(n.) A nocturnal carnivorous mammal (Cercoleptes caudivolvulus) of South America, about as large as a full-grown cat. It has a prehensile tail and lives in trees. It is the only representative of a distinct family (Cercoleptidae) allied to the raccoons. Called also potto, and honey bear.
Example Sentences:
(1) Electroretinogram (ERG) flicker photometry was used to measure the spectra of the cone photopigments for members of two nocturnal species, the raccoon (Procyon lotor) and the kinkajou (Potos flavus), and a diurnal species, the coati (Nasua nasua).
(2) Whereas the raccoon and kinkajou are monochromatic, the diurnal coati is a dichromat having an additional class of cone photopigment with peak sensitivity close to 433 nm.
(3) It was possible to correlate skin depigmentation with the course of leishmanial infection in one animal, a young kinkajou, Potos flavus.
(4) Since the termination of pyramidal tract fibers on or very near spinal motor neurons is a prerequisite even for the peculiar kind of dexterity seen in some non-primates (e.g., raccoon, kinkajou), this one feature alone seems to be a critical factor.
Prehensile
Definition:
(n.) Adapted to seize or grasp; seizing; grasping; as, the prehensile tail of a monkey.
Example Sentences:
(1) However, during the dynamic phase of the task (grasping and lifting), the monkeys increased the prehensile force in multiple steps, suggesting that they relied on sensory feedback from the fingers to attain an adequate grip force to lift the object rather than programming the lift in advance.
(2) When properly applied in selected patients, this single-stage microsurgical procedure can restore prehensile function, improve the appearance of the hand with multiple digital amputations, and preserve near-normal donor-foot function.
(3) Assessment of functional status and measurements of prehensile capabilities showed that all patients had improved after surgery.
(4) After explaining the tertiary patterns of prehension the possibilities of restoring prehensile function in patients after high cervical spinal injury (C4-C6) by means of orthotics or operation are discussed.
(5) Lastly, in rheumatoid arthritis, the results in terms of pain, mobility and prehensile strength were good, apart from 2 failures due to progression of rheumatoid disease (cases unsuitable for this treatment).
(6) Kinematic analyses revealed that prehensile movements made under monocular viewing differed substantially from those performed under binocular conditions.
(7) The prehensile activity and looking behavior of 2- and 5-month-old infants were videotaped in the presence of objects placed within and beyond possible contact distance.
(8) Descending spinal pathways have been described in 'non-dextrous' avian species (chickens, ducks, geese and pigeons), and the purpose of this study was to determine if there are any differences in the origins of descending projections to the spinal cord in 'dextrous' or prehensile parrots (sulphur-crested cockatoo, Cacatua galerita, and eastern rosella, Platycerus eximius).
(9) This study provides the first clear kinematic evidence that binocular vision (stereopsis and possibly vergence) makes a significant contribution to the accurate programming of prehensile movements in humans.
(10) Certain deformities require very early treatment in order to permit prehensile function to the developing infant, or to release the impaired part.
(11) Limited nighttime observations (2130 until 0630) revealed no effects (P greater than .10) of forage on grazing time or number of prehensile bites taken.
(12) In carefully selected adult acquired spastic hemiplegic patients, release of the annular ligament at the base of the thumb can functionally restore the transverse arch of the hand, improve thumb opposition and improve prehensile capacity.
(13) The discharge frequency of some dentate and interpositus neurons could be correlated with prehensile force as well as velocity of wrist movement and torque developed by wrist muscles.
(14) All patients showed prominent reduction of number, duration and severity of attacks of Raynaud's phenomenon, improvement of prehensile strength, healing of finger ulcerations and improvement or normalization of digital photoplethysmography.
(15) It suggests that researchers have concentrated unduly upon the use of feedback to control prehensile force or joint angle and advocates a broader perspective.
(16) The mobility of the distal radioulnar joint, along with the prehensile thumb and increasing brain function, are hallmarks of the late-evolving hominids.
(17) The results are analysed for each aetiological group in terms of pain, mobility prehensile strength after more than one year of follow-up.
(18) The prehensile grip configurations of infants aged 4 through 8 months were examined as they grasped objects that varied in size and shape.
(19) Beside the importance of its prehensile function the human hand plays an essential role in the conveyance of expression.
(20) This results in a unpleasant stump of poor prehensile quality.
