Final answer:
A mature cartilage cell is called a chondrocyte, and it resides in spaces called lacunae within the cartilage. An immature cartilage cell is known as a chondroblast, which matures into a chondrocyte as it produces the cartilaginous matrix.
Step-by-step explanation:
A mature cartilage cell is a chondrocyte, while an immature cartilage cell is a chondroblast. Chondrocytes are the primary cells found in cartilage, residing in spaces called lacunae. These cells are responsible for producing and maintaining the cartilaginous matrix, which consists of chondroitin sulfates and proteins that form proteoglycans.
This strong and flexible tissue is a key component in the human body, found in areas such as the fetal skeleton, outer nose, ends of long bones, and intervertebral discs. Unfortunately, due to its avascular nature, cartilage heals very slowly because nutrients need to diffuse through the dense matrix to reach the chondrocytes. A mature cartilage cell is called a chondrocyte, while an immature cartilage cell is called a chondroblast. Chondrocytes are the main cells found in cartilage and are responsible for maintaining the extracellular matrix. They are fully developed and are surrounded by lacunae, which are spaces within the cartilage tissue.
