Anatomy Flashcards
rhomboid minor
O= C7-T1 SPs I= Medial angle of the scapula A= scapular retraction I= dorsal scapular n.
rhomboid major
O= T2-T5 SPs I= medial angle of the scapula A= scapular retraction I= dorsal scapular n.
medial rectus
O= annular ring I= medial eyeball A= moves eye medially I= Oculomotor
lateral rectus
O= annular ring (annulus of zinn) I= lateral eyeball A= moves eye laterally I= abducens
superior rectus
O= annular ring I= top of the eyeball A= elevates eyeball I= oculomotor
inferior rectus
O= annular ring I= bottom of the eyeball A= depresses eyeball I= oculomotor
inferior oblique
O= maxillary bone I= inferior lateral eyeball A= elevates and laterally moves eyeball I= oculomotor
Iliocostalis
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)
longissimus
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)
spinalis
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)
QL
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
rectus capitis posterior minor
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
rectus capitis posterior major
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)
obliquus capitis superior
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
obliquus capitis inferior
O= SP of axis I= lateral mass of atlas A= rotation of head and neck I= suboccipital nerve
origin of biceps femoris short head
Linea Aspera
what does the dorsal scapular nerve innervate
rhomboids and levator scapularis, C4, C5
what is the action of teres major
internal rotator originates at the inferior border of the scapula
what is serratus anterior innervated by
long thoracic nerve, C5, C6, C7, involved as the main protractor
DTR of biceps
C5
DTR of plantar-flexion
S1
what does the sural nerve innervate
the sensory nerve in the calf
what artery is connected to the femoral artery
external iliac artery
the most common way to dislocate your shoulder
abduction and external rotation (anterior displacement)
what controls smooth coordination
basal ganglia
what area of the brain is affected by Parkinson’s
substantia niagra in the basal ganglia
what space does the axillary nerve go through
quadrangular space
what ligament would you find running from the ischium to the sacrum
sacrotuberous
where is the control of respiratory and blood pressure
medulla
what muscle is an important stabilizer in the low back
multifidus
what muscle goes from the sacrum to the greater trochanter
piriformis
if leg length discrepancy, how does the lumbar spine correct to stay neutral
L short leg= right lateral flexion compensation in the spine, L PI ilium
The most common convexity of scoliosis is to what side
Right, c-shaped
what ligament over the biceps tendon
coraco-acromial ligament
iliofemoral ligament
prevents hyperextension
pubofemoral ligament
prevents abduction and external rotation
ischiofemoral ligament
prevents internal rotation, extension
what muscles have dual innervation
triceps, adductor Magnus, biceps femoris, flexor digitorum superficialis, psoas
