What is the difference between coccyx and coccygeal?
The coccygeal vertebrae, however, do not contain any pedicle, lamina or spinous processes. The coccyx serves as the site of attachment for multiple pelvic ligaments and tendons and contains an extensive plexus of coccygeal nerves.
What does coccygeal mean in anatomy?
Coccygeal: Referring to the coccyx, the small tail-like bone at the bottom of the spine, that is made up of 3-5 (average of 4) rudimentary vertebrae. There is a coccygeal nerve that originates in the spinal cord and emerges at the level of the coccyx.
What does the coccygeal bone do?
Despite its small size, the coccyx has several important functions. Along with being the insertion site for multiple muscles, ligaments, and tendons, it also serves as one leg of the tripod—along with the ischial tuberosities—that provides weight-bearing support to a person in the seated position.
Do humans have a coccygeal vertebrae?
At the very bottom of the human spine is a bone that sticks out a bit called the coccyx (cox-ix). We sometimes call it the “tailbone,” but it is actually made up of several different spinal bones.
How many coccygeal spinal nerves are there?
There are eight pairs of cervical nerves, twelve pairs of thoracic nerves, five pairs of lumbar nerves, five pairs of sacral nerves, and one pair of coccygeal nerves. The spinal nerves are part of the peripheral nervous system….

What can cause a painful coccyx?
Causes of tailbone (coccyx) pain
- pregnancy and childbirth.
- an injury or accident, such as a fall onto your coccyx.
- repeated or prolonged strain on the coccyx – for example, after sitting for a long time while driving or cycling.
- poor posture.
- being overweight or underweight.
Does coccyx pain go away?
Tailbone (coccyx) pain may improve after a few weeks, but it can sometimes last longer. There are some things you can do to help ease the pain.
Can coccyx pain be cured?
While there’s no instant cure for tailbone pain, some exercises and stretches can help relieve the pressure that causes tailbone pain.
What does the Coccygeal nerve control?
The S5 roots and coccygeal nerves leave the sacral canal via the sacral hiatus. These nerves provide sensory and motor innervation to their respective dermatomes and myotomes. They also provide partial innervation to several pelvic organs, including the uterus, fallopian tubes, bladder, and prostate.
What does the coccygeal nerve control?
Is pain in the coccyx serious?
You should call your doctor immediately if you have pain in the tailbone and any of the following other symptoms: A sudden increase in swelling or pain. Constipation that lasts a long time. Sudden numbness, weakness, or tingling in either or both legs.
How do you get rid of coccyx pain?
- Lean forward while sitting down.
- Sit on a doughnut-shaped pillow or wedge (V-shaped) cushion.
- Apply heat or ice to the affected area.
- Take over-the-counter pain relievers, such as acetaminophen (Tylenol, others), ibuprofen (Advil, Motrin IB, others) or aspirin.
What is the coccygeal vertebrae?
The last three to five (usually four) vertebrae of the spinal column are fused together to make the coccyx, colloquially known as the tailbone. 1 Fusion begins during a person’s 20s and is usually complete by the age of 30. Before fusion occurs, the coccygeal vertebra articulate just like any other section of the spinal column.
What is the anatomy of the coccygeal nerve?
The coccygeal nerves are the 31st pair of spinal nerves. They emerge from the conus medullaris, the termination of the spinal cord. The coccygeal nerve descends within the cauda equina along with the lumbar and sacral spinal nerves. The coccygeal nerve exits the sacral canal via the sacral hiatus and emerges inferior to the first coccygeal segment.
How many coccygeal vertebrae are in the sacrum?
There are usually four coccygeal vertebrae that attach to the apex (small, bottom part) of the sacrum. Most of the time, they are referred to as Co1-Co4. It is common and quite natural to be born with as few as three and as many as five coccygeal vertebrae.
What is the coccyx?
You are here. The coccyx is a triangular arrangement of bone that makes up the very bottom portion of the spine below the sacrum. It represents a vestigial tail, hence the common term tailbone.
