"As to the muscles, there is a short flexor, a short extensor, and a peronaeus longus, while the tendons of the long flexors of the great toe and of the other toes are united together and into an accessory fleshy bundle. "The hind-limb of the Gorilla, therefore, ends in a true foot with a very movable great toe.
It forms the fleshy mass on the back of the arm, its use being to draw the flexed forearm into a right line. On the back and outside of the forearm are the extensors, which straighten the wrist, the hand, and the fingers. On the front and inside of the forearm are the flexors, which bend the hand, the wrist, and the fingers.
Again, the tendons of the long flexor of the toes, and of the long flexor of the great toe, when they reach the sole of the foot, do not remain distinct from one another, as the flexors in the palm of the hand do, but they become united and commingled in a very curious manner while their united tendons receive an accessory muscle connected with the heel-bone.
The extensor tendons, because of the nature of their function, are very seldom strained; they are often bruised and occasionally divided, but unlike this condition in the flexors, tendinitis of the extensors is of rare occurrence.
This, he declares, is a purely mechanical process due to heat and pressure, the wonderful effects of which may be seen in Papin's recently invented 'digester. That the stomach is fully able to comminute the food may be proved by the following calculation. Borelli estimates the power of the flexors of the thumb at 3720 pounds, their average weight being 122 grains.
The structures which are usually considered as true flexors of the carpus are a group of three muscles, which have separate heads of origin and different points of tendinous insertion. This muscle is the smaller of the three and is not usually divided in doing carpal tenotomy. The other blends with the posterior annular ligament of the carpus. Etiology and Occurrence.
Daily injections for three, four or five days, are not harmful and will control infection in many instances. Thecitis and Bursitis. Etiology and Occurrence. The thecae and bursae of the leg are several in number. In the carpal region, the flexors of the phalanges are contained together in the carpal sheath, and this is the principal theca in the carpal region.
Movements often pass to fixed attitudes and postures of limbs or body, disturbing the normal balance between flexors and extensors, the significance of which as nerve signs or exponents of habitual brain states and tensions Warner has so admirably shown. Abundance and vigor of automatic movements are desirable, and even a considerable degree of restlessness is a good sign in young children.
It seems a matter of question whether one would be likely to make love or evince sorrow any more successfully by keeping in mind all the while the detailed catalogue of his flexors and extensors, and contracting and relaxing No. 1, 2, or 3, according to rule.
However, in most instances, the practitioner's attention is not directed to typical and uncomplicated cases, but to subacute or chronic inflammations which are often attended with contraction of the tendinous parts of the carpal flexors, and in such cases carpitis is present.
