|
Trapezius
|
-Location: Superficial Back
-Function: Elevated, rotates and retracts scapula -Innervation: Spinal Accessory Nerve |
|
Latissimus Dorsi
(arises from thoracolumbar fascia) |
-Location: Superficial Back
-Function: Extends, adducts (toward medial plane), and medially rotates the humerus -Innervation: Thoracodorsal nerve |
|
Thoracolumbar fascia
|
-Location: Superficial back, inferior to the L. dorsi
|
|
Rhomboid Major
|
-Location: Superficial Back, deep to the trapezius (inferior to rhomboid minor)
-Function: Retracts scapula and rotates it to depress glenoid cavity -Innervation: Dorsal scapular nerve |
|
Rhomboid Minor
|
-Location: Superficial bak, deep to the trapezius
-Function: Retracts scapula and rotates it to depress glenoid cavity -Innervation: Dorsal scapular nerve |
|
Levator Scapulae
|
-Location: Superficial Back, superior to trapezius (by neck)
-Function: elevates scapula and tilts its glenoid cavity inferiorly -Innervation: Dorsal scapular nerve |
|
Serratus Posterior Superior
|
Location: Intermediate back, deep to the rhomboids
Function: Respiration |
|
Serratus Posterior Inferior
|
Location: Intermediate back, deep to latissimus dorsi
Function: Inspiration |
|
Splenius capitis and cervicis
|
-Location: Intrinsic back(***innervated by dorsal primary rami)
-Function: ~Together: extend head and neck ~Alone: laterally flex neck an rotate head to side of active muscles - Innervation: Posterior rami of spinal nerves (dorsal primary rami) |
|
Ligamentum nuchae
|
-Location: Intrinsic back
-Function: Connects |
|
Semispinalis capitis
|
-Location: Intrinsic back
-Function: Extends head and thoracic and cervical regions of vertebral columns, and rotates them contralaterally (medially) -Innervation: Posterior rami of spinal nerves (dorsal primary rami) |
