Just one
The Humerus linked with the shoulder to the scapula and the clavicule and linked with the forearm to the Ulna (or Cubitus) and the Radius.
http://en.wikipedia.org/wiki/File:Illu_upper_extremity.jpg this is a pic of the arm bones I think you meant the forearm bones because they have 2, the radius and ulna. The upper arm is the humerus
There are two bones in the upper arm: the humerus and the ulna. The humerus is the long bone that runs from the shoulder to the elbow, while the ulna is one of the two bones in the forearm, not the upper arm.
There are three, the humerus which is the upper bone from the shoulder to the elbow, then there are two bones between the elbow and wrist called the radius and ulna. When you extent you arm to shake hands with someone, the radius is the bone on top.The arm is the part of the upper limb that goes from the shoulder to the elbow joints and its only bone is the humerus. The resot of the upper limb has the radius and ulna in the forearm, the carpals in the writs, the metacarpals in the palms and the phallangess in the digits.
The humerus is a bone. You have a left a humerus located in your left upper limb and a right humerus located in your right upper limb. The humerus is considered the bone in your arm, while the radius and ulna make up the forearm.
The Humerus (upper arm), Radius (lower arm) and Ulna (Lower arm and elbow)
Actually there are 3 bones in the arm. The Humerus, which is where your Biceps are, the Radius, which is the bone connected to your thumb, and the Ulna, which is connected to your pinky finger. I always remember Ulna, because it sounds like an old lady's name, and old lady's always have their little tea cups and stick their pinky in the air when they sip! My science teacher taught me that. <3 ya! LuvsCam :)
The elbow connects the upper arm with the lower arm.
The humerus, radius, and ulna are the bones of your arm. The humerus is the upper arm bone. In the forearm, the radius is the larger bone on the "thumb side," and the ulna is the smaller bone on the "pinkie" side.
There are two bones in the forearm, the radius and the ulna. The easiest way to remember which one is which is to extend your arm out palm facing vertically. When you look at your forearm your radius is the top bone and the Ulna is the lower bone.Or (as I did) remember it with this sentence: "The Ulna is Underneath."
The human arm is made up of three bones, the humerus (upper arm) and the ulna and radius, both of which make up your lower forearm. so: -humerus -ulna -radius
There are more than two long bones in the skeleton but if you mean the two longest bones then the femur (longest) and tibia second longest).
The brachium contains the humerus bone, which is the upper arm bone. The antebrachium contains the radius and ulna bones, which are the two bones in the forearm.
