Acicular
Definition:

(20) Acicular and rhomboidal clefts, some with a characteristic notch, were observed mainly in extracellular locations, although they were also associated with dying fibroblasts.
Lanceolate
Definition:
(a.) Alt. of Lanceolated
Example Sentences:
(1) Many of the lanceolate receptors contained multiple unmyelinated axons, and the usually highly ordered circular innervation of the inner conical body was markedly abnormal.
(2) In lanceolate endings, asymmetric membrane densities existed between the neurite and its Schwann cell, the Schwann cell showing signs of pinocytotic activity at all sides of its plasma membrane.
(3) The guard hairs usually are richly innervated with fully developed piloneural complexes composed primarily of a pallisade of lanceolate endings and a circumferential array of Ruffini and free nerve endings.
(4) Together with their enveloping Schwann cells, numerous lanceolate axon terminals are organized into a well-defined discoid end organ, referred to as the 'baroreceptor unit'.

(7) The Merkel cells and lanceolate receptors of the intermediary zone were completely deafferented by 24 hours after the nerve injuries.
(8) Other growth cones having vermiform, lanceolate, spatulate, and bulbous forms were observed throughout the optic pathway at all stages examined, although the longer (up to 70 micrograms) wormlike structures appeared only in the optic tract during the early period of outgrowth.
(9) The lanceolate terminals are the rapidly adapting terminals that are numerous in guard hairs.
(10) The organism has a lanceolate body 7-10.5 micrometers in length; a well developed undulating membrane; a stout, tubular axostyle with periaxostylar rings that terminate in a cone-shaped segment projecting from the posterior end of the cell; and a moderately wide costa.
(11) Eighteen hours after nerve lesion, the large-diameter myelinated nerves supplying the lanceolate receptors of the intermediary zone and the Merkel cells of the stratum basale contained areas of focal axoplasmic abnormalities, and some of the nerve terminals exhibited vacuolization, mitochondrial swelling, and disruption of the neurofilament pattern.
(12) Lanceolate nerve terminals, free endings, Merkel cells with nerve terminals and unmyelinated fibers are observed, but encapsulated endings are lacking in and aound the follicles.
