Micturition is carried out by a reflex. ...
Introduction:
Micturition is the process of urination, which is carried out by a reflex. It is an important physiological process, which is controlled by the nervous system.
Explanation:
The process of micturition involves the contraction and relaxation of the muscles in the bladder and urethra. The bladder is a hollow muscular organ that stores urine until it is ready to be eliminated from the body. The urethra is the tube that carries urine from the bladder to the outside of the body.
When the bladder is full, it sends signals to the spinal cord, which then sends signals to the brain. The brain, in turn, sends signals back to the bladder and urethra to initiate the process of urination. This process is carried out by a reflex.
The micturition reflex involves two phases:
1. Storage phase: During this phase, the bladder is relaxed, and the urethral sphincter is contracted, which prevents urine from leaving the bladder.
2. Voiding phase: During this phase, the bladder contracts, and the urethral sphincter relaxes, which allows urine to leave the bladder and flow out of the body.
The micturition reflex is controlled by both the autonomic and somatic nervous systems. The autonomic nervous system controls the involuntary contractions of the bladder, while the somatic nervous system controls the voluntary relaxation of the external urethral sphincter.
Conclusion:
In conclusion, micturition is carried out by a reflex, which involves the contraction and relaxation of the muscles in the bladder and urethra. This process is controlled by the nervous system and is essential for the elimination of waste from the body.
Micturition is carried out by a reflex. ...
Micturition is carried out by a reflex is True. The process of emptying urine from the storage organ, called the urinary bladder is called as Micturition. ... The centre of the micturition is present in the spinal cord. It follows a period of inhibition by the brain, by relaxing the external sphincter.
