It projects from the anterior extremity of the upper costa of the Scapula, q. v. and is a little crooked, with its point inclining forwards: a ligament passes from its superior part, to connect it to the acromion and clavicle. At the birth it is cartilaginous, and called anchoralis processus; anchyroides, cor-nicularis, conchyroides, processus.

Coracoides musculus. See Coraco-brachiaeus. It is called coracoides, because it proceeds from the process which is formed like a crow's beak.

Corda tympani. The portio dura of the seventh pair of nerves having entered the tympanum, sends a small branch to the stapes, and another more considerable one, which runs across the tympanum from behind forwards, passes between the long leg of the incus and the handle of the malleus, then goes out at the same place where the tendon of the anterior muscle of the malleus enters. It is called chorda tympani, because it crosses the tympanum as a cord crosses the bottom of a drum.

Dr. Monro thinks that the chorda tympani is formed by the second branch of the fifth pair, as well as by the portio dura of the seventh.
