Where is the location of the external urethral sphincter in the human male?
The external urethral sphincter in the human male is located at the base of the pelvis, surrounding the urethra as it passes through the urogenital diaphragm. It lies just below the bladder and above the perineum, playing a crucial role in controlling the release of urine from the bladder. This sphincter is composed of skeletal muscle, allowing voluntary control over urination.
Where is the external urethral sphincter located?
The external urethral sphincter is located around the urethra, which is the tube that carries urine from the bladder to outside the body. It is a voluntary muscle, meaning you have control over when you relax or contract it to release or hold urine.
What triggers the micturition response?
The micturition response is triggered by a combination of a full bladder sending sensory signals to the brain, voluntary relaxation of the external sphincter, and involuntary contraction of the bladder muscle (detrusor muscle) mediated by the parasympathetic nervous system. This process helps to empty the bladder of urine.
What happens when the external urethral sphincter is voluntarily relaxed at the same time that the pelvic splanchnic nerves are active?
When the external urethral sphincter is voluntarily relaxed while the pelvic splanchnic nerves are active, it results in the contraction of the detrusor muscle in the bladder, facilitating urination. The pelvic splanchnic nerves, which are part of the parasympathetic nervous system, stimulate bladder contraction and inhibit sphincter closure. This coordinated action allows for the expulsion of urine from the bladder through the urethra.
How many urine in the bladder when someone feels like urinating?
The average human can hold the bladder for approximately 6 hours.

What is a human bladder neck?
A human bladder neck is a constricted portion of the urinary bladder, which is formed by the meeting of its inferolateral surfaces proximal to the opening of the urethra.
Can you feel your bladder on external palpation?
Yes, in some cases, the bladder can be felt on external palpation, especially when it is distended. A full bladder may be palpable as a smooth, rounded mass in the lower abdomen, typically above the pubic symphysis. However, when the bladder is empty or not significantly distended, it is generally not palpable.

What lies between the urinary meatus and bladder?
The urethra lies between the urinary meatus (external opening) and the bladder. The urethra serves as a passage for urine to flow from the bladder to the outside of the body.

What are the different types of measurements that calipers can be used for?
