A pathological condition characterized by the combination of fibrin and cellular debris, found inside the alveolar sacks of the lungs. They are the result of leakage of blood components into the alveolar sacks. They inhibit gas exhange and result in systemic hypoxia, with possible death in premature babies and symptoms of acute respiratory distress syndrome in adults.
For example, neonatal respiratory distress syndrome features intra-alveolar hyaline membranes. This disease occurs in premature births. The newborn has not produced sufficient surfactant and so most of the alveoli in his/her lungs collapse. The few remaining alveoli are given the entire blood supply of the lung. Overloading of the blood vessels causes high hydrostatic pressure and eventual leakage of blood components into the alveoli supplied by the blood vessel. As these components accumulate, intra-alveolar hyaline membranes start to form. The membranes hinder the gas-exchange that would normally take place in the alveoli, leading to systemic hypoxia. This is the most common cause of death in premature babies.
When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity. This leads to a decrease in intraalveolar pressure, causing air to flow in from the atmosphere to equalize the pressure, resulting in inhalation.
The cartilage of the nose is made of hyaline cartilage, which is a type of connective tissue. Hyaline cartilage is strong yet flexible, providing structure and support to the nose.
The three types of skeletal cartilage are hyaline cartilage, elastic cartilage, and fibrocartilage. Hyaline cartilage is the most abundant type and provides support with flexibility. Elastic cartilage contains elastic fibers, allowing for greater flexibility. Fibrocartilage is the strongest type, providing both support and cushioning.
Hyaline cartilage provides support and smooth surfaces for joint movement. It allows flexibility and reduces friction between bones in joints.
didn't see the answer
It would be false to say membrane bones develop from hyaline cartilage structures. It is cartilage, rather than membrane bones, that comes from hyaline cartilage structures.
hyaline membrane disease
No, membrane bones do not develop from hyaline cartilage structures. Membrane bones are formed directly from mesenchyme tissue through intramembranous ossification, while hyaline cartilage serves as a precursor for endochondral ossification, where bones are formed by replacing cartilage with bone tissue.

I was born with hyaline membrane disease and later in life I was diagnosed with asperger disease (on the autism spectrum). I am not a medical doctor of any kind, but would like to share what I found so far. I found an article in ACTA Neuropathologica called "Lesions of the Brain in Hyaline Membrane Disease of infants." In very basic terms, brain autopsy on infants that died of hyaline membrane were performed and the results were compared to brain autopsy of infants that did not observe having hyaline membrane, but died due to other issues. They found that the infants born with and died from hyaline membrane observed to have either never developed purkinje cells normally in prenatal life or the purkinje cells underwent rapid cellular disintergration in utero. The purkinjie cells were less densely packed in the cerebellum and/or less mature formation of the purkinje cells. On a side note, in another article, brain autopsy were performed on people who died and were diagnosed with autism when alive. The ages span from very young and older. The findings show the same purkinje formations and immaturied of the cells in autism people as find in the hayline membrane diesase.

Hyaline cartilage is found on the joint surfaces.

Hyaline cartilage is the tissue that fits this description. It has a firm matrix invaded by collagen fibers, giving it a glassy and smooth appearance. It is commonly found in joints, the respiratory system, and the developing skeleton.
