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:

  • (1) In some areas, the tumor shows a striking resemblance to Kaposi's sarcoma; criss-crossing fascicles of spindle cells are interspersed with narrow vascular spaces, but PAS-positive hyaline globules are absent.

  • (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.
