Urogenital diaphragm
Older texts have asserted the existence of a urogenital diaphragm, also called the triangular ligament, which was described as a layer of the pelvis that separates the deep perineal sac from the upper pelvis, lying between the inferior fascia of the urogenital diaphragm and superior fascia of the urogenital diaphragm.
What does the diaphragm do in a microscope?
A diaphragm on a microscope is the piece that enables the user to adjust the amount of light that is focused under the specimen being observed. A diaphragm is typically found on higher-power microscopes versus less expensive or toy models. The diaphragm is located directly under the stage or platform where user places the specimen or slide.

The word urogenital is used because the urinary and reproductive systems in males merge. The male urogenital system consists of several parts, including the testes, epididymis, vas deferens, ejaculatory ducts, urethra, penis, prostate and accessory glands.
What is the diaphragm in respiratory system?
The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.
What is the anatomy of diaphragm?
The diaphragm is an upward curved, c-shaped structure of muscle and fibrous tissue that separates the thoracic cavity from the abdomen. The superior surface of the dome forms the floor of the thoracic cavity, and the inferior surface the roof of the abdominal cavity.
What passes through the urogenital diaphragm?
The urethra and the vagina, though part of the pouch, are usually said to be passing through the urogenital diaphragm, rather than part of the diaphragm itself. Some researchers still assert that such a diaphragm exists, and the term is still used in the literature.

The urogenital diaphragm is external and inferior to the pelvic diaphragm. The pelvic diaphragm is a wide but thin muscular layer of tissue that forms the inferior border of the abdominopelvic cavity.
Which part of the urethra is within the urogenital diaphragm?
The membranous urethra lies within the urogenital diaphragm surrounded by the sphincter urethrae muscle and is the least dilatable portion of the urethra. The prostatic and membranous urethra are lined with transitional epithelium. The spongy (cavernous) urethra is enclosed in the corpus spongiosum.
Which muscle is part of the urogenital diaphragm and constricts the urethra?
The urogenital diaphragm is composed of two muscles: the deep transverse perineal muscle and the urethral sphincter.
What are some differences between the diaphragm and the pelvic diaphragm?
The difference is as follows: The pelvic diaphragm forms the pelvic floor with two muscle pairs coccygeus and levator ani as its components. It is present at the inferior end of the trunk. The diaphragm separates the abdominal and thoracic cavities and is actively involved in breathing movement.
Is urogenital diaphragm and perineal membrane same?
The perineal membrane is an anatomical term for a fibrous membrane in the perineum. The term "inferior fascia of urogenital diaphragm", used in older texts, is considered equivalent to the perineal membrane....Perineal membraneTA22444FMA30514Anatomical terminology7 more rows
Is pelvic floor and pelvic diaphragm the same?
The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus muscle, and associated connective tissue which span the area underneath the pelvis.
What are the 3 pelvic floor muscles?
The levator ani composes the bulk of your pelvic floor muscles and consists of three separate muscle components: pubococcygeus, puborectalis and iliococcygeus. The levator ani wraps around the entirety of your pelvis. Coccygeus. The coccygeus is the smaller muscle component in your pelvic floor muscles.

What is the diaphragm of the pelvic floor?
The term "urogenital diaphragm" is often confused with the pelvic diaphragm ( pelvic floor ), which is a true diaphragm supporting many of the pelvic organs.
What is the vertical section of the bladder?
Vertical section of bladder, penis, and urethra. Older texts have asserted the existence of a urogenital diaphragm, also called the triangular ligament, which was described as a layer of the pelvis that separates the deep perineal sac from the upper pelvis, lying between the inferior fascia of the urogenital diaphragm (perineal membrane) ...
Is the urethra part of the pouch?
The urethra and the vagina, though part of the pouch, are usually said to be passing through the urogenital diaphragm, rather than part of the diaphragm itself. Some researchers still assert that such a diaphragm exists, and the term is still used in the literature. The urethral diaphragm is an anatomic landmark used in radiologic ...
What is the inferior layer of the urogenital diaphragm called?
The inferior layer of fascia is often called as the perineal membrane.
What is the confined space between the superficial and deep layers of fascia called?
The confined space which is enclosed among the superficial and deep layer of fascia is called the deep perineal pouch. On the deeper part it is wrapped by a thin layer of endopelvic fascia referred to as superior fascia of the urogenital diaphragm, and on the superficial part it is enveloped by the perineal membrane named inferior fascia ...
What is the function of the diaphragm?
If you’re wondering as to what is the main function of the diaphragm, then it is to help in breathing. When a person inhales, the diaphragm contracts and thus, enlarges the space available in the thoracic cavity. The external intercostal muscles also help bring about this enlargement of the thoracic cavity.
What is the diaphragm?
Anatomy of Diaphragm. The diaphragm is a dome-shaped musculo-fibrous septum that separates the thoracic cavity from the rest of the abdominal cavity. Hence, its convex upper surface forms the floor of the thoracic cavity and the concave lower surface forms the roof of the abdominal cavity. The peripheral part of the diaphragm consists ...
Why does the diaphragm relax after inhalation?
After inhalation, when the diaphragm relaxes, air is exhaled due to the elastic recoil of the lungs and the tissues lining the thoracic cavity. The abdominal muscles also help in this, by acting as antagonists to the effects of diaphragm.
What are the pathological conditions that affect the diaphragm?
There are quite a few pathological conditions that can lead to disruption of normal diaphragm functioning. Hiatal hernia is condition wherein the abdominal esophagus or fundus of the stomach rise up through the esophageal hiatus into the thoracic cavity.
What muscles help with diaphragm?
The abdominal muscles also help in this, by acting as antagonists to the effects of diaphragm. There is a specific type of breathing which is known as diaphragmatic breathing or abdominal breathing. This is the act of breathing deep into the lungs by flexing the diaphragm.
What is the role of the diaphragm in breathing?
Diaphragm plays a very important role in the process of breathing. Contraction and expansion of the dia phragm, helps in inhaling and exhaling air. Let’s understand the function of diaphragm with the help of a diagram. The diaphragm is a sheet of internal muscle which extends across the bottom of the rib cage.
What is the peripheral part of the diaphragm?
The peripheral part of the diaphragm consists of muscular fibers that take origin from the circumference of the inferior thoracic aperture and converge to insert into a central tendon. The diaphragm is innervated by the phrenic nerve which ensures that it functions properly. The diaphragm is pierced by various apertures to permit of the passage ...
What is the function of the diaphragm?
The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs.
Why is the diaphragm important?
The diaphragm is one of the body’s most important muscles because of its crucial role in breathing.
What is an acquired diaphragmatic hernia?
In this case, it’s called an acquired diaphragmatic hernia (ADH). Symptoms can vary depending on the size of the hernia, the cause, and the organs involved. They may include: Both an ADH and CDH require immediate surgery to remove the abdominal organs from the chest cavity and repair the diaphragm.
How to strengthen the diaphragm?
exercising within your limits. Like any muscle, you can also strengthen your diaphragm with special exercises. Diaphragmatic breathing or abdominal breathing is the best way to do this. It involves inhaling deeply and slowly through the nose so that your lungs fill with air as your belly expands.
Why does my diaphragm feel tight?
During a spasm, the diaphragm doesn’t rise back up after exhalation. This inflates the lungs, causing the diaphragm to tighten. This can also cause a cramping sensation in the chest. Vigorous exercise can cause the diaphragm to spasm, which often results in what people call a side stitch.
How long does it take for a diaphragm spasm to go away?
Diaphragm spasms usually go away on their own within a few hours or days.
How do you know if you have a diaphragm problem?
