Lesson 2 (Part 1) Flashcards
Windows/approaches
Refers to where we are best able to view the organ
- trying to get the best view of the structure/organ
- can use different windows to look at the same organ
What are techniques to get good windows? (2)
- Move the transducer
2. Angle to probe
Maneuvers
Ways to create better windows
What are 3 example of maneuvers?
- Ask them to take a deep breath in
- Drink water in order to see the pancreas better
- Pushing the abdomen out
Where is the near field?
Is the interior portion which is nearest to the transducer
- the top
Where is the far field?
Is the outer portion which is farthest from the transducer
- the bottom
What are the 4 borders of the abdominal pelvic cavity?
- Superior = diaphragm
- Inferior = pelvic floor
- Posterior = spine and muscles
- Anterior = abdominal wall
What is another term of the abdominopelvic cavity?
Peritoneal cavity
What is the largest body cavity?
Abdominopelvic cavity
What is included in the abdominopelvic cavity? (2)
- Abdomen cavity
2. Pelvic cavity
Peritoneum
As serous membrane that lines the abdominal cavity
What does the serous membrane secrete?
Serous fluid
- reduces friction
What are 2 layers in cavities?
- Parietal
2. Visceral
What does the parietal layer line?
Abdominal walls
What does the visceral layer line?
Organs
Parietal peritoneum
The portion of the peritoneum that forms a closed sac
What is the difference in parietal peritoneum for females and males? (2)
- Females = The section is open to the fallopian tubes
2. Males = It is a closed cavity
What does the parietal peritoneum divide?
The organs/structures into intraperitoneal and retroperitoneal
Intraperitoneum
Organs within the peritoneum, between the visceral and parietal layers
What are the intraperitoneal organs? (6)
- Liver (except the bare area)
- Gallbladder
- Spleen
- Stomach
- Overies
- Majority of the intestines
How does the intraperitoneal organs in females communicate to the exterior? (3)
Through the…
- Uterine tubes
- Uterus
- Vagina
How does the intraperitoneal organs in males communicate to the exterior?
It doesnt because it is a closed cavity
Retroperitoneum
Organs that lie outside of the peritoneal cavity
- posterior
What are examples of retroperitoneum organs? (7)
- Aorta
- IVC
- Pancreas
- Kidneys
- Urinary bladder
- Rectum
- Majority of the duodenum
What are 2 female retroperitoneum organs?
- Uterus
2. Vagina
What is the retroperitoneum organ in males?
The prostate
How are our organs held in place? (2)
- Ligaments
2. Mesentry
Ligaments
A short band of tough, flexible fibrous connective tissue which connects two bones or cartilages or holds together a joint
Mesentry
A double fold of periteneum which holds things that are used to attach to abdominal walls or different organs
What structures should you think of when you talk about ligaments?
Organs
What structures should you think of when you talk about mesentery?
Bowel
