Myelin staining are selectively dyes the sheaths of Myelinated axons. As a result, white matter, which consists of myelinated axons, stains black, unlike other areas of the brain that consist mostly of cell bodies and nuclei.

Myelinated axon is axon covered with a Myelin sheath

Myelination is defined as development of a Myelin sheath that insulates an axon; development of myelin around neurons, which proceeds at different rates in different areas of the brain.

Myelinization refers to the process by which neurons are enclosed in waxy Myelin sheaths that will facilitate the transmission of neural impulses.

Myers-Briggs Type Indicator is defined as an instrument for measuring a person’s preferences, using four (4) basic scales with opposite poles. The four (4) scales are: (1) extraversion/introversion, (2) sensate/intuitive, (3) thinking/feeling, and (4) judging/perceiving.

Myocardial infarction refers to death of a portion of heart tissue that no longer conducts electrical activity nor provides force to move blood. Please see also MI. Myocardial infarction is also known as Angina pectoris or Cardiac arrest. Chest pain is a common symptom.

Myocardial ischemia is defined as a condition in which the myocardium experiences an inadequate blood flow; sometimes accompanied by irregularities in the electrocardiogram (Arrhythmias and ST-segment depression) and chest pain (Angina pectoris).

Myocardium is the cardiac or heart muscle that provides the force of contraction to eject blood; muscle type with many mitochondria that is dependent on a constant supply of oxygen.
