Nervous Control and Coordination

In a neuron, conversion of electrical signal to chemical signal occurs at

• Axonal end

• Dendritic end

• Cell body

• Axon

Correct sequence of electrical impulse transmission in a neuron is from

• dendrite, axon, axonal end,cell body

• cell body, dendrite, axon,axonal end

• dendrite, cell body, axon, axonal end

• axonal end, axon, cell body, dendrite

Which is the correct sequence of the components of a reflex arc

• Receptors, spinal cord,sensory neuron, motor neuron, muscle

• Receptors, muscle, sensory neuron, motor neuron, spinal cord

• Receptors, sensory neuron, spinal cord, motor neuron, muscle

• Receptors, motor neuron, spinal cord, sensory neuron, muscle

Posture and balance of the body is controlled by

• Cerebrum

• Cerebellum
