Skeletal System Test

Front

What is the function of osteocytes in the skeletal system?

Back

Osteocytes are mature bone cells that maintain bone tissue and communicate with other bone cells to regulate bone remodeling.

Front

What type of bone is a sesamoid bone?

Back

A sesamoid bone is a type of bone that is embedded within a tendon, improving the leverage of muscles.

Front

What is the perichondrium?

Back

The perichondrium is a layer of dense connective tissue that surrounds cartilage and plays a role in the growth and repair of cartilage.

Front

What happens to osteoblasts when they become buried in osteoid?

Back

When osteoblasts become buried in osteoid, they differentiate into osteocytes.

Front

What is osteoid?

Back

Osteoid is the unmineralized organic component of bone matrix, primarily composed of collagen and proteins.

Front

What are osteoclasts?

Back

Osteoclasts are bone cells responsible for the resorption of bone tissue, breaking down bone matrix.

Front

What is the periosteum?

Back

The periosteum is a dense layer of vascular connective tissue that covers the outer surface of bones, providing attachment for muscles and tendons.

Front

What is the medullary cavity?

Back

The medullary cavity is the central cavity within long bones that contains bone marrow.

Front

What is the role of chondrocytes in the skeletal system?

Back

Chondrocytes are cells found in cartilage that produce and maintain the cartilaginous matrix.

Front

What is the epiphyseal plate?

Back

The epiphyseal plate, or growth plate, is a hyaline cartilage plate in the long bones of children and adolescents that allows for growth in length.
