Diploid

    Refers to a cell having two sets of chromosomes (in humans, 46 chromosomes). In contrast, a haploid cell, such as a gamete, has only one set of chromosomes (23 in humans).

RELATED TERMS
--------------------------------------

Cell
Fundamental structural unit of all life. The cell consists primarily of an outer plasma membrane, which separates it from the environment; the genetic material (DNA), which encodes heritable information for the maintainance of life; and the cytoplasm, a heterogeneous assemblage of ions, molecules, and fluid.

Chromosomes
Filaments of genetic material in every cell nucleus that are made up of genes and that transmit genetic information from one generation of cells to the next.

Contrast
"Short for ""contrast media."" Contrast media are X-ray dyes used to provide contrast, for example, between blood vessels and other tissue."

Haploid
A single set of chromosomes (half the full set of genetic material), present in the egg and sperm cells of animals and in the egg and pollen cells of plants. Human beings have 23 chromosomes in their reproductive cells.

Gamete

Diplegia, Spastic
A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)

Diplomonadida
An order of protozoa characterized by the presence of one or two karyomastigonts and either two-fold rotational or mirror symmetry.

Diplopia
Diplopia is a visual disorder that results in double vision, such that when the viewer looks at an object it seems as if there are two objects. It can arise when the eye muscles are not functioning as intended, and the eyes are not correctly aligned while focusing on an object. This binocular diplopia disappears when one eye is closed.

Diplopia, binocular
Double vision (diplopia) that is only evident when looking through both eyes and disappears if one eye is closed or covered. The condition is caused by misalignment of the eyes by the extraocular muscles (the muscles around the eyeball that control gaze). This may be due to strabismus (misalignment of the eyes from birth), neurologic damage to the extraocular muscles (as from a brain abscess, stroke, head trauma or brain tumor), diabetes, myasthenia gravis, Graves disease, or trauma to the eye muscles, as from a fracture of the orbit.

Diplopia, Cortical
A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.

Diplopia, Horizontal
A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.

Diplopia, Intermittent
A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.

Diplopia, monocular
Double vision (diplopia) in only one eye. The double vision persists when the other eye is covered. Monocular diplopia can be caused by astigmatism (abnormal curvature of the front of the cornea), keratoconus (cone-shaped cornea), pterygium (thickening of the conjunctiva over the cornea), a cataract, dislocation of the lens, a mass in the eyelid pressing on the front of the eye, xerophthalmia (dry eye), and certain retinal problems. Treatment depends upon the specific cause.
