Chapter 30 - Musculoskeletal Trauma and Nontraumatic Frectures Flashcards
the functions of the muscularskeletal system are: 1 2 3 4 5
give the body shape protect internal organs provide for movement store salts and other materials for metabolism produce red blood cells
three kinds of muscle:
cardiac
voluntary (skeletal)
involuntary (smooth)
connect the muscle to the bone
tendons
connect bone to bone
ligaments
a strong, smooth, flexible, compressible, and slippery substance found at the point of articulation of two bones. allows the bones to ride over each other during movement with relatively little friction.
cartilage
bending motion that moves the extremity toward the body
flexion
bending motion that moves the extremity away from the body
extension
movement of a body part toward the midline of the body
adduction
movement of a body part away from the midline of the body
abduction
turning along the axis of the bone or joint
rotation
movement through an arc of a circle or in a circular motion from a central point
circumduction
skeletal systems 6 basic components
skull thorax pelvis upper extremities lower extremities spine
the axial skeletal system is composed of:
head
thorax
spine
the appendicular skeletal system is made up of:
bones in extremities
including:
shoulder girdle and pelvis
bones of upper extremity: which consists of: shoulder girdle arm forearm hand
clavicle scapula humerus radius ulna carpal metacarpals phalanges
