Ecdysis
Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa. Since the cuticle of these animals typically forms a largely inel
Cephalothorax aka prosoma
The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together,
Asynchronous Muscles
Asynchronous muscles are muscles in which there is no one-to-one relationship between electrical stimulation and mechanical contraction. These muscles are found in 75% of 
Thorax (arthropod anatomy)
The thorax is the midsection (tagma) of the hexapod body (insects and entognathans). It holds the head, legs, wings and abdomen. I
Egg Case (mermaid’s Purse)
An egg case or egg capsule, often colloquially called a mermaid’s purse, is the casing that surrounds the eggs of oviparous chondrichthyans. Living chondricthyans tha

Relaxin
Relaxin is a protein hormone of about 6000 Da,[1] first described in 1926 by Frederick Hisaw.[2][3] The relaxin family peptide hormones belong to the insulin superfamily an
Theca folliculi

The region where the crescentic masses of the ectoderm and endoderm come into direct contact with each other constitutes a thin membrane, the buccopharyngeal membrane (or oropharyngeal membrane), which forms a septum between the primitive mouth and pharynx.
In front of the buccopharyngeal area, where the lateral crescents of mesoderm fuse in the middle line, the pericardium is afterward developed, and this region is therefore desi
Rete pegs (aka rete processes or rete ridges or papillae) are epithelial extensions that project into the underlying connective tissue in both skin and mucous membranes.
In the epithelium of the mouth, the attached gingiva exhibit rete pegs, while the sulcular and junctional epithelia do not. Scar tissue lacks ret
Thermolysin is used in the industrial synthesis of aspartame. It catalyzes the formation of the peptide bond between aspartic acid and phenylalanine methyl ester, resulting in aspartame.
Both thermolysin and snake venom metalloproteinases (SVMPs) share a similar mechanism of action, utilizing zinc ions to hydrolyze peptide bonds in proteins
Pituri, aka mingkulpa, is a mixture of leaves and wood ash traditionally chewed as a stimulant (or, after extended use, a depressant) by Aboriginal Australians widely across the continent.
