19
Q

why are the abdominal muscles in several directions?

A

strong in different directions, fiber directions show where it is strong

20
Q

how are the superior abdominal muscle (ext. abdominal oblique)?

A

origin is the lower rib, insertion is at the top of the rectus, general rule is pelvis is usally where things originate and insert more superior, this

21
Q

what are Subdivision of the Thoracic Group?

A

Externalintercostal/InternalIntercostal/Transversus thoracis

22
Q

the three body wall sub divisions, abdominal , thoracic, and perineal are all what to each other?

A

homo, the superfical layers,the intermediate and deep are all homo to each other

23
Q

the intercostals and abdominals muscles go the same fiber direction?

A

yes! besides the transverese throacic which is kind of spiderwebby, spread out radically

24
Q

all deep layers of perional abdominal and intercostals all are what?

A

have to do something with transverse

25
Q

Perineal Group,Superficial

A

Urogenital Diaphragm (External Anal Sphincter concious control//Deep Transverse Perineal)

26
Q

Subdivision of the Perineal Group/Intermediate

A

Pelvic Diaphragm:- Coccygeus- Levator ani

27
Q

Subdivision of the Perineal Group/Deep

A

Transversalis Fascia/Deteriots as you get older, consistent deepest layer,

28
Q

Subdivision of the Neck Region, whats left?

A

Scalenes are what are left

29
Q

The Diaphragm was originally what?

A

hypaxial cervical musculature

30
Q

how did the diaphragm move down?

A

Heart above your headto throaic, heart pushes diaphragm then ends up down, removed it from cervical region

31
Q

strap muscles: rectus abdominis

A

Paired muscle, location and shape/Rectus straight muscle of the abdomin/ Strap like muscles, plevis to head, muscles here are homo. To each other

32
Q

what is a rectus sheath?

A

Sheath of connective tissue, surrounding muscle fibers of rectus abdominos

33
Q

where does the rectus sheath meet?

A

left and right are meeting at midline at the lina alba in between rectus abdominos where sheaths meet each other

34
Q

Geniohyoid,

A

Named after origin and insertion/Genu( chin) inserting to hyoid (hyoid muscle)

35
Q

rectus sheath fibers go which way

A

no consistent, extra support on the outside, move tendons all on the superficial aspect

36
Q

arculate line in the abdominos does what?

A

marks charge deep leaf of rectus sheath, go to the superficial aspect of the abdominoal muscles , inferior

37
Q

Strap musclesRectus Series/Omohyoid

A

Sholder-hyoid, can depress hyoid

38
Q

Strap muscles/Rectus Series/Sternohyoid/Sternothyroid

A

Different insertions, different actions, two different muscles/Even though they have same origin

39
Q

name three Prevertebral Musculature (On the anterior aspect of your transvere processes, deep inside)

A

Longus capitis/Longus colli/Quadratus lumborum

40
Q

longus capitis(lateral to longus colli)

A

origin: cervical vertbrae insertion:base of skull

41
Q

longus colli

A

origin: bodies of vertbrae from throac/insertion:onto your cervical vertbrae for neck

42
Q

Quadratus lumborum

A

short of rectangular in shape/ abduct vertebral column, depresses rib 12 origin:iliac crest, lower lumbar verterbrae I: T12,l1-4,rib 12

43
Q

Attaches to pubic bone, is what quad?

A

Cranial/Ventral:(Superior/Anterior)

44
Q

Attaches to Ischium, is what quad?

A

Caudal/Ventral/Inferior/Anterior)

45
Q

Attaches to upper part of ilium is what quad? iliac crest, medial surface of ilium, ant, ilium spine

A

Cranial/Dorsal

46
Q

attaches the shaft/body of the illium and the lateral surface of the illium, out to the sides

A

Caudal/Dorsal –Inferior/Posterior)
