Question 1

Which suboccipital muscle lacks attachment to the skull?

Answer 1

obliquus capitis inferior

Question 2

An increase in the density of the muscle spindles is most apparent in which suboccipital muscle?

Answer 2

obliquus capitis inferior

Question 3

What is the result of the communication between suboccipital muscles, visual centers, and vestibular centers?

Answer 3

coordination of head and eye position

Question 4

What is proposed function of the suboccipital muscle group?

Answer 4

postural stabilizers off the atlanto-occipital and atlanto-axial joints

Question 5

Which suboccipital muscles are knownto attach to the dura mater?

Answer 5

rectus capitis posterior major, rectus capitis posterior minor, and obliquus capitis inferior

Question 6

At what locations will interspinalis be absent along the spine?

Answer 6

T3-T4 down to T10-T11

Question 7

Based on the density of muscle spindles what is the proposed function of the interspinalis?

Answer 7

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

Question 8

Which muscle group is innervated by both dorsal rami and vantral rami of spinal nerves?

Answer 8

intertransversarii

Question 9

Based on the density of muscle spindles what is the proposed function of the intertransversarii?

Answer 9

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