Skeletal, cardiac, smooth
What are the five functions of muscle?
skeletal movement, maintain posture, support soft tissue, guard entries/exits, and maintain body temperature
Name the smallest contractile unit of a muscle
Provide another term for muscle cell
What are the connections for connecting muscle to bone?
bundle of muscle fibers
Define motor unit
neuron and muscle fibers it stimulates
What protein makes up thick filaments
myosin (thing: actin)
What is the area of the sarcomere where there are no thick filaments?
What are the three connective tissues in skeletal muscle and what do they cover?
epimysium: entire muscle, perimysium: covers fascicles, endomysium: surrounds individual muscle fibers
What is the neurotransmitter for skeletal muscle tissue?
Starting with sacromere, build the layers of the skeletal muscle.
sarcomeres, myofibril, muscle fiber, fascicle, whole muscle
What are the two types of muscle contractions?
Isometric: builds up tension in muscles but no movement, isotonic: movement occurs
