humerus, 2 fascial septa

Question 16

The deep fascia of the arm divides the arm into ___________ & ___________ compartments

Answer 16

Anterior and Posterior

-muscles, nerves, and arteries are compartmentalized via deep fascia

Question 17

The deep fascia of the arm has what clinical relevance?

Answer 17

Clinically relevant to compartmental syndromes

-increased pressure in compartment can affect circulation

Question 18
