9. What cell type produces and maintains the majority of extracellular matrix components of connective tissue?

Fibroblast

Macrophage

Mesenchymal cell

Mast cell

Plasma Cell

Fibroblasts are the primary cell type responsible for producing and maintaining the extracellular matrix components of connective tissue. They secrete various proteins and fibers, such as collagen, elastin, and fibronectin, which provide structural support and elasticity to the tissue. Fibroblasts also play a crucial role in wound healing and tissue repair by producing new extracellular matrix components. Macrophages, mesenchymal cells, mast cells, and plasma cells have different functions and are not primarily involved in the production and maintenance of the extracellular matrix in connective tissue.

15. Which of the following statements pertains to hyaline cartilage?

Highly vascular

Surrounded by perichondrium except at articular surfaces

Contains matrix composed primarily of glycoproteins

Contains type 1 collagen

Capable of extensive turnover and repair

Hyaline cartilage is surrounded by perichondrium, which is a dense connective tissue, except at the articular surfaces. The perichondrium provides nutrients and oxygen to the cartilage cells and helps in their repair and maintenance. The absence of perichondrium at the articular surfaces allows for smooth movement and reduces friction between bones.

18. When cartilage is damaged it is replaced by___________.

More cartilage

Dense conective tissue

Reticular conective tissue

Hyaline connective tissue

When cartilage is damaged, it is replaced by dense connective tissue. This is because dense connective tissue has a higher density of collagen fibers, which provide strength and support to the damaged area. This type of tissue is able to withstand more mechanical stress and is better suited for repairing and replacing damaged cartilage.

22. Which of the following types of cells is shown above?

Mast Cells

Plasma Cells

Fibroblasts

Microphages

The correct answer is Plasma Cells. This is because the image shown above represents cells that have a distinct appearance with a large, eccentric nucleus and a perinuclear clearing. These characteristics are typical of plasma cells, which are a type of white blood cell involved in immune responses. Mast cells, fibroblasts, and microphages do not have the same morphological features as plasma cells, making them incorrect options.
