Agonist - muscle contacting during movement amphiarthrosis - joint with little movement annulus fibrosus - outer tough fibrocartilage of intervertebral discs antagonist - relaxes during joint movement Bursa - fluid filled pads found where rubbing occurs dense bodies - in smooth muscle cells thin filaments are attached to diarthrosis - joint with free movement endomysium - covers each muscle cell epimysium - covers the entire skeletal muscle eversion - soles turn out extenders - back of...

Transverse/ Cross - ️️A plane that extends from left to right and from dorsal to ventral, giving cranial and caudal portions midsaggital - ️️a plane that extends from cranial to caudal passing through the midline to divide the body into right and left halves Caudal - ️️The tail end Ventral - ️️The belly side Dorsal - ️️The back side Superior - ️️Upper portion, or which that is above (Think of being super and being above of everyone else) Inferior - ️️The lowe...
