1. a prominence or projection, as from a bone.
2. a series of operations or events leading to achievement of a specific result; also, to subject to such a series to produce desired changes.
- accessory vertebral p. — a process which protrudes backwards from the vertebral arch of the thoracic and lumbar vertebrae and overlap the succeeding vertebra in dogs and some other species.
- acromial p. — acromion.
- alveolar p. — the part of the bone in either the maxilla or mandible that surrounds and supports the teeth.
- anconeal p. — the point of the elbow; a prolongation vertically of the ulna.
- articular p. — one of the pair of processes at each end of a typical vertebrae which articulate with adjacent vertebral articular processes.
- arytenoid cartilage corniculate p. — a horn-like process which extends dorsomedially and forms one side of the caudal margin of the entrance to the larynx.
- basihyoid lingual p. — a median process which projects from the basihyoid bone into the root of the tongue in the horse and cow.
- basilar p. — a quadrilateral plate of the occipital bone projecting superiorly and anteriorly from the foramen magnum.
- caudate p. — the right of the two processes on the caudate lobe of the liver.
- ciliary p's — meridionally arranged ridges or folds projecting from the crown of the ciliary body.
- clinoid p. — any of the three (anterior, medial and posterior) processes of the sphenoid bone.
- condylar p. — carries the articular surface with which the mandible articulates with the temporal bone at the temporomandibular joint.
- coracoid p. — a small curved process arising from the glenoid rim and neck of the scapula; called also coracoid; large in humans and animals with large clavicles.
- coronoid p. — 1. the anterior part of the upper end of the ramus of the mandible.
— 2. a projection at the proximal end of the ulna. See also coronoid process.- distal phalangeal extensor p. — the process on the dorsal border of the distal phalanx to which the common digital extensor tendon is attached.
- ensiform p. — xiphoid process.
- ethmoid p. — a bony projection above and behind the maxillary process of the inferior nasal concha of some species.
- frontal p. — 1. of the zygomatic bone forms the anterior part of the zygomatic process.
— 2. a cone-shaped mass of red vascular tissue that lies across the base of the turkey's beak. Called also snood, nasal comb.- frontal bone cornual p. — the bony core of the horn which projects from the frontal bone.
- frontonasal p. — an expansive facial process in the embryo that develops into the forehead and upper part of the nose.
- malar p. — zygomatic process of the maxilla.
- mamillary p. — a tubercle on each cranial articular process of a lumbar vertebra.
- mandibular angular p. — a process which protrudes from the ventral caudal angle of the mandible, and acts as the attachment of the digastric muscle.
- mastoid p. — a conical projection at the base of mastoid portion of temporal bone.
- odontoid p. — a toothlike projection of the axis that articulates with the atlas. See also dens.
- paracondylar p. — a prominent process lateral to the occipital condyle at the caudal extremity of the skull.
- pterygoid p. — one of the wing-shaped processes of the sphenoid bone.
- retroarticular p. — a flange of bone which protrudes ventrally from the caudal end of the zygomatic arch; carries part of the articular surface of the temporomandibular joint on its rostral edge.
- spinous p. of vertebrae — a dorsal median process of a vertebra giving attachment to muscles of the back.
- styloid p. — a long, pointed projection, particularly a long spine projecting downward from the inferior surface of the temporal bone.
- suprahamate p. — a flat, caudally directed process on the acromion of cats and some other species.
- tail vertebral hemal p. — paired ventral processes of the more cranial tail vertebrae; the coccygeal vessels run between them.
- uncinate p. — any hooklike process, as of vertebrae, the lacrimal bone, or the pancreas.
- urethral p. — an extension of the urethra beyond the end of the glans penis in the male horse, sheep and goat. In the horse it is buried in a deep recess. In the small ruminants it is a thin, loose, wormlike appendage.
- xiphoid p. — the caudal sternebra, consisting of a rod of bone that typically supports a xiphoid cartilage. Called also xiphoid.
- zygomatic p. — a projection from the frontal or temporal bone, or from the maxilla, by which they articulate with the zygoma.
