Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A Dendrite ____
A
carries information towards the body of the neuron
B
carries information away from the body of the neuron
C
sends impulses to other neurons
D
acts as the cell’s nucleus
Explanation: 

Detailed explanation-1: -Dendrites are the branched thread-like extensions of a neuron that carry impulses from nearby neurons to the cell body (cyton). Axons carry impulses away from the cyton.

Detailed explanation-2: -Dendrites are the extensions of a cell body of a neuron. They receive signals from sensory receptors or other neurons and bring them towards the cell body.

Detailed explanation-3: -Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons. The number of dendrites on a neuron varies. They are called afferent processes because they transmit impulses to the neuron cell body.

Detailed explanation-4: -Synapses. Neuron-to-neuron connections are made onto the dendrites and cell bodies of other neurons. These connections, known as synapses, are the sites at which information is carried from the first neuron, the presynaptic neuron, to the target neuron (the postsynaptic neuron).
