In connective tissue proper the extracellular matrix is soft; in cartilage it is much firmer, partially calcified, but flexible in nature; and in bone the matrix is rigid because of the presence of calcium salts, which are in the form of hydroxyapatite crystals. Cartilage and bone are ...
For example, if part of a blood vessel or a peripheral nerve is isolated from the body, it will shorten by almost 25% from its original length. When an individual is growing, the tensions produced by the elongating skeleton stimulate the fibroblasts in connective tissue to produce more ...
The remains of ovarian follicles reported in nine specimens of basal birds represents one of the most remarkable examples of soft-tissue preservation in the Early Cretaceous Jehol Biota. This discovery was immediately contested and the structures alternatively interpreted as ingested seeds. Fragments of ...
At present, the model/structure of the combination of TNTs and CX43-based GJCs in intercellular communication is still ambiguous and not uniformly described in different studies. For example, some TNTs are open-ended, some are closed, and some are closed at one end. In general, the closed...
The hip joint is an example of aball and socketsynovial joint. This joint is called a ball and socket joint, because the head of the femur (which is... Learn more about this topic: Ball & Socket Joint | Movement, Examples & Function ...
As an alternative to the immune-mediated cause of MS, it has been postulated that CNS-intrinsic events (for example, CNS viral infection or processes leading to primary neurodegeneration) may trigger disease development, with the infiltration of autoreactive lymphocytes occurring as a secondary phenome...
Having reviewed the nuclear stains, let’s talk about the cytoplasmic component dyes. Eosin is the most commonly used counterstain that distinguishes between the cytoplasm and nuclei of cells. It is typically pink, with different shades of pink for different types of connective tissue fibers....

For example, a study from Haemmerich et al. showed that at 1 MHz, the electrical conductivity of hepatic tumors was 15% higher than the one of healthy tissue (5.23±0.82 S.m−1 vs 4.61±0.42 S.m−1) [5]. According to the authors, the probable reason of this change is the ...
This feature makes bottom-up engineering attractive as a versatile method for incorporating multiple cell types into tissues as well as for building different tissue types or states (for example, functional or pathological) by interchanging building blocks. Furthermore, these methods are inherently ...
