Small, constant adjustments of the skeletal muscles are needed to hold a body upright or balanced in any position. Muscles also prevent excess movement of the bones and joints, maintaining skeletal stability and preventing skeletal structure damage or deformation. Joints can become misaligned or dislocated entirely; muscles work to keep joints stable.

EPSPs bring the potential closer to action potential threshold while IPSPs push it away. Summation integrates these potentials spatially and temporally.

The electrical change that is carried down the axon is called an action potential. In electrical synapses, the action potential can be carried from one neuron to another through gap junctions. In chemical synapses, the action potential can be converted into chemical signals called neurotransmitters.

A deficiency can lead to scurvy, causing various health issues. Ascorbic acid also functions as an antioxidant and improves iron absorption. While it may offer protective benefits against cardiovascular disease and cancer, more research is necessary to confirm these associations.

The main signaling molecules of the ANS are acetylcholine, norepinephrine and epinephrine. The axons of the two divisions differ in the released neurotransmitters. Most organs are dually innervated and display autonomic tone. Autonomic reflexes are similar to somatic ones in their afferent branch but not efferent one. Autonomic reflexes can be long if they pass by the CNS or short if they don't.

It explains muscle structure, contraction mechanics via myosin-actin interaction, calcium's role, and ATP's importance in energy supply. Muscle fatigue, types of contractions (isotonic and isometric), and mechanisms like wave summation and tetanus are discussed.
