Crocodilian form of crurotarsal ankle. The astragalus (pink) is fixed to the tibia (green) by a suture. Adapted with permission from Palaeos. In the type of crurotarsal ankle, which is found in crocodilians and some other archosaurs, the astragalus is fixed to the tibia by a suture, and the joint bends around a peg on the astragalus, which fits into a socket in the calcaneum.
Fibroblasts, the main cells that deposit granulation tissue, depend on oxygen to proliferate and lay down the new extracellular matrix. [7] In vascularisation, also called angiogenesis, endothelial cells quickly grow into the tissue from older, intact blood vessels. [8] These branch out in a systematic way, forming anastomoses with other vessels.
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and size as well as thread material ...
A suture is a type of fibrous joint that is only found in the skull (cranial suture). The bones are bound together by Sharpey's fibres . A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull.
The endothelium is a thin layer of single flat cells that line the interior surface of blood vessels and lymphatic vessels. [1] Endothelium is of mesodermal origin. Both blood and lymphatic capillaries are composed of a single layer of endothelial cells called a monolayer. In straight sections of a blood vessel, vascular endothelial cells ...
The actual suture between the bridge and the plastron is called the anterior bridge strut. [4] In Pleurodires the posterior pelvis is also part of the carapace, fully fused with it. This is not the case in Cryptodires which have a floating pelvis. [2] [3] The anterior bridge strut and posterior bridge strut are part of the plastron. On the ...
Having smooth scene changes would have meant they had to fuse parts together in unique ways to keep the changes from being jarring, but jarring changes were often part of the point. They liked abrupt.
Histology of a synovial membrane. H&E stain. The synovial membrane is variable but often has two layers: [4] The outer layer, or subintima, can be of almost any type of connective tissue – fibrous (dense collagenous type), adipose (fatty; e.g. in intra-articular fat pads) or areolar (loose collagenous type).
