1

interspinalis is paired in which regions of the spine

cervical and lumbar

2

location interspinalis will be absent along the spine

T3-T4 down to T10-T11

3

based on the density of muscle spindles what is the proposed function of the interspinalis

acts as a proprioceptive transducer in conjunction with intertransversarii to coordinate the smooth movement of the spine and to maintain appropriate posture

4

which of the cervical intertransversarii is innervated by dorsal rami of cervical spinal nerves

posterior medial belly, cervical intertransversarii

5

origin of the medial belly of the lumbar intertransversarii

accessory process of transverse process L1-4
mammillary process of superior articular process L1-4

6

lumbar intertranvsersarii that is innervated by both dorsal rami of lumbar spinal nerves

medial belly, lumbar interstransversarii

7

muscle group is innervated by both dorsal rami and ventral rami of spinal nerves

interstranversarii

8

based on the density of muscle spindles what is the proposed function of the intertransversarii

proprioceptive transducer in conjunction with interspinalis to coordinate smooth movement of the spine and to maintain appropriate posture
