Q

Erector spinae (sacrospinalis)

A

largest muscle

extends on each side of spinal column from pelvic region to cranium

  • spinalis, longissimus, and iliocostalis
  • from medial to lateral side, has attachments in lumbar, thoracic, and cervical regions
  • actually made up on 9 muscles

Q

Erector Spinae (sacrospinalis)

A

Origin: spinous process of lower thoracic and lumbar

Insertion: spinous processes of cervical and upper thoracic

Location: posterior

Movements: (spine)

  • Extension (C & L)
  • ipsilateral flexion (C & L)

Muscle is thickest in C and L regions - most movement

Controls forward flexion, extension of the trunk, posterior stability (posture)

17
Q

Rectus Abdominis

A

Origin: pubic crest

Insertion: cartilage of ribs 5-7, Xiphoid process

Location: anterior

Action: trunk flexion

Controls: Posterior pelvic tilt and curvature LS
-flattens lower back.

Definition: 3 depressions - area of tendinous connective tissue

18
Q

External oblique

A

Origin: lateral side of ribs 5-12

Insertion: anterior iliac crest, pubic crest

Location: lateral/antrior. Point upward from medially to laterally

Movements: Flexion (together)

  • ipsilateral flexion
  • contralateral rotation (independently)
19
Q

Internal oblique

A

Origin: Anterior iliac crest

Insertion: Cartilage of ribs 8-10

Location: anterior/medial

Movements (LS): Flexion

20
Q

Transversus abdominis

A

Origin: Lateral 1/3 of inguinal ligament, inner rim of iliac crest, inner surface of costal cartilage of lower 6 ribs, lumbar fascia

Insertion: Crest of the pubis, and the iliopectineal line, abdominal aponeurosis to the linea alba

Location: anterior

Movements (LS):

  • forced expiration by pulling abdominal wall inward
  • compress the ribs and viscera, providing thoracic and pelvic stablity
