What else can I help you with?
What closes like a rubber band around the opening of the bladder?
The sphincter muscle closes like a rubber band around the opening of the bladder to prevent urine from leaking out. This muscle is controlled by nerves and can be consciously relaxed or contracted to release or hold urine in the bladder.
What are the Sensory and motor innervations of the skin of the sides and front of the body are provided by?
The sensory innervation of the skin of the sides and front of the body is primarily provided by the intercostal nerves. These nerves also contribute to motor innervation of the muscles between the ribs. Additionally, the skin of the front of the body receives sensory innervation from the anterior cutaneous branches of the thoracoabdominal nerves.
Which upper limb muscles has double innervation?
The flexor carpi ulnaris muscle is an upper limb muscle that has double innervation from both the ulnar and medial nerves.
Spinal nerves exiting the cord from the level of L4 to S4?
Spinal nerves exiting the cord from the level of L4 to S4 supply motor and sensory innervation to the lower extremities, including the buttocks, thighs, legs, and feet. They contribute to functions such as walking, standing, and bladder control. Damage to these nerves can lead to symptoms such as weakness, numbness, and pain in the lower body.
Where are ther nerves to the colon located in the spine?
The nerves that innervate the colon originate from the spinal levels T10-L2. These nerves form the superior mesenteric plexus, which supplies the colon with autonomic innervation.
What is the opening of the bladder is regulated by?
The opening of the bladder, known as the internal urethral sphincter, is regulated by the autonomic nervous system. Specifically, sympathetic nerves control its contraction, preventing urine from leaking, while parasympathetic nerves facilitate its relaxation during urination. Additionally, the external urethral sphincter, which is under voluntary control, allows for conscious regulation of urine flow.
Nerve supply of the urinary bladder?
The bladder receives motor innervation from both sympathetic fibers, most of which arise from the hypogastric plexuses and nerves, and parasympathetic fibers, which come from the pelvic splanchnic nerves and the inferior hypogastric plexus. Ahmed Urbizo

What is a muscle that controls the release of urine?
The smooth muscle (caled the Detrousar muscle) that is part of the bladder contractsto help push urine out. The bladder also has two sphincters the internal, or involuntary and the external, or voluntary sphincters are also muscle.
Nervous control of urination involves what mechanism?
Nervous control of urination involves the bladder mechanism. The bladder mechanism involves filling and releasing of the bladder. The mechanism is controlled by various muscles such as the pelvic floor muscle and sphincter muscles.
Which upper limb muscles has double innervation?
The flexor carpi ulnaris muscle is an upper limb muscle that has double innervation from both the ulnar and medial nerves.
What is the spinal nerves related to the sacral plexus?
It provides innervation to the pelvis, its organs and the lower limb

Interval between arrival of water at the sphincter and the opening of the sphincter?
The interval between the arrival of water at the sphincter and the opening of the sphincter is controlled by the nervous system. This process involves sensory nerves detecting the presence of water in the rectum, which then signals motor nerves to relax the sphincter muscles, allowing for the passage of the water. The time it takes for this reflex to occur can vary among individuals based on factors like hydration levels and the sensitivity of their nervous system.
What is emptying the bladder controlled by?
The micturition reflex tells you when you need to empty your bladder. This happens on average four to eight times a day. The reflex is controlled by your central nervous system. When your bladder is about half full, the stretch receptors in the walls of your bladder become active and send signals along your pelvic nerves to your spinal cord. A reflex signal is sent back to your bladder, which makes the detrusor muscle in the bladder wall contract. The contraction increases the pressure in your bladder, and this is what makes you want to pass urine. Because the external sphincter is under voluntary control, you don't urinate until you decide to relax this muscle. simple answer would be this; Sphincter muscle that surrounds the urethra.
