Cells that reside in a specific connective tissue type for an extended period of time are called
wandering cells.
resident cells.
fixed cells.
stem cells.
transitional cells.
The correct answer and explanation is:
The correct answer is resident cells.
Resident cells are the cells that reside in a specific connective tissue type for an extended period of time. They are a stable population of cells that stay in the tissue and perform tasks essential for maintaining the structure and function of the tissue. These cells include fibroblasts, adipocytes, and macrophages, among others.
Fibroblasts are the most common resident cells in connective tissue. They are responsible for producing and maintaining the extracellular matrix, which provides structural support to the tissue. These cells are also involved in the synthesis of collagen and elastin fibers, which contribute to the strength and flexibility of the tissue.
Adipocytes are fat cells found in connective tissue, especially in adipose tissue. They store energy in the form of fat and act as insulation to help regulate body temperature. These cells are crucial for energy storage and metabolic regulation.
Macrophages, although they can be classified as a type of white blood cell, are also considered resident cells in connective tissues. These cells are involved in immune responses, including the removal of dead or damaged cells, pathogens, and other debris. While macrophages can wander in and out of tissues during immune responses, their resident forms are important for maintaining tissue homeostasis.
Wandering cells, on the other hand, are typically short-lived and migrate into tissues as needed, especially during inflammatory responses or when an immune reaction is required. These cells include leukocytes (such as neutrophils and lymphocytes) that temporarily leave the blood to infiltrate tissues when responding to injury or infection.
Overall, resident cells maintain the integrity and function of connective tissues, providing structural support and taking part in tissue repair and immune responses when needed.
