What's the difference between pinnate and tuft?

Pinnate


Definition:

  • (a.) Alt. of Pinnated

Example Sentences:

  • (10) The medial pterygoid muscle with its 7 Sehnenspiegel has the most complex pinnate structure.
  • (11) The differences in angulation and length observed for the fibers of anatomical muscles may reflect two distinct mechanical requirements: arrangement for pinnation, reflecting an increase in physiological cross-section and arrangement for equivalent placement of sarcomeres, possibly associated with coordination.
  • (12) The understanding of intermediate architecture, including issues of compartmentation, pinnation, and concatenation, remains more elusive, as some morphologically distinct muscles may be functionally equivalent.
  • (13) The basic pinnate structures caused by Sehnenspiegel in the jaw muscles are already present in newborn animals.
  • (14) The medial head contains fewer type I fibers and is composed of relatively longer myofibers (15-20 mm long), also arranged in a pinnate fashion but less heavily invested with connective tissue.
  • (15) Therefore, if twisting has been minimized in New World monkeys as suggested by their thin corpora, other changes in the craniofacial musculoskeletal complex, such as different muscle recruitment or pinnation patterns, may be responsible.
  • (16) This region is largely composed of short fibers (5-7 mm long) arranged in a pinnate fashion and heavily invested with connective tissue.
  • (17) Three architectural patterns that deserve discussion are the classical arrangement of fibers in pinnate patterns, the more recent assumption of sarcomere equivalence, and the issue of compartmentation.
  • (18) Correlation of the m. triceps surae parts and degree of its pinnateness do not reveal any definite differences in connection with the complexion.
  • (19) Postnatal development of the masticatory musculature takes place on the basis of the pinnation existing prior to birth and consists in secondary pinnation.
  • (20) The PCSA of each muscle was calculated as muscle volume times the cosine of the angle of fiber pinnation divided by fiber length, where published fiber length:muscle length ratios were used to estimate fiber lengths.

Tuft


Definition:

  • (n.) A collection of small, flexible, or soft things in a knot or bunch; a waving or bending and spreading cluster; as, a tuft of flowers or feathers.
  • (n.) A cluster; a clump; as, a tuft of plants.
  • (n.) A nobleman, or person of quality, especially in the English universities; -- so called from the tuft, or gold tassel, on the cap worn by them.
  • (v. t.) To separate into tufts.
  • (v. t.) To adorn with tufts or with a tuft.
  • (v. i.) To grow in, or form, a tuft or tufts.

Example Sentences:

  • (1) This observation provides corroboration for the identification of the principal CCK-I neuron in the rat olfactory bulb as the centrally projecting middle tufted cell.
  • (2) The observed damage was similar: a decrease of the total length of the dendritic segments of the apical tuft and the basal arborization.
  • (3) The cell density in the tufts was 120 and 70 per cent greater than controls in AGN and RPGN, respectively.
  • (4) Approximately one-fourth of the cells contained cytoplasmic fibrillar bodies and amorphous fibrous tufts around the nuclear envelope.
  • (5) Stereociliary tufts in the tectorial region differ from those in the free-standing region in several ways.
  • (6) Severe mesangial insudation of material containing fibrinogen derivatives resulted in segmental tuft necrosis with almost complete replacement and destruction of the mesangial matrix.
  • (7) The anaxonic granule cell of the olfactory bulb is believed to inhibit mitral and tufted cells through reciprocal dendrodendritic synapses.
  • (8) Detached ciliary tufts (DCTs) have been observed in sputum, in cervicovaginal smears and, rarely, in fluid from the pouch of Douglas.
  • (9) Among the 58 Helicobacter-negative cases, similar changes were not observed in the ulcer edges, except for two cases which exhibited some cellular tufts.
  • (10) Monocytes were the predominant cell type among stained cells in glomerular tufts and crescents.
  • (11) At least six different cell types are recognizable: (1) nondifferentiated duct cells; (2) cells containing apical secretory granules; (3) goblet cells; the mucosubstances of type 2 and 3 are PAS- and Alcian-blue-positive, also reacting wih methenamine silver; (4) ciliated cells, containing a single cilium with the microtubular pattern 9+2; (5) tuft cells with extremely long and wide microvilli and a pear-shaped cell body; (6) migrating cells, mainly lymphocytes and some assumed eosinophils, showing reaction to Mg++-activated ATPase.
  • (12) The Tufts Assessment of Motor Performance (TAMP) was administered to 69 children (ages 6-18 years, X = 12.1, SD = 3.9) and 137 adults (ages 19-83 years, X = 46.7, SD = 20.0) with neurological and musculoskeletal impairments.
  • (13) The funniest hairstyle I’ve ever had The time I tried to give myself a touch-up with clippers and shaved out a whole tuft of hair.
  • (14) Surface areas of tufts and crescents were separately determined by photographing glomeruli, projecting and tracing outlines of tufts and crescents, and cutting out and weighing the tracings.
  • (15) S. sanguis I strains adhered better than S. sanguis II strains and peritrichously fibrillar strains generally adhered better than tufted strains.
  • (16) An adhesion is considered as a nidus for segmental sclerosis; as the adhesion progresses, the related tuft regions turn into sclerosis.
  • (17) The terminal tuft of the distal phalanx is destroyed by pressure erosion.
  • (18) That's probably why Tufts has reneged on its agreement with the government on how it plans to deal with sexual assault on campus – administrators know it's unlikely that they'll have their funding pulled as a result of their non-compliance.
  • (19) They found, in the articulation of the upper limbs, in addition to generic signs of arthrosis, zones of bone reabsorption (vacuoles), especially as regard the wrist and hands, and irregularities of the tufts.
