Anatomy Muscles of Back
What muscle inserts itself at the transverse processes between the tubercles and angles of ribs, transverse processes of thoracic and cervical vertebrae, and mastoid process?
Longissimus
What muscle originates at the Transverse processes posterior to the sacrum, iliac crest, sacropinous ligament and spinous processes of the lower lumbar and sacral vertebrae?
Longissimus Muscle Group
Which muscle functions to retract the scapula, rotate inferiorly to depress the glenoid cavity and hold the scapula close to the posterior thoracic wall?
Rhomboid Muscles (Major and Minor)
This muscle is oriented obliquely between nuchal ligament/spinous process C7-T5 and medial border of the scapula? Which is larger?
Rhomboid muscles -Rhomboid Major is larger but lies inferiorly to Rhomboid Minor
What muscle has the function for most rotary action: smallest and cannot provide much muscular force. Also used for proprioception?
Rotatores
What muscles insert at the lamina and transverse process of spine above (spanning two segments)?
Rotatores
What muscles originate at the transverse processes of cervical, thoracic and lumbar regions?
Rotatores
Which muscles make up the Transversospinalis Muscles?
Semispinalis Capitis, Semispinalis Cervicis, Multifidis Lumborum, Rotatores
What muscle originates at the transverse processes of lower cervical to lower thoracic region?
Semispinalis Capitis/Cervicis
What muscles function for extension of neck and skull?
Semispinalis Capitis/Cervicis
What muscle inserts at the spinous process of cervical and thoracic regions?
Semispinalis Capitis?Cervicis
Which muscle is located at the spinous processes of T11-LS to inferior borders of 8-12th ribs?
Serratus Posterior Inferior
Which muscle originates at the nuchal ligament and spinous process of C7-T3 attaching to the superior borders of 2-4th ribs
Serratus Posterior Superior
What muscle functions as the muscle of respiration and proprioception?
Serratus Posterior Superior and Inferior
Blood supply of the Trapezius muscle
superficial cervical
What is the embryonic orgin of the Splenius Capitis and Splenius Cervicis?
Epaxial Myotomes
What is the embryonic origin of the trapezius?
Hypaxial myotomes
What muscle inserts at the ribs or transverse processes above angles of lower ribs and cervical transverse processes?
Iliocostalis Muscle Group
What muscle originates at the ilium and ribs, posterior sacrum, iliac crest, sacrospinous ligament and spinous processes of lower lumbar and sacral vertebrae?
Iliocostalis Muscle Group
What muscles make up the Erector Spinae Muscles?
Iliocostalis, Longissimus, Spinalis
Which muscle function is to pull the shoulder into adduction and slightly into extension?
Latissimus Dorsi
Which muscle originates at the iliac crest, thoracolumbar fascia, lumbar spinous processes?
Latissimus Dorsi
What muscle functions to elevate and rotate the scapula to transverse processes of C1-C4?
Levator Scapulae
Which muscle originates at the superior angle of the scapula attaching to the transverse processes of C1-C4?
Levator Scapulae
What muscle functions as the major extensor and posterior stabilizer of lumbar vertebrae. Acts with longissimus muscles that oringinate in lumbar spine. Minor rotary role in lumbar region?
Multifidis Lumborum
What muscle inserts at the spinous processes of vertebrae above (spanning two to four segments)?
Multifidis Lumborum
What muscle originates at the sacrum, ilium and transverse processes of thoracic region and articular processes of lower cervical region?
Multifidis Lumborum
What muscle inserts to the spinous processes of the upper thoracic and midcervical vertebrae?
Spinalis Muscle Group
What muscle originates at the spinous processes posterior sacrum, iliac crest, sacrospinous ligament and spinous processes of lower lumbar and sacral vertebrae?
Spinalis Muscle Group
What muscle functions of bilateral contraction pulling the trunk into extension or holding the trunk stable at any degree of flexion. Unilateral contraction would function to side-bend the torso to ipsilateral side?
Spinalis Muscle Group, Longissimus, Iliocostalis
What muscle has the function of unilateral contraction, turning the head to ipsilateral side and elevate slightly. Bilateral contraction extending the neck and head?
Splenius Capitis Cervicis
What muscle is located obliquely between the spine and skull and neck?
Splenius Capitis/Cervicis
Which muscle has the function of moving and controlling the scapula?
Trapezius
Which muscle inserts it's self at the spine and acromion of the scapula
Trapezius
Which muscle originates at the spinous processes of cervical and thoracic vertebra; occipital region of the skull?
Trapezius
