Textbook Question

Name the primary cell type in connective tissue proper; in cartilage; in bone.

Verified step by step guidance

Understand that connective tissue is categorized into different types based on structure and function: connective tissue proper, cartilage, and bone.

Identify the primary cell type in connective tissue proper. These are fibroblasts, which are responsible for producing fibers (like collagen and elastin) and ground substance in the extracellular matrix.

Determine the primary cell type in cartilage. These are chondrocytes, which are specialized cells that produce and maintain the cartilaginous matrix.

Recognize the primary cell type in bone. These are osteocytes, which are mature bone cells embedded in the bone matrix and play a role in maintaining bone tissue.

Review the functional roles of these cells: fibroblasts in connective tissue proper provide structural support, chondrocytes in cartilage ensure flexibility and resilience, and osteocytes in bone contribute to strength and mineral storage.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Connective Tissue Proper

Connective tissue proper is a category of connective tissue that provides support, elasticity, and metabolic functions. It is composed of a variety of cell types, including fibroblasts, adipocytes, and immune cells, embedded in an extracellular matrix. The primary cell type in connective tissue proper is the fibroblast, which produces collagen and other fibers that contribute to the tissue's strength and flexibility.

Cartilage

Cartilage is a flexible connective tissue found in various parts of the body, including joints, the rib cage, and the ear. It is characterized by a dense matrix rich in collagen and proteoglycans, which provide resilience and support. The primary cell type in cartilage is the chondrocyte, which is responsible for maintaining the cartilage matrix and ensuring its health and integrity.

Bone Tissue

Bone tissue is a rigid form of connective tissue that provides structural support, protection for organs, and a reservoir for minerals. It is composed of a mineralized matrix and various cell types, including osteoblasts, osteocytes, and osteoclasts. The primary cell type in bone is the osteoblast, which is involved in the formation and mineralization of bone, playing a crucial role in bone growth and repair.
