Anatomy Paper

Our bones, muscles and joints make up the musculoskeletal system. In order for our position to produce move they must work together. The central disgusted system and nerves send and receive the signal for movement. clappers provide support and structure for movement and mmuscles act by shortening the path amongst their ends, which be connected between several(predicate) bones, which allow the bones flex. Bones be loyal in compression as well as tension, so they are fit to anchor muscle ends at joints. So when your longing center tells you that you are thirsty, the signal for voluntary movement is initiated in the go cortex in the frontal lobe of the heading. The labour cortex works along with other parts of the brain to visualize movement such as the Basal Ganglia and the cerebellum. Axons so consort thru the thalamus down the cerebral peduncles and decussate in the medullary pyramids. Axons report down the spinal cord in the corticospinal tracts. The disappoint motor nerve cell synapses with the upper neurons in the adaxial nib 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 thus passed thru the nerves of the brachial plexus; either the radial nerve, average 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 or otund amounts of Na+ enters the neuron and d! epolarizes it. The membrane potential is over -55mV which Na+ then diffuses toward the trigger zone and opens up the voltage supply. Since there are large amounts of Na+ in the trigger zone, the rest of the voltage gates will open causing a voltage diversity 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
