    membrane of the neuron is made. The generation of an impulse is dependent on the charge difference of the inside and outside of the cell. The neuron changes to a positive charge creating a reversal of the electric potential at the cell membrane. The change is known as an action potential. It goes through the axon membrane at a speed of hundreds miles per hour‚ enabling a neuron to fire many impulses per second. The

    Muscle Cell at rest: As the muscle cell is at rest it has a resting potential of -90mV.  The K+ is all located inside the cell‚ the Na+ is located outside  of the cell and the Ca2+ is located inside the sarcoplasmic reticulum.  All leak channels and pumps are closed at this point. Muscle Cell stimulated by Acetylcholine: A motor neuron releases Acetylcholine which diffuses toward the  muscle cell across the neuromuscular junction. As the Acetylcholine  binds to a receptor on the muscle

    When substances like acetylcholine and norepinephrine are released in the body‚ they tend to bind to receptors‚ tissues and neurons. These neurotransmitters transfer signals throughout the nervous system and stimulates action potentials in the postganglionic neurons. Receptors found on the ANS and PNS includes the cholinergic receptors‚ which consists of all sympathetic and parasympathetic preganglionic‚ sympathetic postganglionic and all parasympathetic postganglionic neurons. The cholinergic receptors

    Membrane Potentials Dr Penny Murphy Objectives The student should be able to: Describe the basic building blocks of the central nervous system. Explain what a “resting membrane potential” (RMP) is and how it is generated. Include the characteristics of the phospholipid bilayer‚ leak membrane channels and the diffusion of K+ ions‚ and the role of the Na+/K+ ATPase pump. Explain how and why increasing the permeability of the membrane to Na+ ions will affect the membrane potential. Describe

    from its receptor. Once sodium gates close it initiates K+ gates to open. K+ rushes out of the cell this and once repolarized the gates closes by the use of a pump and return to a resting state. ATP powers the Ca++ active transport pumps. The action potential spreads away from the end plate in all directions and depolarizes the T-tubules and dips down into the SR and depolarizes it. Calcium gates on the SR return open and allows calcium to rush out into the sarcoplasm. Calcium gates close‚ when a

    The series of events prompting muscle contraction is started some place in the central nervous system‚ either as willful action from the brain or as reflex action from the spinal cord. Beginning with depolarization at the neuromuscular junction‚ the depolarizing impulse discharges acetylcholine from the nerve ending. Which then diffuses over the neuromuscular junction (a chemical synapse formed by the contact between a motor neuron and a muscle fiber). At the motor end plate‚ the acetylcholine joins
