Flashcards in Chapter 30 - Musculoskeletal Trauma and Nontraumatic Frectures Deck (27):
the functions of the muscularskeletal system are:
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:
connect the muscle to the bone
connect bone to bone
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.
bending motion that moves the extremity toward the body
bending motion that moves the extremity away from the body
movement of a body part toward the midline of the body
movement of a body part away from the midline of the body
turning along the axis of the bone or joint
movement through an arc of a circle or in a circular motion from a central point
skeletal systems 6 basic components
the axial skeletal system is composed of:
the appendicular skeletal system is made up of:
bones in extremities
shoulder girdle and pelvis
bones of upper extremity:
which consists of:
bones of the lower extremity:
which consists of:
pelvis (including ilium, ischium, and pubis)
a break in the continuity of a bone
tingling or abnormal sensation; may be nerve injury
loss of feeling; may be nereve injury
weakness; may be nereve injury
loss of muscle control; may be nereve injury
inability to move the extremity
decreased pulse amplitude, increased cap refill
degenerative bone disorder associated with an accelerated loss of minerals, primarily calcium, from the bone.
an injury to a muscle or a muscle and tendon, possibly caused by overextension, or overstretching.
an injury to a joint capsule, with damage to or tearing of the connective tissue, and usually involves ligaments.
the displacement of a bone from its normal position in a joint.
a force that causes injury some distance away from the point of impact
a force that twists a bone while one end is held stationary
when assessing an extremity for the possibility of a fracture or dislocation, remember to evaluate the six P's:
