Neurotransmitters are the chemical molecules, which help in transfer of the signals from one neuron to another. Inside the neurons, the signals are transferred as electrical signals, but at junction of two neuron, which is known as synapse, the signals are transferred in chemical forms.

These neurotransmitters have a definite shape and are recognized by the receptors present in the receptor site of the succeeding neuron. The neurotransmitters from the synapse binds to the receptor site of the receiving neuron. binding of the neurotransmitter to the receptor causes excitation of the receiving neuron, which also known as postsynaptic neuron.

Hence, Like a key in a lock, the shape of the neurotransmitter must bind with the receptors of the receiving neuron.

Answer:

Seizure is an abnormal episode of motor, sensory, autonomic, or psychic activity resulting from a sudden, abnormal, uncontrolled electrical discharge from cerebral neurons.

Explanation:

Seizure is also formally known as an epileptic seizure which it's symptoms involve uncontrolled body movements mostly with every part of the body and loss of consciousness. Epileptic seizure lasts for the maximum of two minutes before the person returns to a normal state. Bladder control however, is usually absent at this stage. Epileptic seizure can be caused by either provocation or without provocation

In provocation, the causes are very low blood sugar and blood sodium, severe fever, brain infection or concussion. Without provocation; brain injury or tumor and a stroke.

When a seizure lasts more than a maximum of two minutes, it is declared an emergency but some seizures do last for about five minutes and it is regarded as normal. There hasn't been any form of cure for epileptic seizures but there are temporary treatments which can prevent frequent seizures.
