GENERAL HISTOLOGY

Detailed explanation-1: -In osteonecrosis, blood flow to part of a bone is disrupted. This results in death of bone tissue, and the bone can eventually break down and the joint will collapse. Osteonecrosis is also called: Avascular necrosis.

Detailed explanation-2: -Avascular necrosis is the death of bone tissue due to a lack of blood supply. Also called osteonecrosis, it can lead to tiny breaks in the bone and cause the bone to collapse. The process usually takes months to years.

Detailed explanation-3: -What is Avascular Tissue? Tissues that do not contain blood vessels or lymphatic system are referred to as avascular tissues. Examples of avascular tissue include epithelial cells, cornea of the eye and cartilage.

Detailed explanation-4: -Epithelial and connective tissue are generally avascular, which means they lack a blood supply. While, Muscle and nervous tissue are vascular tissues, which means they have a strong blood supply.

Detailed explanation-5: -Cartilage is an avascular, supporting and articular skeletal tissue consisting of cells in an extracellular matrix that may or may not mineralise depending on cartilage type, species or group of organisms; many invertebrates have cartilage but it never mineralises.
