Question

Which of the following terms is not correctly matched with its feature?
A. Efferent neurons - Carries signals from CNS to the effector.
B. Axon terminal - Possess neurotransmitter-containing vesicles.
C. Limbic system - Along with the hypothalamus, it is involved in the regulation of sexual behaviour, expression of emotional reactions, and motivations.
D. Associations areas - Present in the cerebellum and responsible for functions like intersensory associations, memory, and communications.

Answer 1

Hint:
Neurons are known as nerve cells and transmit information in the form of electrical impulses. They are microscopic in nature and constituted of three major parts: cyton, dendrites, and axon.

Complete answer:
The Axon terminal is the button-like ending of axons with the help of this axon makes synaptic contact with other effector nerve cells. The synaptic vesicles are present inside the axon terminals that contain neurotransmitters. They get attached to the pre-synaptic membrane and release the neurotransmitter in the synaptic cleft.
An efferent neuron or motor neuron carries impulses to effector organs from CNS. The limbic system is the part of the brain and takes part in our behavioral and emotional responses. This system along with the hypothalamus involved in the regulation of sexual behaviour, expression of emotional reactions, and motivations.
Associations areas are the region of the cerebral cortex of the brain. It is connected by numerous nerve fibers to all parts of both cerebral hemispheres. In addition to this, it also coordinates activities like learning and reasoning. This area is responsible for functions like intersensory associations, memory, and communication.
Hence the correct answer is Associations areas - Present in the cerebellum and responsible for functions like intersensory associations, memory, and communications..

Option ‘D’ is correct

Note:
Cyton is the main part of the neuron and is also known as the cell body or soma. It is covered by a protective membrane. Dendrites are numerous highly branched cytoplasmic extensions arising from the cell body. Axon is a single, unbranched cylindrical projection that arises from the cyton.
