The mammillary bodies also mamillary bodies, are a pair of small round brainstem nuclei. [2] They are located on the undersurface of the brain that, as part of the diencephalon, form part of the limbic system. They are located at the ends of the anterior arches of the fornix. [3]
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Animation of a two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.
Historically, it was believed that only insects had mushroom bodies, because they were not present in crabs and lobsters. However, their discovery in the mantis shrimp in 2017 lead to the later conclusion [2] that the mushroom body is the ancestral state of all arthropods, and that this feature was later lost in crabs and lobsters.
In insect physiology and anatomy, the corpus allatum (plural: corpora allata) is an endocrine gland that generates juvenile hormone; as such, it plays a crucial role in metamorphosis. Surgical removal of the corpora allata (an allatectomy ) can cause an immature larva to pupate at its next molt , resulting in a miniature adult. [ 1 ]
The M4+2 engine, also known as the double-piston internal combustion engine, is a type of internal combustion engine invented by Polish patent holder Piotr Mężyk. [1] The M4+2 engine took its name from a combination of two-stroke engines and four-stroke engines. The two-stroke combustion engine is characterized by a simple construction and ...
Human remains were found by a city employee in a deep well at a waste water collection point located off of Lexington Road near South Padre Island Drive on Monday afternoon, according to Corpus ...
Each crus represents the tapering, posterior fourth of each corpora cavernosa penis; the two corpora cavernosa are situated alongside each other along the length of the body of penis while the two crura diverge laterally in the root of penis before attaching firmly onto either ischial ramus at their proximal end.
