| mass reflex | In cases of gross injury to the spinal cord, as the stage of reflex activity follows the primary flaccidity of the shock, a condition arises in which a strong stimulus to any part of one of the paralysed limbs will be followed by contraction of the hip, knee, and ankle of the same side and often, when the stimulus is applied to the middle line of the body, of both sides, as well as of the abdominal wall, and even evacuation of the bladder and sweating over an area corresponding to the level of the lesion.

| mass screening | Organised periodic procedures performed on large groups of people for the purpose of detecting disease. (12 Dec 1998) |
| mass spectrograph | An instrument that subjects charged and accelerated ions (atomic or molecular) to a magnetic field that imparts a curved path that differs for each mass-to-charge ratio, thus separating individual species; used in detecting and assaying isotopic ratios and in molecular structure determinations. (05 Mar 2000) |
| mass stopping power | <physics> The mass stopping power (S/r) of a material for charged particles is the quotient dEs by the product of dl and r, where dEs is the average energy lost by a charged particle of specified energy in traversing a path length dl and r is the density of the medium. (16 Dec 1997) |
| MASS syndrome | <syndrome> A syndrome closely resembling both the Marfan's syndrome and the Barlow syndrome. However, no dislocation of the lenses or aneurysmal changes occur in the aorta, and the mitral valve prolapse is by no means invariable. at present it has been assigned no separate OMIM number, but shares that of the Barlow syndrome. Origin: mitral valve prolapse, aortic anomalies, skeletal changes, and skin changes. (05 Mar 2000) |
| parotid gland mass | <radiology> Pleomorphic adenoma, sialocele, adenoid cystic carcinoma, adenocarcinoma, lymphoma, lymph node, abscess, metastasis (12 Dec 1998) |
| maternal behaviour | The behaviour patterns associated with or characteristic of a mother. (12 Dec 1998) |
| passive-aggressive behaviour | Apparently compliant behaviour, with intrinsic obstructive or stubborn qualities, to cover deeply felt aggressive feelings that cannot be more directly expressed. (05 Mar 2000) |
| paternal behaviour | The behaviour patterns associated with or characteristic of a father. (12 Dec 1998) |
| relative molecular mass | The sum of the atomic weight's of all the atoms constituting a molecule; the mass of a molecule relative to the mass of a standard atom, now 12C (taken as 12.000). Relative molecular mass (Mr) is the mass relative to the dalton and has no units. See: atomic weight. Synonym: molecular mass, molecular weight ratio, relative molecular mass. (05 Mar 2000) |
| REM behaviour disorder | A disorder characterised by lack of the atonia of voluntary muscles that normally occurs in REM sleep. (05 Mar 2000) |
| cell behaviour | <cell biology> General term for activities of whole cells such as movement, adhesion and proliferation, by analogy with animal behaviour. (18 Nov 1997) |
| respondent behaviour | The behaviour in response to a specific stimulus; usually associated with classical conditioning. See: conditioning. (05 Mar 2000) |
| ceremonial behaviour | A series of actions, sometimes symbolic actions which may be associated with a behaviour pattern, and are often indispensable to its performance. (12 Dec 1998) |
| child behaviour | Any observable response or action of a child from 24 months through 12 years of age. For neonates or children younger than 24 months, infant behaviour is available. (12 Dec 1998) |
