Anatomy Muscles Of The Back

Front 1

What is the innervation of the trapezius muscle

Back 1

accessory nerve (Cr. 11)

Front 2

attachments of the Trapezius

Back 2

Skull, spinal column, spine of scapula

Front 3

actions of the trapezius

Back 3

elevation of the scapula, rotation of lateral aspect of scapula upward

Front 4

vascularization of the trapezius

Back 4

superficial branch of the transverse cervical artery, acromial branch of suprascapular artery and dorsal branches of posterior intercostal arteries

Front 5

Latissimus dorsi attachments and action

Back 5

lower spinal column, the humerus: extension, adduction and medial rotation of the upper limb

Front 6

Latissimus dorsi, innervation

Back 6

thoracodorsal nerve of brachial plexus:

Front 7

Latissimus dorsi, blood supply

Back 7

thoracodorsal artery

Front 8

Rhomboid major and minor, blood supply

Back 8

deep branch of transverse cervical artery

Front 9

Rhomboid major, attachments and action

Back 9

spinous process of upper thoracic vertebrae to medial scapular border: pulls the scapula toward the vertebral column

Front 10

Rhomboid minor, attachments and action

Back 10

spinous processes of CVII and TI to medial scapular border: pull scapula toward vertebral column

Front 11

Rhomboid major and minor, innervation

Back 11

dorsal scapular nerve (of the brachial plexus)

Front 12

Levator scapulae, attachment and action

Back 12

transverse processes of CI to CIV to upper part of the medial border of scapula, retracts and elevates scapula

Front 13

Levator scapulae, innervation and blood supply

Back 13

Dorsal scapular nerve(C3 andC4)

branches of the transverse and ascending cervical arteries

Front 14

Erector spinae attachments and actions

Back 14

Run from spinous processes medially to the ribs laterally and superiorly; Extensors of spinal column and head

Front 15

Erector spinae, innervation and blood supply

Back 15

segmentally innervated by dorsal primary rami of spinal nerves C1-S5 supplied segmentally by: deep cervical a., posterior intercostal a., subcostal a., lumbar a

Front 16

Transversospinalis, attachments and actions

Back 16

run obliquely upward and medially from transverse processes to spinous processes; extend the vertebral column, unilaterally they rotate the trunk

Front 17

Transversospinalis, innervation

Back 17

Innervated by dorsal rami of spinal nerves

Front 18

Transversospinalis, blood supply

Back 18

superficial branch of transverse cervical artery
