What's the difference between fascicle and lacertus?
Fascicle
Definition:
(n.) A small bundle or collection; a compact cluster; as, a fascicle of fibers; a fascicle of flowers or roots.
Example Sentences:

(10) Most examples measure less than or equal to 0.5 cm and are composed of a partially encapsulated mass of bland Schwann cells and innumerable tiny axons arranged in interlacing fascicles.
(11) Second, the percentages of subjects with 1 or more fascicles exceeding the proposed threshold were as follows: 45.8% for the four-component, 28.8% for the three-component, and 32.7% for the two-component contracture test.
(12) They aggregate to form fascicles that lie among somatic axons, being separated from them.
(13) The ipsilateral fascicles projected to almost all the above mentioned nuclei, but these projections were comparatively sparse.
(14) Biopsied fascicles of cutaneous nerves from clinically affected (forearm) and from clinically unaffected (leg) regions permitted a comparison of well-advanced and early pathologic lesions, respectively.
(15) Most often, however, brain stem lesions also involve structures surrounding the ocular motor nuclei or fascicles, sometimes leading to characteristic eponymic syndromes.
(16) Microelectrodes were inserted percutaneously into a fascicle of the peroneal nerve to measure sympathetic discharge to muscle.
(17) Ethylenethiourea (ETU), at greater than or equal to .5 mM concentrations, caused in monocell layers in vitro a necrosis of neuronal cells and a marked depression in the formation of neurites and fascicles without any noticeable change in the non-neuronal cells.
(18) At highest risk were 186 patients with blocks involving the right bundle and at least one fascicle of the left bundle which were not documented on prior electrocardiograms.
(19) Grafts with myotubes at right angles to the nerve fascicles supported nerve regeneration but at a slower rate.
(20) Microneurographic techniques were used to isolate single afferent axons within cutaneous and motor fascicles of the median and ulnar nerves at the wrist in thirteen subjects.
Lacertus
Definition:
(n.) A bundle or fascicle of muscular fibers.
Example Sentences:
(1) Less common causes of compression are: fibrous bands from the superficial head of the pronator teres; bands from the superficialis arcade; the nerve running deep to both heads of the pronator; and compression by a double lacertus fibrosus.
(2) The surgical incision of the loge of Guyon, the carpal channel, the forearm and proximal of the lacertus fibrosus was persuaded.
(3) By cutting the lacertus fibrosus the complaints and symptoms completely disappeared.
(4) In all cases surgically treated compression of the median nerve has been found at one of three levels, in the following order of frequency: the pronator teres, the flexor superficialis arch, and the lacertus fibrosus.
(5) Moreover, the lacertus fibrosus arises from this lamina close to the distal tendon and blends with the fascia of the forearm and joins the extensor carpi radialis muscle.
(6) Traumatic rupture of the lacertus fibrosus in the biceps aponeurosis and elongation of a normal-appearing biceps tendon caused weakening in elbow flexion and forearm supination.
(7) In the case presented bizonal compression of the nerve was seen, first by the lacertus fibrosus, second by an isolated abnormal tendon of the brachialis muscle.
(8) The nerve supply for the biceps tendinous intersection arises from the intramuscular rami of the musculo-cutaneous nerve, whereas the lacertus fibrosus is provided with some cutaneous rami of the same nerve.
(9) The biceps brachii tendinous intersection and lacertus fibrosus are provided with free and encapsulated nervous endings.
(10) All three patients experienced complete recovery after release of the lacertus fibrosus.
(11) After nonoperative therapy failed, surgical exploration revealed compression of the median nerve at the level of the lacertus fibrosus.
