Contributing factors include physiologic changes, psychologic conflicts, memory loss, impaired judgment, and sleep deprivation. Defining characteristics include inaccurate interpretation of the environment; cognitive dissonance; distractibility; decreased ability to grasp ideas; impaired ability to make decisions, solve problems, or reason; disorientation to time, place, person, circumstances, or events; and inappropriate or nonreality-based thinking.
dysfunctional family p's: alcoholism a nursing diagnosis approved by the North American Nursing Diagnosis Association, defined as psychosocial, spiritual, and physiological functions of the family unit that are chronically disorganized, leading to conflict, denial of problems, resistance to change, ineffective problem solving, and a series of self-perpetuating crises. See also alcoholism.

family p's the psychosocial, physiological, and spiritual functions and relationships within the family unit; nursing diagnoses include dysfunctional family processes: alcoholism and interrupted family processes.

spinous process of vertebra a part of a vertebra projecting backward from the arch, 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.
temporal process the posterior blunt process of the zygomatic bone that articulates with the zygomatic process of the temporal bone to form the zygomatic arch.
uncinate process any hooklike process, as of vertebrae, the lacrimal bone, or the pancreas.

zygomatic process a projection in three parts, from the frontal bone, temporal bone, and maxilla, by which they articulate with the zygomatic bone (see Appendix 3-3).

cli·noid pro·cess

[TA]
one of three pairs (anterior, middle, and posterior) of bony projections from the sphenoid bone; the anterior and posterior pairs of which surround the hypophysial fossa like bedposts.
Synonym(s): processus clinoideus [TA], clinoid (2)

cli·noid pro·cess

(klin'ōyd pros'es) [TA]
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.

As anterior clinoid process covers the roof of cavernous sinus and the paraclinoidal segment of the internal carotid artery, anterior clinoidectomy becomes mandatory in approaching cavernous sinus and in optic canal decompression so the parameters measured in the present study will guide in the careful dissection in that area.
In order to approach these aneurysms, the lesser sphenoid wing bone together with the anterior clinoid process are removed extradurally, as just mentioned before.
The autors opine that anatomical knowlege of optic strut and anterior clinoid process, may be clinically important for surgeons operating in the region of cavernous sinus or the surrounding structures.
The anterior, middle and the posterior clinoid processes are located in the middle cranial fossa of the skull.
The differences between direct anatomical studies and data from lateral cephalometric radiographs have been attributed to superimposition of the overlapping clinoid processes of the sella turcica (Abdel-Kader, 2007).
In clinical practice, when a paraclinoid aneurysm occurs, the anterior clinoid process is removed as a treatment for this disease.
The relationship between the third cranial nerve and posterior clinoid process. Indian J.
The sella turcica bridge (STB) is the true bony union of the anterior and posterior clinoid processes while the clinoid enlargement (CLEN), is the overlapping of the anterior and posterior clinoid processes4 and not necessarily real bony fusion.5 Bridging of the sella turcica is considered as an anatomical abnormality and has been reported to occur in skeletal and dental malformations and in several syndromes.6
The particular emphasis of the cranial work was on the following locations: where those cranial nerves cross the borders of tentorium cerebelli, as they pass through cavernous sinus, where the particularly vulnerable spot was, the fibro-osseous canal beneath the posterior clinoid processes, at sutura petrobasilaris, and where those nerves enter the orbit through fissure orbital is superior.
In the lateral view, (1) the temperomandibular joints should be superimposed, and (2) the clinoid processes should be symmetrical.
Anteriorly, it is bounded by a bony ridge, the tuberculum sella, and posteriorly by the dorsum sella and the posterior clinoid processes. The anterior clinoid processes of the lesser wing of the sphenoid are lateral to the tuberculum sella and project posteriorly.
