Dermatomes of upper limb - Study guides, Class notes & Summaries

Apical Ectodermal Ridge - ANSWER-Limbs arise from this and that governs limb formation No, because Myotomes and dermatomes are stretched down the developing limb so the torso is no longer present with the current spinal level -Exon the thorax the C4 dermatome meets the T2 dermatome - ANSWER-Will myotomes and dermatomes be in a contiguous sequence of spinal level nerves? Depressor muscles - ANSWER-Within a developing limb, the ventral rami pathways divide and the ventral divisions innerv...
