Nerve impulse travel through synapse with the help of

Options

A. Acetylcholine and sympathetin
B. Choline and acetylcholine
C. Adrenaline and noradrenaline
D. None of the above

Answer

To answer the question "Nerve impulse travels through synapse with the help of," we can break down the process step by step:

### Step 1: Understanding Synapse
A synapse is the junction between two neurons where the axon terminal of one neuron meets the dendrites of another neuron. This is where the transmission of nerve impulses occurs.

**Hint:** Remember that the synapse is the connection point between two neurons.

### Step 2: Arrival of Nerve Impulse
When a nerve impulse reaches the end of the axon (axon terminal) of the first neuron, it triggers a series of events that lead to the transmission of the impulse to the next neuron.

**Hint:** Think about what happens at the end of the axon when the impulse arrives.

### Step 3: Release of Neurotransmitters
Upon reaching the axon terminal, the nerve impulse causes the release of neurotransmitters. These are chemical messengers that facilitate communication between neurons.

**Hint:** Identify the role of neurotransmitters in the transmission of signals.

### Step 4: Travel Across the Synapse
The released neurotransmitters travel across the synaptic cleft (the gap between the two neurons) to bind to the receptors on the dendrites of the receiving neuron.

**Hint:** Consider how neurotransmitters move from one neuron to another.

### Step 5: Binding and Transmission
Once the neurotransmitters bind to the receptors on the dendrites of the next neuron, they trigger a response that allows the nerve impulse to continue traveling through the receiving neuron.

**Hint:** Think about what happens when neurotransmitters bind to the receptors.

### Step 6: Identifying the Chemicals
In this context, the key neurotransmitters involved in the transmission of nerve impulses include Acetylcholine, Adrenaline, and Noradrenaline. However, the specific answer to the question is that nerve impulses travel through synapses with the help of **Acetylcholine** primarily.

**Hint:** Focus on the most common neurotransmitter associated with synaptic transmission.

### Final Answer
The correct answer is **Acetylcholine**.
