Answer:
The CELL THEORY, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin's theory of evolution (1859), Mendel's laws of inheritance (1865), and the establishment of comparative biochemistry (1940).
Ultrastructural research and modern molecular biology have added many tenets to the cell theory, but it remains as the preeminent theory of biology. The Cell Theory is to Biology as Atomic Theory is to Physics.

Answer:
External and internal abdominal obliques, transverse abdominal, and rectus abdominis
Explanation:
The abdominal wall compression involves the action of four muscles:
- External abdominal obliques
- Internal abdominal obliques
- Transverse abdominal
- Rectus abdominis
- The external oblique, internal oblique, and transverse abdominis are the components of the lateral abdominal wall and the rectus abdominis is located medially.
- The rectus abdominis muscle helps in stabilizing side bending and supports the trunk.
- The abdominal obliques are involved in the rotation of the torso and bending along with the compression of the abdomen.
- The transverse abdominal helps in respiration.
- Besides there normal and routine functions all these muscles work together in abdominal compression.
