The Action Potential Scheme

This topic pops up a lot when talking about the nervous system. It is this action potential that allows us to have any sort of feelings in our senses! No kiddin’. So, I hope this will help it stick in your mind!

Our neurons work by an all or nothing method. This means, the action potential is either relaying info to and from your central to your peripheral nervous system and vice versa. In other words, you touch a hot stove, the hotness stimulates your peripheral nervous system which sends a signal to your brain (central nervous system), which gets your neurons to send out a signal to other nearby neurons to eventually get to the part of the brain Read on…

Microscopic Structure of the Skeletal System: What makes our bones Strong?

We have previously discussed the structure of our bone macroscopically, and we have discussed how strong compact bones are compared to cartilage bones. However, we have yet to delve into why our bones are strong. Hence, this post is focused on further explaining the bone matrix, how bones are formed, and the concept of bone remodeling or resorption.

Macroscopic Structure of the Skeletal System

The overall function of the musculoskeletal system is simply to provided us with movements and structure of our form. In this post we will focus on the skeletal system covering the macroscopic and microscopic bone structure, bone formation, and bone remodeling.
