Cubital Fossa & Forearm - Coggle Diagram
Cubital Fossa & Forearm
Muscles, bones, & Fascia
-
- Identify the function(s) and attachments of the flexor retinaculum. What major tendons
pass beneath this structure? Nerves? Do the same regarding the extensor retinaculum.
Injuries
Elbow
- What is medial and lateral epicondylitis?
- What bone is compromised in a “fractured elbow”?
Wrist
- What is Colles fracture? What is the dinner fork deformity associated with it?
Vasculature
Blood Supply
Forearm
- Describe arterial anastomosis around the elbow—what vessels contribute and how they
communicate with one another. Why is this anastomosis important clinically?
- Describe the branching pattern of the radial and ulnar arteries as they course through the
forearm.
- Palpate the anatomical snuffbox and locate the pulse of the radial artery.
- Why is the cubital fossa a common site for sampling and transfusion of blood?
Innervation
- Draw the general pattern of cutaneous distribution to the surfaces of the forearm, relating
them to major nerves and/or cords of the brachial plexus.
- Trace the course of the median nerve, ulnar nerve, and radial nerve in the forearm and
name their functions in the forearm, if any.
Nerve Damage
- Explain how you would clinically test the axillary, musculocutaneous, radial & ulnar nerves
for loss of function. Do the same for thumb testing of radial, median & ulnar nerves.
- A positive response from the biceps reflex confirms integrity of what nerve and what spinal
cord levels?
