Pelvic size generally correlates with the size of the animal and varies with the structure of the animal and how it uses it's limbs for locomotion. The size, structure and orientation of a bipedal animal's pelvis is allows for vertical attachments of the bones and muscles of the legs...
Animals have similar muscles to those in the human body, but there can be variations in the size and arrangement of muscles based on the species. All animals have muscle tissue composed of muscle fibers that contract to generate movement. While the specific muscles may vary in name and function between humans and animals, the overall structure and purpose of muscles are comparable.
The nervous system, specifically the motor cortex in the brain, is responsible for coordinating muscle movements that control body locomotion. The brain sends signals through the spinal cord to activate the muscles needed for walking, running, or any other form of movement.
The function of arrector pili muscles in animals other than humans is to keep animals with fur warm. The muscles do this by contracting and raising the fur away from the skin. This results in the creation of a space for warm air near the skin.
Liver and muscles store carbohydrate .
The way the muscles are attached to the bones is what facilitates locomotion. The muscles contract which makes the bones move and creates locomotion.
Muscles move your bones, therefor making locomotion possible.
Bipedal locomotion consists of movement using two legs. This form of locomotion is utilized by humans and certain other animals for walking, running, and jumping. It requires coordination of multiple muscles and joints to maintain balance and stability while in motion.
Non muscular movement occur in animals that do not need to contract and expand muscles in order to move. The two type of locomotion that do not need muscles include ciliary and amoeboid movements.
Locomotion
Animals can have muscles.
Muscles do is to command the bones to move and you need food and energy to move around.
Because they have no structures like muscles to move with. They are rooted to the ground.
Bones are not essential for locomotion . Earthworm move by using circular and longitudinal muscles along with setae and shoe accordion like locomotion .
In animals with endoskeletons, muscles surround the skeleton. In animals with exoskeletons,the skeleton surrounds the muscles.
The musculoskeletal system (muscles pulling on bones) controlled by the nervous system
Locomotion ... it acts as a lever system for the muscles to work on.
