Aspirated body from the space

Four spheres are linked together confining the blood in them. This aspiration was performed after injection of approximately 1.8 ml of the anesthetic solution. The transparent gel‐like material seems to be an amorphous ground substance which fills the loose connective tissue in the pterygomandibular space.

A strong bloody flow by aspiration

The source of the blood is not from blood vessel but from the space since the blood is surrounded by the semitransparent gel‐like fluid (arrow).
