What muscles connect T12?
The large back muscles the latissimus dorsi and trapezius have attachments on T12. The diaphragm, while not attaching at either of these spots lives in the neighborhood.

What is Multifidi?
Multifidus muscle (musculi multifidi) Multifidus is a group of short, triangular muscles that along with the semispinalis and rotatores comprises the transversospinal group of deep back muscles. They are the thickest muscles in the transversospinal group, and are shorter than semispinalis, but longer than rotatores.
What is the function of the longissimus?
The erector spinae muscles, including longissimus, are the most powerful extensors of the vertebral column. Hence their main actions include spine extension and lateral flexion. Longissimus capitis also rotates the head.
Can a T12 fracture cause paralysis?

- Bed rest for a short time, followed by limited activity while your bones heal.
- Wearing a back brace.
- Physical therapy to help you move better and strengthen the muscles around your spine.
Is T12 L1 considered thoracic or lumbar?
Currently, T12-L1 is considered a thoracic level for both transforaminal and facet injections. For transforaminal approach at T12-L1, this is considered thru the T12 foramen where the T12 spinal nerve exits. For facet joint blocks, the T12-L1 facet joint receives innervation from the T11 and T12 medial branches.
What does T12 mean?
Trailing Twelve Months (TTM) In the world of finance, the abbreviation TTM tends to come up a lot. TTM, or sometimes T12, stands for “trailing twelve months” and often refers to a financial statement that represents the entity’s performance over the past year.

Why shingles affect Dermatomes?
This is because each nerve runs from one side of the spine in the back to the middle of the front of the body and does not cross this midline. This is important when considering the rash of shingles.

What do Dermatomes tell you?
Dermatomes are important because they can help to assess and diagnose a variety of conditions. For instance, symptoms that occur along a specific dermatome may indicate a problem with a specific nerve root in the spine.
What is the cauda?
Cauda is Latin for tail, and equina is Latin for horse (ie, the “horse’s tail”). The CE provides sensory innervation to the saddle area, motor innervation to the sphincters, and parasympathetic innervation to the bladder and lower bowel (ie, from the left splenic flexure to the rectum).

What kind of muscle is the longissimus thoracis?
The longissimus thoracis muscle is the largest of the erector spinae muscles. It arises from the common origin of the erector spinae muscles (see Iliocostalis Lumborum). In addition, many fibers begin from the transverse and accessory processes of the lumbar vertebrae (see Chapter 7).
What is the longissimus capitis muscle?
Longissimus capitis is the part of the longest muscle of the neck, which serves to rotate the head from side to side and extend the head.

The rotatores muscles function to move the spine and back in several different directions, including a forward bend.
What Innervates Interspinales?
The interspinales muscles are innervated by the medial branches of the posterior primary divisions of spinal nerves. The interspinales muscles function to extend the spine and may act as proprioceptive organs (Bogduk, 2005).
What is Flavum?
One of a series of bands of elastic tissue that runs between the lamina from the axis to the sacrum, the ligamentum flavum connects the laminae and fuses with the facet joint capsules. … As we age, the ligament loses elastin, and this allows the ligament to encroach on the canal.
