Organization of the Animal Body | Back to Top. Animals are multicellular heterotrophs whose cells lack cell walls. At some point during their lives, all animals are capable of movement, although not all animals have muscles they use for this. Organs are composed of tissues, which are in turn composed of cells.

What animals don’t have a muscular system?
Some animal groups don’t have any muscles at all, as they branched off from the evolutionary path before muscle cells evolved. Yet these animal groups — for instance, the sea sponges — are not incapable of movement. Sponges are able to contract without muscles.

What is muscle in human body?
There are about 600 muscles in the human body. Muscles have a range of functions from pumping blood and supporting movement to lifting heavy weights or giving birth. Muscles work by either contracting or relaxing to cause movement.
What causes muscles to move?
A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.
