What's the difference between latency and patency?
Latency
Definition:
(n.) The state or quality of being latent.
Example Sentences:

(13) Both startle amplitude and onset latency showed significantly greater facilitation in the preschool children than in the 8-year-olds and adults.
(14) Between-group responsivity differences suggest developmental retardation in term (38-42 weeks) SGA newborns, but the faster SGA latencies may reflect 'induced' acceleration in auditory neurophysiologic function.
(15) It was also established that the right-left differences in the H-reflex latencies were directly related to the degree of the right-hand preference in the female subjects.

(17) All median latencies of waves III and V in the study group were significantly higher than those of the control children.
(18) Peak latencies from all recording sites clustered into two distinct groups--those that included N1 from 'TME,' peak 'I' of the 'A' record and trajectory amplitude peak 'a' of 3-CLT, and those that included the negative peak of '8-AP' and trajectory amplitude peak 'b' of 3-CLT, as well as peak 'II' of the 'A' record, when present.
(19) Rooting latency showed a significant additive maternal strain effect but little systematic effect of pup genotype.
(20) Giving pontine rabbits 6-OHDA elicited a short-latency fall in blood pressure, resembling the hypotensive phase in intact animals.
Patency
Definition:
(n.) The condition of being open, enlarged, or spread.
(n.) The state of being patent or evident.
Example Sentences:
(1) Experiments have been performed using CO2 laser-assisted microvascular anastomoses, and they demonstrated the following features, in comparison with conventional anastomoses: ease in technique; less time consumption; less tissue inflammation; early wound healing; equivalency of patency rate and inner pressure tolerance; but only about 50 percent of the tensile strength of manual-suture anastomosis.
(2) Central assessment of the angiograms revealed a patent infarct-related artery in 78 patients (patency rate 66%, 95% confidence limits 57 to 74%).
(3) This noninvasive but precise imaging modality demonstrates the potential value of using MRI to evaluate the diameter of small vessels, including the postoperative monitoring of arterial bypass graft patency in peripheral regions.
(4) a) To determine the frequency of perforations in latex surgical gloves before, during, and after surgical and dental procedures; b) to evaluate the topographical distribution of perforations in latex surgical gloves after surgical and dental procedures; and c) to validate methods of testing for latex surgical glove patency.
(5) We use this procedure to assess the excitability of the auditory nerve, the patency of the cochlea and to detect undesirable side effects of electrical stimulation, such as facial nerve activation.
(6) Forty-eight reinterventions in 34 limbs were required to restore or maintain graft patency in thrombosed or failing grafts.
(7) Corresponding rates for secondary patency at 6 years were 51.4% and 76.4% (p < 0.005).
(8) No patient had a previous infarction, and none underwent intervention seeking to restore coronary patency.
(9) The "animal" rings almost constantly caused local phlebitis, but these changes were not reflected in the patency rates at one week.
(10) Minor technical errors may jeopardize the patency of femoral-popliteal bypass grafts.
(11) Intraarterial digital subtraction angiography (DSA) was performed to evaluate graft patency in 45 patients undergoing coronary artery bypass grafting with the use of internal mammary artery (IMA).
(12) The results should be analysed by the Kaplan-Meier estimator, and patency rates should be compared by the log-rank test or Gehan's test.
