What's the difference between prehensile and prehension?
Prehensile
Definition:
(n.) Adapted to seize or grasp; seizing; grasping; as, the prehensile tail of a monkey.
Example Sentences:

(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.
Prehension
Definition:
(n.) The act of taking hold, seizing, or grasping, as with the hand or other member.
Example Sentences:
(1) Results indicate substantial postoperative improvement in tip prehension and grasp, while performance remained essentially unchanged for lateral prehension, pinch force, and power grip.
(2) Our conclusion is that, although distance and type of prehension affect the transportation component, they are computed separately in programming this component.
(3) A left bias in the population for prehension, predicted by recent theories, was not evident in any setting.
(4) The third experiment had the two-fold aim of establishing (1) whether transport velocity was influenced by object velocity once the location in space at which the object had to be grasped was fixed and (2) whether the grasp kinematics differed for prehension movements directed respectively to stationary or to moving objects.
(5) The experiment was conducted to investigate, by using kinematic parameters, the influence of the type of prehension on the transportation component in reaching-grasping movements.
(6) A detailed, kinematic analysis revealed subtle deficits in midline pointing and prehension in a patient showing good clinical signs of recovery from optic ataxia associated with bilateral parietooccipital damage.
(7) 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.
(8) Capuchins develop postural control, prehension and locomotion later than do squirrel monkeys, baboons or macaques, presenting a pattern of motor development intermediate between these relatively more precocial genera and apes.
(9) The patients have continued to improve in their rehabilitation, and the Krukenberg forceps with its improved prehension and sensibility has improved the quality of life of these people.
(10) Three main groups of neurons were distinguished: "Precision grip neurons", "Finger prehension neurons", "Whole hand prehension neurons".
(11) This study examined the contribution of binocular vision to the control of human prehension.
(12) Nondysfunctional older subjects were observed resetting identical prehension patterns secondary to lateral pinch weakness, which contributed to increased prehension pattern frequency and performance time.
(13) Prehension involves processing information in two hypothesized visuomotor channels: one for extrinsic object properties (e.g., the spatial location of objects) and one for intrinsic objects properties (e.g., shape and size).
(14) In the case of distal neurons there was a relationship between the type of prehension coded by the cells and the size of the stimulus effective in triggering the neurons.
(15) By means of this Tobelbader Hand the prehension can be dosed muscularly.
(16) Effective prehension can usually be achieved by proper positioning, exercises, and splinting but when grasp is poor, tendon transfers are very effective in furthering the goal of independence.
(17) The frequency modulated feedback channel signals six levels of force developed at the finger tips during prehension activities.
(18) Thumb length, so important for prehension and opposition, can be restored by phalangealization, pollicization, or toe-to-thumb transfer.
