Types of muscle tissue
This kind of muscle is found at the heart
What is cardiac muscle?
This term describes a muscles ability to forcibly shorten when stimulated
This connective tissue layer surrounds the entire muscle
What is the epimysium?
This is the thick filament of the myofibril
What is myosin?
This synovial joint type has a spherical end of bone surrounded by a cradle and it allows for movement in every direction
What is a ball and socket joint?
This type of muscle tissue is our only voluntary muscle type
What is skeletal muscle?
This characteristic describes a muscles ability to receive and respond to stimuli
What is excitability?
This term refers to a group of muscle fibers
What is a fascicle?
This band of the sarcomere is composed of the entire length of the myosin filament
What is the A band?
This synovial joint is not very widespread, the big example you should know is the cervical region of the vertebra (but it is also found as the radioulnar joints). It has uniaxial movement
What is a pivot joint?
This muscle type has know visible striations
What is smooth muscle?
This characteristics of muscle tissue describes the muscles ability to bounce back/recoil
What is elasticity?
This connective tissue layer surrounds each individual muscle fiber
What is the endomysium?
This regulatory protein acts as a key. When Calcium binds it frees the active site of actin
What is troponin?
These are pillows of hyaline cartilage in the knee that act as a cushion
What are the menisci of the knee?
This type of muscle can be found in the visceral organs expect the heart
What is smooth muscle?
This characteristic of muscle tissue describes the muscles ability to be stretched past resting length
What is extensibility?
This connective tissue layer surrounds each fascicle?
What is the perimysium?
This regulatory protein blocks the binding site of actin (it looks like a rope)
What is tropomyosin?
These ligaments cross each other and can be found on the inside of the knee joint
What are cruciate ligaments?
This structure found in cardiac muscle cells is important for cell to cell communication
What are intercalated discs?
Of the 4 characteristics of muscle tissue, this is the only one that is unique to muscle tissue
What is contractility?
This name describes the plasma membrane of the muscle fiber
What is the sarcolemma?
The t-tubule and 2 terminal cisterns collective make up this structure
What is the muscle triad?
These ligaments are found externally and laterally at the knee joint and are named after the bones the join to
What are the collateral ligaments?
