| uniovular twins | Identical twins, twins which are the result of a single zygote (fertilized egg) splitting into two cell masses and becoming two individuals. The twins are genetically identical and are always of the same sex (both males or both females). Compare: dizygotic twins. (09 Oct 1997) |
| uniovulate | <botany> Containing but one ovule. Origin: Uni- + ovulate. Source: Websters Dictionary (01 Mar 1998) |
| unipara | A woman who has borne one child. Origin: NL. See Uniparous. Source: Websters Dictionary (01 Mar 1998) |
| uniparental inheritance | <genetics> A type of inheritance in which the offspring of a mating has the phenotype (observable physical traits) of only one parent. (09 Oct 1997) |
| uniparous | 1. <zoology> Producing but one egg or young at a time. 2. <botany> Producing but one axis of inflorescence; said of the scorpioid cyme. Origin: Uni- + L. Parere to bring forth. Source: Websters Dictionary (01 Mar 1998) |
| unipennate | 1. Having a feather arrangement on one side; resembling one-half of a feather. 2. Denoting certain muscles with fibres running at an acute angle from one side of a tendon. Synonym: demipenniform. Origin: uni-+ L. Penna, feather (05 Mar 2000) |
| unipennate muscle | <anatomy> A muscle with a lateral tendon to which the fibres are attached obliquely, like one half of a feather. Synonym: musculus unipennatus. (05 Mar 2000) |

| unipolar | 1. <physics> Having, or acting by means of, one pole only. 2. <anatomy> Having but one pole or process; applied to those ganglionic nerve cells which have but one radiating process; opposed to multipolar. <physics> Unipolar induction, the simulation sometimes produced when one electrode of an induction apparatus is applied to a nerve. Synonym: unipolar induction action. Origin: Uni- + polar. Source: Websters Dictionary (01 Mar 1998) |
| unipolar arc | <radiobiology> Arc between a metal surface and a plasma in contact with it. Such an arc requires only one electrode and is maintained by the thermal energy of the electrons. (09 Oct 1997) |
| unipolar cell | A neuron whose cell body emits a single axonal process resulting from the fusion of two polar processes during development; at a variable distance from the cell body, the process divides into a peripheral axon branch extending outward as a peripheral afferent (sensory) nerve fibre, and a central axon branch that enters into synaptic contact with neuron's in the spinal cord or brainstem. With the single known exception of the neuron's composing the mesencephalic nucleus of the trigeminus, unipolar neuron's are the exclusive neural elements of the sensory ganglia. The lack of dendritic processes of these primary sensory neuron's is only apparent: the dendritic pole of the unipolar neuron is represented by the unmyelinated terminal ramifications of the peripheral axon branch. Synonym: pseudounipolar cell, pseudounipolar neuron, unipolar cell. (05 Mar 2000) |
| unipolar electrocardiogram | An electrocardiogram taken with the exploring electrode placed on the chest overlying the heart or upon a single limb, the indifferent ("zero" potential) electrode being the central terminal. (05 Mar 2000) |
