A man afraid when he walked bare feet at dark over a soft and cool object and jumped. What roles his parts of the body in this event played and what is this event called?
Answers
Answer:
legs and jumping
Explanation:
Answer:
This event is called reflex action.
Explanation:
At first the stimulus is got while touching the soft and cool object. Then the stimulus activates the nerve cells. After this the sensory nerve fibre conducts impulses from receptor to the spinal chord. Then the intermediate nerve fibre present in spinal chord changes sensory impulses to motor impulses. Now the motor nerve transmit and conducts the motor impulses from spinal chord to the effector (i.e. legs). When the effector (i.e. legs) receives the impulse then the action of jumping is performed by the leg.
Before jumping when man got stimulus he was afraid due to blood circulation in such a way. The sympathetic nervous system then stimulated the involuntary activities of afraidation in body occured. After completetion of reflex action the man jumped.
Hence likethis his body parts played a significant role in jumping.
