Question

Re-write in correct logical sequence :

Sensory nerve, dorsal root ganglion, sensory
neuron, motor neuron, receptor.

​

Answer 1

$\bold{\huge{\underline{\underline\red{ANSWER: }}}}$

RECEPTOR $\longrightarrow$DOSAL ROOT GANGALIAN $\longrightarrow$SENSORY NEURON $\longrightarrow$ MOTOR NEURON $\longrightarrow$ EFFECTOR

$\longrightarrow$ The receptors like ears , nose , skin detect the changes around us. So the signal is first detect by receptors.

$\longrightarrow$Sensory neurons carry electrical signals (impulses) from receptors or sense organs to the CNS (Central Nervous System). So it is then carried by Sensory neurons.

$\longrightarrow$ The signals then reached to Dorsal Root gangolian. It is the cluster of neurons present in spinal nerve.

$\longrightarrow$ The signals are then received by sensory neurons. They convert external stimuli to electrical impulses and activate motor neurons.

$\longrightarrow$ The signals are then received by motor neurons. It controls effector organs mainly muscles and glands.

$\longrightarrow$ The effector neuron transmits impulses from the central nervous system to an effector in order to bring about a physiological response to changes in the environment.
