Important Questions on Neural Control and Coordination

EASY
Neurotransmitter released at the neuromuscular junction of a voluntary muscles is:
EASY
Each neuron has a cell body, axon, and dendrites. The dendrites are the protoplasmic extensions of the nerve cell. The axodendritic type of chemical synapse is formed by the association between the axon terminal of the pre-synaptic neuron and the dendrites of a post-synaptic neuron. The action potential causes the fusion of the synaptic vesicle to release the neurotransmitters for neurotransmission. Select the correct option from the following.
MEDIUM
When 'A' stands for Axon, 'D' for Dendrites, 'S' for Synapse and 'B' for Cell body, a typical sequence of structures between a receptor and an efferent is
EASY
The transport of which neutrotransmitter is interfered by cocaine?
EASY
Action potential in neurons is generated by a rapid influx of
MEDIUM

Assertion (A): Impulse transmission across electrical synapse is always faster than that of chemical synapse.

Reason (R): In electrical synapse, pre and post synaptic membranes are in very close proximity and have links called gap functions.

The correct option among the following is

MEDIUM

Identify A, B, C and D in the following graph regarding nerve impulse transmission.

EASY
Stimulation of a muscle fiber by a motor neuron occurs at:
EASY

Assertion (A): In myelinated nerve fibres, action potentials are conducted at a faster rate.

Reason (R): The myelin present between nodes of Ranvier has concentrated Na and K voltage-gated channels.

EASY

All the following structures are found in an electrical synapse except

MEDIUM
Four healthy friends in their thirties had an accident and got injuried. It resulted in damage and death of a few cells in their body. Which of the cells are least likely to be replaced by new cells?
MEDIUM

The given figure shows the structure of a neuron. Select the option that correctly identifies the parts labelled as A to E.

MEDIUM
What used to be described as Nissl granules in a nerve cell are now identified as mitochondria.
EASY

Where are Nissl's granules found and what is their nature?

EASY
Which of the following is an incorrect statement with respect to the neuron?
EASY
Nissl granules are found in ____ I _____ and _____ II _____, but are absent in _____ III _____. Choose the correct option.
