What specific structural characteristic makes voluntary control of urination and defecation possible?
The specific structural characteristic that enables voluntary control of urination and defecation is the presence of external sphincters, such as the external urethral sphincter and the external anal sphincter. These are skeletal muscles that can be consciously contracted or relaxed, allowing individuals to control the release of urine and feces. Additionally, the neural pathways, including the somatic nervous system, play a crucial role in facilitating this voluntary control.

What is the urination results from an involuntary and voluntary process called?
The urination results from both involuntary and voluntary processes are collectively referred to as micturition. Involuntarily, the bladder fills and stretches, triggering signals to the brain that create the urge to urinate. Voluntarily, an individual can choose to initiate urination by relaxing the external urethral sphincter. This coordinated effort between the nervous system and muscle control allows for the regulation of urine flow.
The internal and external sphincters are associated with?
The internal and external sphincters are primarily associated with the regulation of urine flow from the bladder and the control of bowel movements. The internal sphincter is an involuntary muscle that helps maintain continence by keeping the urethra closed, while the external sphincter is a voluntary muscle that allows for conscious control over urination and defecation. Together, they play crucial roles in the functioning of the urinary and digestive systems.
What is urination known as?
Urination is scientifically known as micturition. It refers to the process of expelling urine from the urinary bladder through the urethra to the outside of the body. This process is regulated by the nervous system and involves both involuntary and voluntary muscle contractions. Urination is a vital bodily function for maintaining fluid and electrolyte balance.
When you can wee what is it called?
The ability to control when you urinate is known as voluntary urination, while the inability to control it is referred to as urinary incontinence.
Which sphincter allows for defecation and is under voluntary control?
The external anal sphincter is under voluntary control. You have the urge to defecate because your internal anal sphincter involuntarily opens, but you can keep yourself from going to the bathroom because your external anal sphincter is voluntarily closed. Hope that helps!
The characteristic of capitalism that buyers and sellers will freely and willing exchange in market transaction is called?
