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 process
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 process
alveolar process
the part of the bone in either the maxilla or mandible that surrounds and supports the teeth.
anconeal process
the point of the elbow; a prolongation vertically of the ulna.
articular process
one of the pair of processes at each end of a typical vertebrae which articulate with adjacent vertebral articular processes.
arytenoid cartilage corniculate process
a horn-like process which extends dorsomedially and forms one side of the caudal margin of the entrance to the larynx.
basihyoid lingual process
a median process which projects from the basihyoid bone into the root of the tongue in the horse and cow.
basilar process
a quadrilateral plate of the occipital bone projecting superiorly and anteriorly from the foramen magnum.
caudate process
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 process
any of the three (anterior, medial and posterior) processes of the sphenoid bone.
condylar process
carries the articular surface with which the mandible articulates with the temporal bone at the temporomandibular joint.
coracoid process
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 process
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 process
the process on the dorsal border of the distal phalanx to which the common digital extensor tendon is attached.
ensiform process
xiphoid process.
ethmoid process
a bony projection above and behind the maxillary process of the inferior nasal concha of some species.
frontal process
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 process
the bony core of the horn which projects from the frontal bone.
frontonasal process
an expansive facial process in the embryo that develops into the forehead and upper part of the nose.
malar process
zygomatic process of the maxilla.
mamillary process
a tubercle on each cranial articular process of a lumbar vertebra.
mandibular angular process
a process which protrudes from the ventral caudal angle of the mandible, and acts as the attachment of the digastric muscle.
mastoid process
a conical projection at the base of mastoid portion of temporal bone.
odontoid process
a toothlike projection of the axis that articulates with the atlas. See also dens.
paracondylar process
a prominent process lateral to the occipital condyle at the caudal extremity of the skull.
pterygoid process
one of the wing-shaped processes of the sphenoid bone.
retroarticular process
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 process of vertebrae
a dorsal median process of a vertebra giving attachment to muscles of the back.
styloid process
a long, pointed projection, particularly a long spine projecting downward from the inferior surface of the temporal bone.
suprahamate process
a flat, caudally directed process on the acromion of cats and some other species.
tail vertebral hemal process
paired ventral processes of the more cranial tail vertebrae; the coccygeal vessels run between them.
uncinate process
any hooklike process, as of vertebrae, the lacrimal bone, or the pancreas.
urethral process
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 process
the caudal sternebra, consisting of a rod of bone that typically supports a xiphoid cartilage. Called also xiphoid.
zygomatic process
a projection from the frontal or temporal bone, or from the maxilla, by which they articulate with the zygoma.

The body mass of the bank vole is best correlated with three mandibular characters--total length of mandible at processus articularis excluding incisors, length of mandible excluding incisors, and maximum height of mandible excluding coronoid process, and three maxillary characters--zygomatic skull width, length of cranial (upper) diastema, and length of foramen incisivum.
