Ossification of the cartilages is known by grasping the free borders with the fingers and attempting their flexion; the rigid inflexible ossified cartilage is thus easily recognized. Lameness during weight-bearing occurs in the majority of cases at some time.
Cut off the wish-bone in a slanting direction from the front of the breast-bone down to the shoulder on each side. Cut through the cartilage between the end of the collar-bone and the breast. Cut between the end of the shoulder-blade and the back down toward the wing-joint, turn the blade over toward the neck, and cut through the joint.
Every Vertebrate has a backbone; every Vertebrate has a bony arch above that backbone and a bony arch below it, forming two cavities, no matter whether these arches be of hard bone, or of cartilage, or even of a softer substance; every Vertebrate has the brain, the spinal marrow or spinal cord, and the organs of the senses in the upper cavity, and the organs of digestion, respiration, circulation, and reproduction in the lower one; every Vertebrate has four locomotive appendages built of the same bones and bearing the same relation to the rest of the organization, whether they be called pectoral and ventral fins, or legs, or wings and legs, or arms and legs.
The Vertebrates form a direct contrast to this. In these alone a solid internal skeleton is developed, of cartilage or bone, to which the muscles are attached. This bony skeleton is a complex lever apparatus, or PASSIVE apparatus of movement. Its rigid parts, the arms of the levers, or the bones, are brought together by the actively mobile muscles, as if by drawing-ropes.
And, naturally, one is not to expect resolution in cases where there exist erosion and ossification of cartilage where crepitation is discernible. Paralysis of the Hind Leg. Aside from paraplegic conditions due to disease of the cord or the lumbosacral plexus, and monoplegic affections resultant from disturbances of this plexus, paralysis of certain nerves are occasionally encountered. Anatomy.
The cartilaginous pads between the vertebræ permit, by their elasticity, of a slight bending of the column in different directions. These movements are caused, not by one bone gliding over another, but by compressions and extensions of the cartilage. Between the vertebræ in the back of the spinal column, however, there is a slight movement of the bone surfaces upon one another.
When nature does a trick like this, she does it thoroughly, for it has been noticed but more especially in the case of twins the likeness includes the voice, or at least its timbre, the thyroid cartilage and vocal chords following the mysterious law that rules the duplication.
The stone out of which the beautiful head is cut is not polished, but wrought so finely as to almost imitate the texture of the skin. It is decidedly a good looking face. The nostrils are most delicately chiseled, and the cartilage pierced; the eyes are open, and clearly marked. On the right cheek is his totem, a fish traced in exceedingly small cross bars.
At the lower spine are two more ribs, extended horizontally when open, jointed again to the hips, and long enough to meet the joint on the contrary side cross the belly; and from the hip-joint, which is on the outermost edge of the hip-bone, runs a pliable cartilage quite down the outside of the thigh and leg to the ankle; from which there branch out divers other ribs horizontally also when open, but when closed, they encompass the whole thigh and leg, rolling inwards cross the back of the leg and thigh till they reach and just cover the cartilage.
As it was, it narrowly escaped a fracture and, for several weeks afterward, it felt as if powdered glass had been substituted for cartilage between the vertebrae. I did not lose consciousness even for a second, and the demoniacal dread, which had possessed me from June, 1894, until this fall to earth just six years later, was dispelled the instant I struck the ground.
