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 insertion is into the tuberosity of the radius (its posterior part; hence the biceps can act as a supinator) and the fascia of the forearm (and ultimately the ulna) by means of the bicipital aponeurosis (see fig. 9-4). The biceps and brachialis are the chief flexors of the forearm.
