Movement of the lower arm bones in the direction indicated by the arrow results from the contraction of the biceps muscle. The biceps muscle is responsible for flexing the lower arm at the elbow joint, causing the forearm to move towards the upper arm. In this case, the biceps muscle shortens to pull on the forearm bones, creating the movement.


What are the two bones in the lower arm?

The two bones in the lower arm are the radius and the ulna. The radius is located on the thumb side of the forearm, while the ulna is positioned on the pinky side. These two bones run parallel to each other and play a crucial role in the movement and stability of the forearm and wrist.


Names of human arm bones?

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.
