The affix -blast means an immature cell, and -cyte indicates any cell. So how do we define if a cell is mature (-cyte) or immature (-blast)? How does this apply to odontoblasts and ameloblasts? Why...
Myocyte - [cyte:cell] they are already differentiated, hence are fully specific about themselves what constituent they are going to become. Myotubes - myocytes condense as a mass, also besides that they undergo elongation as well, which ultimately results into formation of bundle like structure.
Sexes (male and female) are generally defined in terms of Anisogamy, which means that there are size differences between the gametes (i.e. the reproductive cells that fuse at fertilization). The sex with smaller gametes is defined as male and the sex with larger gametes is defined as female, and individuals that can produce both types of gametes are called hermaphrodites. This is the case in ...
The osteoblast, now encased in a shell of hydroxyapatite (called the lacuna), transforms into an osteocyte (-cyte = mature cell) and projects long arm-like structures called filopodia which it uses as sensors and to communicate with surrounding osteocytes.
The vessel diameter is the most principal determinant to control resistance. Compared to other smaller vessels in the body, the artery has a much bigger diameter (4 mm), therefore the resistance is low. In addition, flow rate (Q) is also the product of the cross-sectional area of the vessel and the average velocity (Q=AV). Flow rate is directly proportional to the pressure drop in a tube or in ...
