Explanation / Answer

Answer

During muscle Relaxation, the distance between the Z-discs increases due to the relative sliding of filaments, and the adjacent A bands become thickened

Our circadian rhythms are entrained to light-dark cycles through connections between the hypothalamus and tracts from our retinas.

The neurotransmitter used in synapses of all pre-ganglionic axons is acetylcholine.
