epigenetics – The study of chemical factors involved in gene expression, that produce both differences in cell types within an organism (somatic epigenetics), as well as heritable changes not caused by DNA mutations (germline epigenetics).
axial skeleton – the portion of the skeleton that supports and protects the head, neck, and trunk
The mechаnicаl fоrce оf cоntrаction is generated by:
