Skeletal System

The correct answer lists the main functions of the skeleton, which include movement, support, protection, making blood, and storage.

The femur, also known as the thigh bone, is the longest bone in the human body, located in the upper leg between the hip and the knee.

The periosteum is a fibrous membrane that surrounds the outer surface of bones, providing support and protection.

Compact bone is the dense and hard outer layer of bone tissue, while spongy bone is the inner layer that consists of a network of trabeculae. Soft and flexible part of bone tissue refers to cartilage, and a fluid-filled cavity within bone tissue is known as the bone marrow.

Spongy bone, also known as cancellous bone, is found at the ends of long bones and inside flat bones like the skull and sternum. It provides structural support while being lightweight.

Bone marrow is responsible for the production of blood cells, while cartilage, synovial fluid, and ligaments have different functions in the body.

The clavicle is commonly known as the collarbone due to its location in the body and shape.

The main function of the Skeletal System is to provide structural support for the body, protect internal organs, produce blood cells, and store minerals such as calcium.

An adult human typically has 206 bones in their body, but it may vary slightly from person to person due to the fusion of certain bones during development.

Babies are born with around 300 bones, which eventually fuse together as they grow, resulting in the adult human skeleton of 206 bones.
