Bones are active organs. Aside from their role in providing structural support, they help to permit movement, allow muscles to contract, protect organs, serve as a factory for the production of blood cells, and help to regulate homeostasis. The compact hard outer layer of bone, as well as its cancellous (spongy inner) layers, give it structure and strength. The delicate balance between osteoblasts (bone-forming cells) and osteoclasts, which break down bone, is responsible for maintaining bone tissue.
Super helpful introduction and outline of future lectures. I appreciate the integrated instructions surrounding structure, location, function, and particular roles within the body. These lectures are helpful supplements to textbook readings.
While this was certainly a helpful lecture with breaking down differences between mature versus immature bone, not revealing the labeled diagram could prove detrimental to student learning. I noticed when quizzing myself that stronger learning might be taking place, but ultimately, I am not sure if everyone myself included could fully and adequately label every structure on this histological slide. Could you provide these diagrams with labels if they are not already somewhere? My histology atlas displays images differently.
Explanation excellent, diagrams excellent ????. However, the use of a pointer would be beneficial
The lecture on bone formation is not comprehensive and not very easy to digest The photos given by the lecturer is not very good in terms of illustrating the main concepts Having said all these, I recognise that making such lecture series is no easy task and the efforts put in by all staffs are commendable
