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.

What happens to the intraalveolar pressure when the diaphragm contracts?
It decreases, and air goes into the lung passages. You inhale.
What are the three kinds of skeletal cartilage?
Hyaline cartilage Elastic cartilage Fibrocartilage
What type of cartilage has the fewest fibers?
hyaline cartilage
How does the structure of hyaline cartilage follow its function?
didn't see the answer
What kind of tissue is the cartilage of your nose made of?
Hyaline cartilage.
Membrane bones develop from hyaline cartilage structures?
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.
Respiratory in a newborn?
hyaline membrane disease
Do membrane bones develop from hyaline cartilage structures?
Yes
What is another term for respiratory distress syndrome?
hyaline membrane disease
What was the treatment for hyaline membrane disease in 1974?
introduction of surfactin. (synthesized cow growth hormone)
What infant disease is also called hyaline membrane disease?
infanet respiratory distress syndrome
How is purkinje cells affected by hyaline membrane disease?
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 the correct answer to this description of connective tissue.
What happens to the intraalveolar pressure when the diaphragm contracts?
It decreases, and air goes into the lung passages. You inhale.
What is The most abundant skeletal cartilage type is?
Hyaline cartilage is the most common, abundant type of cartilage found in the body.
