CHAP. XIX.

Of the Bones of the Cubit.

THese are in number two; to wit, the lesser above called Radius, and the larger below called Ʋlna. Their substance is firm and solid, all but their appendages. They are near of the same length (but the Ʋlna is the longer of the two) and both have a cavity in which they con∣tain a marrowy substance. They are somewhat rough in their superficies by reason of their lines that are appointed for the rise or insertion of the Muscles.

The Ʋlna is larger in its upper end that joints with the Os humeri,* 1.1 and grows smaller and smaller towards the Hand, ending into a round Tubercle, with a round Sinus in it, (having on its hinder side a small sharp Process, from its shape call'd Styloides) whereby it is knit (by Arthrodia) to the little Bones of the Wrist, by Ligaments, (a Cartilage intervening.) Its upper end is ar∣ticulated with the Os humeri by Ginglymus, to which end it has two Processes, of which the hinder enters into the hinder cavity of the Shoul∣der-bone behind the Trochlea, (by which the Cu∣bit is stayed from further extension than to a streight posture) and is called Ancon or Olecra∣num. And at the same end it has also two Sinus, by the outer and less whereof it receives the head of the Radius, and by the hinder and larger one of the Processes of the Os humeri, which moves in it as a Rope in a Pully. As it receives the Radius in

its upper end, so is it received by it in its lower: but in the midst it bends or recedes a little from it, yet is knit to it by a long Ligament.

The second Bone is upper and something shor∣ter,* 1.2 called Radius. Its upper end is slenderer, having a round head, one side of which is received by the Ʋlna; but its tip has a round shallow ca∣vity in it, which receives a Process of the Os hu∣meri, by Diarthrosis. Its lower end is thicker, which by a little Sinus in its side receives the Ʋl∣na; and at its extremity it has two other small Sinus, into which it admits the two first and high∣est Bones of the Carpus.
