WHAT ARE THE INTERSPINALIS CERVICIS?
-deeper spinal muscles; from C2-T1
-PAIRED MUSCLES run vertical up either side of
INTERSPINOUS LIGAMENT (on SPs)
-starts of as RECTUS CAPITIS MAJOR and MINOR
b/w occiput, C1 and C2
WHAT ARE INTERTRANSVERSARIUS CERVICIS?
- deeper spinal muscles often absent b/w C1/C2
- PAIRED MUSCLES run vertical up each SIDE of C/S
- attached to the TRANSVERSE PROCESSES’
- ANT. INTERTRANSVERSARII attachment ant. tubercle
- POST. INTERTRANSVERSARII “ posterior tubercle
