Q

What do normal vein valves do?

A

Prevent blood backflow; any movement compresses or pulls a vein to push blood toward the heart

23
Q

What part of the lymphatic system is located in all portions of the body except CNS and cornea?

A

Lymphatics

24
Q

What are the components of the lymphatic system?

A

Lymph vessels (superficial, intermediate, deep-lymphatics), lymph fluid, and lymph tissues and organs (lymph nodes, tonsils, spleen, thymus, and thoracic duct)

25
Q

What part of the lymphatic system is absorbed at the capillary level, channeled through small vessels (precollectors) then to larger, valved vessels (collectors)?

A

Lymph fluid (Lymph)

26
Q

What part of the lymphatic system has contractile properties, smooth muscles, and valves?

A

Collectors

27
Q

What part of the lymphatic system is thinner and more likely to collapse under pressure than veins?

A

Lymphatic vessels

28
Q

How does lymph fluid move superficially?

A

Diffusion and filtration

29
Q

How does lymph fluid move below the dermis?

A

By contraction within the vessel to drive fluid deeper into the collector vessels

30
Q

What part of the lymphatic system depends on the contraction of valved lymph vessels that create a pumping force?

A

Drainage

31
Q

What type of lymphatic system is normally transported through the thoracic duct and emptied into the venous angles to the left and right jugular veins trunk?

A

Excess lymph drainage

32
Q

What part of the lymphatic system is not adversely affected by gravity?

A

Lymph flow

33
Q

What abnormal conditions cause excess lymph pooling related to gravity in LE?

A

Morbid obesity, CVI

34
Q

How does the parasympathetic, sympathetic, and sensory nerve contractions (stimulation) affect the lymphatic system?

A

Stimuli that has an impact on the lymphangion contraction

35
Q

How does the contraction of muscles adjacent to blood vessels affect the lymphatic system?

A

Stimuli that has an impact on the lymphangion contraction

36
Q

How does the pulsation of arteries adjacent to lymph vessels (even pre-capillary arterioles have pulsation) affect the lymphatic system?

A

Stimuli that has an impact on the lymphangion contraction

37
Q

How does the abdominal and thoracic cavity pressure changes during breathing affect the lymphatic system?

A

Stimuli that has an impact on the lymphangion contraction

38
Q

How does volume changes within each lymphanion (internal receptors respond to tension and trigger a contraction) affect the lymphatic system?

A

Stimuli that has an impact on the lymphangion contraction

39
Q

How does mild mechanical stimulation of dermal tissues (manual lymphatic drainage (MLD) techniques will increase frequency of lymphangion contractions?)

A

Stimuli that has an impact on the lymphangion contraction

40
Q

What system is also referred to as an organ?

A

Integumentary

41
Q

What system is most often seen/touched and examined by a physical therapist?

A

Integumentary

42
Q

What system has a functional relation with many other body systems?

A

Integumentary

43
Q

A

Integumentary

44
Q

What is the outermost layer of skin, avascular, and water resistant?

A

Epidermis

45
Q

What layer of skin provides protection from infection, abrasions, and chemicals and assists with heat regulation, retention, and dissipation?

A

Epidermis

46
Q

What is present in the epidermis, determines skin color, and provides protection from ultraviolet radiation?

A

Melanocytes

47
Q

What layer of skin regenerates rapidly, allowing individuals to heal quickly when conditions are normal?

A

Epidermis

48
Q

What layer of skin is 20-30 times thicker than the epidermis?

A

Dermis

49
Q

What layer of skin contains blood vessels and lymphatics, nerve and nerve endings, and sensory neurons that all supply the epidermis?

A

Dermis

50
Q

What layer of skin contains hair follicles, sweat glands, sebaceous glands, and nails?

A

Dermis

51
Q

What skin layer has contents that are surrounded and supported by collagen, elastin, and ground substance that provides structure, strength, flexibility, and elasticity?

A

Dermis

52
Q

What layer of skin is also known as the subcutaneous layer?

A

Hypodermis

53
Q

What layer of skin is not part of the integument but important in stabilizing skin over skeletal muscles and organs?

A

Hypodermis

54
Q

What layer of skin consists of loose connective tissue and fat cells, and provides insulation and protection to underlying structures?

A

Hypodermis

55
Q

What layer of skin plays an important role in the prevention of pressure injuries, especially over ischial tuberosities and greater trochanter?

A

Hypodermis

56
Q

What is the sequelae of impaired components of the integument after injury?

A

Decreased lubrication, loss of elasticity, increased scar formation, loss of tensile strength, decreased ability to resist infection, and increase or decrease in sensitivity.
