Hyaline cartilage does not have

The correct option is "fibers".

Hyaline cartilage is the most common type of cartilage in the human body, found in areas such as the nose, trachea, bronchi, and the articulating surfaces of joints. To understand why it lacks visible fibers, let us break down the components of cartilage tissue and look at the structure of hyaline cartilage:

1. Cells (Chondrocytes):
Like all cartilage types, hyaline cartilage contains specialized cells called chondrocytes. These cells are responsible for producing and maintaining the cartilage matrix.

2. Lacunae:
Chondrocytes are located within small cavities or spaces in the extracellular matrix. These cavities are called lacunae. Therefore, lacunae are definitely present in hyaline cartilage.

3. Blood Capillaries:
While cartilage in general is avascular (lacking direct blood supply), the key distinguishing histochemical feature of hyaline cartilage under standard light microscopy is its glassy, homogeneous appearance, which is due to the absence of visible fibers.

4. Fibers (Why it is the correct choice):
Although hyaline cartilage contains collagen (primarily Type II collagen) to provide structural support, these collagen fibrils are extremely fine and have a refractive index very similar to the ground substance (chondroitin sulfate matrix) in which they are embedded. As a result, these fibers cannot be resolved or visualized as distinct, discrete fibers under a standard light microscope, giving the matrix a smooth, glassy ("hyaline" comes from the Greek word hyalos, meaning glass) appearance. Unlike elastic cartilage (which has visible elastic fibers) or fibrocartilage (which contains dense, prominent bundles of Type I collagen fibers), hyaline cartilage does not have visible, distinct fibers in its matrix.
