Spinal Nerves
...  When any of the nerves supplying the muscles experience injury, you will observe a loss of power in the supplied area, although the sensation is still present. Function The spinal nerves cause the innervations in different parts of the body. Let's say, for the cervical nerves, they supply the muscles and skin of the neck and the shoulder. If you experience pain in the area, you must consider a  ...

Peripheral Ganglia
...  them in the abdomen, thorax, stomach, spleen, and liver kidney along the pelvis area, which act as the target organs. The genital organs and small intestines are also involved and they respond to innervations initiated by the postganglionic neurons. The peripheral ganglia are responsible in coordinating innervations coming from other organs and cells to the central nervous system. Protection  ...

Parasympathetic Division
...  effects of the action of the parasympathetic division are opposite to that of sympathetic, and the process is “rest and digest” instead of “fight or flight.” Preganglionic innervations An innervation is the stimulation of nerves or muscles in the body to affect specified responses. Aside from the sympathetic division, the parasympathetic division is also involved in  ...

Dual Innervation
...  homeostatic ability of the body, which involves the internal balance of the human system, is dependent on dual innervations. Without this system, the body will not function properly. How do dual innervations work and what is their significance in the body? Dual innervations These are innervations affected by two systems, the parasympathetic and sympathetic nerve systems. They are both present  ...

Brachial Nerve Plexus
...  reach their final destination. The three major roots that constitute the brachial plexus are the ones responsible for creating the five major nerves that serve the required coetaneous and muscular innervations for the upper extremities to function. The five most essential nerves of the upper extremities include the ulna nerve, the radial nerve, the axillary nerve, the median nerve, and the  ...
