The urethra is the tube that drains urine from the bladder. The end of the urethra on the tip of the penis is called the meatus. Meatal stenosis is the narrowing of the meatus. On exam, the meatus appears nearly pin-point. Boys with meatal stenosis typically have a urinary stream that deflects upward or is prolonged. It is often a challenge for them to stand to urinate.
In tetrapods, the carpus is the sole cluster of bones in the wrist between the radius and ulna and the metacarpus. The bones of the carpus do not belong to individual fingers (or toes in quadrupeds), whereas those of the metacarpus do. The corresponding part of the foot is the tarsus. The carpal bones allow the wrist to move and rotate vertically.
