The orbicularis oculi has fibers that run in circles around the eyes; it allows you to close your eyes, squint, blink, and wink. Flexion and Extension of Fingers: Formation of White Blood Cells and Platelets Like erythrocyte production, the formation of leukocytes and platelets is stimulated by hormones.
The hormone thrombopoeitin accelerates the production of platelets, but little is known about how that process is regulated. Entrapment of Median N. Injury to the lining of vessels exposes collage fibers; platelets adhere to the damaged site and platelet plug forms.

The Pisiform bone, distally, acts as a lever in allow the flexor carpi ulnaris to flex the fingers more strongly. The larger, thick filaments, also called myosin filaments, are made mostly of bundled molecules of the protein myosin, but they also contain ATPase enzymes, which split ATP to generate the power for muscle contraction.
Within 2 days of release, they have rejected the remaining ER and have become fully functioning erythrocytes; the entire developmental process from hemocystoblast to mature RBC takes 3 to 5 days.
It holds it down, so that the skin on the palm is tight and hairless.
