Muscular System

Question 1

smooth muscle

Answer 1

muscle that lines many hollow internal organs, such as the stomach and uterus

Question 2

involuntary muscle

Answer 2

smooth muscle, which cannot
be controlled consciously

Question 3

cardiac muscle

Answer 3

involuntary muscle found only in
the heart

Question 4

skeletal/striated muscle

Answer 4

striated muscle that causes movement when contracted and is attached to bones by tendons

Question 5

voluntary muscle

Answer 5

consciously controlled skeletal muscle

Question 6

tendon

Answer 6

tough connective-tissue band that connects muscle to bone.

Question 7

myofibril

Answer 7

small muscle fiber that functions in contraction and consists of myosin and actin protein filaments

Question 8

myosin

Answer 8

protein filament in muscle cells that functions with actin in contraction

Question 9

actin

Answer 9

protein filament in muscle cells that functions with myosin in contraction

Question 10

sarcomere

Answer 10

in skeletal muscle, the functional unit that contracts and is composed of myofibrils

Question 11

what is the function of the smooth muscle

Answer 11

aid in body functions with muscle contractions

Question 12

what is the function of the cardiac muscle

Answer 12

heart beats

Question 13

what is the function of the skeletal muscle

Answer 13

mobility and stability

Question 14

skeletal muscle organization and structure

Answer 14

skeletal muscle is arranged into fibers, which are made up of myofibrils, which are arranged into sarcomeres, which have protein filaments like myosin and actin

Question 15

how do muscles contract

Answer 15

once a nerve signal reaches a muscle, the actin filaments slide toward one another, causing the
muscle to contract
