Muscle tissue Flashcards
Name and describe the 3 types of muscles
Cardiac (striated and involuntary)
Smooth (involuntary)
Skeletal (voluntary and striated)
name the three layers of muscle connective tissues
Endomysium, perimysium, epimysium
Name the three types of myofilaments
Actin, myosin, titin
What does titin do
limits length of sarcomere
Name the steps for contraction
innervation of muscle –> fiber
neuromuscular junction (synaptic terminal and motor end plate)
signal transmission ( sarcolemma –> t-tubule –> sarcoplasmic reticulum (at triad)
contraction ( calcium release –> active-site exposure –> sliding)
Name three factors that go into the naming of muscls
shape of muscle
number of muscle cells
size of muscle cells
orientation of muscle cells
orientation of muscle cells to their tendon
Muscles that move together are…
Agonists
Muscles that just support are…
Fixators
What are the two types of skeletal muscle systems
Axial and apendicular
