Rabbit hair scale pattern. key words: morphology, hair, wool, cuticular scales, rabbit, Angora INTRODUCTION The guard hair shaft diameter, the medullary index and scale length were measured using image analysis software. Try to make your observations toward the middle of the hair. The microarchitecture of the cover hairs, wool hairs and tactile (sinus) hairs of feral, New Zealand White and Angora rabbits was studied by means of scanning electron microscopy. The spinous scale pattern is a petal-like pattern made up of triangular scales that protrude from the cuticle. (a) Human head hair (600x), (b) dog fur (1250x), (c) Deer hair (120x), (d) Rabbit fur (300x), (e) Cat fur (2000x), (f) Horse hair (450x). . Another reason why one may study hairs is for animal distribution; certain areas are surveyed to determine if a species is present in that area. Jul 1, 2004 · Cuticle scale patterns and medullae characteristics were determined by using available animal hair keys in literature as a guide. from publication: Scanning electron microscopic study of different hair types in The scale pattern on a hair is one of the important identifying characteristics and can almost always be used as a “finger print”. A) Transition between root segment and base of the shaft showing barely Download scientific diagram | SEM pictures of cuticular scale patterns of wool hair in a New Zealand White rabbit. Scale bars = 10 mm. Figure 5 shows the scale pattern of hair from the rabbit (Oryctolagus cuniculus). key words: morphology, hair, wool, cuticular scales, rabbit, Angora INTRODUCTION Figure H-3: Scale or cuticle patterns of several different kinds of hair. A spinous cuticle pattern was found in the rat (fancy hooded), rabbit, cat (calico), and deer. Feb 1, 2001 · D) SEM view of the shield region of a cross-sectioned cover hair of a feral rabbit showing the regular waved pattern of the cuticular scales, the dumb-bell profile and the broad multicellular medulla. The basic shape of the hair scale, the cortex distribution and the medulla of different fineness were studied. Every species has its own scale pattern unique to them. Scale bars = 20 mm. The hair scale pattern, scale margin type, and distance between scales were identified. B Gelatine casts of cuticular scale patterns of dorsal cover hairs. In Microscopy of Hair Part I: A Practical Guide and Manual for Human Hairs Rabbit Hair Medulla style fragmented Medulla thickness: thick Medulla transparency: opaque (thick) Cuticle thickness: thin Cortex color: grey Cuticle scales: flat and smooth Other characteristics: rabbit hair is semi-transparent The pattern of the scales on the surface of the hair can sometimes be useful in identifying the species. A) Single chevron pattern at the transition between the base and the mid-segment of a New Zealand White rabbit The morphology and variability of the cuticular scale patterns, hair cortex, medullary | Hair, Rabbit and Wool | ResearchGate, the professional network for scientists. The hair scale pattern was imbricate in large ruminants, goat, and horse; coronal (crown‐like) in During the course of a criminal investigation, the identification and comparison of human and animal hairs can be helpful in demonstrating physical contact with a suspect, victim, and crime scene. These included Deedrick and Koch (2004b) SEM pictures of cuticular scale patterns along a dorsal cover hair of a New Zealand White rabbit. Scale bars = 50 mm. The morphology and variability of the cuticular scale patterns, hair cortex, medullary arrangement and profile of the ha … Hence, the morphological structure of rabbit hair was investigated again in this study, using optical microscopy and the scanning electron microscopy. Hairs can provide investigators with valuable information for potential leads. Spinous scales are found in the proximal (root) region of the fur hair of some animals, including bobcat, chinchilla, fox, lynx, mink, mouse, otter, raccoon, rat, sable, sable, seal, and sea lion. It was concluded that the scanning electron microscopic observation of hair samples is a fast and valuable method for iden- tifying hair types with useful applications in different disciplines such as mam- malian biology, the textile industry and forensic medicine. A) Petal pattern at the basal segment of the hair shaft. The thin, pointed tip of an animal hair often has a different Cuticle Scale Pattern than the rest of the hair. B) Torsion image obtained when the scale margins are observed under an oblique angle (New Zealand White rabbit). aqt zcffs djfgq stpiimu bpxyz coa ivq podcxn qbjmr kntr
