(pros′es″) [L. processus, going forwards, an advance] 1. A method of action. 2. The state of progress of a disease. 3. A projection or outgrowth of bone or tissue. 4. A series of steps or events that lead to achievement of specific results.
alveolar p. The portion of the mandible and maxilla containing the tooth sockets. SYN: alveolar bone.
articular p. of vertebra One of four small, flat processes (two superior and two inferior) by which vertebrae articulate with each other.
ciliary p. One of about 70 prominent meridional ridges projecting from the corona ciliaris of the choroid coat of the eye to which the suspensory ligament of the lens is attached. These have the same structure as the rest of the choroid and secrete aqueous humor, which nourishes neighboring parts, the cornea, and lens.
clinoid p. Any of three pairs of bony processes on the top of the body of the sphenoid bone, overhanging the edges of the sella turcica.
condyloid p. A posterior process on the superior border of the ramus of the mandible consisting of a capitulum and neck. It articulates with the mandibular fossa of the temporal bone. SEE: mandible for illus.
coracoid p. A beak-shaped process extending upward and laterally from the neck of the scapula. The coracoid process is not part of any bone-to-bone articulation although the coracoclavicular ligament holds the clavicle against the acromium of the scapula. The muscles attaching to the coracoid process are the pectoralis major, coracobrachialis, and the short head of the biceps brachii. SEE: scapula.
coronoid p. 1. The process on the proximal end of the ulna that forms the anterior portion of the semilunar notch. 2. The process on the anterior upper end of the ramus of the mandible that serves for attachment of the temporalis muscle. SEE: mandible for illus.
due p. The standard or customary application of prevailing laws or rules and the protections that follow from their application.
frontal p. An upward projection of the maxilla that articulates with the frontal bone; forms part of the orbit and nasal fossa.
group p. Group dynamics (1)
lenticular p. A knob on the incus, articulating with the stapes.
mastoid p. A horn-shaped process of the mastoid portion of the temporal bone extending downward and forward behind the external auditory meatus. It serves for attachment of the sternocleidomastoid, splenius capitis, and longissimus capitis muscles.
nursing p. SEE: nursing process.
odontoid p. A toothlike process extending upward from the axis and about which the atlas rotates. SYN: dens. SEE: illus.
