What is the difference between an orifice and sphincter?
The orifice is an opening such as the nostrils, mouth, etc. The sphincter is a muscle. These are like valves that only allow certain materials to go in and out and are often very tight, resulting in the action of peristalsis.
What is the synergist of the trapezius in scapular elevation?
The synergist of the trapezius in scapular elevation is the levator scapulae muscle. It works together with the trapezius to elevate the scapula and assist in movements like shrugging the shoulders.
Sphincter found between the esophagus and the stomach?
What is the function of the cardiac sphincter?
Sphincter controlling the movement of food from the stomach into the duodenum?
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.
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 sphincterlike action does thel levator ani provide?
The levator ani provides a sphincter-like action by supporting the pelvic floor and aiding in the maintenance of continence. It helps control the passage of urine and feces by contracting around the rectum and urethra, thus preventing involuntary leakage. Additionally, its contraction assists in stabilizing the pelvic organs during activities such as defecation and childbirth. Overall, it plays a crucial role in pelvic stability and function.
What do the levator ani and coccygeus form?
The levator ani and coccygeus muscles together form the pelvic diaphragm. This muscular layer acts as a supportive structure for the pelvic organs and helps to maintain continence by providing sphincter-like function.

The orifice is an opening such as the nostrils, mouth, etc. The sphincter is a muscle. These are like valves that only allow certain materials to go in and out and are often very tight, resulting in the action of peristalsis.
Ring like muscle that controls the flow from the stomach to the small intestine?
lower esophageal sphincter or gastroesophageal sphincter

The synergist of the trapezius in scapular elevation is the levator scapulae muscle. It works together with the trapezius to elevate the scapula and assist in movements like shrugging the shoulders.
Is the ring like muscle that controls the flow from the stomach to the small intestine?
The ring like muscle that controls the flow from the stomach to the small intestine is called the pylorus or the pyloric sphincter. It is divided into two parts: the pyloric antrum which is connected to the body of the stomach and the pyloric canal which is connected to the beginning of the small intestine (the duodenum).
Ring of muscle in the stomach?
The ring of muscle at the entrance to the stomach is the lower esophageal sphincter. This muscle is normally contracted to close the esophagus. At the lower end of the stomach food passes through the pyloric sphincter and into the duodenum of the small intestine.
What is a ring like mucle that tighly constrict the opening of a passasseway?
sphincter
What causes the cardiac sphincter to malfunction?
The cardiac sphincter, also known as the lower esophageal sphincter, may malfunction due to various reasons such as hiatal hernia, obesity, smoking, certain medications, and certain foods that can relax the sphincter muscle. This dysfunction can lead to conditions like gastroesophageal reflux disease (GERD) and heartburn.
What does a girl's anal sphincter look like?
Use a mirror. It looks a lot like yours.
What does normal sphincter tone mean in medical terms?
Normal sphincter tone refers to the appropriate level of tension and constriction in a sphincter muscle, which helps regulate the passage of substances through an opening in the body, such as the anal or esophageal sphincter. This tone is crucial for maintaining continence and ensuring proper function of the gastrointestinal tract. Abnormal sphincter tone can lead to conditions like incontinence or obstructive symptoms. Assessment often involves clinical examination or specialized tests to evaluate the function and integrity of the sphincter.
