Radius and Ulna Anatomy and Physiology: Forearm Bones
The forearm bones consist of the radius and ulna. In this anatomy lesson, I'll cover the basic anatomy of these two forearm bones, which are classified as long bones in the appendicular skeleton.
The radius bone is always on the thumb side. The ulna is under the radius when you hold your arm out as if you were going to shake someone's hand.
Here are the major structures on the radius, which are covered in the video:
• Head
• Proximal Radioulnar Joint
• Neck
• Radial Tuberosity
• Styloid Process of Radius
• Ulnar Notch
• Distal Radioulnar Joint
Here are the major structures on the ulna, which are covered in the video:
• Olecranon Process
• Coronoid Process
• Trochlear Notch
• Radial Notch
• Head of Ulna
• Styloid Process of Ulna

Excellent 🌹
I learned a trick in anatomy. You can make a small r with your radius (thumb) and you can make a u with your pinky. Great review. Especially where the muscles connect. That's always so hard to remember!

Omg thank you
I am totally dating myself with this memory trick, but the ninja turtles said radical dude while giving a thumbs up. So I always remember radical radius.

I love that, that's actually a good one.
The range of motion this appendage is capable of is shear genius of design. The eight bones of the wrist attached directly in coordination with this structural system. Our skeleton is a fascinating construction.
I learned a lot from you videos and the free quizzes are great, thank you so much.
Very good yet again; hope you guys keep it up; great teaching.
You and your beautiful wife(my namesake) are amazing instructors. I'm a Registered Practical Nurse in Ontario. I am planning to take Nephrology Course, with the hope of building my career as a Dialysis Nurse. Any advise on becoming Dialysis Nurse? Thank you.🙏🏻🙏🏻
Ulna is shorter than Radius. Ulna is on the pinky side, which is the shortest finger.
Amazing. You and your beautiful wife are wonderful instructors. Thank you.
Radius is connected to the thumb. ulna is slightly longey than the radius.
Great video sir. I really appreciate the detail explanation used for radios, ulna and the connection with the humerus bone
Thanks alot it really helped me so much
Thank you for this! :)
what a great speaking voice
Another good 1
I was so useful to me
great video! helped a lot
Good job
thanks a lot
Interesting
I also think radius is a fat word like your thumb being fat, ulna is a skinny word so it’s your pinky
well explained
