It usually provides slow, low-energy contractions and it does not tire. In a wolf, the smooth muscle lines the internal organs which include the intestine, bladder, uterus and large blood vessels. There are three types of muscles when it comes to most animals. Their strong neck muscles are used to hold up their head and powerful jaw muscles give them their ferocious bite when attacking prey.
The wolf is a very muscular animal as it uses strong trunk muscles to drive their slender legs, allowing them to run fast and leap far. These also play an important role in maintaining calcium levels in body fluids. They have long branches that reach out from the cell body and communicate with neighbouring osteocytes. Osteocytes cells do not secrete the osteoid bone matrix, but are surrounded by it. They are quite large, with multiple nuclei and are located in the membrane that lines the inner cavity of the bone. Osteoclasts cells are the cells that dissolve bone tissue. This substance is then mineralized with substances like calcium and phosphate, which forms the substance we know as bone. They only have one nucleus and function by secreting a substance known as the bone matrix. Osteoblasts cells are the bone cells that are responsible for bone formation. They mature into the osteoblasts which is another type of specialized bone cell. Osteoprogenitor cells are immature cells that are located in the bone marrow and membrane. These are the osteoprogenitor cells, osteoblasts cells, osteoclasts cells and osteocytes cells. There are four specialized cells that make up the bones of a wolf. It includes the Skull which protects the brain, Scapula(shoulder blade), Vertebrae, Pelvis (hip), Tail-bone, Knee joint, Elbow joint, Radius, Ulna, Metacarpal (toe bone), Femur, Hock (ankle joint) and Sternum. In a wolf’s skeletal system, the whole bone structure is an organ itself. This feature makes biting through tough meat of their prey easier. This bone is the hardest, strongest and densest bone in the wolf’s body. This unique feature is different to in other mammals as the lower jaw of other mammals contain additional bones. On the other hand, the lower jaw of a wolf is just one bone, the dentary. The skull at first is made of many bones, though over time they join together and develop. The skull is another important part of the skeletal system because it protects the brain. Due to the wolf having considerably long legs, they are able to take longer strides, which make chasing prey much easier. The bones inside the toes are short but the bones of the legs are long. They have long limbs and a deep chest to accommodate large lungs. Wolves are running mammals so this means that their skeleton is structured accordingly. They also require a strong bone structure because it gives them the power to take down large prey such as caribou. Their bones need to be strong as it allows them to push off more easily, especially through deep snow. The Arctic wolf’s body is built for long-distance travel and endurance.
