Quote pp. 263-264

§. CCCCLXXX.

Acetabularum structura, et vsus,

Sunt autem amplissima cauatam mirifice coxis adposita, vt iisdem coxae cum toto trunco diuersimode super femora moueri et inclinari possint. Quaelibet sinuositas caput femoris profundius excipiens proprie acetabulum, Gr. κοτύλῃ vocatur (§. LXXVI.), ex concursu trium ossium componitur (§. CCCCLXXVII.), et crusta cartilaginea obducitur ac augetur (§. CCCCLXVIII); defectus vero in imperfecta ipsius ora ab opposita cartilagine suppletur, et per incisuram (§. CCCCLXXXI.) vasa, a compressione libera, tutissime admittuntur. Totus denique sinus validissimo, ex supercilio eius inaequali pro deunte ligamento, firmissime cum capite ossis femoris unitur.

§. 480.

The structure of the acetabulum and its appearance,

However, there are very large cavities wonderfully placed near the hips to allow them to move and bend in various ways relative to the entire torso. Each depression in which the head of the femur is deeply embedded is called the acetabulum proper, in Greek κοτύλῃ (§. 76), consists of a connection of three bones (§. 477), is covered with a cartilaginous layer and expanded (§. 468); but there is a defect, which at the edge is filled with the opposite cartilage, and through the incision (§. 481) the vessels, free from compression, are safely passed. In the end, the entire sinus is very strong, thanks to the uneven edge, with the missing ligament, it is firmly connected to the head of the femur.

Quote p. 264

§. CCCCLXXXI.

corumque sminor in ima parte cauitas.

Quum vero anterius et lateraliter ex parte dehifcat, supercilium illius imperfectum et inaequale fit, immo sinuositas, quae in medio et versus ilia latescit, ad hiatum rursus angustatur. Cauitas minor, quam in ima parte continet, simili gaudet margine imperfecto et inaequali, ac aspera superficie, eaque non solum ligamentum teres siue planum recipit, verum etiam glandulae mucilaginosae tutissimum concedit locum, efficitque, ne tota sub motu comprimatur.

§. 481.

smaller cavity at the bottom.

Where the rupture occurs anteriorly and laterally, its [acetabulum] edge becomes incomplete and uneven, and the notch, which extends from the middle outward, narrows again to a fissure. The smaller cavity which it [the acetabulum] contains in the lower part, also has the same interrupted and uneven edge and a rough surface, which not only receives the round or flat ligament, but also provides the safest place for the mucous glands, preventing them from being completely compressed when movements.

Quote pp. 324-325

§. DLXXXVIII.

eiusque inaequalis fossa qua ligamentum teres educitur

In medio profundam et inaequalem fossam habet, ex qua ligamentum firmissimum, crassum, et elasticum educitur, quod propriae acetabuli crenae inseritur (§. CCCCLXXXI), et, vi officii, suspensorium dici meretur.

§. 588.

and its irregular fossa, through which the round ligament passes.

In the middle there is a deep and uneven fossa, from which emerges a very firm, thick and elastic ligament, which is attached to its own notch of the acetabulum (§. 481), and by its function deserves to be called suspensory.

Quote pp. 325-326

§. DXC.

Connexio capitis femoris cum acetabulo.

In commissura capitis cum collo femoris, et circulo praecipue circa basin ceruicis aspero, ligamentum vasis refertissimum, robustum, validumque capsulare, quod caput ossis femoris cum acetabulo iungit (§. CCCCLXXX), firmatur. Quo vero liberius in centro acetabuli versari, et absque vasorum, illud ingredientium (§. CCCCLXXXI.) compressione, ex glanduloso-pinguedinosis organis mucus capsam inter et caput femoris exprimi, nec, relaxato forsan articulari vinculo, os prorsus ex articulatione elabi possit; natura suspensorio prospexit ligamento (§. DLXXXVIII).

§. 590.

Connection of the head of the femur with the acetabulum.

At the junction of the head with the neck of the femur and especially around the base of the neck, there is a very dense, strong and powerful capsular ligament that connects the head of the femur with the acetabulum (§. 480) and secures it. It allows the head of the femur to move freely inside the acetabulum and without compressing the vessels entering it (§. 481), under pressure the mucus from the glandular-fatty organs is squeezed out between the acetabulum and the head of the femur, and, even if the articular ligament [capsule] weakened, the bone cannot slide completely out of the joint; is because nature has focused on the suspensory ligament (§. 588).

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

Fragments of t he book Pollux J. Onomasticum (166-76) edited by E. Bethe (1900). In Greek the author calls ligamentum capitis femoris (LCF) «ἰσχίον», and the concept of «ligament» is designated by the term «νεῦρον / ν εῦρα ». The term «ἰσχίον» was used by Rufus of Ephesus ( 2020ArkhipovSV_ProlyginaIV ). The fragment of the Onomasticum dealing with the LCF was quoted by Giovanni Filippo Ingrassia ( 1603IngrassiaeIP ) .
