What are glial cells? What are giant cells that destroy bone? What kind of cells compose bone tissue? Are bone marrow stem cells pluripotent? How are stem cells used in bone marrow transplants? What forms at each week of embryonic development?
What are glial cells? What type of electrodes used to electrically stimulate the brain? How do axons and dendrites work together in the brain? What is the function of a gap junction between neurons? What is a myelin sheath? What is the difference between afferent and efferent neurons?
The brain is composed of billions of cells that use chemicals and electricity to communicate between themselves and the rest of the body. There are two major types of cells, neurons and glial cells; there are subtypes of these cells. Neurons Neurons are the cells that process and transmit inf...

Examples arevimentin (mesenchyme), glial fibrillary acidic protein (glial cells), neurofilament proteins (neuronal processes), keratins (epithelial cells), and nuclear lamins. Which cells have a glycocalyx? The glycocalyx, which is atopthe epithelial cells, is a fuzzy and filamentous coat that is ...
The myelin from which the nerve sheath is formed consists primarily of fat, although it also contains some protein. Myelin is manufactured by structures known as glial cells, which support the formation and function of the neurons. It is the pale color of the myelin that gives certain organs,...
While this is surprising if one takes the view that high circulating cholesterol will result in high neuronal cholesterol, it is predictable if one considers that ApoE4-derived glial cells have low ability to release cholesterol [33]. As described earlier, mature neurons are dependent on the ...
The nucleolus is a dense structure in the nucleus composed of proteins and RNA. This is the site where RNA is synthesized and ribosomes are created. Ribosomes will then be moved out of the nucleus into thecytosolof the cell, where they play a key role in protein synthesis by translating ...
It comprises two types of cells, nerve cells (neuron) and glial cells. 3. Organ Level Organisation: Two or more tissues are organised to form specific organs that are designed and adapted according to their functions. A few examples are as follows: I. The stomach is a sac-like organ ...
There are several examples of a role for p53 in blocking the reinitiation of a second S-phase in cells that can not enter cytokinesis because of treatments with spindle poisons.59This is one of the ways in which p53 prevents karyotypic instability in cells, which is a major function or out...
