2
Q
rhomboid major
A
O= T2-T5 SPs I= medial angle of the scapula A= scapular retraction I= dorsal scapular n.
3
Q
medial rectus
A
O= annular ring I= medial eyeball A= moves eye medially I= Oculomotor
4
Q
lateral rectus
A
O= annular ring (annulus of zinn) I= lateral eyeball A= moves eye laterally I= abducens
5
Q
superior rectus
A
O= annular ring I= top of the eyeball A= elevates eyeball I= oculomotor
6
Q
inferior rectus
A
O= annular ring I= bottom of the eyeball A= depresses eyeball I= oculomotor
7
Q
inferior oblique
A
O= maxillary bone I= inferior lateral eyeball A= elevates and laterally moves eyeball I= oculomotor
8
Q
Iliocostalis
A
O= iliac crest (lumborum); inferior 6 ribs (thoracis); ribs 3-6 (cervicis) I= angle of ribs (lumborum and thoracis); cervical vertebrae C6-C4 (cervicis) A= extension, maintain posture, lateral flexion to same side I= spinal nerves (dorsal rami)
9
Q
longissimus
A
O= TPs of lumbar through the cervical spine I= TPs of the thoracic and cervical spine, ribs superior to origin, mastoid process (capitits) A= extension, lateral flexion, turns head to the same side (capitis) I= spinal nerves (dorsal rami)
10
Q
spinalis
A
O= spines of upper lumbar vertebrae and thoracic vertebrae I= spines of upper cervical and thoracic vertebrae A= extends vertebral column I= spinal nerves (dorsal rami)
11
Q
QL
A
O= iliac crest, lumbar fascia I= 12th rib, TPs of upper lumbar A= laterally flexes vertebral column, fixes 12th rib, assists in breathing and upright posture, when acting together they extend the vertebral column I= T12 and upper lumbar spinal nerves
12
Q
rectus capitis posterior minor
A
O= posterior tubercle of atlas I= inferior nuchal line of the occipital bone A= extend the head and turn it to the same side I= posterior rami of C1
13
Q
rectus capitis posterior major
A
O= SP of axis (C2) I= inferior nuchal line of the occipital bone A= extension and ipsilateral rotation of the head I= dorsal ramus of C1 (suboccipital nerve)
14
Q
obliquus capitis superior
A
O= lateral mass of atlas I= lateral half of inferior nuchal line A= extends head and flexes head to the ipsilateral side I= suboccipital nerve
15
Q
obliquus capitis inferior
A
O= SP of axis I= lateral mass of atlas A= rotation of head and neck I= suboccipital nerve
16
Q
origin of biceps femoris short head
A
Linea Aspera
17
Q
what does the dorsal scapular nerve innervate
A
rhomboids and levator scapularis, C4, C5
18
Q
what is the action of teres major
