Moscow Skeletal Flashcards
Is the network of muscles bones cartilage tendons ligaments and other connective tissues that support and move the body
Muscoskeletal system
Musculoskeletal system provides three functions
Structure, stability and enables a movement
The body consists of three types of muscles
Skeletal smooth and cardiac
The musculoskeletal system is made up of how many skeletal muscles
650
Four functions of muscular skeletal system
Movement
posture
stabilize joints
generate heat
What are the examples of involuntary muscles
Muscles of the heart
the intestine
the kidneys and
lungs
What are the voluntary muscles
Pectorals deltoid biceps quadriceps
Hamstrings gluteals triceps
Gives six skeletal muscle movements
Abduction adduction circumduction inversion eversion extension
What are the functions of the bones
Provide structure give protection and serve as levers store calcium and produce blood cells
How many bones make up the axial skeleton and the appendicular skeleton
206
What are The axial skeleton
Head and trunk
What are the appendicular skeleton
Extremities shoulder and hips
Bony structure and connective tissues accounts for approximately what percent of the body weight
25%
It is the framework of bones and cartilage that supports and protects the soft tissues and internal organs of the body
Skeleton
What are the four types of bones
Long bone
short bones
flat bones
irregular bones
Give examples of a long bone
Femur humerus and ulna
It is the cushioning tissue within a joint so that the bone ends do not rub together
Cartilage
Is a small band of dense white fibrous elastic tissue connect bones to each other to joint level to limit this location and provides stability while permitting controlled movement at the joint
Ligament
It connects muscles to bones when muscles contract tendons at each end of the muscle cause the bone to move
Tendon
It is where two bones meet they make the skeleton flexible and without them movement would be impossible
Joints
What are the three classification of joints
Synathroses or fibrous
Amphiarthroses or cartilaginous
Diarthroses or synovial
Occurs when the middle joint of a finger bends in word while the joint at the ends points outward it can affect any finger or the thumb
Boutonniere deformity
It is a condition that affects the joints in the fingers It can lead serious physical impairment
Swan neck deformity
Describes an injury to the tip of a finger or thumb that stops it from being able to straighten properly
Mallet finger
