(Greek: body; mass)

idiosoma, idiosome
That region of the acarine body (lice, tick) which is posterior to the gnathosoma.
An abnormal chromosome with two identical arms due to duplication of one arm and loss of the other arm.

Isochromosomes are found in some girls with Turner syndrome (chromosome disorder in females that is characterized by the absence of all or part of a second sex chromosome in some or all cells), patients with the Pallister-Killian syndrome (a condition with multiple malformations at birth and mental retardation), and some tumors.

1. Characterized by a slight, narrow bodily framework.
2. Having a small, slender physique.
Having an abnormally large body.
mesosoma, mesosomia
1. A body of medium size or stature.
2. The middle of the body of some invertebrates; especially, when the phylogenetic segmentation pattern cannot be determined.
3. The middle portion of the body in an invertebrate; especially, the anterior portion of the abdomen in certain arthropods.
That division of the acarine body that has the third and fourth pairs of legs.
1. The posterior part of the body, or tagma (grouping of arthropodan segments; such as, the head, the thorax, and the abdomen with a common function), of arthropods (an invertebrate animal having an exoskeleton or an external skeleton, a segmented body, and jointed appendages or body parts that may extend from a body segment) whose body is composed of three parts; such as, the metasoma, and the other two being the prosoma and the mesosoma.
2. The posterior region of the body of certain invertebrates, a term used especially when the phylogenetic segmentation pattern cannot be identified.
1. The process by which the chemical composition of a rock is changed by interaction with fluids; replacement of one mineral by another without melting.
2. The gradual change in rock structure caused by the natural replacement of chemicals through interaction with liquids or gases.
3. Etymology: from meta-, "beside, after" + Greek sōmat-, "body".
microsome, microsoma
1. A tiny granule in the cytoplasm where protein synthesis takes place.

Cytoplasm is the protoplasm of a cell excluding the nucleus which is full of proteins that control cell metabolism.

A granule refers to a tiny grain.

2. A small cytoplasmic body composed of fragments of endoplasmic reticulum and associated ribosomes.
1. A condition of having an abnormally small and underdeveloped yet otherwise perfectly formed body with normal proportionate relationships of the various parts of the body.
2. A body that is abnormally small.

A child with microsomia is considered to have significant undergrowth or smallness of the body.

Dwarfism; the state of being a dwarf; underdevelopment of the body or some part of the body.

A dwarf is defined as a person who is unusually short, particularly one of atypical proportions; also called, a nanus. It also includes an animal or plant that is abnormally small in size.

The region of a siphonophore colony that bears nectophores (medusae specialized for propulsion).

An order of Hydrozoa (various simple and compound polyps and jellyfish) consisting of various free-swimming or floating pelagic mostly delicate transparent and often colored forms that are usually regarded as compound animals composed of zooids modified to perform various functions for the colony: such as, feeding, defense, and locomotion; which sometimes have two or more zooids in the form of a bell so that by their contractions they cause the colony to swim, and which often have a hollow float which keeps the colony afloat.

nullisomatic, nullisomic
A pair of chromosomes that are totally missing.

In this condition, the same homologous chromosome will be missing; such as, a human cell which does not have the thirteenth chromosome totally or both of the pairs are missing. This is always lethal in the case of humans.

A fatty inclusion within a cell.
1. The hind-part of the body of an arachnid, consisting in the most primitive forms of thirteen segments and a telson, but tending to become shortened and very variable in the majority of the more specialized forms.

In spiders, it forms a more or less globular and apparently unsegmented "abdomen". In scorpions, it forms a segmented tail with a sting at the end.

2. The posterior or back part of an arachnid's body, behind the prosoma (cephalothorax or head).

Although it is similar in most aspects to an abdomen (and is often referred to as such), the opisthosoma is differentiated by its inclusion of the respiratory organs and the heart. The number of segments and appendages on the opisthosoma vary.
