The tibia of each hind leg is depressed on its outer side, and upon the edges of this depression stand two rows of stiff hairs which are bent over the groove.
The tibia and the planta of the hind leg of the worker bee are greatly flattened.
By this action the pollen is squeezed between the end of the tibia and the surface of the auricle and is forced upward against the distal end of the tibia and on outward into contact with the pollen mass accumulating in the corbicula.
From the lateral boundaries of this depression spring many long hairs, some of which arch over the concave outer surface of the tibia and thus form a kind of receptacle or basket to which the name corbicula or pollen-basket is given.
The lower or distal end of the tibia articulates at its anterior edge with the planta.
The middle leg of each side is raised and its planta is brought into contact with the upper (proximal) end of the tibia of the same side and with the pollen mass.
The outer surface of the tibia is marked by an elongated depression, deepest at its distal end, and bounded laterally by elevated margins.
The remaining portion of this end of the tibia is flattened and slightly concave, its surface sloping upward from the inner to the outer surface of the limb.
With each upward stroke of the auricle small masses of pollen which have been scraped from the plantar combs by the pecten are caught and compressed between the spiny surface of the auricle and the surface of the tibia above it.
These parts suffer most because as Mr. Morris says: ‘During extension they resist rotation outwards of the tibia upon a vertical axis’ and a sprained knee is almost always caused by a twist outwards of the foot.
PLATE 4, Figure 18, “tibia and fibula” are misprinted for “ulna and radius.
The TIBIA is the main bone of the leg, and extends from knee to ankle, on the inside of the limb.
The least modified mammals, in fact, have the radius and ulna, the tibia and fibula, distinct and separate.
The tibia (T) has no marked crest at its upper end, and its lower end is narrow and not pulley-shaped.
In a young bird, however, the pulley-shaped apparent end of the tibia is a distinct bone, which represents the bones marked As.
The tibia has a strong crest at its upper end and its lower extremity passes into a broad pulley.
The radius and ulna, the tibia and the fibula, are distinct, and the short crowned molar teeth are anchitherold in pattern.
Even gentle handling in the course of performing the necropsy may occasion a lesion of this kind--of the tibia at the knee, of the radius or ulna at the wrist, or indeed at any of the epiphyseal junctions.
Not infrequently subperiosteal hemorrhages occur, giving rise to exquisitely tender swellings, especially of thetibia or of the femur, or of the ramus of the lower jaw, as has been noted in connection with guinea-pig scurvy.
A frequent site of this lesion is at the wrist or at the knee, involving the head of the tibia or the lower end of the femur.
The common site of fracture is the lower part of the tibia or fibula.
The disease, as represented in the two first cuts, was of the most acute kind, and a great part of the shaft of the tibia had perished.
In these accidents it is not unfrequently found that one or other malleolus has given way, or that the lower end of the tibia is split.
The lower portion of the tibia is sometimes longitudinally split by bending inwards of the foot, the patient having fallen from a considerable height; occasionally the inner malleolus is broken transversely.
The astragalus was found lying betwixt the back of the tibia and the tendo-Achillis, its upper articulating surface facing forwards, the lower in contact with the tendon.
This has occurred, so as to prove fatal at a considerable period after the operation, in consequence of the posteriortibia being cut close to its origin, and no clot having formed in it.
In one instance the greater part of the astragalus was taken away, along with the ends of the tibia and fibula.
The tibia is broken at its upper part near the tuberosity, with or without similar injury of the fibula.
The bones nearest the surface are principally affected: a swelling gradually forms on the tibia or ulna, without discoloration of the integuments, and without pain occurring till after a long time.
Fracture of the upper part of the tibia is to be treated in the straight position, for it has been already observed, that when the knee is bent the upper portion necessarily projects.
He made an incision along the spine of the tibia of about three inches in extent; another shorter one was made to fall on this at right angles from the inner side.
Posterior tibia in male dilated without spurs, in female with all spurs present.
In the Ainu the tibia is rather flattened at its angular part, but the Shikotan Ainu have a nearly circular tibia.
I do not know of any other existing race in the world in which such an extraordinary phenomenon occurs, and the tibia struck me also as being extremely long, while the femur appeared proportionately short.
However, with the exception that the tibia is more circular than with the Ainu of Yezo, I could not see any material difference between them and the other Ainu.
The Tibia is much rounder than with the Yezo Ainu.
The shorter tibia makes the whole leg of the Bornean peoples shorter than in others -- except that the Punans make it up with a longer femur.
Other Indonesian peoples have a longer upper arm than the Ulu Ayars, who also have the tibia shorter in proportion to the femur.
In these specimens the ratio of the length of the tibia to the snout-vent length is 55.
The articulation between the tibia and astragalus is more complex than in other mammals, the end of the malleolus entering into it.
The femur has a small third trochanter, the radius and ulna and tibia and fibula are respectively separate, at least in the young, and the fibula articulates with the astragalus.
A fracture that has healed and joined the tibia (upper bone) to the fibula in a specimen of T.
At the extremity of the tibia there is a strong spine.
The curious and exceptional character of a tibia shorter than the tarsus in the adult female, as observed above, is found only in this genus and some Acanthococcidæ.
Eyes and feet as in adult, but there is no fringe on thetibia and tarsus.
Feet long, slender, with somewhat large trochanter; on the tibia and tarsus a fringe of hairs as in the female.
The feet have large coxæ and femora; the tibia is only about half as long as the tarsus; the lower digitules are only fine hairs.
Feet very small; the femur rather thick; the tibia is shorter than the tarsus by about one-third; the four digitules are long fine hairs.
In all others a tibia shorter than the tarsus would indicate an immature insect.
Feet normal; thetibia is somewhat thin, and has one spine or hair at its tip.

S] As a rule, a tibia shorter than the tarsus characterizes an insect not yet arrived at the adult stage.
Approximately two-thirds of the distance down the crus the muscle gives rise to the tendon of insertion which passes through the fibrous loop near the distal end of the tibia in company with the m.
Near the distal end of the tibia the muscle gives rise to the tendon of insertion that passes through a groove on the anterolateral edge of the tibia just above the external condyle.
The insertion is by means of a broad, thin tendon on a ridge on the medial surface of the tibia immediately distal to the head of this bone.
The common belly is attached by fleshy fibers to the posterior surface of the tibia and fibula for two-thirds of the distance down the crus.
This strong, pinnate muscle is deeply situated along the posterior surfaces of the tibiaand fibula.
The insertion is fleshy along a narrow line on the anteromedial edge of the head of the tibia and on the medial region of the patellar tendon.
The tibia (T) has no marked crest at its upper end, and its lower end is narrow and not pulley-shaped.
In a young bird, however, the pulley-shaped apparent end of the tibia is a distinct bone, which represents the bones marked As.

The drum-stick bone or tibia in Dimorphodon, with its slender fibula, like that of a Bird, also resembles a Bird in the rounded and pulley-shaped terminal end which makes the joint corresponding to the middle of the ankle bones in man.
