Brain to Body Impulse Impact

When the body is dehydrated the brain sends messages through neurons to the body. The brain sends messages to the muscles telling the muscles to lift the glass using presynaptic neurons. The neurons communicate through electrical and chemical signs. These signals go through the body along the axon of the presynaptic neuron. The messages that are sent through this neuron are directed to the axon terminal of the presynaptic neuron. Chemical changes begin when the electrical signals makes the chemical changes cross the synapse affecting the postsynaptic cell. "The electrical impulse reaches the presynaptic axon terminal, membranous sacs called vesicles move toward the membrane of the axon terminal." (NIHC)

As the vesicles continue to move through the body they join the membrane and discharge what they carry into the synaptic space. Chemical compounds called neurotransmitters are held within the vesicles which are contained in the molecules. The nervous system using many of molecules to send signals throughout the body, neurotransmitters go across the synaptic cleft and stick to receptors. Electrical impulses at this point move away from the dendrite toward the cell body.

According to NIHC "after the neurotransmitter stimulates an electrical impulse in the postsynaptic neuron, it release from the receptors to back into the synaptic space." Retake pumps which are special proteins carry the neurotransmitter into the neuron once again. Motor coordination is used when lifting a glass of water. The central nervous system uses motor tasks to lift the glass of water. The brain acts in the space of rotation by the arm, wrist and other body parts movement which pick the state of manifold.

Essay on Brain to Body Impulse Path Assignment

The impulse transmission to muscle fibers takes place at the neuromuscular junctions. At the time when the nerve impulse terminal lets go of acetylcholine which then activates the acetylcholine receptor. According to Basel University, "(ACHR channels concentrated in the muscle membrane at the NMJ, thus eliciting muscle contraction." The muscles in the skeleton tighten together as they react to the electrical impulses in the motor nerves in the central nervous system.

In the central nervous system there are motor neurons are made to secrete Again and muscle fibers. Muscle contraction begins when actin and myosin filaments of the striated muscle glide over each other. As the fibers go over each other they decrease the size of the muscle fibers. The Myosin is seen when the actin sites filaments when are visible when the calcium ions attach to the troponin molecules. Due to this action bridges are made between actin and myosin. The ATP hydrolysis makes the head of the molecules change form and attach to the actin filament. More changes occur as ADP is released into the myosin heads; due to this the shape changes and allows mechanical energy where the filaments will slide over each other.

There are different muscles which are in use when lifting a glass of water. The muscles are made up of three long bones in the upper arm. The radius and the ulna of the forearm are just a few of the muscles which are used. According to the… [END OF PREVIEW] . . . READ MORE
