Lab Practical 1 Actions Flashcards
Splenius Cervicis
laterally flex & rotate neck; bilaterally extend neck
Splenius Capitis
laterally flex head & rotate face to side; bilaterally extend head
iliocostalis lumborum
extension, lateral flexion, rotation of L spine; lateral movement of pelvis
iliocostalis thoracis
extension, lateral flexion T spine
iliocostalis cervicis
extension, lateral flexion, rotation lower C spine
longissimus thoracis
lateral flexion T spine & ribs (L spine inadvertently); bilaterally act in extension of T & L spine, hold T & L spine erect (increases L lordosis); lateral movement of pelvis
longissimus cervicis
lateral flexion of neck; bilaterally extend neck
longissimus capitis
rotate & laterally flex head; bilaterally extend head
spinals thoracis
extend T spine
spinalis cervicis
lateral flexion & rotation of C spine; bilaterally extend neck
spinalis capitis
lateral flexion & rotation of head; bilaterally extend head
semispinalis thoracis
extension, rotation, & lateral flexion of upper T & lower C spine; bilaterally extend T spine
semispinalis cervicis
extension, rotation, & lateral flexion of C spine; bilaterally extend neck
semispinalis capitis
turns face to side; bilaterally extends head (neck inadvertently)
rectus capitis posterior major
turns face to side; bilaterally extends head
rectus capitis posterior minor
extends head
obliquus capitis superior
lateral flexion of head; bilaterally extends head
obliquus capitis inferior
turns face to side
quadratus lumborum
steadies origin of diaphragm; when pelvis is fixed, it will laterally flex the L spine; bilaterally extends the L spine; stabilizes & depresses the 12th rib
serratus posterior superior
elevates upper 5 ribs in inspiration
serratus posterior inferior
draws lower 4 ribs down & back; forced inspiration
longus colli
flexion & extension of neck; rotation to the contralateral side
longus capitis
flex the head
rectus capitis anterior
flex the head
rectus capitis lateralis
laterally flex the head to ipsilateral side
