Hello Friend ❤️❤️
The answer of u r question is
✖️ distinguish between afferent neurons and efferent neurones.✖️
Ans:✍️✍️✍️✍️✍️✍️✍️
\huge{Afferent neurons}Afferentneurons
⭕️Neurons coming from receptors are sense organs are called afferent neurons.
⭕️These are also called sensory neurons.
⭕️ sensory neurones carry information from sensory organs like ears nose tongue and skin to brain and spinal cord.
⭕️ these are incoming neurons.
\huge{Efferent neurons}Efferentneurons
⭕️ neurones carry impulses from brain and spinal cord are called efferent neuron's.
⭕️These are also called as motor neurons.
⭕️The motor neurones carry impulses from brain and spinal cord to affected organ and are responsible for the movement of hands and legs.
⭕️These are outgoing neurons.
Hope it helps uu buddy!!❤️❤️
Thank you..☺️☺️
Answer:
option (D) represents the psychological manifestations of noise pollution.
Explanation:
(i) constriction of blood vessels does happen as a result of noise pollution, and prolonged exposure to noise pollution does induce some changes in the blood flow pattern and ultimately leads to many heart diseases or hearing losses as well.
(ii) Increase in the rate of heartbeat is the most common effect of noise pollution in the human body. If exposed to sudden high decibel sounds, the body sees it as a danger and starts to increase the blood flow which is done by fast pumping of the heart.
(iii)Digestive spasms also do occur to noise pollution, as the noises increase the anxiety in the body which gradually affects the digestive and intestinal health.
(iv)Dilation of the pupil of the eye can be seen when an individual is exposed to noise pollution due to the stress it causes.
Since all are the effects of noise pollution hence option D is the correct answer as it represents all the mentioned effects.
