Vibrissae present in TI and TII, generally in the form of very thick and very dense bristles (Fig.
15), frons length/ width ratio: 7:8 (HT), orbital plates extending 0.8 length of frons; posterior orbital seta moderately strong, slightly shorter than outer vertical seta; flagellomere 1 yellow pruinose basally, otherwise grey pruinose throughout, arista with 7 or 8 long dorsal branches and 3 ventral branches in addition to terminal fork; gena narrow, eye height/ genal height ratio: 12:1 (HT), silver pruinose, slightly darker beyond basal angle;
vibrissae weakly developed; palpus pale brown.
Brown and Yalden (1973) describe three different kinds of forelimb
vibrissae, "anconeal" (near the elbow), "medial antebrachial" (forearm), and "ulnar carpal" (proximal to the wrist).
In experiments designed specially to test plasticity after stroke in peri-infarct cortex, we examined plastic changes in the cortical representation of
vibrissae, induced by sensory manipulation.
Abbreviations: HBL = Head and Body Length; TL = Tail Length; HF = Hind Foot length (with claws); Ea = Ear length; MV = Mystacial
Vibrissae; TT = Tail Tuft; We = Weight; U (MW) = U-value for Mann-Whitney test.
The prominent nasal plate, protibiae without mucro, 1st ventrite shorter than 2nd and 3rd ventrites combined; tarsal claws connate at base, scrobes oblique, mentum with setae and postocular lobes with long
vibrissae indicate placement in the genus Cydianerus.
Stage 1--Hyperactivity, restlessness, and
vibrissae twitching
The
vibrissae stimulated forelimb placing test was employed to evaluate the neurofunction of rats at 1, 3, 5, 7, 9, 11, and 13 days after surgery and to assess the influence of surgery and cancer growth on neurofunction.
Leiser and Moxon (25) report that trigeminal neurons recorded from the medial-half of the trigeminal ganglion have various receptive fields in the facial skin including all major mystacial
vibrissae. More than 70% of the neurons innervating the mystacial
vibrissae responded to stimulation of the upper A-C rows, whereas our results from 16 neurons with club-like endings primarily innervate
vibrissae in the lower rows (C-E and small
vibrissae).
After this trimming of
vibrissae was done over both side for better exposure and prevention of furuncle and or boil on vestibule.
The genus Neophyllomyza Melander, 1913 (Milichiidae: Phyllomyzinae) can be separated from other genera of the subfamily Phyllomyzinae by the following characteristics: paired cruciate setae present along the middle of the front; fron-to-orbital setae extending quite to antennae, the upper ones diverging, the lower converging; face excavated, cheeks narrow, oral
vibrissae large; proboscis long, slender, geniculate; lunule small, bare; one humeral, 2 notopleural, one presutural, 2 supra-alar; one katepisternal, no anepisternal setae (Melander 1913; Brochu & Wheeler 2009).
The pattern of mouse
vibrissae follicles are modified to form mucus gland pattern and alsofeather epidermis of the chick are reported to be transformed from the chick scales epidermis.9In mammalian hair follicles development there is reciprocal induction between ectodermal epithelium and mesodermal mesenchyme.
