Functions Of The Muscular System Flashcards
7 major functions of the muscular system
Movement of the body Maintenance of posture Respiration Production of body heat Communication Constriction of organs and vessels Constraction of the heart
What function is when the contraction of skeletal muscles is responsible for the movements of the body such as walking, running etc ?
Movement of the body
What function is when the skeletal muscles maintains tone, which keeps us sitting or standing erect ?
Maintenance of posture
What function is when the muscles of the thorax carry out breathing movements ?
Respiration
What function is when the skeletal muscles contract, heat is given off as a by product ?
Production of body heat
What function is when the skeletal muscles are involved in all aspects of communication such as speaking, writing, etc ?
Communication
What function is when the contraction of smooth muscle within the walls of internal organs and vessels causes structures to constrict ?
Constriction of organs and vessels
What function is when the contraction of cardiac muscle causes the heart to beat, propelling blood to all parts of the body
Contraction of the heart
What are the four characteristics of muscle tissue ?
Contractility
Excitability
Extensibility
Elasticity
Is the ability of muscle to shorten forcefully, or contract
Contractility
Is the capacity of muscle to respond to a stimulus
Excitability
Muscle can be stretched beyond its normal resting length
Extensibility
Ability of muscle to recoil to its original resting length after it has been stretched
Elasticity
System of naming skeletal muscle organs
Nomenclature
Outer membrane of the long, cylindrical muscle fiber
Sarcolemma
