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 greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles-supraspinatus and infraspinatus.It is injured/fractured in a fall by either landing directly onto the side of your shoulder or landing with your arm outstretched.s greater tuberosity fractures are usually retracted posteriorly and superiorly, a closed reduction is difficult. If left in position, impingement will develop against the acromion, limiting elevation and external rotation of the shoulder.
