The lamellae are the concentric circles around the Haversian canal; they are a bone matrix formed from calcium, phosphorus salts and fibres.The lacunae are small spaces in the lamellaewhich provide an area for bone cells or osteocytes. This is the key difference between lamellae and lacunae. Wh...

Muscle is the fibrous tissue in the body that has the ability to contract (when asked to do so by the brain). When a muscle contracts, it shortens (becomes smaller). Muscles are attached to the bones of our skeleton (through strong fibres called tendons). So, when the muscle attached t...

factor. There are four types of fibres,each type concerned with a different sort of pattern. Eachtype is uniformly distributed over the whole retina of thefrog. Thus, there are four distinct parallel distributed chan-nels whereby the frog's eye informs his brain about the visualimage in ...
Another study reported that the exposure to polystyrene microplastics is able to cause a thinning of the endometrium and severe deposition of collagen fibres in female mice, finally leading to uterine fibrosis .[17] [Luo et al., 2019 (10.1021/acs.est.9b03191)] All these works are inevitably...

Interestingly, there are many histone variants, which can result in nucleosomes with versatile structures and functions [6,7]. Nucleosome particles are connected by linker DNA of varying lengths (~20–80 bp; ~6.6–27 nm), creating repetitive motifs of ~200 bp units, called ‘beads on a ...
