Larvae and Postlarvae. Planktonic larval life begins as the female lobster raises her abdomen and vigorously fans the pleopods to which the prelarvae are attached. This fanning breaks the cement attachment to the prelarvae and propels them upwards toward the water surface.
bicipital tuberosity. [bÄ«â²sipÂ·ÉdÂ·Él âtÃ¼bÂ·Éâ²rÃ¤sÂ·ÉdÂ·Ä] (anatomy) An eminence on the anterior inner aspect of the neck of the radius; the tendon of the biceps muscle is inserted here.
The deep muscles of the posterior compartment of the leg are the popliteus, tibialis posterior, flexor digitorum longus and flexor hallucis longus. The gastrocnemius calf muscle is the most superficial of the calf muscles. It inserts onto the heel bone via the Achilles tendon. The gastrocnemius muscle flexes the foot at the ankle joint â that is it acts to point the foot downwards by bending it at the ankle joint, such as when you stand on your toes. This action is known as plantar flexion. The gastrocnemius also flexes the leg at the knee joint.
