What's the difference between pulley and trochlear?
Pulley
Definition:
(v. t.) A wheel with a broad rim, or grooved rim, for transmitting power from, or imparting power to, the different parts of machinery, or for changing the direction of motion, by means of a belt, cord, rope, or chain.
(b. t.) To raise or lift by means of a pulley.
Example Sentences:

(16) The transverse fibers of the palmar aponeurosis are attached by vertical septa to the underlying transverse metacarpal ligament and thus form a pulley over the flexor tendons.
(17) The synthetic Nitex pulley appears to have the potential to function as an effective fibro-osseous pulley replacement.
(18) The triple-locking loop and three-loop pulley patterns were close in strength and only the triple-locking loop was stronger than the double-locking loop.
(19) The long-term results of the key grip procedure (tenodesis of the flexor pollicis longus tendon to the radius, release of the A1 pulley, and percutaneous pin fixation of the interphalangeal joint of the thumb) were evaluated in 10 tetraplegic patients.
(20) Satisfactory grip functions were restored for all patients after the secondary pulley reconstruction.
Trochlear
Definition:
(n.) Shaped like, or resembling, a pulley; pertaining to, or connected with, a trochlea; as, a trochlear articular surface; the trochlear muscle of the eye.
Example Sentences:
(1) A medium amount of degenerated terminals were observed in the nucleus pretectalis anterior (pars reticularis), the dorsal part of the periaqueductal grey at its most rostral levels, the caudolateral parts of the nucleus pretectalis posterior and the nucleus of optic tract, the H field of Forel, parts of the somatic cell columns of the oculomotor nucleus and the trochlear nucleus.
(2) A 5-year-old boy had accessory calcaneus (os trochleare) with pain, shoe pressure, and a varus position of the foot not reported previously.
(3) The electrical activity of single trochlear motoneurons (TMns) and axons of second order vestibular neurons presumably terminating on these motoneurons were studied during natural stimulation of semicircular canals and otolith organs in cats anesthetized with Ketamine.
(4) It proved impossible to identify the boundary between the oculomotor nucleus and trochlear nucleus in the coronal sections so that in such sections the combined total of neurons in both nuclei was estimated.
(5) This lesion was probably responsible for the bilateral trochlear nerve dysfunction.
(6) Taken with electromyographic data from other studies, these results indicate that superior oblique myokymia reflects spontaneous discharge of trochlear motor neurons that have undergone regenerative changes.
(7) Most of the caudal articular surfaces of the humeral condyles, the caudal perimeter of the radius, and the trochlear notch and portions of the anconeal process of the ulna could be identified.
(8) However, simple radiographic methods enable detection of both patellar instability and the often associated trochlear depth insufficiency.
(9) Trochlear nerves from two human fetuses, and digital nerves from a third, have been examined by electron microscopy.
(10) We report a patient who developed an isolated trochlear nerve palsy following minor head trauma.
(11) A case of neurinoma of the trochlear nerve presenting with the sudden onset of headache followed by transient paresis of the right trochlear nerve in a 37-year-old woman is reported.
(12) Horseradish peroxidase and Fast Blue were injected into the oculomotor and trochlear nuclei of rabbits so as to study the distribution of vestibular neurons that project to these nuclei.
(13) Medial trochlear lip osteophytes were not found in the studies of normal elbows but were noted in 20% of ulnar nerve entrapment cases.
(14) Cell counts of the trochlear nucleus on day 19 indicate a mean increase of 37% (range 19--62%) in the number of cells on the experimental side (contralateral to the graft) as compared to the ipsilateral control nucleus of the same embryos.
(15) Only in one specimen was the trochlear nerve adherent to the ophthalmic division of the trigeminal nerve.
(16) Sex, duration of diabetes, insulin dependence, and neuropathy were not significantly associated with an increase in trochlear calcifications.
(17) Cell counts made after the period of cell death indicated a significant decrease in the final number of surviving trochlear motor neurons.
(18) Since trochlear motor neurons are generated prior to the formation of afferent synapses on them, it is unlikely that the reduction in the number of motor neurons initially produced is due to reduced afferent synaptic input.
