atomic mass  atomic weight; used particularly when describing a single isotope of a nuclide.

inner cell mass  embryoblast.

lean body mass  that part of the body including all its components except neutral storage lipid; in essence, the fat-free mass of the body.

molar mass  (M ) the mass of a molecule in grams (or kilograms) per mole.

molecular mass  the mass of a molecule in daltons, derived by addition of the component atomic masses. Its dimensionless equivalent is molecular weight.

relative molecular mass  technically preferable term for molecular weight. Symbol M r.

mass (ms)

n.

1. A unified body of matter with no specific shape.

2. A grouping of individual parts or elements that compose a unified body of unspecified size or quantity.

3. The physical volume or bulk of a solid body.

4. Abbr. m The measure of the quantity of matter that a body or an object contains. The mass of the body is not dependent on gravity and therefore is different from but proportional to its weight.

5. A thick, pasty pharmacological mixture containing drugs from which pills are formed.

6. One of the seven fundamental SI units, the kilogram.

7. See massa.

mass-action ratios

the ratio of substrate to product, where the predominance of one, usually the substrate, over the other thermodynamically favors a particular direction for a reaction.

inner cell mass

an internal cluster of cells at the embryonic pole of the blastocyst which develops into the body of the embryo.

lean body mass

that part of the body including all its components except neutral storage lipid; in essence, the fat-free mass of the body.

mass medication

(or immunization, or treatment, or prophylaxis, or testing, or screening) application of the procedure to all of the animals in the population, which may be as small as a herd or as large as a national herd. This sort of strategy has been used extensively and for many years in the control of diseases of animals, and has been the principal reason for the dramatic virtual eradication of the major plagues in many countries. The unintelligent extension of the strategy to the control of wastage caused by endemic disease has contributed most to the problem of residues of antibacterial drugs in the human food chain. See also mass medication.

mass number

the number used to express the mass of a nucleus, being the total number of nucleons, protons and neutrons in the nucleus of an atom or nuclide; symbol A.

mass reflex

reflex actions by all the body parts controlled by the part of the spinal cord which has been injured.

thalamic intermediate mass

see interthalamic adhesion.

mass

A cohesive aggregate of often similar components, composition, cells or molecules; the amount of matter contained in a body. See Biomass, Critical mass Physical exam An aggregate of tissue with a different consistency than is normal for a particular body region. See Breast mass.

Patient discussion about been a mass.

Q. What does it mean when you have breast cancer in three different areas? My friend just found out that she has breast cancer in her right breast but three different lump types of cancer in one breast, and it has affected her lymph nodes at least two of them. What are her chances and what stage cancer would that be? She is going to be having a mastectomy and chemo.

A. Did they biopsied the lumps? Are they sure they are cancerous? If so that means it might got metastasized, the cancerous cells can move around in the blood stream and then just start “hook” on an organ and continue multiplying. That is a malignant and dangerous situation.

Q. Lump in the breast! Hi buddy! My gf is 30. For the past 3 months she is feeling something hard, marble like and lumpy in her breast which moves within its own place. I don't get on with her GP so don't want to go about this lump. Is there anywhere in UK where I can take her and have a mammogram and pay?

A. Hi. Where I live we have a NHS mobile mammogram unit (kinda like a mobile home) that travels around the county. It's completely free to go and you don't need an appointment. You just drop in. I've never been but i'm pretty sure my mother has and it's all very easy. I don't know where you live (I'm in Essex, UK) but this might be worth looking into.

Q. A lump in my armpit Hi, Last week after the shower I found a small painful lump in my right groin. I went to see a doctor and he prescribed me some antibiotics. I’ve been taking it for 5 days and the lump is still there. I’m 31, usually healthy and work-out in the gym regularly, don’t smoke or use drugs and don’t take any medications. Is that dangerous? Should I go and see another doctor?

A. What you describe sounds like enlarged lymph node. The first diagnosis that’s suspected in such case is an infection that makes it painful. The antibiotics you take need several more days to act, so currently it doesn’t sound suspicious. If the lump persist, it’d be wise to consult you doctor
