Muscle Contraction & Excitation Muscle excitation takes place when there is a synaptic transmission and induction of an impulse. There are six steps that take place during muscle excitation. (1)The action potential travels down the somatic motor neuron axon reaching the synaptic bulb causing calcium ions to flow into the synaptic bulb. (2)The increase of calcium in the synaptic bulb causes the synaptic vesicles to undergo exocytosis. (Exocytosis a process that allows large molecule to leave

Compare and contrast cardiac and smooth muscle. In cardiac muscle‚ each heartbeat is triggered by the hearts own pacemaker cells‚ which initiate electrical discharge and when this reaches the contractile muscle cells (the cardiomyocytes)‚ they create an action potential which increases the concentration of calcium ions into the cell. Calcium ions play a key role in activating what is known as the contractile machinery – the actin and myosin filaments. The cardiac action potential‚ unlike other forms
