The nasal dimensions are also used to classify nasal morphology into five types: Hyperleptorrhine is a very long, narrow nose with a nasal index of 40 to 55. Leptorrhine describes a long, narrow nose with an index of 55–70. [35]
The nasal bones are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and by their junction, form the bridge of the upper one third of the nose. Each has two surfaces and four borders.
The power series nose shape is generated by rotating the y = R(x/L)n curve about the x -axis for values of n less than 1. The factor n controls the bluntness of the shape. For values of n above about 0.7, the tip is fairly sharp. As n decreases towards zero, the power series nose shape becomes increasingly blunt.
Nasal cavity. The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, [1] also known as fossae. [2] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal ...
A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool. A male member of conical form (that is, with a taper) fits into the female socket, which has a matching taper of equal angle . Almost all machine tool spindles, and many power tool spindles, have a taper as their primary method ...
Anatomical terminology. [ edit on Wikidata] A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and ...
Distribution of penis sizes by circumference. 81% of erect penises (green) are between 10 and 13 cm in circumference. [2] While results vary slightly across reputable studies, the consensus is that the mean human penis, when erect, is in the range 12.9–15 cm (5.1–5.9 in) in length.
Sizes As with other catheters, NPAs are measured using the French catheter scale , but sizes are usually also quoted in millimeters. [3] [4] Typical sizes include: 6.5 mm/28FR, 7.0 mm/30FR, 7.5 mm/32FR, 8.0 mm/34FR, and 8.5 mm/36FR.
Rhinoceros. A rhinoceros ( / raɪˈnɒsərəs /; from Ancient Greek ῥινόκερως (rhinókerōs) 'nose-horned'; from ῥίς (rhis) 'nose', and κέρας (kéras) 'horn'; [1] pl.: rhinoceros or rhinoceroses ), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates ...
Nostril. A nostril (or naris / ˈnɛərɪs /, pl.: nares / ˈnɛəriːz /) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove ...
