Which term describes an armlike branch of bone?

Explanation:
An armlike branch of a bone is called a ramus. In skeletal anatomy, a ramus describes a projection that extends from the main body of a bone and often serves as a site for muscle or ligament attachment or helps form a joint. For example, the mandible has a ramus that rises from the body and, with other parts, participates in the jaw joint. This distinguishes it from a spine, which is a sharp, slender projection; a line, which is a small, thin ridge; and a process, a general term for any projection. So the specific armlike extension is the ramus.
