2. Introduction Abdominis
Muscles
The abdominal muscles
are a crucial component
of the body's core,
providing stability,
movement, and
protection for internal
organs.
They play a significant role
in various functions such
as posture, breathing, and
core strength.
Understanding the
anatomy and function of
these muscles is
essential for maintaining
overall health and
fitness.

3. Types of Abdominal Muscles
 External Oblique
 Internal Oblique
 Rectus Abdominis
 Transversus Abdominis

4. Transversus
Abdominis
 Location: Deepest layer of the
abdominal muscles
 Function: Compresses
abdominal contents, supports
spine and pelvis, stabilizes the
core
 Common Exercises: Planks,
abdominal hollowing, leg
raises

5. Anatomy of the
Transversus Abdominis
 Origin: Iliac crest, inguinal ligament,
thoracolumbar fascia, and costal
cartilages of the lower six ribs
 Insertion: Xiphoid process, Linea alba,
pubic crest
 Nerve Supply:
I. Intercostal nerves (T7-T11)
II. Subcostal nerve (T12)
III. Iliohypogastric nerve (L1)
IV. Ilioinguinal nerve (L1)

6. Structure and
Fiber Orientation
 Horizontal orientation of
muscle fibers
 Relationship with other
abdominal muscles: Rectus
Abdominis, Internal Oblique,
External Oblique

7. Function
 Core Stability: Supports the spine and
pelvis
 Compression of Abdominal Contents:
Assists in breathing, vomiting, and
childbirth.
 Unilateral contraction: Trunk rotation

8. Role in Breathing
 Contribution to Forced Expiration
 Role in Diaphragmatic Breathing

9. Clinical Significance
 Injury and Weakness: Common issues and
symptoms
 Rehabilitation: Exercises to strengthen the
Transversus Abdominis
 Examples: Planks, abdominal hollowing, leg raises
