Figure rating scale studies have also assessed body image perceptions among Caucasian, Asian, and African-American college women. African-American women chose larger ideal body sizes than did Caucasian and Asian women., [12] suggesting that each race or ethnicity may have a different concept of the ideal body type.
Female body shape or female figure is the cumulative product of a woman's bone structure along with the distribution of muscle and fat on the body. Female figures are typically narrower at the waist than at the bust and hips .
Body roundness index (BRI) is a calculated geometric index used to quantify an aspect of a person's individual body shape. Based on the principle of body eccentricity, it provides a rapid visual and anthropometric tool for health evaluation. [1] Introduced in 2013, the BRI calculation can be used to estimate total and visceral body fat.
Unlike most other molluscs, there is no intermediate stage, or veliger, between the trochophore and the adult. Instead, a segmented shell gland forms on one side of the larva, and a foot forms on the opposite side. When the larva is ready to become an adult, the body elongates, and the shell gland secretes the plates of the shell.
Body shape has effects on body posture [30] and gait, and has a major role in physical attraction. This is because a body's shape implies an individual's hormone levels during puberty, which implies fertility, and it also indicates current levels of sex hormones. [1] A pleasing shape also implies good health and fitness of the body. Posture ...
Molluscs have such diverse shapes that many textbooks base their descriptions of molluscan anatomy on a generalized or hypothetical ancestral mollusc. This generalized mollusc is unsegmented and bilaterally symmetrical with an underside consisting of a single muscular foot. [67] [68]: 484–628 Beyond that it has three further key features.
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks [a] (/ ˈ m ɒ l ə s k s /). Around 76,000 extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. [5]
The Thecosomata (lit. "case-body" [3]) have a shell, while the Gymnosomata ("naked body") do not. The two clades may or may not be sister taxa ; if not, their similarity (in that they are both pelagic, small, and transparent, and both groups swim using wing-like flaps ( parapodia ) which protrude from their bodies) may reflect convergent ...
