There is only one bone in the upper arm - the humerus.
Upper arm = Humerus Lower arm = Ulna and Radius
There are 3 bones in the arm. The forearm has 2 bones, the radius and ulna. The upper arm has one bone, the humerus.
The Upper Arm is made of one bone, the Humerus. There are therefore 2 Humerus bones in any mammalian skeleton.
3 in each arm
There are three bones in the human arm: the humerus, radius, and ulna.
There are 32 bones in one human's arm...
Your radius and ulna are in your lower arm, and the humerus is in you upper arm. The radius goes from your thumb to your humerus, crossing over the ulna which goes from your pinky to your humerus. Your humerus also connects to your scapula (or shoulder blade) in what is called a "ball and socket" - the rounded end of your humerus fits perfectly into the indent in your scapula. In your fingers, you have carpals, which are your wrist bones; metacarpals, which are the palm of your hand; and phalanges, which are your finger bones.
3, the upper arm [humerus] the forearm [radius and ulna].
Three: the humerus (upper arm), ulna and radius (lower arm).
The elbow connects the upper arm with the lower 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 the bone of the upper arm, not the lower arm/forearm.
