In this article, I will explain the “caudal nerve” in detail.
The caudal nerve is a nerve bundle at the end of the spinal cord, and as the name suggests, it is shaped like a horse's tail. It plays an important role in motor nerves and sensory nerves in the lower body, and affects various physical functions. This article details the structure and function of the caudal nerve, related diseases and treatment methods, and provides basic information on the caudal nerve. Please use this article to deepen your understanding of the body.

What is the caudal nerve
The caudal nerve is a nerve bundle that extends from the end of the spinal cord, and its structure is similar to a horse's tail, hence the name. This nerve is one of the important nerves that control movement and sensation in the lower body, and if you use a human anatomy chart, you can understand its complex and delicate positional relationship in more detail.
How to read caudal nerve
The cauda equina nerve is read as “babi shinkei” in Japanese. This reading makes you intuitively imagine that its appearance resembles a horse's tail.
Characteristics of the caudal nerve
The most prominent characteristic of this nerve is its length and the fact that it is a bundle made up of multiple nerve fibers. Also, in terms of functionality, it plays an important role directly linked to daily life, by controlling movement, sensation, and even excretion function in the lower back.
Location/location of caudal nerve
If you look at the human anatomy diagram, you can see that the caudal nerve is located at the end of the spine, between the lumbar spine and the sacrum. In detail, lumbar vertebra 2 (L2) is the place where the caudal nerve begins.
How to remember the caudal nerve
An easy way to memorize the location of this nerve is to think of the phrase “nerve that continues from the waist to the tail.” Also, by studying while comparing it with a human anatomy diagram, you can understand positional relationships more deeply.
English and Latin for caudal nerve
In English, this nerve is expressed as “Cauda Equina.” It comes from Latin and literally means “horse tail.”
Trivia about caudal nerve
The caudal nerve is a general term for several different nerves, each extending to the lower body. Damage to this nerve can cause serious problems such as walking difficulties and excretion disorders, so it is very important for living a healthy lifestyle.
Tissues associated with the caudal nerve: characteristics of motor function
The caudal nerve is a nerve bundle that branches from the end of the spinal cord, and its main task is to transfer motor and sensory functions to the lower body. As a motor function, the caudal nerve sends movement commands to the lower leg muscles and supports basic movements such as walking, standing up, and sitting. It is also involved in fine movements, such as moving the toes, and fine adjustments for balance.
This motor function can be broadly divided into two nerve fibers. One is the motor nerve for large muscles, and the other is the fine nerve that controls small muscles and muscles located close to the surface of the skin. When these nerve fibers cooperate, our lower body can perform precise movements.
Tissues related to the caudal nerve: location and location of motor function
The cauda equina nerve extends from the bottom of the lumbar spine and branches through the buttocks to the lower legs. The main tissues innervated by this nerve span a wide range of areas, from the large muscle groups on the front and back of the thigh (quadriceps femoris and hamstrings), muscles that extend from the abdomen to the legs (iliopsoas), and even ankle and foot muscles. Motor nerve signals from the caudal nerve are essential for these muscle groups to function properly.
Tissues associated with the caudal nerve: trivia about motor function
The caudal nerve has several interesting features. For example, the act of a human standing up seems relatively simple, but in reality, many nerve signals are sent through the spinal cord to the caudal nerve, and it is necessary to activate the appropriate muscle groups. During this process, nerves coordinate muscle activity as if they were conductors.
Also, people who repeat specific movements, such as athletes and dancers, are particularly benefited by the cauda equina nerve and its motor function. Through repetitive training, the nervous system “learns” how to activate specific muscle groups more efficiently. This is one of the reasons for improved performance through practice.
Cauda equina quiz and correct answers
Q1.Which part of the spinal cord does the caudal nerve extend from?
Correct answer: It is between lumbar vertebra 5 and sacral spine 1.
summary
This time, I explained the location and location of the “caudal nerve”, how to memorize it, and the English/Latin notation.
How was it?
I would be happy if reading this article deepened my understanding of anatomy.
Learning is a long, never-ending journey, but I sincerely wish you all the best. Let's continue to study together and work hard for the national exam!
Please look forward to the next blog.
