ANATOMY

Detailed explanation-1: -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. Thus, the correct answer is option A.

Detailed explanation-2: -Neurons have specialize cell parts called dendrites and axons. Dendrites bring electrical signals to the cell body and axons take information away from the cell body.

Detailed explanation-3: -The classical view of the dendrite is that of an unmyelinated tube of cytoplasm which carries information toward the cell body. However, this distinction does not hold for ALL neurons. Some cells have a myelinated process that transmits signals toward the cell body.

Detailed explanation-4: -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.

Detailed explanation-5: -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).
