What else can I help you with?
Is the micturition reflex center is located in the pons?
No, the micturition reflex center is located in the sacral region of the spinal cord, specifically at the level of the S2 to S4 segments. This center regulates the process of urination, including the contraction of the bladder and relaxation of the internal urethral sphincter.
What level of the spinal cord is damaged to cause urinary incontinence?
Parasympathetic nerves from the S2, S3 and S4 levels of your spinal cord cause the upper part of your bladder to contract and your bladder neck to relax, assisting in the process of micturition (urination). If these are damaged you will have bladder control problems.
Which structure is involved in the segmental level of motor control?
Spinal cord.
What does the micturition reflex feel like?
The micturition reflex is the body's automatic response to the feeling of a full bladder and typically manifests as the urge to urinate. This sensation can vary in intensity from mild discomfort to strong urgency depending on the individual and the level of bladder fullness.
What factor decreases the excitatory level of the spinal cord?
Fatigue decreases the excitatory level of the spinal cord
Where in the body does the spinal cord end?
The spinal cord ends at the level of the first lumbar vertebra, which is just below the level of the ribs.
Car accident spinal cord was severed at the 12th level thoracic Spinal cord reflexes below this level are absent What is this called?
paraplegia
The simplest reflexes are mediated at the level of the?
spinal cord
How are the micturation reflex and conscious thought involved in urination?
The micturition reflex is an automatic process where the bladder expels urine when it reaches a certain level of fullness, controlled by the autonomic nervous system. Conscious thought can influence urination by allowing an individual to voluntarily start or stop the process, giving them some control over when and where they urinate.
What inferior boundary of the spinal cord is at the level of the vertebra?
The inferior boundary of the spinal cord typically ends at the level of the L1 or L2 vertebra in most adults.
What role does the brain play in a reflex response?
The brain initiates a reflex response by sending signals down the spinal cord to the specific muscle or organ involved. However, the actual reflex action occurs at the level of the spinal cord, without the need for input from the brain. This allows for a quicker and more automatic response to potentially harmful stimuli.
Is regulation of blood sugar level a function of the urinary system?
No
