Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Dendrite has function
A
Control activities in nervous system
B
receives impulses
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Dendrites receive the data or signals from another neuron. Dendrite collects and stores all incoming information from axon terminals. Dendrites are the structures of neurons, which conduct electrical impulses toward the cell body of the nerve cell.

Detailed explanation-2: -Dendrites receive input from many other neurons and carry those signals to the cell body. If stimulated enough, a neuron fires an action potential-an electrical impulse that then stimulates other neurons. Large networks of these neurons communicate with each other to generate thoughts and behavior.

Detailed explanation-3: -Dendrite – The receiving part of the neuron. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs determining whether the neuron will fire an action potential. Spine – The small protrusions found on dendrites that are, for many synapses, the postsynaptic contact site.

Detailed explanation-4: -Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
