- Systemic anatomy- structure of specific systems of the body such as the nervous system or respiratory system
Subspecialties of Physiology
- Neurophysiology- functional properties of nerve cells
- Endocrinology- hormones and how they control body functions

In our body, we have connective tissues whose main function is to bind, support, and anchor the body. The structural element that allows it to do so is the ground substance (a clear fluid that fills the space between the cells and fiber.) It acts as a glue that fills the spaces between fibres and cells.
