A
- Compress abdomen
- Flex & rotate vertebral column
- Lateral bending
19
Q
Rectus Abdominus
A
- Compress abdomen
20
Q
Transversus Abdominus
A
- Compress abdomen
21
Q
Inguinal Ligament
A
- Formed from layers of abdominal wall
- Runs iliac spine to pubis symphysis
22
Q
Linea Alba
A
- Center of abdomen
- Runs xyphoid process to pubic symphysis
- Doesn’t adhere to fascia layers
23
Q
Linea Semilunaris
A
- Attachment of external & internal obliques
- Onto aponeurosis
24
Q
Tranversalis Fascia
A
- Deep layer of thin fascia
- No longer have rectus sheath
25
Arcuate Line
- Above posterior & anterior sheaths
- Fascial division within abdomen
- Below no sheaths
26
Arcuate Line Importance
- Surgical landmark
- C section
27
Diastasis Recti
- Separation of fascia at linea alba
- Increases with abdominal strain

Diastasis Recti Treatment
- Stop abdominal exercise
- Post pregnancy, exercise & physio
- Sometimes surgery
30
Inspiration Muscles
- Relaxation of diaphragm & external intercostals
31
Active Expiration Muscles
- Contraction of internal & innermost intercostals
