Cubital Fossa & Forearm

Muscles, bones, & Fascia

Movements of the Elbow & Forearm

  1. Describe the compartments of the forearm including the layers within each compartment.

Muscles of the Forearm

  1. Describe the attachments, actions, and innervation to the muscles of the forearm.

Injuries

Elbow

  1. What is medial and lateral epicondylitis?

Wrist

  1. What is Colles fracture? What is the dinner fork deformity associated with it?

Vasculature

Blood Supply

Forearm

  1. Describe arterial anastomosis around the elbow—what vessels contribute and how they
    communicate with one another. Why is this anastomosis important clinically?

Innervation

  1. 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.
  1. Trace the course of the median nerve, ulnar nerve, and radial nerve in the forearm and
    name their functions in the forearm, if any.
  1. Describe the movements of the elbow joint and the muscles responsible.
  1. 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.
  1. Palpate the anatomical snuffbox and locate the pulse of the radial artery.

Nerve Damage

  1. 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.
  1. What bone is compromised in a “fractured elbow”?
  1. A positive response from the biceps reflex confirms integrity of what nerve and what spinal
    cord levels?
  1. Describe the branching pattern of the radial and ulnar arteries as they course through the
    forearm.
  1. Why is the cubital fossa a common site for sampling and transfusion of blood?
