The gluteus maximus attaches to the coccyx, as does the levator ani muscle, which is a key component of the pelvic floor. The anococcygeal raphe is a thin, fibrous ligament which runs from the coccyx and helps support the position of the anus.

What ligaments are attached to the tailbone?
The anterior and posterior sacrococcygeal ligaments attach the sacrum to the coccyx (similar to the functions of the anterior and posterior longitudinal ligaments spanning cervical, thoracic, and lumbosacral spinal segments).
What muscle is near your tailbone?
The gluteus maximus attaches to the tailbone (coccyx) and may pull or become tightened when injured or aggravated.
Is your spine connected to your tailbone?
The bottom of the spine is called the sacrum. It is made up of several vertebral bodies usually fused together as one. The remaining small bones or ossicles below the sacrum are also fused together and called the tailbone or coccyx.
What is sacrococcygeal?
Sacrococcygeal teratomas are rare tumors that develop at the base of the spine by the tailbone (coccyx) known as the sacrococcygeal region. Although most of these tumors are non-cancerous (benign), they may grow quite large and once diagnosed, always require surgical removal.
What is Sacrococcygeal ligament?
Description. The posterior sacrococcygeal ligament consists a flat band, which arises from the margin of the lower orifice of the sacral canal, and descends to be inserted into the posterior surface of the coccyx.
Do any muscles attach to the tailbone?
Attachments. The anterior side of the coccyx has attachments to the levator ani muscle, coccygeus, iliococcygeus, and pubococcygeus, anococcygeal raphe. Attached to the posterior side is the gluteus maximus, which extends the thigh at the hip joint.
What muscles attach to sacrum?
Muscle attachments The iliacus and coccygeus also attach to the pelvic surface superolaterally and inferolaterally respectively. The erector spinae aponeurosis and multifidus cover the dorsal surface while the gluteus maximus attaches to the lateral borders of the sacrum.
Can you pull a muscle near tailbone?
If this motion is repeated many times, the muscles and ligaments around your coccyx can become strained and stretched. Straining your muscles and ligaments can permanently damage them. If this happens, your muscles will no longer be able to hold your coccyx in the correct position, causing pain and discomfort.
Why does my coccyx stick out?
Trauma or increased tension in the pelvic floor muscles can cause the coccyx to get stuck in one position. If the coccyx gets stuck out of alignment or in too much flexion or extension, the muscles that attach to it will have increased difficulty contracting when they need to.
Are coccyx and tailbone the same thing?
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.
What is spiral cord?
The spinal cord is a long bundle of nerves and cells that extends from the lower portion of the brain to the lower back. It carries signals between the brain and the rest of the body. This article covers the key anatomy of the spinal cord and its functions. It also provides some information about spinal cord injuries.
What causes teratomas?
What Causes Teratoma? Teratomas happen when complications arise during your cells’ differentiation process. In particular, they develop in your body’s germ cells, which are undifferentiated. This means they can turn into any type of cell – from egg and sperm to hair cells.
Is teratoma the same as pilonidal cyst?
A pilonidal cyst can resemble a dermoid cyst, a kind of teratoma (germ cell tumor). In particular, a pilonidal cyst in the gluteal cleft can resemble a sacrococcygeal teratoma.
What is an SCT tumor?
A sacrococcygeal teratoma / SCT is a tumor that develops in a baby in utero. It appears in the lower back and buttocks of a baby at the base of the tailbone (coccyx). Some tumors are diagnosed in utero, others at birth. Sacrococcygeal teratomas / SCTs are rare, occurring in about one in 35,000-40,000 births.
