Scutes on an alligator foot. A scute (/ s k j uː t / ⓘ) or scutum (Latin: scutum; plural: scuta "shield") is a bony external plate or scale overlaid with horn, as on the shell of a turtle, the skin of crocodilians, and the feet of birds.
Roman rectangular scutums of later eras were smaller than Republican oval scutums and often varied in length from approximately 37 to 42 in (94 to 107 cm) tall (approximately 3 to 3.5 Roman feet, covering the shoulder to top of knee), and 24 to 33 in (61 to 84 cm) wide (approximately 2 to 2.7 Roman feet).
They are distinguished from the Argasidae by the presence of a scutum. [2] In both the nymph and the adult, a prominent gnathosoma (or capitulum, mouth and feeding parts) projects forward from the animal's body; in the Argasidae, conversely, the gnathosoma is concealed beneath the body.
Scutum is a small constellation. Its name is Latin for shield, and it was originally named Scutum Sobiescianum by Johannes Hevelius in 1684. Located just south of the celestial equator, its four brightest stars form a narrow diamond shape.
This shield was adapted by Roman legions and referred to by them as a scutum. [8] The Roman scutum was an oblong shield with an oval shape. [5] [8] Numerous shields were used by the Roman soldiers, such as the pelta, parma and clypeus. [8] In contrast to the scutum, these shields were round. [8]
Haemolymph contains molecules, ions and cells; [1] regulating chemical exchanges between tissues, haemolymph is encased in the insect body cavity or haemocoel. [ 1 ] [ 59 ] It is transported around the body by combined heart (posterior) and aorta (anterior) pulsations, which are located dorsally just under the surface of the body.
The scutoid explains how epithelial cells (the cells that line and protect organs such as the skin) efficiently pack in three dimensions. [1] As epithelial tissue bends or grows, the cells have to take on new shapes to pack together using the least amount of energy possible, and until the scutoid's discovery, it was assumed that epithelial ...
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 ...
