called neurons that consist of a cell body, dendrites, and an axon. The nerve cell works together with other cells to transmit signals throughout the body.
Nerve cells are elongated, not circular, in shape. This elongated shape allows nerve cells to efficiently transmit electrical signals over long distances. The elongated structure of nerve cells helps in their function of communication and transmission of signals throughout the body.
The simplest nervous systems are called nerve nets. They are found in organisms like jellyfish and sea anemones and consist of interconnected neurons spread throughout the organism's body without a centralized brain or ganglia.

Treatment can consist of the use of nonsteroidal anti-inflammatory drugs to control swelling around the nerve. The use of splints or cushions can ease the discomfort and the stress on the ulnar nerve.

Preganglionic because they are myelinated. FALSE
Nothing is faster than light. Your thoughts consist of tiny electric currents flowing through nerve cells from one part of your brain to another.
Anesthesia dolorosa results when the trigeminal nerve is damaged by surgery or physical trauma. The complications can consist of loss of feeling sensation in parts of the face while it continues to have lingering pain.
Chordates are not vertebrates because although some vertebrates are chordates theres many reasons why chordates arent vertebrates.the first reason is because chordates consist of a notochord or a dorsal nerve.
A nerve net is a type of simple nervous system that is found in members of the cnidaria and echinodermata phyla . Nerve nets consist of interconnected neurons lacking a brain or any form of cephalization. This nervous system allows cnidarian to respond to physical contact. They may then detect food and other chemicals in a rudimentary way. Although the nerve net allows the animal to respond to its environment, it has trouble alerting the animal from where the is coming. For this reason, simple animals with nerve nets, such as haunda, will typically respond in the same way to contact with an object, regardless of where the contact occurs. Hydra, which are cnidarians, have a nerve net throughout their body. On the other hand, , which are echinoderms, have a nerve net in each arm, connected by a central radial nerve ring at the center. This is better suited to controlling more sex movements than a diffuse nerve net .
