What is the innervation of the bladder?

The lower urinary tract is innervated by 3 sets of peripheral nerves: pelvic parasympathetic nerves, which arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra; lumbar sympathetic nerves, which inhibit the bladder body and excite the bladder base and urethra; and pudendal nerves.

What nerve supplies the bladder?

The pudendal nerves, which originate at the S2-S4 sacral level of the spinal cord, and are the main somatic nerves, innervate the striated muscle of the pelvic floor and the external sphincter.

What is bladder with picture?

The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and controlled.

What spinal levels innervate the bladder?

The sympathetic innervation of the bladder originates in the lower thoracic and upper lumbar spinal cord segments (T10-L2), the preganglionic axons running to sympathetic neurons in the inferior mesenteric ganglion and the ganglia of the pelvic plexus.

What is the main function of the bladder?

Bladder. This triangle-shaped, hollow organ is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones. The bladder’s walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.

What side of the body is the bladder?

Bladder. This triangle-shaped, hollow organ is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones.

What nerve innervates the bladder?

Innervation of the bladder comes from the inferior hypogastric plexus. This plexus receives autonomic input from the pelvic splanchnic nerves (parasympathetic), the sympathetic trunk and sacral splanchnic nerves (sympathetic).

When does nerve damage cause bladder problems?

The underlying problem is that neuropathy (nerve damage) causes the bladder to lose the ability to sense when it is full, just as neuropathy in the feet can interfere with a person’s ability to sense pressure or pain. The result is a tendency to retain large amounts of urine in the bladder.

What causes nerve pain in the bladder?

Neurogenic bladder is the name given to a number of urinary conditions in people who lack bladder control due to a brain, spinal cord or nerve problem. This nerve damage can be the result of diseases such as multiple sclerosis (MS), Parkinson’s disease or diabetes .

Why Cant I control my pee?

Loss of urine control may develop for a number of reasons. Problems with the bladder and prostate gland are probably the most common, but in many men the cause lies outside of the urinary tract. For example, severe constipation and certain medications can reduce bladder control. In some men, more than one problem is present.
