Does Fibrosis occur when adipocytes divide to form new connective tissue during tissue repair?
Fibrosis is a pathological process characterized by the excessive accumulation of extracellular matrix components, primarily collagen, leading to scarring and tissue stiffening. While adipocytes (fat cells) can proliferate and play a role in tissue repair, fibrosis specifically refers to the formation of fibrous connective tissue, not the normal division of adipocytes. In some cases, when tissue is damaged, an imbalance between repair and degradation can lead to fibrosis, but this is distinct from the normal regenerative processes involving adipocytes.

Is it true during fibrosis fibroblasts in the granulation tissue lays down keratin fibers?
No, fibroblasts lay down collagen fibers during fibrosis, not keratin fibers. Keratin is a protein that is typically found in skin, hair, and nails, while collagen is a major component of the extracellular matrix. Fibroblasts produce collagen to help repair and replace damaged tissue during the process of fibrosis.
What type of connective tissue allows lung to expand and recoil?
Elastic connective tissue is responsible for allowing the lung to expand during inhalation and recoil during exhalation. It provides the necessary elasticity to maintain the shape and function of the lung during breathing.
What is connective tissue of the skin developed from?
Connective tissue of the skin is primarily derived from the mesoderm layer of the embryonic germ cells during development. Mesoderm cells differentiate into fibroblasts that produce collagen and elastin fibers, which are essential components of connective tissue in the skin.
How is fat mobilized from adipocytes?
When the body needs to mobilize fat for energy, hormone-sensitive lipase is activated in adipocytes to break down triglycerides into fatty acids and glycerol. These fatty acids are released into the bloodstream to be taken up by other tissues, such as muscle cells, where they can be used for energy production.
What are immature connective tissue?
Immature connective tissue refers to newly formed and developing connective tissue that has not fully matured or undergone complete differentiation. It is characterized by a higher proportion of cells and ground substance compared to mature connective tissue, and is often present during the early stages of wound healing or tissue repair. Over time, immature connective tissue typically undergoes remodeling and maturation to acquire the characteristic properties of the specific type of connective tissue.
Why do your lungs shrink when you have sclerdoma?
In scleroderma, the immune system mistakenly attacks the body’s connective tissues, leading to fibrosis or thickening of these tissues. When this occurs in the lungs, it can cause scarring and stiffness, reducing lung capacity and making it difficult to expand fully during breathing. This fibrosis can impair gas exchange, leading to symptoms such as shortness of breath and reduced overall lung function.
What type of connective tissue prevents muscles from pulling away from the bones during contraction?
Dense connective tissue - it makes up the tendons.
Why is blood connective tissue?
Blood is a connective tissue because it connect through the body ,and also have fibers that are visible during blood clotting.
Is it true during fibrosis fibroblasts in the granulation tissue lays down keratin fibers?
No, fibroblasts lay down collagen fibers during fibrosis, not keratin fibers. Keratin is a protein that is typically found in skin, hair, and nails, while collagen is a major component of the extracellular matrix. Fibroblasts produce collagen to help repair and replace damaged tissue during the process of fibrosis.
Why is blood a connective tissue?
Yes blood is a connective tissue .Connective tissue is one which is rich in intercellular substance or interlacing processes with little tendency for the cells to come together in sheets or masses.
What type of connective tissue allows lung to expand and recoil?
Elastic connective tissue is responsible for allowing the lung to expand during inhalation and recoil during exhalation. It provides the necessary elasticity to maintain the shape and function of the lung during breathing.
What is connective tissue of the skin developed from?
Connective tissue of the skin is primarily derived from the mesoderm layer of the embryonic germ cells during development. Mesoderm cells differentiate into fibroblasts that produce collagen and elastin fibers, which are essential components of connective tissue in the skin.
Flexible connective tissue that is replaced by bone during ossification?
Cartilage is the flexible connective tissue that is gradually replaced by bone during the process of ossification. This transformation allows for the growth and development of long bones in the body.
How is fat mobilized from adipocytes?
When the body needs to mobilize fat for energy, hormone-sensitive lipase is activated in adipocytes to break down triglycerides into fatty acids and glycerol. These fatty acids are released into the bloodstream to be taken up by other tissues, such as muscle cells, where they can be used for energy production.
During meiosis sex cells divide to form?
during meiosis, sexcells divide to form?
What breaks down connective tissue and tenderizes meat during cooking?
Msg(monosodiumglutamate)
When to do amniocentesis for cystic fibrosis?
Amniocentesis for cystic fibrosis is typically performed during the second trimester, usually between 15 and 20 weeks of gestation. It is recommended for pregnant women who are carriers of the cystic fibrosis gene or when there is a family history of the condition. The procedure involves extracting amniotic fluid to test for mutations in the CFTR gene, allowing for early detection of cystic fibrosis in the fetus. Counseling and informed consent are essential before proceeding with the test.
