skin
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...
swaying or thrashing of the longitudinal muscles on one side contracting while the other side expands causing s shaped curves
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.
Myotonic animals will have enlarged muscles. Enlarged muscles (called Hypertrophy of muscles) will mean the animal will have a better carcass at slaughter . These animals may dress out better however they have an inability to escape predators because of the myotonia.
muscles and sinew and in some cases cartalige
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.
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
Paired setae
Animals can have muscles.
Muscles do is to command the bones to move and you need food and energy to move around.
The muscles are the functional partners for motion and locomotion; movement of the body.
Because they have no structures like muscles to move with. They are rooted to the ground.
The skeleton The muscles The nervous system.
The mesoderm tissue can develop into various structures such as muscles, bones, blood vessels, kidneys, and reproductive organs in the human body.
Bones are not essential for locomotion . Earthworm move by using circular and longitudinal muscles along with setae and shoe accordion like locomotion .
