| processus ciliaris | 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) |

| processus clinoideus | 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) |
| processus cochleariformis | 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) |
| processus condylaris | 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) |
| processus coracoideus | 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) |
| processus coronoideus | 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) |
| processus costalis | An apophysis extending laterally from the transverse process of a lumbar vertebra; it is the homologue of the rib. Synonym: processus costalis. (05 Mar 2000) |
| processus ethmoidalis | A projection of the inferior concha, situated behind the lacrimal process and articulating with the uncinate process of the ethmoid. Synonym: processus ethmoidalis. (05 Mar 2000) |
| processus falciformis | A continuation of the inner border of the sacrotuberous ligament upward and forward on the inner aspect of the ramus of the ischium. Synonym: processus falciformis, falciform ligament, ligamentum falciforme. (05 Mar 2000) |
| processus ferreini | The centre of the renal lobule, which has the shape of a small, steep pyramid, consisting of straight tubular parts; these may be either ascending or descending limbs of the nephronic loop or collecting tubules. Synonym: pars radiata lobuli corticalis renis, Ferrein's pyramid, processus ferreini. (05 Mar 2000) |
| processus frontalis maxillae | The upward extension from the body of the maxilla, which articulates with the frontal bone. Synonym: nasal process, processus frontalis maxillae. (05 Mar 2000) |
| processus frontalis ossis zygomatici | The process of the zygomatic bone which extends upward to form the lateral margin of the orbit and articulates with the frontal bone and greater wing of the sphenoid bone. Synonym: frontosphenoidal process, processus frontalis ossis zygomatici. (05 Mar 2000) |
| processus gracilis | A slender spur running anteriorward from the neck of the malleus toward the petrotympanic fissure. Synonym: processus anterior mallei, Folli's process, follian process, long process of malleus, processus gracilis, processus ravii, Rau's process, Ravius' process, slender process of malleus. (05 Mar 2000) |
| processus intrajugularis | A small pointed process of bone extending from the middle of the jugular notch in both the occipital and the temporal bones, the two being joined by a ligament and dividing the jugular foramen into two portions. Synonym: processus intrajugularis. (05 Mar 2000) |
| processus jugularis | A short process jutting out from the posterior part of the condyle of the occipital bone, its anterior border forming the posterior boundary of the jugular foramen. Synonym: processus jugularis. (05 Mar 2000) |
