Muscles that flex the vertebral column

A 
Rectus Abdominis
External Oblique

Q

Intertraversarii origin and insertion

A

Cervical: Spans transverse processes of C2-C7
Lumbar: Spans transverse processes of L1-L6
Inserts into the transverse process direction above

17
Q

Rectus abdominus actions

A

Flexion of the vertebral column

Posteriorly tilt the pelvis

18
Q

Transverse abdominus insertion

A

Abdominal aponeurosis to linea alba

19
Q

Serratus posterior inferior actions

A

Depress ribs during exhalation

20
Q

Longissimus origin and insertion

A

O: Thorocolumbar Aponeurosis
I: Lower 9 ribs, Transerse process all the way to Mastoid Process

21
Q

Oblique capitis superior and oblique capitis inferior same attachment site

A

Obliquus Capitis Inferior Inserts at the Transverse process of C1
Obliquus Capitis Superior Originates at the Transverse process of C1 (Atlas)

22
Q

Rectus femoris origin

A

AIIS

23
Q

Quadriceps insertion

A

Tibial Tuberosity

24
Q

Tilting of the pelvis by the hamstrings

A

Posterior tilt

25
Q

Muscles of the pes anserine tendon

A

Sartorius, Gracilis, Semitendinosus

26
Q

Glute maximus actions

A

Abduct the hip
Laterally rotate the hip
Extend the hip
Lower Fibers: Adduct the hip

27
Q

Actions of gracilis vs adductor group

A

Gracilis is the only adductor to cross the kneecap so it is the only adductor to:
Medially rotate the knee when flexed
Flex the knee
(Along with the other adductors it is involved in Adduction and Medial rotation of the HIP, but it is not involved in assisting the flexion of the hip)

28
Q

Structures that make up the femoral triangle

A

Inguinal Ligament, Adductor Longus, Sartorius (I Ain’t Scared - IAS)

29
Q

Actions of the piriformis

A

One of the 6 Lateral rotators
Laterally rotate the hip
Abduct the hip when the knee is flexed

30
Q

Diaphragm nerve innervation

A

Phrenic Nerve

31
Q

Hamstrings origin

A

Ischial Tuberosity (and the Lateral lip of lines aspera for the Short head of Biceps Femoris)

32
Q

Rectus femoris actions

A

Extend the knee

Flex the hip

33
Q

Bicep femoris insertion

A

Head of the Fibula

34
Q

Glute medius actions

A 
All: Abduct the hip
Posterior: Laterally rotate the hip
Extend the hip
Anterior: Medially rotate the hip
Flex the hip
35
Q

Sartorius origin insertion

A

O: ASIS
I: Pes Anserinus Tendon
(It’s long and does a lot of things)

36
Q

Psoas major origin insertion

A

O: Bodies and transverse processes of Lumbar Vertebrae
I: Lesser Trochanter
