Cards

Term

Transverse Adominis

[image]

Definition
  • Deepest layer of the adominal wall
  • Fibers run horizontally
  • "clinches waiste"-belly button to spine
  • COMPRESSION
  • Works activate crunches/contraction

Inguinal ligament. Iliac crest, thoraculumbar fascia, inner surfaces of ribes 7-12, aponeurosis/linea alba

 

Term
  • [image]

 

Definition
  • Compression of Abdomen
  • Assist in flexion
  • Lateral Flexor
  • Contralateral rotation

Inguinal ligament, thoraculmbar fascia, iliac crest, lower ribs/costal cartilage

 

Term
[image]
Definition
  • Compression of the abdomen
  • Assist in Flexion
  • Lateral Flexor
  • Ipsilateral Flexion

 

Inguinal ligament, thoraculmbar fascia, iliac crest, lower ribs/costal cartilage, Aponereurosis to midline in front

 

Term

Quadratus Lumborum

[image]

Definition
  • -Lateral Stabilizer of the spine during flexion of the spine and legs
  • Bilateral contraction will extend the lumbar vertebrae to stabilize front leg extensions
  • Unilateral contraction=Side port de bras and hip isolations

Posterior iliac crest. RIB 12. Tranverse processes of lumbar spine.

Term

Rectus Abdominus

[image]

Definition
  • First layer of the abdominal muscles
  •  Most medial
  • Fibers run vertically
  • 6th pack definition
  • unilaterateral participation in lateral flexion

Pubic crest to xiphoid process and costal cortilage (ribs 5-7)

Term
Linea Alba
Definition
White line of tissue that connects the rectus abdominus
Term

Pyramidalis

[image]

Definition
Triagular muscle that flexes and lifts. "deep flexor"
Term

Iliopsoas(Iliacus and Psoas)

[image]

Definition
  • The Deep Hip/Spine Flexor
  • Iliacus does NOT attach to the spine
  • Psoas do Attatch to the spine
  • Prevents over working of the quads

Iliacus: Iliac fossa to the less trochanter of the femur

Psoas: Lumbar spine to less trochanter of the femur

 

Term

Semispinalis

[image]

Definition
  • Fibers run Diagonally
  • Bridges larger groups/segments at a time
  • Cervical and Thoracic Regions

Transverse processes to Spinous process on vertebrae located above (Mid thorax to posterior skull)

 

Term

Multifidus

[image]

Definition
  • Fibers run diagonally
  • Bridgess 2-3-4 segments at a time
  • Cervical, Thoracic, and Lumbar regions

Transverse processes to spinous process on vertebra located above

(Sacrum to C2)

Term

Rotatores

[image]

Definition
  • Ribers run Diagonally
  • Bridges 1-2 Segments at a time
  • Thoracic Region only

Tranverse processes to Spinous Process on vertebrae located above

(T1-T12)

Term
Ipsilateral Rotation
Definition
Same Side Rotation
Term
Contralateral Rotation
Definition
Opposite side rotation
Term

Erector Spinae Group

[image]

Definition

Very Toned!

-Spinalis

-Longisimus

-Iliocastalis

Term

Spinalis

[image]

Definition
  • Most Medial
  • Fibers run Veritcally
  • Unilatreally in cervical region will contrubute to lateral flexion and rotation
  • Bilaterally they will extend spine and can hel lengthen the cervical region of the neck

Spinous processes (cervical/thoracic only)

Term

Longissimus

[image]

Definition
  • The middle middle muscle
  • Fibers run vertically
  • Aponeurosis attacment at the sacral spine

Tranverse processes and bodies of the vertebrae (Base of skull to lumbar spine)

Term

Iliocastalis

[image]

Definition
  • Most Lateral
  • Fivers run Vertically
  • Aponeurosis attachment at sacral spine

Iliac crest/lumbar fascia to posterior aspects of ribs, tranverse processes of lower cervical vertebrae

(low cervical to lumbar spine)

Term

Scalenes

[image]

Definition
  • Anterior
  • Middle
  • Posterior
Term

Anterior Scalene

[image]

Definition
  • Lateral Flexion
  • Flexion and contralateral rotation

Cervical transverse processes to Rib 1

Term

Middle Scalene

[image]

Definition
  • Lateral Flexion

Cervical transverse processes to Rib 1

Term

Posterior Scalene

[image]

Definition
  • Lateral Flexion
  • Flexion and contralateral rotation

Cervical transverse processes to Rib 2

Term

Sternocleidomatstroid

[image]

Definition
  • The "chicken neck chord"
  • Flexion plus lateral flexion and contralateral rotation

Mastoid process of skull to medial clavical of sternum

Term

Splenius Capitis

[image]

Definition
Occipital bone to spinous process of C7-T6
Term

Splenius Cervicis

[image]

Definition
Transverse processes of C1-C3 to spinous processes of T5-T7
Term
