What is a lacuna and what is its function?

The main function of a gap in bone or cartilage is to accommodate the cells it contains and to keep the trapped cells alive and functional. In bones, lacunae enclose osteocytes, in cartilage, lacunae enclose chondrocytes. 1

What are the shortcomings?

1: a space or a missing part: gap also: gap. 2: Small cavity, pit, or discontinuity in an anatomical structure. Examples: The osteocyte is an isolated cell in a bone gap.

where is the gap

Osteocyte, a cell found in the substance of a fully formed bone. It occupies a small chamber called the lacuna, contained within the calcified matrix of bone.

What is a gap quizlet?

Gap. a small cavity or depression in tissue. slats.

How do gaps arise?

Gaps arise as a result of tissue shrinkage and cutting artifacts, while cell death often involves infiltration of defensive cells (for elimination), increased compensatory proliferation of neighboring cells, changes in cell morphology, and the presence of cellular debris, resulting in increased tissue congestion.. .

What is a gap in anatomy?

Void in anatomy Void (biological definition): (histology) the small cavity containing an osteocyte in bone or a chondrocyte in cartilage (botany) an air space in plant tissue (general) a small depression, void, or cavity. 1

What are gaps and what are they used for?

Gap. a cavity or depression, such as one of the many small spaces between bone lamellae, that is occupied by individual bone cells. Small canals (canaliculi) radiate from the lacunae, and within these are small protoplasmic processes that connect to osteoblasts in other lacunae.

What is a gap quizlet?

Gaps. Tiny cavities in the bone matrix where osteocytes reside. foramen. A round or oval opening in a bone. Tuberculosis.

What is a cartilage gap?

In the growing cartilage, the chondrocytes are able to divide and the daughter cells stay in clusters close together, forming a 24-cell nest. The compartments enclosed in the matrix in which they reside are called vacancies. (gaps = small lakes/small ponds).

Where are the gaps to be found?

Compact Bone Between the rings of the matrix are bone cells (osteocytes) in spaces called lacunae.

Where is the gap in an osteon?

Lacunae are the hollow chambers that house osteocytes in an osteon. These lacunae are scattered around the central canal found in the lamella (calcified extracellular matrix).

What are the gaps and what do we find there?

a cavity or depression, such as one of the many small spaces between bone lamellae, that is occupied by individual bone cells. Small canals (canaliculi) radiate from the lacunae, and within these are small protoplasmic processes that connect to osteoblasts in other lacunae.

Is there a gap in the connective tissue?

There are three types of cartilage: hyaline, elastic, and fibrocartilage. All three are made up of collagen fibers, but they differ greatly in the amount of elastic fibers present in the tissues. The tissues characteristically have spaces or chambers called lacunae (pl.)

What is a Canaliculus Quizlet?

Periosteum (Definition) The periosteum is a membrane covering the outer surface of all bones except at the level of the joints of long bones. Canaliculi (definition) Canaliculi are microscopically small canals between lacunae of ossified bone, they serve to connect the Haversian canals inside the bone.

What is the structure of the Bone Gap Quizlet?

Osteocytes are located in chambers called lacunae.

What’s trapped in the gaps?

The lamellae of the Haversian system are formed by osteoblasts. As these cells secrete the matrix, they become trapped in spaces called lacunae and become osteocytes. Osteocytes communicate with the Haversian duct through cytoplasmic extensions that pass through canaliculi, small interconnected canals.

What’s in the gap quizlet?

the primary cell of mature bone and the most common type of bone cell. Each osteocyte is located in a space called a lacuna and is surrounded by bone tissue.
