Animals differ from plants in that animals can move from one place to another. Two systems that work together make this possible. These are the muscular and skeletal systems. When combined, we call it the musculoskeletal system.
Advanced Animal Science
Animals have different types of musculoskeletal systems. Arthropods, or jointed animals, include insects and spiders as well as crustaceans such as crabs and lobsters. These animals have an exoskeleton. This means that some form of hardened shell, or an exterior (exo) skeleton, covers their interior parts. Specialized skin cells produce these shells in a similar way that our nails grow. Exoskeletons are made of chitin, a type of complex sugar.

In this image are photographs of a variety of arthropods including a yellow and black wasp, two colourful beetles, a black and white butterfly, a greyish crab, a reddish brown lobster, a pale pink shrimp, a dark brown pillbug, two reddish brown centipedes, a water spider with an air bubble on its abdomen and two other orangish spiders.

). This helps to reinforce the shells. The disadvantage of using calcium carbonate is that it can dissolve in warm or acidic waters. This is the reason why coral reefs and molluscs are sensitive to ocean acidification.
Shown is a photograph of a large assortment of seashells. There are offwhite clam shells, pink and white banded scallop shells, spiky whelk shells and several types of colourful snail shells.
One of the major drawbacks of exoskeletons is that they need to be replaced as the animal grows. This is done through the process of moulting. During moulting the animal is not well protected because the new exoskeleton is not hard like the old skeleton. The skeleton hardens over time.
Animal Bone Identification
A second type of musculoskeletal system is a hydrostatic skeleton. This is a system used by jellyfish, octopuses, and earthworms. In this system, water pressure known as hydrostatic pressure is used to make different parts of the body become harder or softer. They do this by pumping water into a compartment called the coelom using muscular “water pumps.” These water pumps are also what move the suction cups of octopuses!
The third and final type of musculoskeletal system is the one you should be familiar with. Endoskeletons are located inside the body. The word “endo” means inside. Scientists consider that a few animals, like starfish, also have an endoskeleton because skin covers skeletal elements. However, most animals bearing endoskeletons are vertebrates, animals with a backbone.
Vertebrate animals are a group that include fish, amphibians, reptiles, mammals and birds. All of these animals have skeletons made from bone, except for cartilaginous fishes like sharks and rays, whose skeletons are made from cartilage.

The skeleton has several important jobs. One job is to provide protection for internal organs. A good example of this is your rib cage. The bones of your rib cage protect your heart and lungs as well as part of your liver and stomach. Can you think of other bones that protect important body parts?

Another important job of the skeleton is to provide support for the body and allow for movement with the help of muscles attached to bones.

If you have ever been to a natural history museum, you have probably seen animal skeletons. Have you ever wondered why people are so interested in skeletons? Studying animal skeletons is a big part of understanding the evolution of species. It also helps scientists to classify different groups of animals. For some extinct species, like dinosaurs, fossilized skeletons are all that remain of them. Comparing fossil skeletons to the skeletons of living animals helps us to understand some pretty interesting things, such as the evolution of birds from dinosaurs!

Vertebrates all have bony skulls to protect their brains. Most also have jaws that work together with bones in the skull to help them get and process food. Skulls and jaws sometimes, but not always, contain teeth.
Skeletons Of Animals/humans
Drawing of a human skull. The cranium and facial bones are show separately. The adult cranium, facial bones and mandible are made up of 22 bones.
All vertebrates have a column of bones along their backs called vertebrae. This is where the name of this group of animals comes from! We call this group of vertebrae the vertebral column or spine. Vertebrae help to protect the spinal cord, which is part of the nervous system.
Below this is the sacrum. In humans, this is a triangular bone that is formed when five vertebrae fuse together during early adulthood. The bones of the pelvis connect to the sacrum.

Forming the end of the spine are the tail bones. Humans have a coccyx that is formed from four fused bones. Instead of having a coccyx, animals with tails have more vertebrae called caudal vertebrae.

Did you know? Mammals, including giraffes and whales, all have 7 vertebrae in their necks. Manatees and sloths are the exception. They tend to have one or two more neck vertebrae.
Anatomical Terms Of Bone
Humans have 12 rib bones on each side of the body. The 7 bones closed to the head are called true ribs. These bones connect directly to a bone called the sternum. We usually call this the breast bone. The other 5 ribs are called false ribs because they only indirectly connect to the sternum. Ribs 11 and 12 are called floating ribs because they do not connect with the sternum at all.
All vertebrates have the same bones in their forelimbs. These are the humerus, radius, ulna, carpals, metacarpals and phalanges. They are the bones of the arm, wrist and hand.
Even though they have the same bones, their forelimbs can look very different. These differences allow the animals to move in different environments such as on land, in the water and in the air.

Animals that have forelegs also tend to have hindlegs. The exception to this rule are whales, dolphins, porpoises and siren salamanders, which all have only forelimbs.
Connected to the femur is the knee bone, known as the patella, as well as the tops of the tibia and fibula. Similar to the forearms, at the ends of these bones are the tarsals, metatarsals and phalanges - better known as your ankles and feet.
Did you know? The largest bone in the human body is the femur. The biggest bone ever found was a femur from a sauropod dinosaur that was 6.5 feet long!

The number of bones that you will have as an adult, is NOT the same number of bones that you were born with. A newborn's skeleton is made up of 270 bones. During growth, some bones, such as the ones in the skull, fuse together. Adults typically have 206 bones.
