Next, the blastocyst travels up into the uterus. Now, it's time for implantation -- the process where the fertilized egg has become attached (or implanted) into the uterine wall. Implantation is the first âstepâ that triggers your body to start producing the hCG, (also known as the pregnancy hormone).
see laryngeal chondritis. arytenoid cartilage. one of the paired laryngeal cartilages in the dorsal part of the larynx that provides attachment for the muscles that adduct and abduct the vocal cords. The cartilages form the dorsal boundary of the rima glottis, the vocal cords the ventral boundary. arytenoid chondritis.
Paired Cartilages. The other six cartilages of your larynx-two arytenoids, two cuneiforms, and two corniculates-are involved in suspending, moving, and protecting your vocal cords. The largest and most important of the paired cartilages are the arytenoids, which are shaped like two three-sided pyramids.he opening between the vocal cords is called the rima glottidis, or simply the glottis. The arytenoid cartilages, which anchor the vocal cords at the rear of your larynx, play a major role in tightening and moving your vocal cords in and out to vary the pitch of the sounds you make.
