The five pairs of lumbar spinal nerves are L1, L2, L3, L4, and L5. These nerves emerge from the lumbar region of the spinal cord and are part of the larger group of spinal nerves that branch out to innervate various body regions. Each pair corresponds to a specific vertebral segment in the lower back.

How many pairs of dorsal nerves are there?
There are 12 pairs of Dorsal nerves also know as thoracic nerves. They emerge from the thoracic vertebrae hence the name.
What is the medical name for Spinal-cord injury?
The medical name for a spinal cord injury is Quadriplegia or Tetraplegia if the cord is damaged in the cervical (neck) region. If the spinal cord is damaged in the Thoracic area or lower, then the paralysis is refered to as Paraplegia. Also, injuries to the Lumbar and Sacral nerves which result in paralysis, are refered to as Cauda Equina Syndrome.
Where does the spinal cord start and ends?
In an adult the lower end of the spinal cord usually ends at approximately the first lumbar vertebra, where it divides into many individual nerve roots (L1). That is the reason Lumbar Puncture usually perform at L3-L4 in order to prevent accidentally injure to the spinal cord. The point where the spinal cord ends is referred to as the "conus medullaris"
What are the 31 spinal nerves called?
The proper name is Mixed Spinal Nerve.They do not have individual names, however. They are referred to by their number, with number one just above the first rib and the 31st going through the foramen between sacral 4 & 5.
What name is given to the channel of nerves that travel down the spinal cord?

What are name of the nerves that found in the nervous system?
There are different types of nerves in the human body namely: the cranial nerves, the spinal nerves, the sympathetic nerves, and the encephalon nerves just but to mention a few. Examples of these nerves includes: the optic nerve, the facial nerve, the vagus nerve, the thoracic nerve, and accessory nerve.
Why an epidural is likely to exert effects on nerves with slower and prolonged action than a spinal tap?
Essentially, when a spinal tap is given, a needle is inserted into the spinal canal in the lumbar area, medicine (or an anesthetic) is inserted directly into the cerebrospinal fluid (CSF). Numbness is usually immediate. However, in an epidural, a hollow needle and a catheder are inserted into space between the spinal column and the outer membrane of the spinal cord (EPIDURAL space). Hence the name "epidural".
What is another name for motor nerves, and how do they differ from sensory nerves in the nervous system?
Motor nerves are also known as efferent nerves. They differ from sensory nerves in the nervous system by carrying signals from the brain and spinal cord to muscles and glands, controlling movement and bodily functions. Sensory nerves, on the other hand, transmit signals from sensory organs to the brain and spinal cord, allowing us to perceive and respond to our environment.
What name refers to nerves that only originate in the brain carry messages to and from structures in the head and neck and are considered part of the peripheral nervous sytem?
These are 12 pairs of nerves called the cranial nerves.
Name the 2 subdivisions of the dorsal cavity what structures does each contain?
cranial which contains the brain and spinal which contains the nerves of the spinal cord.
What is the common name for Lumbar Spine?
lumbar vertebrae
How are cranial nerves named and numbered?
Cranial nerves are named based on their function or the region they innervate. They are also numbered based on their location from anterior to posterior as they emerge from the brain. There are 12 pairs of cranial nerves, each with a unique name and number.
