What is lacunae in cartilage?

In growing cartilage, the chondrocytes can divide, and the daughter cells remain close together in groups, forming a ‘nest’ of 2-4 cells. The matrix enclosed compartments that they sit in are called lacunae. (lacunae = little lakes/small pits).

What is found in the lacunae of hyaline cartilage?

Hyaline cartilage is the most common type of cartilage. Find the surrounding capsule-like perichondrium . The chondrocytes , shrunken with tissue preparation, are located within lacunae . The area immediately adjacent to the cell is called the capsule and stains intensely because of the rich glycosaminoglycan content.

What is the function of lacunae in hyaline cartilage?

Chondrocytes are found in lacunae, which are small cavities that surround the chondrocytes. A primary lacuna is a lacuna containing one chondrocyte. When that cell divides, the daughter cells form new boundary layers called secondary lacunae, and the group of cells with lacunae is called a cell nest.

Are there lacunae in cartilage?

Cartilage is a flexible connective tissue that differs from bone in several ways. For one, the primary cell types are chondrocytes as opposed to osteocytes. They lie in spaces called lacunae with up to eight chondrocytes located in each.

What are the characteristics of hyaline cartilage?

Hyaline cartilage is pearl-grey in color, with a firm consistency and has a considerable amount of collagen. It contains no nerves or blood vessels, and its structure is relatively simple.

What kind of cells are found in hyaline cartilage?

Lacunae are the oval or elliptical space like cavity in the matrix of hyaline cartilage. Some lacunae contain only one chondrocyte, and some others include two, three or four chondrocytes. These type of multicellular lacunae are also known as cell nest or isogenous cells groups. Matrix of hyaline structure

How many cells are in a lacuna of cartilage?

Each lacuna is usually occupied by a single cell, but during mitosis, it may contain two, four, or even eight cells. Histology of articular cartilage zones.

How are lacunae formed in the human body?

These cavities are actually artificial gaps formed from the shrinking of the cells during the staining and setting of the tissue for examination. The inter-territorial space between the isogenous cell groups contains relatively more collagen fibres, allowing it to maintain its shape while the actual cells shrink, creating the lacunae.

What is the function of hyaline cartilage in the trachea?

It is surrounded by a membrane called the perichondrium, which provides nutrients to the cartilage since the cartilage tissue has no blood vessels of its own. This is an image of hyaline cartilage in the trachea viewed through a microscope at 400x magnification.
