(1) A prospective study would also be useful in assessing the intrinsic and extrinsic risk factors at play in short track speed skating.(2) The thyroid cartilage and epiglottis are connected to the hyoid bone, and the cricoid cartilage is connected to the trachea by the extrinsic ligaments of the larynx.(3) Migration to other countries is in any case not extrinsic to the formation of such a nationalism.(4) The more precisely we understand how the machine works intrinsically, the better we can deduce the contribution of extrinsic factors.(5) Because of its observational nature, our study cannot differentiate between intrinsic or extrinsic factors in the reduced reproductive success.(6) Motivation can be intrinsic (from the student) and extrinsic (from external factors).(7) Thus three-dimensionality was extrinsic to painting, which was essentially flat, in Greenberg's view.(8) Pressure ulcers result from numerous intrinsic and extrinsic factors.(9) Only bourgeois art, which has become autonomous in the face of demands of employment extrinsic to art, has taken up positions on behalf of the victims of bourgeois rationalization.(10) Additional movement is caused by extrinsic muscles that arise from various cranial surfaces and enter the base of the tongue, pulling the tongue towards their attachments.(11) It is unconditionally envisaged as homogeneous extension, extrinsic to the distributions which occupy it.(12) Unlike the upper esophageal sphincter, the lower sphincter is not pulled open by extrinsic musculature.(13) Causes can include intrinsic factors, such as high seed set, or extrinsic factors, such as a loss of competitors or herbivores.(14) Other workers have, however, tended to view the diversifications as resulting from a complex mix of intrinsic biological and extrinsic physical factors.(15) At this juncture, I reassert that population change in a given area is conditioned by its intrinsic and extrinsic factors.(16) In the original conception of this study, motivators were dichotomized into intrinsic and extrinsic factors.
