Which of the following statements about transmission of nerveimpulse is incorrect?(a) Nerve impulse travels from dendritic end towards axonal end(b) At the dendritic end electrical impulses bring about the releaseof some chemicals which generate an electrical impulse at theaxonal end of another neuron(c) The chemicals released from the axonal end of one neuron crossthe synapse and generate a similar electrical impulse in adendrite of another neuron(d) A neuron transmits electrical impulses not only to anotherneuron but also to muscle and gland cells

Read the following statements about the transmission of nerve impulse and select the correct ones. (i) In a neuron, nerve impulse travels from the axonal end to the dendritic end as:Axonal end → Axon → Cell body → Dendritic end.(ii) The chemicals released from the axonal end of one neuron cross the synapse and generate a similar electrical impulse in the dendrite of another neuron.(iii) A neuron transmits the nerve impulses not only to another neuron but also to the muscle cells and gland cells.(iv) The neurotransmitter released at the post-synaptic membrane, diffuses across the synapse and comes into contact with the chemoreceptor sites in the pre-synaptic membrane.

Signals are transmitted from one neuron to the next neuron, by molecules. These statements are about this process: 1. Transmitter molecules are formed in the receptors. 2. The signal is transmitted across the synapse by osmosis. 3. Transmitter molecules are automatically released once the signal has been transmitted across the synapse. 4. The release of transmitter molecules is triggered by an impulse. 5. The signal is transmitted across the synapse by diffusion. Which of the above statements are correct? A) 1 and 2 B) 1 and 3 C) 2 and 4 D) 3 and 4 E) 4 and 5

Which of the following statements concerning a chemical synapse is true?Question 25Select one:a.Neurotransmitter is released in response to an action potential arriving at the axon hillock.b.Neurotransmitter is actively transported across the synaptic cleft.c.Neurotransmitter binds to its receptors on the postsynaptic membrane.d.The synapse consists of a presynaptic dendrite, a postsynaptic cell and an interstitial space between them (known as the synaptic cleft).e.The synapse consists of a presynaptic dendrite, a postsynaptic neuron and an interstitial space between them (known as the presynaptic cleft).
