What's the difference between arrowhead and sagittate?
Arrowhead
Definition:
(n.) The head of an arrow.
(n.) An aquatic plant of the genus Sagittaria, esp. S. sagittifolia, -- named from the shape of the leaves.

(15) Since these filaments bind rabbit myosin subfrafment-1 to form arrowhead complexes, we conclude that they contain actin.
(16) In addition to the arrowheads, thin whiskers, 700-1200 A in length and 20 A in width, attached to the arm of the arrowheads have been demonstrated.
(17) Myosin-II binds to actin filaments, forming periodic arrowhead-shaped complexes, but its Mg2+ ATPase activity is activated only 50% or less by actin.
(18) Microfilament polarity is shown by S1 arrowheads pointing away from the microvillous tip to the cell body.
(19) While city-dwellers and tourists might not think twice before knocking back an Arrowhead – Nestlé’s premier California still water brand – or a Crystal Geyser, residents near the affected springs and watersheds tend to be more vocal, because every drop Nestlé takes is one drop less for their own use and for the local flora and fauna.
(20) In the range of micro = 0.3-0.1, the LMM whiskers merge into smooth filaments which are arranged alternatingly with arrowhead-bearing filaments.
Sagittate
Definition:
(a.) Shaped like an arrowhead; triangular, with the two basal angles prolonged downward.
Example Sentences:
(1) The relapse was 80% in the sagittal plane, 70% in the transverse plane, and 12% in the vertical plane.

(6) The symptoms were thought to be due to transient impairment of blood flow in the superior sagittal sinus.
(7) Study 1 assessed the effects of roentgenogram quality, raters, and seven measurement methods on the consistency and accuracy of evaluating translations in the sagittal plane.
(8) Correlation with high-resolution computed tomography in two patients indicated that this opacity represented a sagittal orientation of the anterior minor fissure, with resultant inferomedial curving of the right upper lobe of the lung along the right border of the heart.
(9) We conclude that during acute moderate hypoxemia reduction in CVR can occur independently from increases in brain ECF, cisternal CSF, and arterial and sagittal venous blood [H+] and PCO2.
(10) Considerable spontaneous correction of deformity can be expected in the younger child (under age 10 years), but one should be aware that sagittal plane and rotational malalignment of the metatarsal heads may cause significant problems.
(11) The malformations over the surface drain into the superior sagittal sinus.
