Anatomy Paper

Our bones, muscles and joints make up the musculoskeletal system. In order for our embody to produce move they must work together. The central disgusted system and nerves send and receive the signal for movement. bones provide support and structure for movement and mmuscles act by shortening the path amongst their ends, which are connected between varied bones, which allow the bones flex. Bones are loyal in compression as well as tension, so they are fit to anchor muscle ends at joints. So when your desire center tells you that you are thirsty, the signal for voluntary movement is initiated in the go mantle in the frontal lobe of the heading. The get cortex works along with other parts of the brain to stick out movement such as the Basal Ganglia and the cerebellum. Axons so graze thru the thalamus down the cerebral peduncles and decussate in the medullary pyramids. Axons appease down the spinal cord in the corticospinal tracts. The disappoint motor n erve cell synapses with the upper nerve cells in the dorsoventral neb of the spinal cord. Since the thirst center is sending the signal that you are thirsty; The nerve impulse will exit thru the ventral root into the spinal nerve proper and indeed thru the brachial plexus around the cervical en volumedment/ C7 area.

Signal is so passed thru the nerves of the brachial plexus; either the radial nerve, medial nerve or the ulnar nerve to stimulate muscles in the arms and hands to reach for a glass or water. The nerve impulse causes a local budge in membrane potential. Ligand gate open and bombastic amounts of Na+ enters the neuron and depolarizes it! . The membrane potential is over -55mV which Na+ then diffuses toward the trigger zone and opens up the voltage furnish. Since there are large amounts of Na+ in the trigger zone, the rest of the voltage gates will open causing a voltage careen and the nerve will fire. Once the voltage change reaches the synaptic knobs at the end of the axon, atomic number 20 gates open and calcium enters the...If you want to get a full essay, order it on our website: OrderCustomPaper.com
