These next two back (spine) muscles are deep and really hard to access!
Intertransversarii
Inter = between Tranversarii = refers to the transverse processes!
These little muscles live between the transverse processes (TVPS)* These are the deepest muscles in the cervical* and lumbar* spine. (they are not in the thoracic spine!)
* see "breaking down the spine" for a visual of : tranverse processes, spinous processes (SPs) cervical, thoracic & lumbar spine.
Muscle Attachments - Origin & Insertion:
Cervical Spine: spans the TVPs C2- C7
Lumbar Spine: spans TVPs of L1-L5
Muscle Actions:
Unilaterally (one side of spine only): laterally flexes the vertebral column to the same side
Bilaterally (both sides) : extends the vertebral column
Interspinalis:
Inter = between spinalis = referring to spinous processes !
Inter = between spinalis = referring to spinous processes !
these lil' muscles live between the spinous processes in the cervical and lumbar areas of the spine - Like the intertransversii above, these muscles are too deep to isolate!
Origin & Insertion:
Cervical: spanning SPs C2 -T3
Lumbar: spanning SPs of T12- L5
Muscle Action:
extends the spine !That's it for back muscles!
Hips & Legs are next :)
