Written Exam Flashcards
What is the purpose of the collectors?
Transport lymph to lymph nodes in lymphatic trunks
Where are the superficial collectors located?
In the superficial fatty tissue, above the fascia
What is the purpose of the pre-collectors?
Connect superficial capillaries to superficial collectors
What is the purpose of the initial lymph capillary?
Lymph formation
What is the purpose of the deep lymphatic system?
Drains the muscles and tendons, joints, and inner organs
Where is the deep lymphatic system located?
Beneath the fascia
Which structures comprise the superficial lymphatic system?
Initial lymph capillaries, pre-collectors and lymph collectors
Which lymphatic structures filter, lymph fluid?
Lymph nodes
How much lymph fluid is normally returned to the venous system in 24 hours
2 to 4 L
What are the four main components of the lymphatic load?
Water, proteins, cells/cell fragments, and long chain fatty acids
What are some common conditions that can cause edema
Heart conditions, pregnancy, venous insufficiencies, renal failure, kidney disease
What is the most common cause of lymphedema in the United States?
Breast cancer surgery
What is edema?
An accumulation of water in the tissues
Where does the thoracic duct originate?
Cisterna chyli
What regional lymph nodes do the external genitalia drain into?
Inguinal lymph nodes
What group of lymph nodes do the internal reproductive organs drain into?
Pelvic lymph nodes
What percentage of lymph from the mammary gland drains into the parasternal lymph nodes? What percentage drains into the axillary lymph nodes?
25% drains into parasternal lymph nodes
75% trains into axillary lymph nodes
Where is the bottle neck of the ventromedial bundle located?
Behind the medial femoral condyle/medial aspect of the knee
Where do the three chains of the lateral circle triangle drain into?
The left or right venous angle
True or false? The clavicle forms the posterior border of the lateral cervical triangle.
False
True or false? The sternocleidomastoid muscle forms anterior border of the lateral cervical triangle.
True
What is the path of the gluteal watershed?
Starts at the sagittal watershed on posterior of the body and curves out laterally to the middle of the Glute. It’s continuation goes down to the popliteal fossa.
Where is the sagittal watershed located?
Directly in the center/midline of the body, dividing the body into left and right
Where is the location of the lower horizontal watershed? Where does it start and end?
Starts at the umbilicus and follows the caudal limitation of the rib cage to the vertebral column at the level of T 12
The horizontal watershed separates what?
Neck and shoulder territory from the arm and thorax territories
Where are most of the axillary lymph nodes located?
Between the pectoralis, major, and latissimus dorsi muscles
What is the main purpose of the lymphatic system?
To drain the substances, that cannot be drained or reabsorbed by the circulatory system, and returns them to the blood
