Cartilage. The cartilage cells or chondrocytes are contained in cavities in the matrix, called cartilage lacunae; around these, the matrix is arranged in concentric lines as if it had been formed in successive portions around the cartilage cells.

What cells live in the lacuna?
Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
What kind of cells do you find in the lacunae of cartilage?
The cells of cartilage, called chondrocytes, are isolated in small lacunae within the matrix.
Why do cells in cartilage have to live in the lacuna?
They lie in spaces called lacunae with up to eight chondrocytes located in each. Chondrocytes rely on diffusion to obtain nutrients as, unlike bone, cartilage is avascular, meaning there are no vessels to carry blood to cartilage tissue. This lack of blood supply causes cartilage to heal very slowly compared with bone.
Which of the following can be found in lacunae?
Osteocytes are found within lacunae. Giant multinucleated osteoclasts, which break down bone, are occasionally found in lacunae termed Howship's lacunae. These are readily found in the ossification zone of the growth plate.
What is a lacuna in cartilage?
Anatomical terminology. In histology, a lacuna is a small space, containing an osteocyte in bone, or chondrocyte in cartilage.
What is a lacuna in anatomy?
lacuna \luh-KOO-nuh\ noun. 1 : a blank space or a missing part : gap; also : deficiency. 2 : a small cavity, pit, or discontinuity in an anatomical structure. Examples: The osteocyte is a cell that is isolated in a lacuna of bone.
What is a cartilage cell that has become enclosed in a lacuna called?
a cartilage that has become enclosed in lacuna in the cartilage matrix is called the. chondrocyte.
How is lacuna in plant cells formed?
In other instances we find large air cavities, as in the stems of Grasses and Umbelliferous plants, which have been formed by the destruction of their internal tissues by the more rapid growth of the outer portions; these large cavities are termed lacunae, and appear to have no special functions to perform.
What cells are in elastic cartilage?
Cartilage is made up of specialised cartilage cells called chondrocytes. In elastic cartilage, they are organised into elastic fibers, which make up a threadlike network or matrix. This matrix is composed of glycosaminoglycans, proteoglycans and multiadhesive glycoproteins.
How does the central canal differ from a lacuna?
how does the central canal differ from a lacuna in terms of location and the material found in each respective space? the central canal houses blood vessels and nerves in the dense bone tissue. lacuna are around the central canal and bone cells (osteocytes) occupy in living space.
Where are chondrocytes and osteocytes located lacuna?
Chondrocytes are located in the cartilage of the body and osteocytes are located in the bone. Chondrocytes reside in tiny pockets called lacunae that...
How is the lacuna different from the Canaliculus?
The lacuna houses the osteocyte, while the canaliculus houses the cytoplasmic extension of the osteocyte.
Why do cells in cartilage have to live in a lacuna quizlet?
1. Chondrocytes housed in lacunae undergo mitotic cell division. ... As the cells begin to synthesize and secrete new cartilage matrix, they are pushed apart and now reside in their own lacunae.
How does cartilage tissue receive nutrients?
Cartilage cells, called chondrocytes, occur at scattered sites through the cartilage and receive nutrition by diffusion through the gel; cartilage contains no blood vessels or nerves, unlike bone.
What is fibro cartilage?
Fibrocartilage is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes.
