anterior and lateral deep cervical musculature Flashcards
What is the origin of the longus colli?
vertebral bodies of C5-C7, T1-T3 and anterior tubercles of transverse processes C3-C5
What is the insertion of the longus colli?
anterior tubercle of the anterior arch C1, vertebral bodies of C2-4, and anterior tubercles of transverse processes C5-6
What will innervate the longus colli?
ventral rami of C2-6 or C7 spinal nerves
What is the origin of the longus capitis?
anterior tubercles of transverse processes C3-6
What is the insertion of the longus capitis?
basilar part of the occipital bone
What will innervate the longus capitis?
the ventral rami of C1-3 spinal nerves
What is the origin of the rectus capitis anterior?
lateral mass and costal element of the transverse process of C1
What is the insertion of the rectus capitis anterior?
basilar part of the occipital bone
What will innervate the rectus capitis anterior?
ventral rami of C1-C2 spinal nerves
What is the origin of the rectus capitis lateralis?
costal element of the transverse process of C1
Contraction of rectus capitis lateralis will result in what movements?
laterally flex the head to the ipsilateral side
What will innervate the rectus capitis lateralis?
the ventral rami of C1-2 spinal nerves
What is the origin of the anterior scalene?
anterior tubercles of transverse processes C3-6
What is the insertion of the anterior scalene?
ridge and anterior scalene tubercle of the first rib
What will innervate the anterior scalene?
the ventral rami of C2-6 spinal nerves
What is the origin of the middle scalene?
transverse process of C1, C2 and posterior tubercles of transverse processes C3-C7
What is the insertion of the middle scalene?
between the tubercle and groove for the subclavian artery on the first rib
What will innervate the middle scalene?
the ventral rami of C3-C8 spinal nerves
What is the insertion of the rectus capitis lateralis?
jugular process of the occipital bone
Contraction of anterior scalene will result in what movements?
flexion and lateral flexion (bending) of the neck and rotation of cervicals to the contralateral side; elevates first rib
Contraction of middle scalene will result in what movements?
laterally flex the neck; elevate the first rib
What is the insertion of the posterior scalene?
outer surface of second rib
Contraction of posterior scalene will result in what movements?
laterally flex the neck; elevates the second rib
What will innervate the posterior scalene?
the ventral rami of C6-C8 spinal nerves
