Explanation Brachial is the nerve plexus that is the origin of almost all nerves belonging to the upper limb. It is divided into three cords that are made up of the following nerves: median nerve, ulnar nerve, axillary nerve, musculocutaneous nerve, and radial nerve. Brachial plexus is present partially in the neck and partially in the armpit. Major nerves in the upper limbs originate from the brachial plexus...

The nerve that innervates all extensor muscles of the arm and forearm. Introduction: Spinal cord is a mass of nerve cells that innervates the different parts of a human body. There are specific nerves for the innervation of a specific region. The nerve fiber may get branched in the target organ or structure of the human body. A particular nerve innervates the specific muscles of a region in the human body.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
