hey
i was trying to understand the mechanism for muscle contraction and in the revision guide it said that "myosin filaments have globular heads"-->

Is this just referring to the fact that its got a round head or is it also referring to the hydrophobic part in the centre and hydrophilic part on the outside ?

thank you ,would appreciate the help ;P

Both. Globular proteins have hydrophilic amino acids on the outside and hydrophobic amino acids on the inside and globular proteins usually have a roughly spherical structure.
