What does N&M mean in PHYSIOLOGY

Nerves are part of the central nervous system which consists of neurons that send electrical signals throughout the body. These signals tell different parts of the body what to do and how to respond to stimuli both internal and external.

Muscles are organs that contract when stimulated by nerve impulses sent from the brain or spinal cord. Unlike nerves, muscles can contract voluntarily - meaning we can decide to move our arms, legs, etc. Muscle contraction is also responsible for vital functions such as breathing and digestion.

Homeostasis is a state of equilibrium where internal physiological conditions remain constant despite fluctuations in external environment conditions. It is maintained through feedback systems provided by nerves and muscles which detect changes in temperature, pH levels, water content and sends messages back to various tissues which then adjust accordingly so that homeostasis is always preserved.

Nerves provide communication between different parts of the body by sending electrical signals while muscles provide movement by contracting when stimulated by these same signals. This interaction between nerves and muscles allows us to control voluntary movements like walking or running but also involuntary movements like breathing or heart rate regulation.

If something goes wrong with this system then it could have serious consequences on your health as it could affect muscle strength, coordination, balance or cause paralysis if left untreated for too long. That's why it's important to get any symptoms related to nerve or muscle disorders checked out immediately by a doctor or specialist as soon as possible so they can be treated if necessary.
