Contract and Relax
In shot put, major muscles involved are the deltoids, pectoralis major, triceps brachii, and core muscles. The actions of the joints include shoulder abduction and flexion, elbow extension, and trunk rotation. These muscles and joint actions are crucial for generating power and distance in shot put throwing.
The two major proteins that make muscles move are actin and myosin. These proteins slide past one another during muscle contractions, generating the force that allows muscles to shorten and generate movement.
Antagonists are muscles that resist the actions of agonist muscles and cause movement in the opposite direction. They help control the speed and range of motion of a joint during movement. Working together, agonist and antagonist muscles create balanced movement patterns in the body.
Muscles involved in pushing hard against a wall include the chest (pectoralis major), shoulders (deltoids), triceps, and core muscles for stabilization and power generation. This action primarily engages the upper body muscles.
Two muscles found in the thoracic wall of both cats and humans are the external intercostal muscles, which help with inhalation by expanding the ribcage, and the internal intercostal muscles, which aid exhalation by compressing the ribcage.
There are twelve muscles in the face that make it possible for a person to smile. Other muscles can be used along with smiling that can make this number jump to as many as twenty-two.
One of the two muscles that make up the front part of the choroid is the ciliary muscles. Another one that makes up the choroid is the iris.

Reflex actions do not require thinking, nor do the actions of involuntary muscles.

Muscles never "push"; they can only "pull".The only power that muscles have is to contract or relax. When they contract, they pull. Most bones have two or more sets of muscles, and each muscle pulls in one direction; in sets, the muscles can work together or oppose each other, which account for all the actions that an animal or person can perform.
Peristalsis is primarily driven by two sets of muscles in the digestive tract: the circular muscles and the longitudinal muscles. The circular muscles constrict and relax to propel food forward, while the longitudinal muscles shorten and widen the segment of the intestine, facilitating the movement. Together, these muscle actions create coordinated waves that push contents through the digestive system.
The actions skeletal muscles can perform are: flexion, extension, abduction, adduction, rotation, elevation, and depression.
Skeletal muscles do form the passageways in the body, but their actions are very rarely involuntary. More often than not, the actions of the skeletal system are performed because the brain sends a signal to those muscles and forces them to move.
