| reversible process | <chemistry> A cyclic process carried out by a hypothetical pathway, which leaves the universe exactly the same as it was before the process, no real process is reversible. For chemical systems we consider a process at equilibrium to be reversible. Examples are phase transitions that occur at the melting point or boiling point temperatures at 1 atm pressure.

| mental process | The prominence of the chin at the anterior part of the mandible. Synonym: protuberantia mentalis, mental process. (05 Mar 2000) |
| ciliary process | One of the radiating pigmented ridges, usually seventy in number, on the inner surface of the ciliary body, increasing in thickness as they advance from the orbiculus ciliaris to the external border of the iris; these, together with the folds (plicae) in the furrows between them, constitute the corona ciliaris. Synonym: processus ciliaris. (05 Mar 2000) |
| Civinini's process | A sharp projection from the posterior edge of the lateral pterygoid plate of the sphenoid bone. Synonym: processus pterygospinosus, Civinini's process. (05 Mar 2000) |
| clinoid process | One of three pairs of bony projections from the sphenoid bone: anterior clinoid process, the recurved posterior angle of the lesser wing; middle clinoid process, a little spur of bone on the body of the sphenoid, posterolateral to the tuberculum sellae; posterior clinoid process, a spur of bone at each superior angle of the dorsum sellae. Synonym: processus clinoideus, clinoid. (05 Mar 2000) |
| cochleariform process | A bony angular process (the termination of the septum of the auditory tube) above the anterior end of the vestibular window, forming a pulley over which the tendon of the tensor tympani muscle plays. Synonym: cochleariform process, processus trochleariformis. (05 Mar 2000) |
| weldon's process | <chemistry> A process for the recovery or regeneration of manganese dioxide in the manufacture of chlorine, by means of milk of lime and the oxygen of the air; so called after the inventor. Source: Websters Dictionary (01 Mar 1998) |
| condylar process | The articular process of the ramus of the mandible; it includes the head of the mandible, the neck of the mandible and pterygoid fovea. Synonym: processus condylaris, condyloid process, mandibular condyle. (05 Mar 2000) |
| condyloid process | The articular process of the ramus of the mandible; it includes the head of the mandible, the neck of the mandible and pterygoid fovea. Synonym: processus condylaris, condyloid process, mandibular condyle. (05 Mar 2000) |
| conoid process | The prominence near the lateral end of the inferior surface of the clavicle that gives attachment to the conoid ligament. Synonym: tuberculum conoideum, conoid process. (05 Mar 2000) |
| muscular process of arytenoid cartilage | The blunt lateral projection of the arytenoid cartilage giving attachment to the lateral and posterior cricoarytenoid muscles of the larynx. Synonym: processus muscularis cartilaginis arytenoidei. (05 Mar 2000) |
| coracoid process | A long curved projection from the neck of the scapula overhanging the glenoid cavity; it gives attachment to the short head of the biceps, the coracobrachialis, and the pectoralis minor muscles, and the conoid and coracoacromial ligaments. Synonym: processus coracoideus. (05 Mar 2000) |
| coronoid process | A sharp triangular projection from a bone; coronoid process of the mandible, the triangular anterior process of the mandibular ramus, giving attachment to the temporal muscle; coronoid process of the ulna, a bracket-like projection from the anterior portion of the proximal extremity of the ulna; its anterior surface gives attachment to the brachialis, its proximal surface enters into the formation of the trochlear notch. Synonym: processus coronoideus. (05 Mar 2000) |
| costal pit of transverse process | A facet on the transverse process of a vertebra for articulation with the tubercle of a rib. Synonym: fovea costalis processus transversi, costal pit of transverse process. (05 Mar 2000) |
