Difference between muscular and normal force

[incursio52]

TL;DR Summary

I am so much confused between normal and muscular force . The question I want to ask is that if I push or pull a body the force I am applying on the body is muscular force or normal force between my hand and block surface of contact??


OR, should I say that there is only muscular force acting between my hand and block surface??

Also ,according to my book it states that whenever there is a contact between two bodies there exists a contact force which is =√N²+f².

Please anyone help.

The muscles act internally. They don't affect the external physics directly, but are part of the internal biomechanics of your body.
