Upper Limb Attachment Points Flashcards
Multifidus
Lamina of all vertebrae of the TP or articular processes of all vertebrae inferior, from C2 to sacrum but most prominent in the lumbar region
Bilaterally: Extends spine
Unilaterally: Rotates the spine contralaterally (multifidus also side bends the body ipsilaterally)
Rotatores (Longus & Brevis)
Lamina and SP of the thoracic vertebrae to the TPs of 1 or 2 segments inferiorly
Bilaterally: Extends spine
Unilaterally: Rotates the spine contralaterally (multifidus also side bends the body ipsilaterally)
Interspinales
Between SPs of adjacent vertebrae in all spinal regions more prominent in the lumbar and cervical regions
Extends the spine
Intertransverarii
Between TPs of adjacent vertebrae in all spinal regions, more prominent in the lumbar (medial and lateral) and cervical (anterior and posterior)
Bilaterally: Stabilize and extends cervical and lumbar spine
Unilaterally: Side bends the spine ipsilateral
Iliocostalis (Lumborum, Thoracis, Cervicis)
Sacrum, thoracolumbar fascia, and iliac crest to the angles of all ribs and TPs of C4-C7
Bilateral: extends spine (and head)
Unilateral: Side bends spine ipsilaterally and head
Longissimus (Thoracis, Cervicis, Capitis)
Sacrum, thoracolumbar fascia, SPs of lumbar vertebrae, TPs of thoracic vertebrae, TPs of thoracic vertebrae, articular pillars of C4-C7 vertebrae to the TPs of the lumbar vertebrae, 2-12 ribs between the tubercles and angles, the TPs of cervical vertebrae, mastoid process of the occiput
Bilateral: extends spine (and head)
Unilateral: Side bends spine ipsilaterally and head
Spinalis (Thoracis & Cervicis)
SPs of: T10-L3, T1-T2, C5-C7 to the SPs of T2-T8 and C2-C5, spanning all vertebrae on the lateral aspect
Bilaterally: Extends spine (and head)
Unilateral: Side bends spine ipsilaterally (and head)
Quadratus Lumborum
TP of lumbar vertebrae and 12th rib to the iliac crest
Bilaterally: Extends spine; pulls 12th rib inferiorly
Unilaterally: Side bends spine
External Obliques
External surfaces, ribs 5-12, linea alba, rectus sheath, pubic tubercle and iliac crest
Compresses and supports abdomen and viscera; flex trunk
Rectus Abdominis
Costal cartilages 5-7 and xiphoid process to the pubic tubercle
Compresses and supports abdomen and viscera; flex trunk
Internal Obliques
Thoracolumbar fascia, iliac crest and inguinal ligament to ribs 10-12, linea alba, rectus sheath and pubic tubercle
Compresses and supports abdomen and viscera; flex trunk
Transverse Abdominis
Thoracolumbar fascia, iliac crest, ribs 7-12, ASIS and the inguinal ligament to the linea alba
Compress and support abdomen and viscera, flex trunk
Pectoralis Major
Sternal end of the clavicle and the sternocostal joints of ribs 1-7 to the greater trochanter of the humerus
Adducts, flexes and medially rotates humerus
Pectoralis Minor
Coracoid process to ribs 3-5
Stabilizes and anteriores scapula; raises ribs
External Intercostals
Superior border of one rib to inferior border of infer rib (obliquely, superolaterally to inferomedially) on the outer aspect of the rib cage
Elevate ribs during inhalation
