The ship certainly would not have survived, but it might have kept the passengers alive a lot longer. The damage to the compartments was comparatively minor, but all that mattered was that they were no longer water-tight. It's like a balloon: it doesn't matter how hard you pop it.

In males, it arises from the medial aspect of the ischial tuberosity and more anteriorly, from the ischial ramus.It inserts into the aponeurosis over the medial and lateral sides of the crus penis.It action is to facilitate the maintainance of an erection.n females, ischiocavernosus has a similar origin but it inserts into the crura of the clitoris. Its function is similar: to retard venous return so erecting the clitoris. Ischiocavernosus is innervated by the perineal branch of the pudendal nerve (S2-4).
The muscle inserts into the base of the first metatarsal bone in the foot, located just behind the big toe. It also inserts to the medial and inferior surfaces of the medial cuneiform tarsal. The tibialis anterior muscle helps with dorsiflexion, which is the action of pulling the foot toward the shin.It also inverts (tilts inward) the foot at the subtalar and midtarsal joints and holds up the medial longitudinal arch of the foot.n general, muscles of this compartment help to flex the foot in an upward direction at the ankle and also extend the toes. The tibialis anterior muscle emerges from the upper lateral (outer) surface of the tibia, or shinbone, and from the interosseous membrane.
