Flashcards in 5.1 types of muscle Deck (29):
what percentage of body mass does muscle tissue make up?
what is muscle tissue made up of?
muscle fibres held together by connective tissue that can contract or relax to shorten and lengthen the muscle
what are the three types of muscle?
where is cardiac muscle found?
give some properties of cardiac muscle:
where is smooth muscle found?
lining many internal organs
is smooth muscle voluntary or involuntary?
involuntary - controlled by autonomic nervous system
how do smooth muscle fibres contract?
are slow muscle fibres slow or quick to fatigue?
what is skeletal muscle essential for?
voluntary movement and maintaining posture
how is skeletal muscle attached to bones?
is skeletal muscle voluntary or involuntary?
how do skeletal muscle fibres appear?
how do cardiac muscle fibres appear?
how do smooth muscle fibres appear?
how is skeletal muscle arranged and why?
so muscle contracts in one direction
how is cardiac muscle arranged and why?
branched cells that interconnect resulting in simultaneous contraction
how is smooth muscle arranged and why?
non regular arrangement
different cells can contract in different directions
what is the contraction speed of skeletal muscle?
what is the contraction speed of cardiac muscle?
what is the contraction speed of smooth muscle?
what is the length of contraction time for skeletal muscle?
what is the length of contraction time for cardiac muscle?
what is the length of contraction time for smooth muscle?
long - remains contracted for a relatively long time
which type of muscle is multinucleated?
which types of muscle are uninucleated?
what is the function of skeletal muscle?
help you to move your bones
what is the function of smooth muscle?
e.g. smooth muscle contracts in the oesophagus to move food to the stomach by peristalsis
