| aphthae major | A severe form of aphthae characterised by unusually numerous, large, deep, and frequent ulcers; healing may take as long as six weeks and results in scarring. Synonym: Mikulicz' aphthae, periadenitis mucosa necrotica recurrens, recurrent scarring aphthae, Sutton's disease. (05 Mar 2000) |

| arteria palatina major | <anatomy, artery> Anterior branch of descending palatine artery, supplying the gums and mucous membrane of the hard palate. Synonym: arteria palatina major. (05 Mar 2000) |
| bursa of teres major | Bursa under the tendon of the teres major near its attachment. Synonym: bursa subtendinea musculi teretis majoris. (05 Mar 2000) |
| camera oculi major | The space between the cornea anteriorly and the iris/pupil posteriorly, filled with a watery fluid (aqueous humor) and communicating through the pupil with the posterior chamber. Synonym: camera anterior bulbi, camera oculi anterior, camera oculi major. (05 Mar 2000) |
| canalis palatinus major | The canalis formed between the maxilla and palatine bones; it transmits the descending palatine artery and the greater palatine nerve. Synonym: canalis palatinus major, pterygopalatine canal. (05 Mar 2000) |
| variola major | <disease, virology> This acute viral disease once claimed a high mortality rate, but was officially announced as globally eradicated in 1979. This was due to who vaccination programs. Headache, vomiting and fever precede, the eruption of a widespread rash that is raised, vesicular and finally pustular. The eruption follows a set pattern of dissemination, commencing on the head and face. When the final stage is passed scars (pockmarks) are left to disfigure the skin. (27 Sep 1997) |

| major depression | A clinical syndrome that includes a persistent sad mood or loss of interest in activities that persists for at least 2 weeks in the absence of external precipitants. This should not be confused with a grief reaction (death of loved one). Features may include change in eating habits, insomnia, early morning wakening, lack of interest, depressed mood, fatigue and suicidal thoughts. (27 Sep 1997) |

| major epilepsy | tonic-clonic seizure |
| major histocompatibility complex |
cell surface markers (also known as HLA markers) that determine receptor shape and allow immune cells to recognize components of the body (ie, to distinguish "self" from "non-self"). MHC molecules are necessary for antigen presentation and recognition of antigens by immune system cells.

| major histocompatibility complex |
two classes of molecules on cell surfaces. MHC class I molecules exist on all cells and hold and present foreign ANTIGENS to CD8 CYTOTOXIC T LYMPHOCYTES if the cell is infected by a VIRUS or other MICROBE. MHC class II molecules are found on the IMMUNE SYSTEM's ANTIGEN PRESENTING CELLS and display antigen to activate CD4 CELLS.

| major histocompatibility complex |
A group of genes that control aspects of the immune response. The products of these genes, the histocompatibility antigens, are present on every cell of the body and serve as markers to distinguish self from nonself cells. See also Antigen; Histocompatibility Testing.

| major histocompatibility complex |
Special marker proteins that, when linked to antigen fragments on an antigen-presenting cell, enable T cells to recognize and neutralize the antigen. Cytotoxic T cells recognize or "see" antigens in the context of MHC class I molecules. Helper T cells recognize or "see" antigens in the context of MHC class II molecules.
