While a bone is a solid structure, a joint is, in a way, a nonstructure.

Elastic cartilage has many elastic fibers in addition to collagen, making the matrix much more elastic than hyaline cartilage. Elastic cartilage provides support but can tolerate deformation without damage and can return to its original shape. It is found in the external ear, epiglottis, and larynx (voice box).

Osteoporosis (coming from Greek for porous bone) is a skeletal disorder characterized by low bone mass density making bones more susceptible to fracture or breaking.

Cohort Study. Two groups (or cohorts) of participants, one which has received the exposure of interest and one which has not, are followed for the outcome of interest.

In addition to the external force provided by gravity, the internal force provided by muscular contraction can also provide enough stimulus to elicit bone adaptation.

There are three types of muscle: cardiac, smooth, and skeletal. Cardiac muscle forms the walls of the heart, pumping blood every minute of every day. Smooth muscle is found in a variety of areas and serves functions such as contracting the arteries to control blood pressure, raising the small hairs on your arm, and moving fluids through organs by

Because we can bear greater loads eccentrically than we can concentrically, eccentric training can enhance maximal muscle strength and power even faster than solely concentric training. Plus, it can further optimize maximal tension at a greater degree of extension (Vogt and Hoppeler 2014).

A physiological principle that should be taught in every yoga teacher training (and arguably to every human in the world) is that our bodies have an inherent and profound ability to adapt.

Randomized Controlled Trials. These are studies with a randomized group of participants in an experimental group and a control group. These groups are followed up for the variables or outcomes of interest. Control groups often take a placebo to give the analysis a comparison point.
