| middle piece | A part of the spermatozoon characterised by an axoneme and by a sheath of mitochondria arranged in a tight helix. Principal piece, the principal part of the spermatozoon, which is about 45 um long and has a characteristic fibrous sheath surrounding the axoneme. (05 Mar 2000) |
|---|---|
| piece | A part or portion. End piece, a part of the spermatozoon consisting of an axoneme surrounded only by the flagellar membrane. (05 Mar 2000) |
| end-piece | The terminal part of the tail of a spermatozoon consisting of the axoneme and the flagellar membrane. (05 Mar 2000) |
| Fab piece | The antigen-binding fragment of an immunoglobulin molecule, consisting of both a light chain and part of a heavy chain. Synonym: Fab piece. (05 Mar 2000) |
| Fc piece | <immunology> The constant region on an immunoglobulin molecule. The area that is exactly the same on all antibodies. The region is found on the heavy chains and is not involved in binding antigens. (09 Oct 1997) |
| active transport | <biochemistry, chemistry> Transport of ions, nutrients or other molecules into a cell against a concentration gradient, this requires the expenditure of energy through ATP hydrolysis. (06 May 1997) |
| anterograde transport | Movement of material from the cell body of a neuron into axons and dendrites retrograde axoplasmic transport also occurs). (18 Nov 1997) |
| atrial transport function | The role of the atria in filling and stretching the ventricles by their presystolic contraction, without which the force of ventricular contraction and hence the cardiac output may significantly decrease. (05 Mar 2000) |
| axonal transport | Directed transport of organelles and molecules along a nerve cell axon. Transport can be anterograde (from the cell body) or retrograde (toward the cell body). (alberts et al., molecular biology of the cell, 3d ed, pg3) (12 Dec 1998) |
| axoplasmic transport | Transport by way of flow of axoplasm toward cell soma (retrograde) or toward axon terminal (anterograde). (05 Mar 2000) |
| biological transport | The movement of materials (including biochemical substances and drugs) across cell membranes and epithelial layers, usually by passive diffusion. (12 Dec 1998) |
| biological transport, active | The movement of materials across cell membranes and epithelial layers against an electrochemical gradient, requiring the expenditure of metabolic energy. (12 Dec 1998) |
| vectorial transport | <physiology> Transport of an ion or molecule across an epithelium in a certain direction (e.g. absorption of glucose by the gut). Vectorial transport implies a nonuniform distribution of transport proteins on the plasma membranes of two faces of the epithelium. (06 Mar 2000) |
| paracellular transport | Solvent movement across an epithelial cell layer through the tight junctions between cells. Compare: transcellular transport. (05 Mar 2000) |
| vesicular transport | <cell biology> Process of transport of material across an epithelium by uptake on one face into a coated vesicle, which may then be sorted through the trans Golgi network and transported to the opposite face in another set of vesicles. (17 Mar 1998) |
