Question: Which of the following statement is correct?
Options:
A) Electrical synapses are more common in our neural system than chemical synapses.
B) The new potential in post-synaptic neuron may be either excitatory or inhibitory.
C) Hypothalamus is the major coordination centre for sensory and motor signaling.
D) The tracts of nerve fibres that connect two cerebral hemispheres are called corpora bigemina.
Show Answer
Answer:
Correct Answer: B
Solution:
[b] An electrical synapse is a mechanical and electrically conductive link between two adjoining neurons that is formed at a narrow gap between the pre- and postsynaptic neurons known as a gap junction.
Electrical synapses are rare in our neural system.
Hypothalamus contains a number of centres which control body temperature, urge for eating and drinking.
It also contains several groups of neurosecretory cells which secretes hormone called hypothalamic hormones.
Thalamus is a major coordinating centre for sensory and motor signalling.
The tracts of nerve fibres that connect two cerebral hemispheres are called corpus callosum.
