Muscles in the body enable movements through contractions. These contractions occur when muscle fibers shorten and generate force, allowing for various movements such as walking, stretching, and flexing. The coordinated efforts of different muscle groups contracting and relaxing result in smooth and controlled body movements.
Movable joints enable the body to make a wide range of movements.
Muscle cells, or myocytes, are the primary cells that contract to facilitate movement in animals. There are three main types of muscle cells: skeletal muscle cells, which enable voluntary movement; cardiac muscle cells, which control heart contractions; and smooth muscle cells, which manage involuntary movements in organs. These cells work together to produce coordinated contractions that enable locomotion, circulation, and various bodily functions.
You are possibly thinking of the movements called peristalsis which pass along your gut. Peristalsis is a wave of contraction and relaxation of circular and longitudinal muscles which passes along the wall of the gut. Its function is to push food along.This movement could be described as similar to the contraction and relaxation of muscles in the body wall of worms during locomotion.
Hinge joints in the body, like the elbow and knee, allow movement in one direction like a door hinge. They enable flexion and extension movements, such as bending and straightening. These movements are possible due to the structure of the bones and the ligaments that stabilize the joint.
Processes that facilitate locomotion include muscular contractions to move the body, skeletal structure to provide support and leverage for movement, and coordination of the nervous system to control and initiate movements. Additionally, feedback from sensory systems helps adjust movements to the environment and maintain balance during locomotion.

There will be contractions and expansions of circular and longitudinal muscles passing through the segmented body
Muscular contractions.
These can be muscle contractions or spasms.
Smooth muscle tissue is responsible for contractions that account for the movement of organs in the entire body. This type of muscle tissue is involuntary, meaning it contracts without conscious control, and is found in the walls of hollow organs like the stomach, intestines, and blood vessels. Smooth muscle contractions help with processes like digestion, circulation, and breathing.
The muscular system is involved in contractions and creating body heat.
Approximately 15 movements per minute

The maintenance of body position in response to sudden movements like rotation, acceleration, and deceleration is achieved through the coordination of the vestibular system, proprioceptive feedback from muscles and joints, and visual input. These sensory inputs help the brain adjust muscle contractions to keep the body balanced and stable during sudden movements.

Alpine skiing primarily involves isometric and concentric muscular contractions. Isometric contractions stabilize the body and maintain posture while navigating turns, allowing skiers to hold their stance against the forces of gravity and friction. Concentric contractions are used during movements like pushing off or accelerating, enabling skiers to generate power as they carve through the snow. Eccentric contractions also play a role, especially when absorbing shocks and controlling speed during descents.
