65
Q

Lymphatic System

A

Composed of an extensive network of capillaries, collecting vessels. lymph nodes, and lymphoid organs, and serves to return excess fluid from between the cells (interstitial fluid) back to the bloodstream, thereby preventing swelling of the intercellular spaces (edema).
Lymph fluid is very similar to blood, except that it contains no red blood cells or platelets, as these components cannot escape through the blood-vessel walls. Once lymph enters the blood through specialized vessels called lymphatic capillaries, it circulates though the arteries, blood capillaries, and veins.
Four important functions:
1. Destruction of bacteria and other foreign substances that are present in lymph nodes
2. Specific immune responses that aid in manufacturing antibodies to destroy bacteria and foreign substances
3. The return of interstitial fluid to the bloodstream
4. Prevention of excessive accumulation of tissue fluid and filtered proteins by drainage into highly permeable lymphatic capillaries in the connective tissues

Three Main Types of Joints

A
  1. Fibrous
  2. Cartilaginous
  3. Synovial
79
Q

Fibrous Joints

A

Held tightly together by a fibrous connective tissue and allow little or no movement. Classified as synarthroidal (syn = together. arthro = joint) considered immovable joints (include sutures of the skull and the joint between the distal ends of the tibia and fibula).

80
Q

Cartilaginous Joints

A

Bones are connected by cartilage and little or no movement is allowed.

81
Q

Synovial Joints

A

Most common. Freely moveable. (Diathroses “through joint”)

82
Q

Aorta

A

Major artery delivery blood from the heart to the body

83
Q

Superior/Inferior Vena Cava

A

Major veins returning blood to the heart from the body

84
Q

Pulmonary Circuit

A

Carbon dioxide is exchanged for oxygen in the lungs

85
Q

Systemic Circuit

A

Heart pumps oxygenated blood to tissues throughout the body

86
Q

Synovial Fluid

A

Fluid created in the synovial membrane by capillaries to nourish the articular cartilages and lubricate the joint surfaces.

87
Q

Articular Disks

A

Fibrocartilage (menisci in the knee)

88
Q

Medial and Lateral Meniscis

A

Help absorb shock in the knee, increase joint stability, direct synovial fluid to aid in nourishment of the knee, and increase joint contact surface area, thereby decreasing overall pressure on the joint.

89
Q

Axis of Rotation

A

An imaginary line that forms a right angle to the plane of movement about which a joint rotates.

90
Q

Uniplanar or Uniaxial Joints

A

(Hinge Joints) Joints that move in one plane only and have one axis of rotation. (Ankles, elbow)

91
Q

Biplanar or Biaxial Joints

A

Joints that allow movement in two planes that are perpendicular to each other. (Foot, knee, hand, wrist).

92
Q

Multiplanar or Triaxial Joints

A

Joints that allow movement in three axes of rotation. (Hip, thumb, shoulder).

93
Q

Four General Groups of Movement

A
  1. Gliding
  2. Angular
  3. Circumduction
  4. Rotation
94
Q

Gliding

A

The surfaces of two adjoining bones move back and forth upon each other.

95
Q

Four General Groups of Movement

A
  1. Gliding
  2. Angular
  3. Circumduction
  4. Rotation
96
Q

Angular

A

An increase or decrease in the angle between two adjoining bones.
There are four angular movements defined for synovial joints:
1. Flexion
2. Extension
3. Abduction
4. Adduction

97
Q

Flexion

A

Bones comprising a joint move toward each other in the sagittal plans, decreasing the joint angle between them.

98
Q

Extension

A

The opposite of flexion. Causes the angle between two adjoining bones to increase in the sagittal plane.

99
Q

Abduction

A

When part of the body is moved away from the midline of the body, such as lifting an arm or leg away from the side of the body.

100
Q

Adduction

A

The opposite of abduction. Refers to movement of a body part toward the midline of the body.

101
Q

Circumduction

A

The incorporation of all four angular movements to create one motion (flexion, extension, abduction, adduction).

102
Q

Rotation

A

Motion of a bone around a central (longitudinal) axis.

103
Q

Pronation or Supination

A

Occurs at the radioulnar joint.
Supination (rotation so palm faces anteriorly).
Pronation (rotation so palm faces posteriorly).
