A&P Chapter 6 Review

Front

What are chondrocytes?

Back

Cells encased in small cavities (lacunae) within a jelly-like extracellular matrix, responsible for cartilage formation.

Front

What is fibrocartilaginous callus formation?

Back

A stage in bone healing where fibroblasts, cartilage, and osteogenic cells begin the reconstruction of bone.

Front

What is the structure of a long bone?

Back

A long bone has a shaft (diaphysis), bone ends (epiphyses), and membranes.

Front

What is fibrocartilage?

Back

A type of cartilage that contains thick collagen fibers, providing great tensile strength; found in menisci of the knee and vertebral discs.

Front

What is the perichondrium?

Back

A layer of dense connective tissue that surrounds cartilage, providing support and protection.

Front

What is the role of fibroblasts in bone healing?

Back

Fibroblasts are cells that synthesize the extracellular matrix and collagen, playing a crucial role in the healing process.

Front

What is the function of the endosteum?

Back

A thin membrane lining the medullary cavity of bones, involved in bone growth, repair, and remodeling.

Front

What are osteogenic cells?

Back

Stem cells found in the periosteum and endosteum that differentiate into osteoblasts, responsible for bone formation.

Front

What is hyaline cartilage?

Back

A type of cartilage that is smooth and glassy, providing support and flexibility; found in the nose, trachea, and at the ends of long bones.

Front

What is the difference between the diaphysis and epiphysis of a long bone?

Back

The diaphysis is the shaft of the bone, while the epiphysis refers to the ends of the bone.
