Mobility Requires __,___,___ to function in unison Muscle
skeleton
Nerves
Mobility Nursing Goals: Assist in preserving, maintaining, and restoring as much mobility and function as
possible
What is ambulation? Independent walking
Musculoskeletal refers to: muscles and the skeleton
Muscles provide the: Motor movement or force of movement
How many muscles are there in the body? Over 600
How much of your body weight is accounted for with Half a persons weight
muscle?
A contracted joint creates: A force to pull against the skeleton
The muscular system has high demand for: Oxygen and glucose
Oxygen and glucose in the muscular system Make it difficult to build and maintain muscles
Four properties of a muscle CEEE
, CEEE stands for: Contractibility
Excitability
Extensibility
Elasticity
Contractibility the ability to shorten and then relax the muscle
Excitability Muscle fibers can receive and respond to nerve or hormonal stimulation
A resting muscle is Negatively charged
A stimulated muscle is positively charged and active
Extensibility The ability to stretch which occurs as other muscles contract
Elasticity The ability to bounce back or recoil to its original state after being contracted or
extended
Three main types of muscles Cardiac
Smooth
Skeletal
Cardiac muscle Located only in the heart
functions involuntarily
Smooth muscle Located in the blood vessels and the visceral organs
functions involuntarily
Skeletal muscle Attached to the skeleton by tendons
Functions voluntarily
MCPGM Muscles contract and pull to generate movement.
Skeletal System is made up of 206 bones
Bones are made up of Hard connective tissue and provide structure
Bones are the weight-bearing organ of the body
Bones function Mechanically protect and support internal organs and muscles and store
important minerals
Long bone Characteristics: *Weight bearing
*Larger in length than width
Short Bone Characteristics: *Small, Cube shaped
*Found in wrists and ankles
