What nerves cause cauda equina?
The cauda equina is the continuation of these nerve roots in the lumbar and sacral region. These nerves send and receive messages to and from the lower limbs and pelvic organs. Cauda equina syndrome (CES) occurs when there is dysfunction of multiple lumbar and sacral nerve roots of the cauda equina.What nerves are in the cauda equina?
A group of nerve roots that travel down from the spinal cord and the conus medullaris is called the cauda equina. The cauda equina contains nerve roots from L2 in the lumbar spine to Co1 in the coccygeal (tail bone end) spine.What is the most common cause of cauda equina syndrome?

Where do cauda equina come from?
[1] The cauda equina is a group of nerves and nerve roots stemming from the distal end of the spinal cord, typically levels L1-L5 and contains axons of nerves that give both motor and sensory innervation to the legs, bladder, anus, and perineum.Where are the cauda equina nerves located?
The cauda equina is the sack of nerve roots (nerves that leave the spinal cord between spaces in the bones of the spine to connect to other parts of the body) at the lower end of the spinal cord. These nerve roots provide the ability to move and feel sensation in the legs and the bladder.Cauda Equina Syndrome - Everything You Need To Know - Dr. Nabil
Is cauda equina upper motor neuron?

The principal causes of this syndrome are tumors, lumbar spinal stenosis, ruptured lumbar disc, arachnoiditis, and spinal fracture.What spinal nerve controls bowel bladder?
The cauda equina nerves supply muscle sensation to the bladder, bowel and legs. When these nerves become suppressed from Cauda Equina Syndrome then muscle sensation becomes lost which can result in loss of bladder and/ or bowel control.What are the symptoms of L3 nerve root compression?
When the L3 spinal nerve is involved, the following symptoms may occur:
- Sharp pain, typically felt as a shooting and/or burning feeling that may occur in the thigh and/or inner part of the leg. ...
- Numbness in the thigh and/or inner part of the leg. ...
- Weakness while moving the thigh and/or knee in different directions.
Can a bulging disc cause cauda equina?
A large ruptured disc can cause cauda equina syndrome. During a herniation, the gel-like center of a spinal disc can bulge or rupture through a weak area in the disc wall and compress the nerves. In the majority of cases, the disc herniation occurs at the L4-5 or L5-S1 discs in the lumbar spine.What are the symptoms of L5 S1 nerve damage?
Common Symptoms and Signs Stemming from L5-S1

This means you can't feel that you have to poop or pee, or you feel the sensation stronger than before.Is cauda equina peripheral or central nervous system?
The cauda equina is the conglomeration of the nerve roots of the lumbar and sacral spinal nerves distally to the conus area. These two areas form a transition between the central nervous system and the peripheral nervous system.What does saddle numbness feel like?
Numbness in or around the back passage and / or genitals; Inability to feel the toilet paper when wiping; Tingling sensation in the saddle area; Weakness in the saddle area.Can spinal stenosis cause cauda equina?

Numbness in different parts of the thigh, leg, foot, and/or toes.What nerves are affected by C4 C5 C6 and C7?
C5, as mentioned earlier, along with C3 and C4, contributes to the phrenic nerve that innervates the diaphragm. Roots C5, C6, and C7 produce the long thoracic nerve, responsible for controlling the serratus anterior.What nerves do C5 C6 affect?
A c5-c6 herniated disc can affect the nerves that control the muscles in the arms, neck, shoulders, hands as well as the head, eyes, ears, or thyroid gland. Symptoms in these areas in addition to pain in the neck is very common with c5-c6 disc herniations.What nerve causes bowel incontinence?

If those nerves become compressed or squashed, an individual may lose control of their bowel and sensation around the anus.How do you stimulate the sacral nerve?
To evaluate SNM as a therapy, a thin temporary wire is inserted near the sacral nerves in your lower back, [near your tailbone] which control the bladder/bowel. The wire is then connected to a small discrete external device which delivers stimulation to the nerves.What can mimics cauda equina syndrome?
Elsberg syndrome is a rare infectious syndrome that mimics cauda equina syndrome. 3 It is an acute, bilateral lumbosacral myeloradiculitis, which characteristically occurs secondary to herpes virus infection. Most commonly, HSV-2 is the causative pathogen, but VZV is also a well-recognised aetiological agent.Why are the roots of the lower spinal nerves referred to as the cauda equina?
