Myelin sheath is an insulating material that covers many vertebrate axons; fatty-type covering of axons that increases the speed of axonal transmission; sheet of fatty substance that develops around the neurons to promote faster transmission of electrical signals through the nervous system. Please see also Myelin .
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.
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.
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. The various combinations of these preferences result in 16 personality types
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).
