The arrows in D and J indicate the tissue breakdown processes the separate the fingers and toes kidney depression symptoms cheap 300 mg eskalith amex. As the limbs elongate depression nutrition discount 300mg eskalith mastercard, mesenchymal models of the bones are formed by cellular aggregations (see anxiety lightheadedness all day order 300mg eskalith mastercard. Osteogenesis of long bones begins in the seventh week from primary ossification centers in the middle of the cartilaginous models of the long bones mood disorder odd purchase eskalith paypal. Ossification centers are present in all long bones by the 12th week (see Chapter 14). Ossification of the carpal (wrist) bones only begins during the first year after birth. From the dermomyotome regions of the somites, myogenic precursor cells also migrate into the limb buds and later differentiate into myoblasts, precursors of muscle cells. As the long bones form, the myoblasts aggregate and form a large muscle mass in each limb bud (see. In general, this muscle mass separates into dorsal (extensor) and ventral (flexor) components. The mesenchyme in the limb bud also gives rise to ligaments and blood vessels (see. The cervical and lumbosacral myotomes contribute to the muscles of the pectoral and pelvic girdles, respectively. Originally the flexor aspect of the limbs is ventral and the extensor aspect dorsal, and the preaxial and postaxial borders are cranial and caudal, respectively (see. The developing upper and lower limbs rotate in opposite directions and to different degrees. The lower limbs rotate medially through almost 90 degrees; thus, the future knees come to face ventrally and the extensor muscles lie on the anterior aspect of the lower limb. Developmentally, the radius and the tibia are homologous bones, as are the ulna and fibula, just as the thumb and great toe are homologous digits. Synovial joints appear at the beginning of the fetal period, coinciding with functional differentiation of the limb muscles and their innervation. Cutaneous Innervation of Limbs There is a strong relationship between the growth and rotation of the limbs and the cutaneous segmental nerve supply of the limbs. Motor axons arising from the spinal cord enter the limb buds during the fifth week and grow into the dorsal and ventral muscle masses. Sensory axons enter the limb buds after the motor axons and use them for guidance. Neural crest cells, the precursors of Schwann cells, surround the motor and sensory nerve fibers in the limbs and form the neurilemmal and myelin sheaths (see Chapter 17). During the fifth week, peripheral nerves grow from the developing limb plexuses (brachial and lumbosacral) into the mesenchyme of the limb. The spinal nerves are distributed in segmental bands, supplying both dorsal and ventral surfaces of the limb. A dermatome is the area of skin supplied by a single spinal nerve and its spinal ganglion; however, cutaneous nerve areas and dermatomes show considerable overlapping. As the limbs elongate, the cutaneous distribution of the spinal nerves migrates along the limbs and no longer reaches the surface in the distal part of the limbs. Although the original dermatomal pattern changes during growth of the limbs, an orderly sequence of distribution can still be recognized in the adult (see. In the upper limb, observe that the areas supplied by C5 and C6 adjoin the areas supplied by T2, T1, and C8, but the overlap between them is minimal at the ventral axial line. Dorsal (A) and plantar (B) views of the right foot of a human embryo, Carnegie stage 19 (approximately 48 days). The toe buds (arrowheads in A) and the heel cushion and metatarsal tactile elevation (asterisks in B) have just appeared. Dorsal (C) and distal (D) views of the right foot of human embryos, Carnegie stage 22 (approximately 55 days). Note the dorsiflexion of the metatarsus and toes (C) as well as the thickened heel cushion (D). C and D, Paraffin sections of the tarsus and metatarsus of a young human fetus, stained with hematoxylin and eosin. The separation of the interosseous muscles (im) and short flexor muscles of the big toe (sfh) is clearly seen. The plantar crossing (cr) of the tendons of the long flexors of the digits and hallux is shown in D. If the dorsal root supplying the area is cut, the dermatomal patterns indicate that there may be a slight deficit in the area indicated. Because there is overlapping of dermatomes, a particular area of skin is not exclusively innervated by a single segmental nerve. The limb dermatomes may be traced progressively down the lateral aspect of the upper limb and back up its medial aspect. A comparable distribution of dermatomes occurs in the lower limbs, which may be traced down the ventral aspect and then up the dorsal aspect of the lower limbs. When the limbs descend, they carry their nerves with them; this explains the oblique course of the nerves arising from the brachial and lumbosacral plexuses. All regions of the limbs are apparent and the digits of the hands and feet are separated. The primordial vascular pattern consists of a primary axial artery and its branches (see. The vascular patterns change as the limbs develop, chiefly by angiogenesis (sprouting from existing vessels). The primary axial artery becomes the brachial artery in the arm and the common interosseous artery in the forearm, which has anterior and posterior interosseous branches. As the digits (fingers) form, the marginal sinus breaks up and the final venous pattern, represented by the basilic and cephalic veins and their tributaries, develops. In the thigh, the primary axial artery is represented by the deep artery of the thigh (Latin, profunda femoris artery). In the leg, the primary axial artery is represented by the anterior and posterior tibial arteries. Although these anomalies are usually of no serious medical consequence, they may serve as indicators of more serious anomalies and may be part of a recognizable pattern of birth defects. A, Approximately 48 days, showing the limbs extending ventrally and the hand and footplates facing each other. B, Approximately 51 days, showing the upper limbs bent at the elbows and the hands curved over the thorax. ure 1610 Illustrations of the development of the dermatomal patterns of the limbs. B and E, Similar views later in the fifth week showing the modified arrangement of dermatomes. The primordial dermatomal pattern has disappeared but an orderly sequence of dermatomes can still be recognized. F, Note that most of the original ventral surface of the lower limb lies on the back of the adult limb. This results from the medial rotation of the lower limb that occurs toward the end of the embryonic period. In the upper limb, the ventral axial line extends along the anterior surface of the arm and forearm. In the lower limb, the ventral axial line extends along the medial side of the thigh and knee to the posteromedial aspect of the leg to the heel. This statement is based on clinical studies of infants exposed to thalidomide, a potent human teratogen, during the embryonic period. Exposure to this teratogen before day 33 may cause severe limb defects, such as amelia, the absence of limbs. Consequently, a teratogen that could cause amelia of the limbs or parts of them must act before 36 days, the end of the critical period of limb development. Many severe limb anomalies occurred from 1957 to 1962 as a result of maternal ingestion of thalidomide. This drug, widely used as a sedative and antinauseant, was withdrawn from the market in December 1961. Because thalidomide is now used for the treatment of leprosy and several other disorders, it must be emphasized that thalidomide is absolutely contraindicated in women of childbearing age. Several unrelated congenital anomalies of the lower limb were found to be associated with a similar aberrant arterial pattern, which might be of some importance in the pathogenesis of these defects. A, Sketch of the primordial cardiovascular system in a 4 week embryo, approximately 26 days.
